PROGRAM HISTORY: Though the last operational example, BuNo. 156608 of RVAH-7, was removed from the active inventory on November 20, 1979, the aesthetically pleasing North American A3J!A-5 Vigilante remains physically perhaps the most impressive large aircraft ever operated routinely from the deck of a U.S. Navy aircraft carrier. Even by standards extant nearly two decades after its operational heyday, the high level of achievement represented by the Vigilante's technological and mechanical sophistication remains extraordinary. Because of the innate versatility resulting from such farsighted engineering, some twentyplus years after first being introduced as an attack bomber, it was mustered out of service as perhaps the most effective and successful dedicated aerial reconnaissance platform in naval aviation history. Just as importantly, the Vigilante also stands as the naval aircraft high water mark for the North American division of today's Rockwell International.' It was, and still is the most advanced aircraft ever sold the Navy by that company, and it also has the honor of being the first combat aircraft of any type to be indigenously designed and I

developed in total by the company's Columbus, Ohio operation. . The latter was a feat of no small proportion, as the Vigilante was a complex and highly advanced aircraft with features that would set aircraft design precedent in many important areas for several decades to come. From its prototypical use of variable-area ramp-type intakes to its ill-fated.rearward ejection bomb delivery system, it was at the time of its debut, a far-sighted response to a variety of difficult and not easily assi'Tlilated military requirements. Among the many firsts claimed by this magnificent aircraft were the follOWing:

8. First variable inlet using horizontal ramp geometry. 9. First application of H-11 hot work tobl steel in fuselage machined frames. 10. First use of STRUX high-speed steel for landing gear struts. 11. First production f1y-by-wire control system.

The generic Vigilante concept was born during 1953 when North American engineering prodigy Frank G. Compton assembled a small team to study low altitude weapons delivery techniques. Compton had joined the company just prior to U.S. entry into WWII and had rapidly ascended through the ranks to become a primary engineering resource on almost all of the North American Columbus Division's indigenous aircraft projects. By 1956, he had become chief of preliminary design. The Columbus division itself had entered the North Americ.an fold as a result of production overloading that had emerged from a pre-Korean War surge in AF and Navy aircraft contracts. North American, still riding the favorable publicity tidal wave generated by the extraordinary successes of the P-51 Mustang, the B-25 Mitchell, and newer types such as the F-86 Sabrejet, had garnered enough post-war business to warrant the acquisition of additional production capacity. Accordingly, during September 1950, North American's "Dutch" Kindelberger (North American's chief executive officer) opened negotiations with the

1. First use of an airborne digital computer for bombl nay computations. 2. First bomb/nav system with inertial auto-navigator coupled to radar and television sight for check point acquisition. 3. First production heads up display installation. 4. First fully integrated autopilot and air data sys1em for bomb/nav weapon release solution. 5. First use of aluminum lithium alloy in aircraft construction. 6. First multi-mode Ku band monopulse radar with terrain avoidance features. 7. First use of slot deflector spoilers (no dead band) following joint R&D development with North American's F-107 program.

The "Vigilante" full-scale mock-up was quite similar to the actual aircraft with the exception of the intakes, the aft transparency, and the twin vertical tail surfaces.

government to lease the expansive Naval Industrial Reserve Facility at the Columbus, Ohio airport then occupied by the old and rapidly sinking Curtiss-Wright company. This immense plant, along with facilities bought from the Lustron prefabricated housing company, was taken over formally by North American shortly after negotiations began. It was occupied initially by the company during November and immediately utilized to meet P-51 and P-82 spare parts manufacturing requirements and sub·contract work transferred from Curtiss-Wright and North American's Downey, California plant. As the Columbus facility came on-line in the North American manufacturing program, Kindelberger directed the transfer of a management nucleus from Los Angeles to Columbus in order to build an integrated self-sufficient engineering/manufacturing facility there. The core of this nucleus was Chuck Gallant and George Gehrkens, who were appointed general manager and chief engineer, respectively. Following its assimilation into the North American fold, the Ohio plant became formally the Columbus Division. North American operated it initially as a Navy facility, and dedicated it to on·going navy programs. Later it would become a second-source production line for the AF's F-86 and F-100 fighter series. Aircraft types run through the Columbus facility from its birth through the advent of the Vigilante included the AJ-2, the AJ-2P, the F-86F, the F-86H, the FJ·2, the FJ·3, the FJ-4, the FJ-4B, the F-86 series, the F-100C, the F-100F, the T-28B, the T-28C, and later, the T-2B and T-2C, and a small number of experimental and limited production types such as the FJ-4F and the YAT-28E. During this period, the Columbus Division grew from 1,600 carry-over Curtiss-Wright personnel to more than 17,000 employees. A total of 3,280 new aircraft were produced and 1,260 other aircraft were modified, remanufactured, or partly produced under subcontracts. Included in the latter group were T-6Gs, B-29s, R4Ys, T·28Ds, and F8U fuselages. Frank Compton (who had followed Gehrkens to Columbus) and his small design team, like many similar teams scattered throughout the U.S. aerospace industry, by the early 1950s had become disciples of the generally accepted aircraft design philosophy combining thermonuclear weapons with advanced aeronautical technology. Like other aircraft engineers of the day, they were enamored with the sheer destructive force and broad area damage incurred by a nuclear explosion, and they

were quick to take advantage of the relatively loose CEP (Circular Error Probable) requirements that had resulted. Growing from the latter was a revived interest in an old and inaccurate, but decidedly appropriate weapons delivery technique called toss bombing (With theme variations such as loft and over-the-shoulder release). Toss bombing's singUlar attribute was the time it permitted a delivery aircraft to extricate itself from a given blast area. Nuclear explosions were known to generate strong, near-sonic shock waves that moved outward concentrically from the point of detonation. The strength of these shock waves diminished in relation to their distance from ground zero, and it thus was important for a delivery aircraft to be as far from the initial explosion as possible in order to minimize their effect. During the early 1950s, when Compton and his team began to explore aircraft designs optimized for nuclear weapons delivery, two significant problems became apparent: (1) targets were difficult to locate from aircraft when the mission profile required weapons delivery over very long ranges at very low altitudes; and (2) the sonic speeds achieved by post-nuclear-explosion shock waves dictated that delivery aircraft be capable of transonic to supersonic performance in order to escape their affects. Additionally, demands on the nuclear weapons industry to create bombs transportable by fighters had resulted in a new generation of small weapons that, though remaining remarkably powerful, required much more precise target placement in order to most effectively utilize their lower yields and reduced blast effects. The Navy, by this time, already had integrated several large, nuclear-capable aircraft into its inventory. North American's piston/jet-engined AJ-1/·2 Savage series had been Mk.6 nuclear weapon-capable since the late 1940s, and another piston engined type, the Lockheed P2V-3C Neptune, one member of a large Lockheed patrol aircraft family, also was nuclear weapon and carrier capable. These aircraft represented first-generation delivery systems with limited accuracy and virtually no real ability to protect themselves from enemy defensive action or the affects of bomb blast·generated shock waves. It therefore was apparent the Navy soon would be seeking more advanced replacements, and the service's intermediate step of ordering Douglas' jet-powered (but SUbsonic) A3D Skywarrior, had by 1949, underscored this point to most of the major manufacturers. Although a firm requirement had yet to emerge from the Navy's Bureau of Aeronautics (BuAer) calling for a

nuclear·armed aircraft to replace or complement the vulnerable Savage, Neptune, and Skywarrior (and thus maintain what the Navy then still viewed as its role in the U.S. strategic nuclear deterrent force), Compton, Gallant, Gehrkens, Mac Blair (manager, aerodynamics group), Reggie Clark (vice president in charge of production), and Wilbur Mitchell (avionics specialist) during November 1953, nevertheless initiated preliminary studies exploring configurations optimized to fulfill such related mission profiles. Later joining this group during mid-1955 was John Fosness as program manager. Concerning this period, Gehrkens later would recall, "The Vigilante proved to be the culmination of many different program by-products. Difficulties with the dropping of weapons from the conventionally configured bomb bay of the B·45 at high-subsonic speeds gave birth to the linear bomb bay concept; difficulties with the interception of Soviet Tupolev Tu-95 Bear bombers at high altitudes (purportedly undertaking reconnaissance flights over the continental U.S. during 1954 and 1955) gave birth to the idea of adding auxiliary rocket propulsion systems (initially monopropellant, and later, bipropellant) to fighters (most notably, the FJ-4R); and navigation problems that became apparent during long-range bombing missions were explored using the autonavigation concepts generated by the Navaho intercontinental range missile program. "Frank Turner, a Navy AJ-2 squadron commander, was the first to catch my attention with the ramifications of low altitude flight and radar evasion. He had calleq to tell me about a Savage flight he had made from Barcelona, Spain to Paris, France and back wherein he had not been detected by any radar, foreign or otherwise, during the entire trip. "By the time Frank and I and others got started on NAGPAW, all of these end products effectively were in place for us to utilize during the conceptual stages of the project. Soon the concept evolved into a small, singleplace, high-subsonic speed, pure jet with moderately swept wings, a low tail, an inertial navigation system, a small radar, and an aft-facing linear bomb bay between the jet exhausts." The aforementioned problems with 'accuracy and shock wave avoidance proved difficult to overcome, but as design studies began to mature, solutions resulted. Accuracy was tackled by interfacing an inertial navigator and simple low-resolution "shore-line checkpoint" radar; and post-explosion shock wave avoidance was achieved

through (1) mechanization of the bombing system to permit high loft release of the weapon, and (2) afterburning turbojet engines to enhance acceleration, rate of climb, and turning performance. Assuming the target's coordinates were accurately known with respect to well-defined shoreline checkpoints prior to mission initiation, minimum navigation equipment alignment time on the carrier deck was expected to be required. Following launch, the warmed-up inertial navigation system would be calibrated at the moment the predetermined shoreline checkpoint was crossed. The inertial system then was expected to be sufficiently accurate to guide the aircraft directly to the target. Even while operating at sea level altitude or "on the deck", from the shoreline the aircraft would be brought to within target or off-set point visual identification range. At that moment, a run-in and pitch-up maneuver (i.e., toss bomb) would be undertaken, thus positioning the aircraft in a climbing, vertical attitude directly over the target. At the appropriate moment, the weapon would be released rearward. Inertia would cause it to continue to climb vertically, initially in parallel with the aircraft; gravity eventually would take over and stop the ascent. At that point, the weapon would flip over, stabilize aerodynamically, and descend onto the target. The aircraft, in the interim, would pitch and roll into a horizontal attitude (via the classic Immelman) and accelerate away from the target and blast area. Addition of a rocket booster unit during the course of design development, to be used for very high altitude target penetration only, led to a bomb train study (consisting of the bomb and two fuel tanks in tandem) to include attachment of a bi-propellant rocket motor to the rear fuel tank. The two linear bomb bay fuel tanks which normally were to contain JP-4 would carry hydrogen peroxide (H,O,), instead. The rocket motor was to use JP-4 from the aircraft fuel system through a quick disconnect coupling. The H,O, contained in the bomb bay tanks were to feed the rocket engine, also through a quick disconnect coupling. The mission profile called for rocket propulsion, starting at Mach 1.6 and accelerating to Mach 2 + while climbing from 50,000 ft. to 70,000 ft. Stabilized penetration to the target would take place beginning 100 n. mi. before reaching the initial point. At the initial point, the H,O, contained in the bomb bay tanks would be depleted, the rocket engine jettisoned, and the weapon catapulted rear-

ward on signal from the bomblnavigation system. The H,O, tanks would remain attached to the weapon, stabilizing it during ballistic flight to the target. Testing of the rocket engine configuration in two highly modified FJ-4s, designated FJ-4Fs, was consummated during April 1957. Having been initiated on August 12, 1955 as the NA-234 with a monopropellant rocket, this project was continued under the NA-248 model designation and formally moved into the hardware stage on May 28, 1956, with a bipropellant unit. Two aircraft, the second and fourth production FJ-4s, BuNos. 139282 and 139284 respectively, were modified to include North American AR-1 rocket engines mounted above the exhaust nozzles of their Wright J65 turbojet engines. Flight testing at North American's Columbus plant and the Navy's Patuxent River, Maryland facility verified the viability of the booster rocket system. However, basic aircraft performance utilizing only the jet engines, by this time had proved suitable for mission requirements and thus the rocket propulsion system was declared redundant. Shortly afterwards the program was cancelled. Amazingly, according to Frank Compton, during the course of flight test work related to this project, one of the two FJ-4F testbeds achieved a speed of Mach 1.4 at 70,000 ft. During January 1954, under the aegis of the acronym NAG PAW (North American General Purpose Attack Weapon; this concept evolved during a meeting between Frank Compton, Capt. Noel Gayler, and George Gehrkens during late 1953), a seminal design was established. Incorporating such advanced features as a linear bomb bay-type rearward-ejecting bomb release system capable of functioning in a LABS (Low-Altitude Bombing System) toss bombing mode, a weapons delivery system that integrated the inertial navigation unit with a small, nose-mounted radar to locate targets, and operational rocket propulsion systems for short-term increases in acceleration and maximum speed, the proposed twin-jet engined, single-seat NA-233 was found by the BuAer to be complementary to its arguments favoring a super-carrier-centered Navy nuclear deterrent force. Almost solely because of this the Navy strongly supported it as a possible production program when the Fiscal 1955 budget was presented to Congress. The original NAG PAW study (sent to the Navy as an unsolicited proposal during January 1954) had been optimized as a low level penetrator, and wing geometry had been selected accordingly. Wing area, however, had

been determined by the Navy's zero wind catapult requirements and the resulting wing loading proved too low for acceptable low-altitude ride qualities. During the second design iteration wherein trade-offs in the form of ride qualities vis wind-over-deck requirements were explored, OPNAV changed the ground rules making high altitude, Mach 2 penetration the primary performance objective, and low altitude capability secondary. This changed occurred during January 1955 and at this point NAGPAW quickly was revised to meet the new Navy specification. The revised proposal was submitted to the BuAer by North American during early April 1955. Consequent to this, the name Vigilante formally was proposed by North American as the new aircraft's name.' A letter of intent to proceed was received by North American on June 29, 1956, and a contract for $86 million to produce two YA3J-1 s and a single static test article was signed the following September 17. The change in performance extremes resulting from the Navy's decision to totally restructure the NAGPAW specification had quickly resulted in monumental changes to the basic NAGPAW design. To accommodate the revised performance envelope, major studies were required by the North American design team to generate a compromise wing configuration optimized for operation at both high and low speeds (the latter in order to meet carrier landing and takeoff speed constraints). No aircraft of the proposed NA-233's size (the revised mission objectives had caused across-the-board increases in size and weight and the addition of a second crew member to handle the rapidly increasing cockpit workload) successfully had met such stringent requirements previously, and it therefore became a major challenge to generate a workable compromise. As there was virtually no viable variable-geometry experience base to work from during the mid-1950s, wing sweeping was discarded at an early stage. The conventional fixed wing design thus became a critical element in achieving the Navy's performance objectives and the resulting configuration, though aesthetically pleasing, was significantly less efficient than it would have been 'Although the NAG PAW program was accepted by the Navy's' BuAer as a proprietary concept, Chance Vought learned of North American's effort and also submitted an unsolicited proposal just two months prior to the award date. Ironically, (or coincindentalIy?) Vought had picked the name Vigil/ante [sic) for their proposed aircraft.

if the Navy's performance requirements had been somewhat less stringent. Compton's team eventually generated a compromise configuration that on paper, at least, permitted the broadest performance envelope of any large aircraft built up to that time. Still referred to as the NA-233, the new NAGPAW proposal had a 769 sq. ft. low thickness/chord ratio wing with near-full-span blown flaps and a resulting performance envelope that came close to meeting the BuAer's zero-wind-over-deck specification while still allowing a maximum speed of Mach .95 at sea level and Mach 2 at 40,000 ft. Though the sea level performance figure did not meet the Navy's Mach 1 + requirement (to do so would have meant a significant reduction in \'o(ing area, and thus a loss in altitude and payload performance) the achieved specified high-altitude performance was considered excellent. A lengthy series of wind tunnel tests were conducted to verify the new design's applicabilty to the performance and flight characteristic profiles North American had generated on paper. Five models were utilized to determine the performance and stability and control characteristics, air loads, and aeroelastic effects; and two duct models were used to determine the duct recovery and internal flow characteristics. Four additional models were used to investigate store and store delivery characteristics. Two other models were used to investigate aircraft spin characteristics, and yet another

was used to investigate exhaust efflux patterns and afterbody drag. Flutter models also were developed, these being dynamically similar to the NA-233 base design and tested in a number of different tunnels. Lingering during the course of NAG PAW/Navy deliberations was the then-still-ongoing argument between the Navy and the AF over which of the two major services would accommodate the nation's strategic nuclear deterrent requirement. Historically, this disagreement stemmed from the post-WWII U.S. policy preventing the storage or handling of nuclear weapons on foreign soil (with the exception of Great Britain). This created the dilemma of having targets that at the time were not physically accessible to AF tactical aircraft. These targets thus became the responsibility of the Navy's carrier-borne forces and directly gave birth to the requirement leading up to the AJ-1. From that point forward, the Navy maintained that its carrier and submarine forces offered the more viable (and militarily more flexible) alternative to the AF's astronomically expensive strategic missile and bomber forces. Complicating things for the AF was an on-going debate over the anachronistic Convair B-36 and its many costoverruns and performance failings (all of which eventually would be swept under the carpet in the name of national security). By the beginning of 1957, when the NAGPAW design had been all but finalized, the Navy/AF strategic weapons delivery disagreement effectively had become ALTITUDE ANO TIME PLOT FOR DISCLOSED VERTICAL RELEASE MODE Effectiveness of typical weapon and ground-to-air missile systems.

perhaps the single most blaring example of inner-service rivalry in the 000. Because of this, and since NAGPAW was being designed primarily as a bomber with a wide variety of nuclear weapons delivery techniques, there remained considerable debate within the Navy when Fiscal 1958 and 1959 budgets were being created over whether to buy the new aircraft in quantity. One faction, led by Garrison Norton, then Assistant Secretary for Air, argued that strategic bombing was not the Navy's mission. He maintained that buying the aircraft would represent yet another attempt to invade the AF's mission domain. It consequently would become the harbinger of further inter-service acrimony. Fortunately for North American, a less passive Navy faction argued that NAGPAW also was capable of performing low-altitude missions while carrying conventional weapons. This latter group eventually prevailed, clearing the way for Navy program personnel to formally request production funds in its Fiscal 1959 budget request for what now officially was referred to as the A3J. The Navy's request subsequently was approved by 000, and shortly afterwards, money was appropriated by Congress. By February 1956, the final specification and configuration criteria had been established, preliminary wind tunnel testing was complete, and the NA-233 full-scale mockup was ready for review. The formal mock-up review board was held during March 1956, at which time the mock-up already was quite firmly fixed in configuration. Changes eventually would occur in the rear cockpit transparency design, some aspects of the intake configuration, the linear bomb bay tail cone (the mock-up was equipped with a clam-shell design), and the vertical tail surface arrangement (the mock-up was equipped with twin vertical tail surfaces). In general, however, it was similar in most respects to the prototype aircraft that soon would follow. Construction of the two prototypes took nearly two years to complete. Engineering drawing release was granted during June 1957, tooling starts were undertaken during November, and actual fabrication of the first aircraft formally was initiated during August. On May 16, 1958, the first YA3J-1, BuNo. 145157, was rolled out from North American's Columbus plant doors for the first time. Three months of static ground and taxi testing at the Columbus airport followed, with chief company test pilot Dick Wenzel piloting the General Electric YJ79-GE-2 powered aircraft during its first flight on August 31, 1958. Wenzel's post-first flight report was lengthy and detailed. After reviewing the aircraft's physical status, special first flight restrictions, cockpit ergonomics, and

taxi characteristics, he noted the actual flight events as follows: Take-off

augmentation and damper off, 45° flap, 6° nose up stabilator trim and neutral lateral and directional trim. Maximum afterburner thrust was selected immediately after the brake release and nose wheel steering was utilized to lift-off. Acceleration was high and the take-off roll was approximately 2,500 ft. with a 10 knot headwind component. Lift-off occurred at approximately 150 KIAS with very little rotation required. Landing gear retraction did not produce any significant trim change and the cockpit noise level decreased when the gear doors closed at about 180 KIAS. Minimum AS was then selected and the climb continued at about 180 KIAS and the flaps retracted in increments to allow longitudinal retrimming due to the large nose down trim change due to flap retraction. Moderate flap buffet was encountered at deflections greater than approximately one-half flap. "Control effectiveness about all axes was satisfactory at and immediately after lift-off. Immediately after lift-off, a slight nose-over was made to accelerate the airplane

in ground affect to approximately 160 KIAS and then the airplane rotated slowly and approximately 180 KIAS was maintained. The forward view was excellent throughout the take-off run and through the transition to flight. "After flap retraction, the climb was continued at MRT and 200 KIAS to 10,000 ft. Hp, where the chase pilot conducted an exterior inspection. All doors and surfaces were normal except the fire doors which were partially depressed and remained that way throughout the flight." Climb "An MRT climb was made from 10,000 ft. to 35,000 ft. Hp at speeds considerably below the optimum climb speed schedule. The FJ-4S chase airplane climb performance (MRT) was identical to that of the A3J-1. "During the climb between 20,000 ft. and 30,000 ft. Hp and at .80 IMN, the electrical and augmented systems were engaged. The normal (position), lateral, and directional trim controls also were engaged and used for the remainder of the flight. Lateral trim sensitivity was high during the climb and SUbsequent cruising flight. Control about all axes was satisfactory." Cruise

"It was intended to accelerate from .90 to 1.10 IMN.

)The servo valves were activated by cables hooked to the flight controls which served as a back-up to the fly-by-wire arrangement. Normally, moving the stick would send a signal via wi re to the servo valve.

However, radio failure precluded this run. Consequently, the maximum speed attained was .92 IMN at 35,000 ft. Hp. Directional control forces were very light." Speed Brake Characteristics "The speed brakes were fully extended at .85 IMN and 35,000 ft. Hp in a shallow dive. Speed brake effectiveness was good and relatively high. A mild nose down trim change followed by a very mild nose up trim change occured during speed brake extension. Mild to moderate airframe buffet was encountered with the speed brakes extended. A sharp 'crack' was felt and heard as the brakes opened. This disturbance was undesirable. "Following the first brake retraction, the speed brake indicator showed 'barberpole'. Following a subsequent retraction, the speed brake indicator showed "In". Low Speed Investigation "Control effectiveness was investigated in the 'PA' configuration between 25,000 ft. and 20,000 ft. Hp using 50° and 40° of flap. Lateral control response for small deflections was low, but appeared to be slightly better at 50° of flap than at 40° at 145 KIAS. However, the effectiveness was adequate at 40° of flap and the minimum speed investigated was 140 KIAS with 40° of flap. Control was adequate about all axes to 140 KIAS and no unusual,characteristics were noted except moderate f1ap-

horizontal stabilator buffet. The chase pilots observed that the tips of the horizontal stabilators were oscillating through a double amplitude of 1 to 1-1/2 in. with the flaps at either 50° or 40°. Very little flap movement was detected, indicating that the buffet was due to horizontal stabilator shake. "Forty degrees of flap was preferred for the first landing because of the higher pitch attitude which would allow greater nose wheel clearance during a relatively

high landing speed." Landing "Landing was made at approximately 39,500 Ibs. gross weight in smooth air with 40° of flap, speed brakes closed, manual control and augmentation and yaw damper off. Touchdown was made at 140 KIAS on the main gear with power on. The approach was started at 160 KIAS at the 180° position and approximately 145 KIAS was attained "over the fence". The pilot's view over the side and over the nose during the approach and landing was excellent. Longitudinal control forces were high and made landing flare difficult. Immediately after touchdown an attempt was made to hold the nose wheel off, but because of the high forces, the nose wheel was allowed to touch down after a short run. Airplane deceleration was low. No attempt was made to brake the airplane (brakes checked at the 6,000 ft. marker) until braking for the turn off at the end of the runway was initiated with approXimately 2,000 fl.

of runway remaining. The brakes were relatively cool after

touchdown. " General "The chase pilot observed fuel dumping intermittently from the fuel vent pipe. "With approximately 5,000 Ibs. of fuel remaining, the fuel quantity indication system showed approximately 600 more Ibs. of fuel with the gear and flaps extended than in the cruise configuration.

"The cockpif'noise level was high throughout the flight (and on the ground, canopy closed) and was particularly annoying at about 80% rpm where a hollow howl was encountered.

"On the initial approach for landing, the windscreen frosted over. Canopy defrost and wiping the after half of the screen did not provide a satisfactory view over the nose until canopy defrost had been on for about 5 minutes

which produced an uncomfortably high cockpit temperature and head buffeting. Defrost flow modulation is required (windscreen defrost ducts were not installed because of the interim installation of thick plexiglass windscreen). "The inside canopy manual release could not be operated because of the high forces encountered." Conclusions ''The only major deficiency revealed within the scope

of the flying performed on this flight was flap-horizontal stabilator buffet. Lateral control effectiveness will require further evaluation. Although a number of malfunctions were encountered, none were critical."

Malfunctions 1. The fire doors were partially open during the entire flight. 2. The yaw damper disengaged frequently, requiring resetting. 3. Lateral control forces increased markedly when the electrical system was selected. 4. Fuel sequencing system would not maintain the 625 gais. sump level after selecting 'Transfer' momentarily. 5. The nose gear door remained fully open after gear extension. Following the second gear retraction, the nose

gear showed 'barberpole' and the chase pilot observed that the nose gear door was open approximately 2 in. and the right main gear door was gapping approximately 1/4 in.

6. NO.2 generator did not cut in as designed. The No.2 engine was started first and the NO.2 generator could not be 'Reset'. The No.1 generator cut in as designed and simultaneously the No.2 generator cut in. 7. The brakes were very spongy and the pedais did not return completely after release. 8. The speed brake indicator showed 'barberpoled' following the first speed brake retraction, but showed 'In' after a subsequent cycle. 9. The pitch trim indicator was inoperative. 10. UHF transmissions were initially garbled and then UHF communications were lost completely. 11. Fuel was dumped intermittently through the fuel vent line.

12. Three tries were required to lock the canopy closed." Following successful completion of the first flight, subsequent work on the two prototype YA3J-1s moved ahead rapidly. The second aircraft, BuNo. 145158, entered the company flight test program several months after BuNo. 145157 and immediately undertook preliminary aeroelasticity and control systems tests. Unfortunately, this aircraft, after completing 49 flights and 66.4 flight hours, was destroyed on June 3, 1959, when hydraulic and electrical sys1em failures caused loss of control. As the initial run of nine A3J-1s (BuNos. 146694 through 146702) became available for flight test during the middle of 1959, these aircraft joined the surviving prototype and quickly were allocated for Navy Preliminary Evaluation (NPE), Board of Inspection and Survey (BIS), and other miscellaneous trials at the Navy's Naval Air Test Center facility at Patuxent River, Maryland. Initial carrier trials were undertaken by NATC-assigned A3J-1, BuNo. 146697 on July 22, 1960, when the first successful carrier landings and takeoffs were completed aboard the USS Saratoga (CVA-60). A breakdown of the initial1est program assignment for each of the first sixteen A3J-1 s up to March 1, 1962, was as follows: SuNo. 145157 145158 146694 146695 146696

North American and several major factions in the Navy considered the Vigilante an extraordinary aircraft, and thus one worth promoting. Indeed, to underscore their claim during 1he first stages of what was soon to become a bitter fight with Congress to keep the Vigilante program alive, early production examples of the aircraft were utilized to set several world speed and altitude records. In the former category, noted aviatrix and then-president of the Federation Aeronautique Internationale, Jacqueline Cochran, on June 6,1960, became the first woman to fly Mach 2 when, as an occupant of the bombardierl navigator's compartmen1, she participated in a speed run over southern Ohio that reached Mach 2.02 (at 47,000 ft.) This was followed by a new world altitude record for class when, on December 13, 1960, a Vigilante carried a 1,000 kg (2,204.62 lb.) dummy payload on a zoom profile flight that peaked at 91 ,451 ft. Flying the mission from North American's Palmdale, California field facility, it exceeded the previous July 13,1951, Soviet "RV" experimental aircraft mark by 24,354 ft. The crew consisted of Navy Cdr. Leroy Hea1h and Lt. Larry Monroe, both of the NATC. Heath later was awarded the Distinguished Flying Cross while Monroe received the Air Medal. At least two A3J-1s, BuNos. 147856 and 147857, from the second production batch, were sent to the Naval Weapons Evaluation Facility (NWEF) at Kirtland AFB, New Mexico, where they became involved in cruciai nuclear and conventional weapons delivery testing. These tests had, in fact, been preceded by a lengthy series of bomb navigation system trials at North American's Columbus, Ohio facility and Patuxent River NAS. Initial bomb system 1rials under the aegis of North American had gotten underway during February 1961, and had led rapidly to the conclusion that deficiencies were significant and numerous; radar, television, terrain avoidance/contour mapping, visual air-to-ground modes, and F10F bombing computer anomalies were pervasive. The Navy, North American, and all affected subcontractors decided that corrective action should be undertaken immediately and tested utilizing A3J-1s BuNos. 146702, 148932, 149278, and 149281 from the second and third production batches. Navy evaluation of the AN/ASB-12(XN-2) Bomb Director Set with the F10F Bombing Computer was conducted at Patuxent River during the period from June 4 through 14, 1962. Twelve bombing flights totaling at 13.4 flight hours were conducted on the NATC cinetheodolite range utilizing A3J-1, BuNo. 146702. Actual drops were scored using Mk.83 low drag bombs during all-weather level flight deliveries at Mach .9 and 20,000 ft. Mk.89 practice bombs were utilized during all-weather loft and over-theshoulder (toss-bomb) deliveries at Mach .9 and 500 ft. run-in altitudes. A run-in heading of 340 0 was utilized for all deliveries. Analysis of the bombing trials determined that F10F steering mechanization resulted in a straight course track during all-weather level flight deliveries and during maneuvering mode deliveries to pull up. It also was determined that the steering signal after pull up was usable throughout the maneuver. Visual air-to-ground modes of the general purpose radar unit were not evaluated. Following the trials it was concluded that bombing accuracy of the all-weather, level flight mode was satisfactory at the delivery condition evaluated with a maximum cross wind component of 20 kts. Nine of twelve scored bombimpac1s were within the specification CEP. Bombing accuracy of the all-weather loft and over-the-shoulder modes was unsatisfactory, however, at the delivery conditions evaluated (with a cross wind component of 20 kts.) as only one of six over-the-shoulder bomb impacts was within the specified CEP. The Navy again recommended North American undertake modifications to the system to refine its accuracy. Other anomalies also had surfaced during this period, including a number related directly to the airframe and its components. Included were: insufficient structural integrity of the flap boundary layer control system com-

ponents; insufficient structural integrity of the main gear wheel bearings; excessive fuel spillage from the fuel cell' vent line; improper assembly of the wing fold control unit; inadvertent hard-over signals in the nose gear steering system; frequent failures of the station 556 fuselage bulkhead assembly; unreliability of the radar altimeter; implosion failures of the radar antenna front dish; poor reliability of cabin air conditioning system components; insufficient structural integrity of the drop tank fuel air pressure disconnect fittings; failures of the engine fire shutoff relay; incompatibility of the air refueling probe ,J,ith the Dalmo-Victor drogue; complexity of determin)ng bombing computer differential ballistic wind offset; poor reliability of the bomb bay fuel can transfer and dump system air valve; frequent failures of the mounting bolts associated with the engine airflow modulator roller assembly; and unsatisfactory operation of the canopy manual internal release handle. In general, the majority of these discrepancies were of minor importance and with select exceptions, easily corrected. Persisting, however, were increasingly frustrating difficulties with the linear bomb bay and its rearward ejecting bomb system; it steadfastly reiused to succumb to redesign and re-engineering. Anomalies remained with the radar (noise modulation and target bloom); the television (lack of contrast and acquisition range); the autonavigator (excessive warm-up time); the terrain avoidance system (lack of suitable ground calibration and alignment; lack of instantaneous vertical speed indicator; and lack of minimum range indication); the F1 OF bombing computer (inadequate steering signal and unsatisfactory bomb director set data); the radar altimeter (excessive errors); the air data computer (inaccurate airspeed position); the terrain avoidance radar system (inadequate radar antenna pitch stabilization; poor stabilization in autonavigator mode; lack of adequate centerline indication; lack of altitude selection capability of the radar altimeter warning light and insu(ficient dimming control range); and the air-to-ground system capabilities (excessive radar oscillation and azimuth cursor strobing). Actual A3J-1 nuclear weapons drop tests were initiated at Kirtland AFB, New Mexico in response to a February 9, 1960, directive that eventually became a phase of the Service Acceptance Trials. Initially, aircraft BuNo. 147857, received on April 28, 1962, was assigned as the sole test aircraft during the Initial Trials Phase (ITP). Later, it would be joined by BuNo. 147856. The purpose of the ITP was to determine the adequacy and reliability of the nuclear weapons provisions in the Vigilante and to determine the acceptability of the aircraft for service use for the delivery of nuclear weapons. BuNo. 147857 was representative of fleet configured A-5As (production numbers 34 through 45), but had additional test instrumentation and a test modification to the armament circuitry. It was delivered with known deficiencies in terrain avoidance and visual bombing modes. Nonproduction MOD C pylons were used as required by operating limitations. The following nuclear weapons, expendable store train items, and weapon adaption kits were utilized during the tests: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11.

Under the aegis of VX-5, DET A, the Vigilante nuclear weapons test program commenced on June 26, 1962, and continued for the following six months. It ended formally on December 31. Test objectives were to determine: (1) the effect of environment on the nuclear weapons and their systems; (2) separation characteristics of all nuclear stores in all available release modes; (3) ballistic characteristics of internal store trains in all available release modes; (4) adequacy and reliability of

North American's Columbus Division A3J-1/A-5A production line on March 12, 1962. Today this facility is effectively life/ess and is awaiting conversion to C-17 production.

operation of the T-375 AMAC (Aircraft Monitor and Control) System; (5) adequacy and reliability of the armament release circuitry; (6) adequacy and reliability of the ASB-12 and ASN-26 systems as .they affected bombing CEP and aircraft escape; (7) adequacy of the aircraft as a nuclear weapons delivery platform; (8) adequacy of operation of the thermal closure; and (9) compatibility of nuclear stores with the aircraft as necessary to satisfy Sandia Corporation requirements for certification. Tests that were not completed included the drop tests of the Mk.43 internal store train and the drop tests of weapons scheduled in the visual dive-toss mode. The lalter were eliminated due to the inability of the bomb directing set to function adequately and provide safe execution of the required maneuver in this mode. During the six month test program, a total of 136 flights were completed for a total of 183.1 flight hours. It was concluded that the A3J-1, throughout most of its applicable flight envelope, was a superior bombing platform. Unfortunately, its linear bomb bay and associated rearward bomb ejection system, around which its mission profile was being generated, were not of comparable dependability. Numerous difficulties arose not only with the radar and bomb/navigation unit, but also with the actual mechanical system used for supporting and ejecting from the aft end of the aircraft the various store trains. Specifically, difficulties arose with electrical and mechanical connections, weapons tunnel temperatures, the ejection gun, separation of the store trains from the aircraft, store train stability following ejection, and a host of other anomalies that remain too numerous to list here. Not too surprisingly, during the weapons release tests, it was discovered that when stores were transported conventionally (Le., on underwing pylons), minimal release difficulties were incurred. The aircraft was found to remain quite stable during the release sequence, and asymmetric yaw, even when carrying and releasing asymmetrical loads, was negligible, at worse. While troubles with its bombing system continued to beset the Vigilante, another difficulty of even greater magnitude was beginning to surface. The extraordinary

performance and compleXity of the aircraft had not come cheaply. The technological hallmark it repr~sented had cost millions of research dollars (Navy funding for the A3J-1 during Fiscal 1962 was $177.9 million; funding for 1963 was over $200 million) and Congress now was beginning to balk at unit cost figures that rapidly were approaching $9 million. Other Navy aircraft programs offering hardware of comparable capability at significantly less cost also were moving ahead on schedule. Oniy in speed was the Vigilante markedly superior, for it was becoming readily apparent that aircraft like Grumman's lumbering A-6 (notwithstanding its high vulnerability) easily could deliver weapons as accurately. Though long-term solutions to most of the linear bomb bay anomalies were thought possible, the expense coupled with the time required for correction were not considered palatable by the Congress-and some segments of the Navy. With these facts in mind, North American was quick to promote the altributes of their second-generation A3J-21A-5B. With accelerated production rates and the tapering off of the bombing system development program (the direct result of the previously mentioned inadequacies), North American claimed that a unit production cost of slightly less than $5 million might be possible (excluding government furnished equipment and weapons or sensors; the lalter, as concerns the RA-5C, caused the unit cost to exceed $16.5 million by 1964). Unfortunately, it was at just this very stage in the Vigilante's controversial and short history that the Joint Chiefs of Staff reached a somewhat acrimonious accord rescinding the Navy's right to a piece of the nuclear deterrent mission. The AF thus became the primary deterrent force, leaVing the Navy biased toward conventional tactical responsibilities. Part of the fall-out from this reorientation was the realization by both the Navy and North American that the Vigilante suddenly had become a superb airframe and propulsion system with no reason to exist. They now reviewed the NA-233's mission objectives and, in order to keep the program bUdgetarily alive within the constraints now placed on the Navy's limited strategic defense responsibilites, began selling the design to Con-

gress as a low-level attack aircraft optimized to carry conventional weapons. Consequent to this, North American now presented the Navy a selection of advanced Vigilante configuration studies that offered improvements in areas considered shortcomings in the original A3J-l configuration. An immediate step was to dramatically upgrade the aircraft's volumetric efficiency and thus permit an increase in fuel capacity and non-weaponry payload. This created an aircraft with substantial range, while expanding mission options to include tactical weapons delivery (by hanging weapons externally on wing pylons) and reconnaissance. Additionally, and perhaps most importantly, the Navy reciprocally agreed to relax its stringent zero wind-overdeck takeoff requirement. This, coupled with the improved thrust offered by the J79-GE-8 found in lateproduction A3J-l s, an associated increase in engine intake duct capture area, the introduction of blown leading edge flaps (and the deletion of blown trailing edge flaps), and a dramatic increase in trailing edge flap span and chord (and thus, area), produced decided improvements in low-speed and high-altitude performance while allow-

ing a 60% increase in gross takeoff weight (to just over 80,000 Ibs.-which also led to upgraded braking capacity to accommodate the increased dynamic loads). In order to expedite the new Vigilante version's service introduction and consequently to add credence to then-on-going Congressional arguments in favor of the Navy's strategic deterrence role, approximately mid-way through the Model NA-269 production contract (consummated on November 16,1959, and calling for 52 A3J-ls), a decision was made to complete the eighteen remaining airframes, from 269-35 through 269-52, as the first of the dramatically reconfigured A3J-2s. The first of these, BuNo. 149300, following conventional ground and taxi tests, was flown for the first time on April 29, 1962. The A3J-2, later redesignated A-5B, had profitted considerably from the lessons learned from the A3J-l/A-5A. The improvements in high lift devices, the increased wing area resulting from the enlarged flaps, and the increased fuel capacity resulting from the additional fuel tanks mounted on the top side of the fuselage (sometimes referred to as the "top-cap" mod and creating a total redesign of the upper fuselage fairing and related canopy

details) led to a significantly more capable combat aircraft-though one that, as a result of the Navy's rescinded nuclear deterrence role, effectively was stillborn. In fact, this latter dilemma had become of paramount importance during the waning months of 1961 when it became a certainty the AF would be victorious in its battle with the Navy over the question of deterrence. A long-standing and legitimate need for Navy fleet reconnaissance capability now provided justification for newly appointed Secretary of Defense Robert McNamara to keep the Vigilante in production. After being granted approval by the tri-service Darrow tactical reconnaissance board (which considered all military systems of this nature with the idea of eliminating overlap and integrating analysis and control systems), the resulting aircraft, which was generated in very short order under the auspices of the NA-269 model designator, offered the payload capacity required to accommodate the side-looking airborne radar (SLAR) and numerous optical sensors specified for the Navy's reconnaissance mission. Utilizing the basic airframe of the limited-production A3J-2, the new aircraft, initially referred to as the A3J-3 (and sometimes, the A3J-3P), and later as the RA-5C, was to prove the definitive version of the Vigilante. By the time the Navy's reconnaissance requirement resulted in a redirection of the Vigilante production effort, the first 18 A3J-2s were too far along in the production process to be quickly reconfigured to the reconnaissance configuration. Accordingly, all 18 aircraft were completed to the A3J-21A-5B standard and the first production example was rolled out for the first time during September 1962. Only two A-5Bs, BuNos. 149300 and 149302, were delivered to the Navy under the aegis of that designation. Another four (BuNos. 149301, 149303, 149304, and 149305) of the 18-count batch were delivered as YA-5Cs, and though lacking reconnaissance systems, were utilized by VAH-3 in an interim role as RA-5C trainers during late 1963 and early 1964, .prior to receipt by that unit of fUll-Up capability aircraft. The remaining twelve A-5Bs, BuNos. 149306 through 149317, were retained at Columbus as undelivered pending a decision concerning their conversion to RA-5C standard. The first purpose-built RA-5C, BuNo. 150823 (preceded by BuNos. 149300 and 146699-which flew for the first time as an A-5B and A-5A, respectively), incorporating the major design changes peculiar to the A-5B while optimized to carry an extensive array of tactical reconnaissance equipment (including frame cameras, panoramic cameras, side-looking airborne radar [SLAR], and

a complement of electronic countermeasures equipment fully capable of dealing with advanced electronic warfare scenarios) in a specially designed ventral canoe, was rolled out for the first time during the early summer of 1962 and flown for the first time on June 30. Systems and performance tests were initiated almost immediately afterwards with the majority of these being conducted at the Naval Ordnance Test Station, China Lake, California.

j

Conversion of all eighteen A3J-21A-5B standard aircraft to RA-5C standard eventually took place, alongside aircraft purpose-built to the RA-5C specification. Following conversion, the eighteen A3J·2/A-5Bs became RA-5Cs still while retaining their original BuNos. Utilizing FY 1963 funding, 43 standard RA-5Cs followed close on the heels of the eighteen original NA-269 aircraft. When the last of these rolled from the Colum-

bus Division line, it appeared that Vigilante production had come to an end. Accordingly, tooling and related hardware were placed in long-term storage and the Columbus facility shifted priorities to other products, inclUding the remanufacture of 43 A3J-l/A-5As to RA·5C standard. Attrition caused by continuing hostilities in and around Vietnam resulted in renewed Navy interest in the RA·5C during 1967. The aircraft had proven remarkably successful in its reconnaissance role (Defense Secretary McNamara once stated that the RA-5C's informationgathering capability could not be duplicated "by any other device in the Navy inventory") and no other readily available aircraft was available immediately to accom· modate the reconnaissance mission requirement. Accordingly, during 1968, in a rare occurence of reinstatement, the RA·5C was placed back in production

in order to accommodate Navy operational needs. Though initial orders called for 46 new RA-5Cs, only 36 were actually procured (the first of these flying during March 1969). The last totally new aircraft completed, BuNo. 156643, rolled from the Columbus Division's plant doors on August 10, 1970. It was delivered to the Navy on November 5. The last North American-sponsored flight of an RA-5C occurred on July 25,1974, when BuNo. 156615 departed Columbus for delivery to the fleet piloted by chief company test pilot Ed Gillespie and company airborne test engineer Dave Breese. A final delivery flight from Columbus followed on July 31 , this being accommodated by a Navy crew. In all, 156 Vigilantes were manufactured in Columbus and 140 of these were either manufactured as RA·5Cs or rebuilt to that standard. The following is a complete listing of all Vigilantes and their respective dispositions:

VIGILANTE INVENTORY It should be noted that the factory serial number indicates the order of manufacture. Some of the original A-5As (factory numbers 1 through 59) were converted to RA-5Cs; these aircraft are designated by the original A-5A number and the RA-5C conversion "C" number. BuNos. 149300 through 149305 were A-5B/YA-5C aircraft converted to RA-5Cs, and 149306 through 149317 were A-5B aircraft converted to RA-5Cs. In all, there were 156 Vigilantes made, of which 122 were RA-5Cs (79 original and 43 converted aircraft). FACTORY NUMBER DISPOSITION/LOCATION/CREW

MISCELLANEOUS DESIGN STUDIES: North American's Columbus Division continued to explore potential indigenous and foreign markets for the Vigilante and its various derivatives throughout the history of the program. The most likely customer, other than the Navy, was of course the AF, and accordingly, manyovertures to that service were made during the course of the twelve years the aircraft remained in production. Because of the Vigilante's phenomenal performance, the Air Defense Command (ADC-which later became the Aerospace Defense Command) during 1960, appeared to offer the greatest potential for a sale, and accordingly, many of North American's AF design studies were optimized to meet ADC requirements. Among the more noteworthy ADC-oriented Vigilante studies was a group proffered under the aegis of the title Retaliator. These called for the incorporation of a single Rocketdyne (North American) XLR46-NA-2 liquid-fuel rocket in the area normally occupied by weapons and/or auxiliary fuel tanks. This added pmpulsion unit was optimized to improve speed and altitude performance while permitting the aircraft to carry externally a sizable quantity of high performance air-to-air radar guided missiles. Following initial presentations during 1960 and 1962, the Retaliator was shelved temporarily while a more realistic demand for its capabilities developed. Ten years later, the ADC mission, by then referred to under the IMI acronym (Improved Manned Interceptor) was addressed with the NR-349 design which added a third J79 in the space originally allocated the linear bomb bay. Bifurcated dorsal intakes were faired into the upper surfaces of the two standard intakes and served to duct air to the additional engine. Radar guided air-to-air missiles were faired externally underneath the fuselage. Still other studies calling for the incorporation of advanced sensors and J58 turbo-ramjet engines also failed to reach fruition. Plans for Marine Corps acquisition also failed to gel. The Vigilante's innate ability to operate from short strips had made it suitable for what the Marine Corps referred to as Short Airfields for Tactical Support (SATS). This activity could be accommodated through the use of portable catapults and arresting gear. At the time of consideration, SATS units already were deployed with the Marines in the Western Pacific. Cost constraints killed the Marine Corps proposal long before hardware development was initiated. Concern remained throughout the operational career of the Vigilante over its great weight and associated high landing and takeoff speeds. Accordingly, North American, at one time, initiated discussions with noteworthy NASA aerodynamicist John Stack wherein it was concluded the company should explore the possibility of applying a variable·geometry (variable-sweep) wing to the Vigilante. This occurred during June 1959, and though wind tunnel tests at NASA's Langley, Virginia facility indicated reasonable advantages to the configuration, no full-scale hardware ever was built. It also should be mentioned that the Vigilante was offered for foreign sale to several countries, including Australia. Limited information has surfaced pertaining to the proposed foreign Vigilantes, but it appears the aircraft was proffered in a variety of configurations that included attack and reconnaissance capability. Though physically appealing and giving the impression of being quite potent, the various Vigilante proposals eventually all proved still-borne. No non-Navy Vigilantes ever flew, though at least one aircraft, BuNo. 145157, was ioaned the AF for a short term flight test program to explore its potential. Additionally, another Vigilante, BuNo. 147858, was loaned the NASA for participation in a noise pollution research program conducted at Edwards AFB, California during March/April 1963.

resulted from a new Navy training policy that was implemented at approximately the same time production Vigilantes first were becoming available for fleet introduction. Resulting from this were several special RAG (Replacement Air Group) squadrons created to support various Navy aircraft communities (Le., the Douglas A3D, the Douglas A4D, the Vought F8U, etc.). Heavy Attack (VAH) community assets thus were divided between Atlantic and Pacific Fleet organizations with VAH-3 accommodating the needs of the former and VAH·123 accommodating the needs of the latter. Because both served the A3D community, they were considered primary personnel resources for Heavy Attack Wing One (HAtWingOne) at NAS Sanford, Florida, and Commander, Fleet Air Whidbey (ComFAirWhid) at NAS Whidbey Island, Washington (assigned control over Pacific Fleet VAH units following the disestablishment of HAtWingTwo on June 30, 1959). Further to this, as per Navy standard practice, once assigned to a carrier, the VAH squadrons and detachments reported to the Commander of the embarked Carrier Air Group (CAG) for operational control. Because the Vigilante's mission underwent a drastic change from attack to reconnaissance during the course of the type's introduction into service, major changes took place in its system of squadron assignments and chain of command. As a reconnaissance platform, it was moved from heavy attack (VAH) to reconnaissance attack (RVAH) squadrons, and because the latter required only half the aircraft of the former (six vis twelve), it became possible to concentrate the RVAH community at a single shore base and consequently to limit training resources to a single RAG. NAS Sanford assumed the latter responsibilities and HAtWingOne's RAG, VAH-3 ("Heavy Three"), thus became during 1961, the primary Vigilante training squadron. The initial four operational A3J-1s were assigned to VAH-3 and formally handed over at NAS Sanford on June 16, 1961. These aircraft were used for pilot and bombardier/navigator qualification and training only. Standard curriculum for transitioning into the Vigilante consisted of the following:

OPERATIONAL SERVICE: In the middle of the turmoil surrounding its operational failings and extraordinary cost, production of the A3J·1 during the late 1950s and early 1960s continued to accelerate at Columbus. While the Congress argued with the Navy and North American over the Vigilante's bUdget and linear bomb bay problems, preparations were initiated during 1959 to make Navy transition into the type as smooth and safe as possible. Underscoring the latter was the incorporation of "contractor support" as part of the Fleet Introduction Program (FIP). Under this concept, North American provided technical training, spare parts, and maintenance assistance. Though relatively common· place during test and development, this kind of support had never previously been utilized at the FIP level. Some difficulty in integrating the Vigilante into the fleet

By May 1962, a number of pilots had been qualified in A3J-1 familiarization flights by VAH-3 instructor pilots, and the second two classes of pilots and bombardier/ navigators from VAH-7 were undergoing training. VAH·7, in fact, became the first operational unit to receive the type when it began transitioning ftom the Douglas A3D-2 to the A3J-1 during the summer of 1961, utilizing aircraft assigned to VAH·3. The first of VAH-7's allotment of 12 A3J-1 s began to arrive at NAS Sanford on January 25, 1962, deploying for a NATO 6th Fleet exercise in the Eastern Atlantic and Mediterranean the following August aboard the new USS Enterprise (CVAN-65) for the new attack aircraft's first cruise.' This initial cruise proved somewhat abbreviated, due in part to the fall-out resulting from the Cuban Missile Crisis, and following a little over two months at sea, VAH·7 and the USS Enterprise returned to Florida on October 11. Some three months later, on February 6, VAH-7 again departed aboard the USS Enterprise to again join the 6th Fleet in the Mediterranean. This cruise was of full duration, ending some seven months after it began upon the arrival of the USS Independence (CVA-62) and VAH-1 as part of the 7th Fleet. 'This also was the operational debut of the USS Enterprise.

VAH-1 had, in fact, begun receiving its first A3J-1s on Janaury 22,1963. By the time of the Vigifante's arrival, the September 18, 1962, introduction of the new DoD unified nomenclature system had taken place and the type now was formally referred to as the A-5A. VAH-1, by the time of its first deployment with its new aircraft, had gone through the still rapidly developing Vigifante training program being accommodated by VAH-3. With the intention of replacing VAH-7 (aboard the USS Enterprise) VAH-1 departed for the Mediterranean aboard the USS Independence on its one and only A-5A cruise on August 6, 1963, under the aegis of the 7th Fleet. The cruise lasted seven months, at the end of which time the USS Enterprise with VAH-7 aboard arrived in the Mediterranean as a replacement. VAH-7's cruise aboard the USS Enterprise in the Mediterranean began during late February 1964 and continued through July 29 when the USS Forrestal on that date formally replaced it. Somewhat surprising, though already having been at sea for some five months, the USS Enterprise did not immediately head for its home port. Instead, accompanied by the cruiser USS Long Beach (CGN-9) and the frigate USS Bainbridge (DLG N-25), under the auspices of "Operation Sea Orbit" and as the spearhead for Task Force One (TF1), it departed the Mediterranean on a southerly course that proved to be the first leg of a round-the-world cruise. Utilized as a mission to prove the Navy's ability to conduct prolonged operations on a global basis, "Operation Sea Orbit" ended on October 3, 1964, when the ships arrived at Norfolk, Virginia. "Operation Sea Orbit" and the preceding five months spent in the Mediterranean as part of the 6th Fleet proved to be the swansong cruise for the A-5A. This firstgeneration Vigilante finally had proved simply too cumbersome and unproductive for the Navy to support. Coupled with continuing linear bomb bay and associated bombing system difficulties and a decision to reorient the aircraft's mission responsibilities and upgrade extant aircraft to the improved RA-5C configuration, A-5As quickly were relegated to training roles and removed from the active inventory as heavy attack aircraft. At a later date, all surviving examples were returned to Columbus for conversion to RA-5C standard. In the interim, another nomenclature change had been made to the Navy's designation system, this one, on December 20, 1963, resulting in Carrier Air Groups (CVGs) being retitled Carrier Air Wings (CVWs). Fleet designators thus became CVWs in concert with the new reference acronyms. Also during this period, the two extant operational A-5Bs, BuNos. 149300 and 149302, joined VAH-3 at Sanford and there were utilized temporarily as Vigifante trainers. As more and more RA-5Cs 12

entered the inventory, the two A-5Bs became redundant and eventually were returned also to Columbus for upgrading and retrofit to RA-5C standard. With the successful completion of initial flight and sensor systems trials during early 1963, the delivery of the first RA-5Cs to VAH-3 was initiated during January 1964. These aircraft, which had been turned over to the Navy on June 27, 1963, initially were used as introductory trainers and preceded actual fleet introduction of the type by several months. Fleet introduction finally got underway during mid-1964, when VAH-5 received its initial RA-5C allotment at NAS Sanford, Florida. These first aircraft joined a small group of well-worn A-5As being utilized as interim trainers. As more RA-5Cs joined the squadron, the A-5As were phased out so that by the middle of 1964, none remained in the unit. Effective during the spring of 1964, the few extant VAHdesignated units were redesignated RVAH- as each squadron's transition into the RA-5C neared completion. The new designation more accurately reflected the new aircraft's specified mission objectives. Associated with the new squadron identifiers was a decision to change the title of the unit's "parent" organization while shore based. Accordingly, during August 1964, NAS Sanford, Florida, as part of ComNavAirLant's Heavy Attack Wing One, had its name changed to Reconnaissance Attack Wing One (RAtWingOne). All units had taken delivery of the Vigilante at NAS Sanford, but shortly after delivery of the last aircraft from this facility, a decision calling for the movement of the entire Vigifante community to NAS Albany, Georgia was inacted. The official date of change was May 1, 1968, though with several squadrons at sea, actual completion of the move was some time in taking place. Six years later, during 1974, the community moved again, this time to NAS Key West, Florida. It would remain at Key West for the rest of its service career. By the early summer of 1964, RVAH-5 had completed transition into the RA-5C and was preparing for its first officiai tour of duty. Assigned to CVW-9 aboard the USS Ranger (CVA-61), the unit found itself involved in training exercises off the coast of Hawaii shortly after the infamous Tonkin Gulf debacle of August 2. Accordingly, it became the first Vigifante squadron to participate in WestPac operations when the USS Ranger became part of the U.S. build-up resulting from the late summer's events. The gradual increase in U.S. involvement in Vietnam curtailed a strong showing of RVAH-5's capabilities during this first operational deployment. Because of the scarcity of RA-5C assets, the sensitivity of select RA-5C sensors, and inexperience with the Vigifante as a reconnaissance platform, the Navy's Vought RF-8A assets

were tasked with covering the high threat regions of N. Vietnam while Vigifante assets were assigned the less threatening S. Vietnam arena. This scenario would be short-lived, however, as following the return of the RVAH-5 to the U.S. during May 1965, four more Vigifante squadrons were sent into the combat zone. The first of these was RVAH-1, assigned the USS Independence (CVA-62) as part of CVW-7 and entering combat during the summer of 1965. Two more Vigifante squadrons followed during October, these being RVAH-13 aboard the USS Kitty Hawk (CVA-63) as part of CVW-11 which departed on the 19th, and RVAH-7 aboard the USS Enterprise (CVAN-65) as part of CVW-9 which departed on the 26th. RVAH-9 also departed for WestPac near the end of the year, as part of the USS Ranger's (CVA-61) complement under the aegis of CVW-14. In response to a series of bombing anomalies quickly attributed to inaccurate maps, one of the first major tasks handed the Vigifante units operating in Vietnam was the generation of optical imagery of the entire Vietnamese plat. This was accomplished without extraordinary difficulty over a period of some two weeks, quickly building confidence in both the aircraft and its systems and correcting inaccuracies in the original references that had led to bombing errors approaching, in some instances, 4 miles. The RA-5C over Vietnam incurred the highest loss rate of any Navy aircraft of the war. Though the RA-5C's mission of pre- and post-strike reconnaissance was simple in principal, it was extremely dangerous in execution. The basic mission objective was to obtain photographic imagery of a target or group of targets both before and after a strike mission. Gathering imagery of a target prior to a strike proved only modestly dangerous due to the element of surprise enjoyed by the overflying aircraft. But N. Vietnamese defenders learned very quickly to expect a post-strike fly-over as well-and invariably had antiaircraft weaponry at ready by the time this segment of a mission took place. Such activity eventually resulted in the loss of at least 23 RA-5Cs in Vietnam, including 18 downed aircraft directly attributable to combat activity. Anti-aircraft artillery was credited with 11 of the 23 losses, and 2 more were written-off following lethal hits by SA-2 Guideline surface-to-air anti-aircraft missiles. Additionally, ground defenses, most likely in the form of SA-2s, are known to have led to the loss of 2 additional aircraft, and at least 1 RA-5C was shot down by an Atoll launched from a MiG-21. In addition, there were 5 operational RA-5C losses (ramp strikes, etc.) inclUding 2 that remain potentially combat-related. The Vigifante's reputation for ramp strikes was well

deserved. The aircraft was difficult to land on a carrier due to its size, its mass, and its high landing speed. Pilots often voiced concerns about the difficulty of carrier operations during marginal weather conditions and mechanical emergencies. It was well known that the most stressful part of a mission for a Vigilante back-seater was the final approach to landing aboard a carrier. Some personal insight into the plight of the average RA-5C pilot operating in Vietnam is provided by the following quoted from a lelter sent to The Hook editor, Robert Lawson by Art Skelly: "Of the 260 combat flights I flew in the Vi9i1ante, the most unusual had to be with RVAH-6 during 1966 aboard the USS Constellation. One dark, overcast Sunday morning, I photographed an oil storage area that had been hit the previous night by A-6s. On our way out of the target area over downtown Haiphong, we took some severe AAA, automatic weapons fire, and SAMs. Tracers were criss-crossing over the canopy and the F-4 escort pilot was going crazy calling out flak. I decided we had had enough so I pulled up into a nearby thunderstorm and we immediately encountered rain, hail, and lightning. I was on instruments, 4,000 ft. altitude, 600 knots, wings level and still dodging tracers. The attitude gyro just didn't look quite right, but that was the least of my worries, then. A few seconds later I broke out on the other side and we were inverted. The F-4 was right in position, inverted tool The guys in the ready room threatened to mount a Brownie on top of my hardhat for future maneuvers."

During the course of the Vigilante's Vietnam career, which spanned from August 1964 to the ceasefire in 1973, squadrons assigned the aircraft completed 31 combat zone deployments. RVAH-5 and RVAH-610gged five deployments to the war zone, RVAH-1, RVAH-7, RVAH-~ 1, and RVAH-13 logged four deployments, RVAH-12 logged three deployments, and RVAH-910gged two. Two Vigilante squadrons never were assigned to Vietnam. RVAH-3, in its capacity as a training squadron, was never deployed in an operational capacity and remained stateside throughout this period, and RVAH-14 was a permanenttenant of the 6th Fleet in the Mediterranean. This unit was not the first RA-5C squadron to serve in the Mediterranean, however, as RVAH-9 had operated there from the USS Saratoga (CVA-60) as part of CVW-3 from December 1964 to June 1965. By the time of the RA-5C's final, post-Vietnam war tour to WestPac on the USS Ranger during September 1979, the type had completed a total of 73 deployments throughout the world. Of these, 41 were to WestPac (both during and after the war) and 32 were to the Mediterranean. Four additional cruises, as mentioned earlier, were completed by the A-5A. The last carrier-arrested landing of an RA-5C occurred when BuNo. 156615 of RVAH-7, crewed by LCdr. Habel

and Lt. Parr, trapped on the USS Ranger on August 17, 1979. The last RA-5C catapult takeoff from a carrier occurred on September 21, 1979 when BuNo. 156608 of RVAH-7, crewed by Cdr. Myers and LCdr. McManamon departed the USS Ranger for NAS Key West. This was followed by the last RA-5C field arrested landing which took place on November 14,1979, when BuNo. 156608 of RVAH-7, crewed by Lt. Little and LCdr. McCray, was trapped at NAS Key West. The last Vigilante flight occurred shortly afterwards when, on November 20, BuNo. ~56608 of RVAH-7, crewed by Lt. Westmoreland and LCdr. Plunkett (CRAW-1), departed NAS Key West for Davis-Monthan AFB. All that now remained of the original Vigilante community was several aircraft temporarily stored "in situ" at NAS Key West and a single aircraft saved for use as a gate guardian. As a last act to permanenliy end the operational history of the magnificent Vigilante, the formal disestablishment of Reconnaissance Attack Wing One was consummated on January 7, 1980. Thirty-six Vigilantes eventually found their way to Davis-Monthan AFB where they were placed in storage. Of this number, eight eventually were transferred to the New Mexico Institute of Mining and Technology storage area at Socorro, New Mexico, there to eventually be used as targets; five were transferred to the Naval Weapons Center at China Lake, California, there also to be used as targets (at one time, droning select Vigilantes was discussed, but this idea never reached fruition); one was donated to the Pima Air Museum at Tucson, Arizona (next to Davis-Monthan AFB) and there placed on display as a museum artifact, and the remainder were assigned to long-term storage. It is interesting to note that scarcity of Vigilante assets during the course of the type's operational history played a key role in dictating the number of aircraft assigned each squadron. The nine deployable units initially were assigned a complement of six aircraft each. This figure remained fixed until approximately 1971 when attrition finally eroded the buffer that had resulted from the 36 follow-on new-build production aircraft. After that date, the per unit aircraft figure stabilized temporarily at 4 to 5, but by 1973, had dropped to just 3 aircraft. This figure remained constant throughout the rest of the Vigilante's operational career, though only because of a steady decline in the number of operational Vigilante squadrons. The beginning of Vigilante phase-out had been underscored by the rapidly escalating difficulties resulting from these asset shortages. From 1974 through 1979, these shortages had become so acute the trading of aircraft between squadrons in order to maintain minimal reconnaissance capability had become commonplace. Normal attrition also had continued to take its toll, forcing units

to operate fewer and fewer aircraft while attempting to meet on-going and ever-increasing assignment loads. A vicious cycle now began to develop wherein remaining aircraft, though used somewhat sparingly, were forced to log more hours in order to accommodate on-going fleet requirements. In turn, this placed a heavy burden on airframes and maintenance needs while consuming fatigue life and reducing spare parts inventories. With prOduction permanently ended and maintenance liabilities rapidly escalating, the Vigilante's future as an operational Navy reconnaissance platform was decidedly limited. RVAH-14 became the first RA-5C unit to be disestablished when on May 1, 1974, its remaining aircraft were assigned to the surviving Vigilante community members. VIGILANTE SQUADRONS: VAH-1/RVAH-1 Srook/n' Tigers-This squadron began transitioning from the Douglas A3D-11-2 and Lockheed P2V-3BI-5 to the A3J-1 during September 1962. The following month the A3J-1 was redesignated A-5A. VAH-1 became the second fleet squadron to receive the Vigilante when it accepted its first aircraft on January 22,1963. Following one deployment aboard the USS Independence (CVA-62) with the A-5A, the unit began transitioning into the RA-5C during early 1964. Redesignated RVAH-1 on September 1, 1964, it made its first deployment as a reconnaissance unit during May 1965. This also was the USS Independence's and RVAH-1 's first combat deployment. Two more homeport changes eventually were made, the first to NAS Albany on July 18, 1968, and the last to NAS Key West on August 2,1974. The unit was decommissioned on January 19, 1979.

RA-SC, BuNo. IS0836, equipped with night photography flasher pods under its wings, being hooked on the USS "America's" (CVA-66) port bow catapult prior to launch.

RA-5C on December 10,1963 and was redesignated as RVAH-3 on July 1, 1964. During its service career its homeport was moved from NAS Sanford to NAS Albany on May 1, 1968, and from there to NAS Key West on January 15,1974. After serving as the Vigilante community RAG throughout its career it was disestablished on August 17, 1979. RVAH-3 incorporated the Fleet Photographic Laboratory as a Special Class Photo Lab. From 100,000 to 120,000 prints a year were produced by this facility before its disbandment. RVAH-3 also served as the starting point for what eventually became known as the Naval Intelligence Processing System (NIPS). As part of the original North American developed Integrated Air In· telligence System (IAIS), the Surface Sub-System (SSS), later designated the Integrated Operational Intelligence Center (IOIC), was installed aboard several attack car· riers to process and exploit the photographic and electronic "take" of the RA-5C. Air intelligence officers, photographic interpreters and photographers mates, data processors, aviation electronic technicians, and radarmen (later replaced with cryptologic technicians) all were trained in this facility to provide intelligence analysis and support. When aboard carriers, it was referred to as the Carrier Intelligence Center (CVIC). When referred to in conjunction wit the RA-5C, it was known as the Integrated Operational Intelligence System (lOIS). Following an upgrade and capability expansion program, the IOIC was known as the Naval Intelligence Processing System Training Facility NIPSTRAFAC, on January 16, 1974, was moved to NAS Key West. In a typical application of the lOIS concept, a single RA-5C making a reconnaissance pass at supersonic speed at low or high altitude, would gather continuous full spectrum passive electronic countermeasures, infrared, side-looking airborne radar, and multiple serial frame and panoramic camera data that was geographically position-and-time correlated by means of a matrix block recorded on each sensor's media. This matrix was the key to the correlation and analysis function of the CVIC whereby information gathered could be rapidly and accurately recalled for detailed analysis. Targets detected by one media or the other could be isolated for further consideration and evaluation by immediate cross· referencing all other data acquired at that time. This permitted the command structure complete and highly ac· curate information of a given area of interest.

VAH-5/RVAH·5 Savage Sons-This unit converted from the Douglas A-3B to the RA-5C during mid-1963. In the interim, it operated a few A-5As and utilized them as conversion trainers. On May 1, 1964, it was reo designated RVAH-5 and by then had converted complete· Iy to RA-5Cs, becoming the first squadron to deploy operationally with this Vigilante version when they took it into combat over Vietnam while aboard the USS Ranger (CVA-61). Its homeport was moved from NAS Sanford to NAS Albany on May 1, 1968, and then to NAS Key West on January 16, 1974. The unit was disestablished on September 30, 1977. SAVAGE SONS CRUISES Carrier

RVAH·6 Fleurs-This unit transitioned from the Douglas A-3B to the RA-5C. Its first aircraft arrived at NAS Sanford on September 16, 1965, seven days before a for· mal redesignation to RVAH-6. After several combat cruises it survived the devastating fire aboard the USS Enterprise (CVAN-65) during January 1969 and as a result it was based temporarily at NAS Barbers Point until the carrier was repaired at Pearl Harbor. By March, the unit was again at sea and during April, was ordered into the Sea of Japan in connection with the downing of a Navy Lockheed EC-121 M by North Korean fighters. At the time, RVAH-6 and the USS Enterprise became part of the largest task force assembled since WWII. The unit's homeport eventually was moved from NAS San· ford to NAS Albany on December 1, 1967, and from there to NAS Key West during 1974. It was disestablished on October 20, 1978.

VAH·7/RVAH-7 Peacemakers of the Fleet-This unit transitioned from the Douglas A3D-2 to the A3J-1 during August 1961, though its first Vigilantes did not arrive until January 25, 1962. In the interim, a new insignia was adopted along with the Peacemakers nickname. The unit's first deployment with the Vigilante began during August 1962 when it accompanied the USS Enterprise (CVAN-65) to the Mediterranean. Transition into the RA-5C began during August 1964, and on December 1, 1964, it was redesignated RVAH-7. The squadron's first WestPac and combat deployment occurred during October 1965 with the USS Enterprise and it flew its first combat mission on December 2. The unit's final WestPac tour, conducted between February and September 1979, also became the last Vigilante operational cruise. The unit's homeport was moved from NAS Sanford to NAS Albany on May 1, 1968, and then to NAS Key West during July 1974. It was disestablished on September 28,1979.

Its homeport was moved from NAS Sanford to NAS Albany on May 1, 1968, and from there to NAS Key West during January 1974. It was disestablished on July 2, 1979. RVAH-12 during the course of its Vigilante history was picked to serve as the short-term host unit for a little known, and at the time, highly sensitive project known as Snare. This involved the installation of an articulated, infrared spectrum sensor on the top side of two aircraft, BuNos. 148933 and 151727, just ahead of their respec· tive vertical tail surfaces. The Xerox·manufactured Snare was hydraulically slewable and controlled from the back seat of the aircraft. A viewfinder for aiming was provided. All of the system's electronics were contained in the basic module, which protruded approximately ten inches above the topside of the aircraft. Data from the unit was collected on a 16 channel analogue tape recorder for later evaluation. Missions to obtain laser emitter and other related data from special Soviet Badger, Bear, and Bison long range bombers flying fleet observation missions from Russian soil were conducted from the USS Independence for a short period during the unit's 1971/1972 Mediterranean cruise.

The unit later became the first RVAH squadron to be awarded the Presidential Unit Citation when the USS Kitty Hawk and CVW-11 received the award for a previous cruise. During a 1971 combat cruise, RVAH-11 provided the first tactical reconnaissance photographs of Haiphong harbor since the bombing halt of 1968. The unit's homeport was moved from NAS Sanford to NAS Albany on December 1, 1967 (though the new quarters were not occupied until June 1968), and from there to NAS Key West during 1974.

The disestablishment of Reconnaissance Attack Wing One remains an event unique in the annals of U.S. Naval aviation history. Never before had an entire community been phased out of operation so completely, and without a replacement. The gap left by the demise of the RA-5C continues to this very day. Though reconnaissance systems are available to the Navy, with the exception of the few extant Marine Corps RF-4Bs, virtually all are parasitic units with limited capability-compromised by their podded enclosures or thei~ "quick change" requirement.

set as an integral part of the radar equipped inertial navigation system (REINS). This unit (developed from the autonavigator system resulting from North American's work on the Navaho missile program) was composed of an inertial autonavigator, a navigational computer, a North American NASAR bombing computer, tie-in equipment, a general-purpose radar set, and controls and indicators for operation of the entire system. The AN/AS8-12's basic purpose was to provide navigation and aircraft positioning. In addition, a closed-circuit television set was pro-

vided as a daylight navigation aid. All-environment capability was made possible by the system's ability to provide accurate navigation with unlimited range, position read-outs in latitude and longitude, ground-mapping radar operation, and a steering signal presented on the pilot's all-attitude indicator (AAI) and available to the lateral axis of the AFCS. AN/AS8-12 capabilities inciuded: (1) Multiple target or destination capability through preset or in-flight set-in of any five positions; (2) allenvironment position monitoring using general-purpose radar equipment; (3) highly accurate visual identification and navigation through a closed-circuit television sight; and (4) digital and analog information required for operation of reconnaissance systems. The inertial autonavigator subsystem consisted of a gyro-stabilized platform on which were mounted two velocity meters. Part of this sUbsystem was a digital navigation computer called Verdan (Versatile Digital Analyzer). Verdan was a digital computer with a generalpurpose computing section and a differential analyzer which shared a common, rotary, magnetic memory disk. Verdan continuously calculated aircraft position with respect to the earth local level plane and could calculate range and bearing to selected checkpoints or targets. The General Dynamics Electronics radar, integrated into the AN/AS8-12 was a general-purpose unit operating in the J-7 band at 60 kw peak power in a narrow, duallobe pattern. The radar provided conventional and expanded ground-mapping and contour-mapping in a + or - 45° sector scan, depressed-center PPDI-type display. The normal ground-mapping mode provided all-weather navigation assistance and target location with peak performance optimized at 60 n. miles range at 60,000 ft. The radar antenna was a dual-surface, paraboloidal reflector containing a flexible mylar diaphragm. The latter provided a changeable basic antenna pattern allowing either conventional ground-mapping or "pencil" beam pattern options. A closed-circuit television sight was installed as part of the AN/AS8-12. The scanner sight was composed of a vidicon tube and an optical prism unit which, when selected, would present a view of the area on the RAN's radar-television indicator and pilot's projected display indicator (PPDI). The latter, representing the first Heads Up Display (HUD) ever installed in an operational aircraft, provided data (via radar displays) and terrain avoidance and normal ground or contour map, altitude, steering, and weapon delivery command information, all projected on a diachroic mirrored surface that sat, like a conventional HUD, on top of the pilot's instrument panel. The scanner assembly was mounted in a small dome under the nose, aft of the radome. The optics for this unit could be slewed to 45° left or right of the aircraft centerline and vertically downward to 55°. A fixed aft-vieWing position also was possible and three beam angles were available. Two slightly different ejection seat types eventually found their way into the Vigilante. Initial prototype and production A-5As were equipped with North American HS-1 seats which permitted escape at speeds as low as 100 knots. late A-5As, the A-58s, and the RA-5Cs all were equipped with North American HS-1A seats capable of zero-zero emergency egress. In either the HS-1 or the HS-1A, the seat bucket was electrically adjustable through a vertical range of 5 in. (the headrest, however, remained stationary). The original seat was equipped with an N8-7E personnel parachute requiring the use of a standard integrated harness garmet; later seats were equipped with the N8-7E or NES-15A parachutes. With the original seat, ejection was initiated by pUlling the face curtain handle forward and down sharply to full travel, or by turning (unlocking) and pulling either alter· nate ejection knob. Seat ejection thrust was provided by a single unit catapUlt rocket. This provided sufficient force to propel the seat approximately 125 ft. above the aircraft flight path at average cruising speeds. A 52 in. stabilizing drogue parachute then deployed from the headrest. An automatic seat/man separation system, following seat stabilization and descent to below 13,000 ft., would actuate and kick the seat away at apprOXimately 2 secs. This would be followed by parachute and survival kit deployment and descent. The cockpits were air conditioned and pressurized. The air conditioning system provided the following functions: cockpit and pressure suit conditioning; cockpit and pressure suit pressurization; cockpit cooling and pressurization (unpressurized to 8,000 ft.; constant 8,000 ft. level pressure from 8,000 ft. to approx. 23,400 ft.; constant 5.0-psi differential pressure at all altitudes above approx. 23,400 ft. MSl); anti-g suit operation; windshield and canopy defrosting and windshield anti-icing; engine anti-icing (it should be noted that there were no provisions for inflight structural anti-icing and it was not recom-

mended the Vigilante be flown in known icing conditions); pneumatic system supply; and hydraulic reservoir pressurization. In addition, the air conditioning system also provided pressurized air for the canopy seals, air data computer, liquid oxygen bay, ECM waveguide, radar, inertial autonavigator platform, aircraft fuel supply system, and hydraulic reservoirs as well as supercharging air to the pneumatic system air compressor. Air for this system came from the final stage of each engine compressor where taps at three points bled hot, high-pressure air and routed it to primary heat exchangers on each side of the aircraft. There it was cooled to approximately 300°F. by ram air from the engine intake ducts. Two independent oxygen systems were installed. The normal breathing oxygen supply, good for 8 hrs., was provided by a liquid oxygen conversion system. The original A-SA windscreen design was produced as a multi-laminate of tempered glass and silicone in layers. At the time of its introduction, this unit was claimed by its maufacturer, Libby-Owens-Ford, to be the largest onepiece curved, laminated aircraft glass made up to that time. At an early stage in the production program, this unit was replaced with a stretched acrylic windscreen that was substantially less expensive and decidedly easier to manufacture. The pilot's and systems operator's cockpits were provided with separate, jettisonable, clamshell-type canopies. The pilot's canopy was of conventional design. The systems operator's canopy was primarily of metal construction with a single, small window on each side, this to restrict the amount of light in the cockpit in consideration of the need to monitor radar and television equipment. A sliding shade arrangement was installed for both windows in the systems operator's/RAN's canopy for darkening the cockpit. 80th canopies were opened and closed by pneumatic cylinders which were controlled by pneumatic toggle vavles installed in each cockpit. Power for canopy operation was supplied by the pneumatic compressor system and an air storage bottle with 3,000 psi pressure reduced to 450 psi. An emergency air bottle for each canopy permitted emergency egress_ Fully opened, the canopy angle was 33°. Normal opening or closing time was approximate 5 sees. Fuselage: The 14.47 to 1 fineness ratio fuselage was of conventional all-metal semi-monocoque construction. Primary materials were aluminum and steel, with titanium in the engine bay and high load carry-through areas. The fuselage was broken into three major components consisting of the forward fuselage, the intermediate fuselage, and the aft fuselage. The engine nacelles were tied into the linear bomb bay via two main bulkheads. The forward bulkhead also served as a major carry-through structure for the wing attachment points. The aft bulkhead, of steel, absorbed wing and concentrated landing loads from the landing gear. A wing brace also transmitted side loads from the wing to the aft steel bulkhead. To permit access to the radar compartment and to facilitate handling, the nose radome could be opened and rotated upward and aft through operation of an electrical actuator. With both the vertical tail and the radome folded, the RA-5C's over-all length was reduced from 76.55 ft. to 65.57 ft. Wings: The wings were developed from earlier North American design philosophies that had given birth to the wings for the FJ-4 and F-100 series fighters. The wing skins were integrally machined from large slabs of Alcoa 2020-T6 aluminum-lithium alloy. This material offered greater strength than conventional aluminum alloys while providing great elasticity and reduced density (and thus lower weight). The main structural boxes of the inboard and outboard wing panels were similar in that they both had milled upper and lower skins, redistribution ribs, and front and rear spars. The main differences between the inboard and outboard panels were: (t) the inboard wing had intermediate spars to stiffen the skins whiie integral stringers were used on the outboard wing for this purpose, (2) the inboard wing was an integral fuel cell while the outboard panel was not. The wing sweep angle was 27.5° at quarter-chord and the thickness-chord ratio was 3.5%. The wings could be power folded by the NO.2 hydraulic system. A hydraulic lock valve was provided in the wing fold line to prevent inadvertent wing spreading in the event of hydraulic pressure loss during wing folding. Positive hydraulic sequencing actuated lockpins upon completion of the wing spread cycle. Manually operated locks, actuated from the cockpit, secured the lockpins in position. The wings could be cycled independently, if desired. When the wings were folded, the span was reduced to 42 ft. 4 in. (A-SA). lateral control was provided by a spoiler-deflector system. Control was through master actuators and mechanical linkages, which, in turn operated full-powered hyd raulic actuators. The spoiler-
deflectors on the upper surfaces. The inverted spoilers opened a maximum of 70° and the outboard deflectors opened a maximum of 39°. The spoilers and deflectors were mechanically interconnected so that hydraUlically powered movement of the spoilers resulted in movement of the deflectors. During rolling maneuvers, the inverted spoilers and deflectors on the outside wing induced drag, offsetting the yaw effect of the mid and inboard spoilers on the inside wing. A series of override bungees were installed in the mechanical linkage to the spoiler actuators, consisting of one bungee for each inverted spoiler and one for each set of inboard and mid spoilers. These bungees allowed continuous operation of the lateral system in the event one set of actuators should fail. The spoiler-deflectors also could be used as speed brakes. Ttie flaps were equipped with a system permitting pllcn trim change via flap extension or retraction. An interconnect unit mechanically repositioned the pitch augmentation actuator, thus moving the horizontal stabilators to a new trimmed position. Full span leading edge flaps were installed on each Wing. These consisted of three hydraulically powered and mechanically controlled sections. The outboard section operated on linkage separate from the inboard sections, and had an actual maximum extension of 38.5° on the A-SA and 50° on the RA-5C, while the mid-and inboard sections extended to a maximum of 25.5° on the A-SA and 28.5° on the RA-5C. Activation of the wing flaps automatically positioned the leading edge flaps through a series of jackscrews driven by motors powered by the NO.2 hydraulic system. At less than transonic speeds, the leading edge flaps normally were lowered to 5° on the outboard sections and 3° on the inboard sections for best cruise angle. All Vigilantes were equipped with boundary layer control systems (8lC). However, the A-SA had 8lC on its trailing edge flaps, only, whereas the A-58 and RA-5C had 8lC only on their leading edge flaps. 8lC decreased the airspeed and angle-of-attack required for approach and landing, and also minimized the amount of aircraft rotation required for takeoff. A 8lC valve, installed in the compressor bleed line from each engine, directed highvelocity air over the tanding flaps, beginning when the flaps left the fully retracted position. Flow began as the flap droop approached the 25° position and reached maximum when the flaps were extended to approximately 40°; the valves were full open at 50°. Tall Surfaces: longitudinal and directional control were provided by single-piece slab-type horizontal stabilators and a single-piece, slab-type vertical tail surface, respectively. All surfaces were hydraUlically powered and irreversible. Control of the longitudinal system was through master actuators and mechanical linkages, which, in turn, operated full-powered hydraulic surface actuators. The directional control system was a direct, mechanically controlled and hydraUlically powered system. 80th the longitudinal and directional systems were augmented for optimum control characteristics at various altitudes and airspeeds. The horizontal surfaces were attached to spindle fittings on the fuselage, below the vertical fin. Each surface had a travel range of 15° leading edge up and 18° leading edge down. Pitch trim involved small, symmetrical movements of both horizontal tails. Changes in lateral (roll) trim were accomplished by differential deflection of the stabiliators. Even in consideration of this capability, the horizontal tail surfaces could not be used for roll control. The vertical tail was an all-moving, siab-type unit. Total surface travel was 16° (8° either side of center)_ Travel was regUlated by a ratio-changer controlled by the position of the wing flaps. Travel varied linearly from 2° left or right (with flaps up) to 8° left or right (with flaps down 25° or more). The vertical tail surface could be folded at an angled hinge line located at approximately mid-height. Power folding was accomplished by No. 2 hydraulic system pressure. Manual folding also was permissible. Positive hydraulic sequencing actuated lockpins upon completion of the unfold cycle. When the vertical fin was folded, height of the aircraft was reduced from 19 ft. 4 in. to 15 ft. 6 in. Flight Control Systems: The flight control systems were hydraulically powered and irreversible. The longitudinal and lateral systems were electrically controlled, hydraulically operated systems with a stand-by mechanical control system. The directional system was mechanically controlled and hydraulically actuated. The longitudinal and lateral systems used master actuators which were capable of accepting either mechanical inputs from the control stick or electrical inputs from the electrical control system. The master actuators mechanically positioned the control valves on the horizontal stabilator and spoiler surface actuators. Movement of the control pedals was transmitted directly to the vertical tail surface actuator. Electric trim actuators (controlled with conventional trim switches) were used for roll, yaw, and alternate pitch trim. Normal pitch trim was provided by using the same electric trim actuator and controlling it electronically using an input for the pitch trim synchro on the pilot's stick grip. Electronic augmentation systems were provided for both directional and longitudinal stability. Augmentation was accomplished by using inputs from

It utilized inputs from the air data computer, flight reference set, the AN/ASN-26, and the AN/ASB-12, and provided outputs to the longitudinal and lateral control systems.

hoses. It was operated by an emergency brake handle in the front cockpit.

Landing Gear: The fully retractable tricycle ianding gear was electrically controlled and hydraulically ac- . tuated. All three gear rotated forward during the retraction process with the main gear rotating 900 before locking into their respective wells. Normal retraction sequences took about 7 to 9 seconds. In the event of a hydraulic system failure, the forward retraction feature allowed the gear to be extended by graVity and air loads if the pilot pulled the emergency gear extension handle. The wheel well doors were electrically sequenced to open whenever the gear were in their unlocked position. The strut and trunion fairing doors were mechanically linked to, and retracted by, the landing gear struts. The main gear were each equipped with a single 36 x 11, Type VII, 24-ply tire inflated to 120 psi (minimum)

and 225 psi (maximum) for shore use and 250 psi for shipboard operations, and independent disc brakes. The nose gear was equipped with a single 26 x 6.6, Type VII, 16-ply tire inflated to 150 psi for shore use and 325 psi for shipboard operations.

Nose wheel steering to 75° (+ or - 5°) either side of the aircraft centerline was available through the directional control pedals when the pilot depressed the steerlterrain button. When the button was not depressed, the nose wheel was in the damping, swiveling configuration which allowed 360° swiveling for ground handling purposes and unlimited steering deflection through differential braking. When being towed, a Navy universal tow bar (NT-2 Model 3 or similar) was required. The brake system consisted of two independent hydraulic systems: the normal brake system and the emergency brake system. These were completely separate down to the shuttle valve at each main gear wheel. The normai system consisted of a power brake

The Vigilante was equipped with an arresting gear for carrier operations. The arresting hook was located on the aft lower fuselage and was hinged adjacent to the root of the horizontal stabilator leading edges. The V-shaped assembly was faired into the fuselage by mechanically operated trunion, hook point doors, and beam fairing doors. The hook was retracted by No. 2 hydraulic pressure and extended by a piston-type air hydraulic accumulator. Hook point doors were installed to cover the

hook point when the arresting gear was retracted. These doors were opened and closed mechanically by the hook during the cycle. An air-oil hook bumper unit prevented the hook from bouncing into the access well during an arrested landing and retracted before the hook was retracted. The hook extended to 550 from the vertical. HydrauliclPneumatic Systems: During the early stages of Vigilante design, North American envisaged using compressed nitrogen rather than hydraulic fluid for the aircraft's power requirements. As this proved impractical, a more conventional hydraUlic system was utilized

emergecny flap extension system. Prior to flight, the pneumatic system bottles were precharged to 3,200 psi. During flight. a hydraulic motor-driven air compressor

maintained the bottles at 3,000 psi. The compressor was powered by the NO.2 hydraulic system. A Garrett AiResearch ram-air turbine (RAT) was installed just ahead of the left main gear well. It extended automatically or upon pilot demand. It was capable of providing both minimal hydraulic power and minimal elec-

trical power (via hydraulic power) during emergency situations.

Electrical System: The A-5A electrical power source was a 400-cycle, constant-frequency, alternating-current system supplying three-phase power (A, B, C rotation) at 115 volts per phase. Across any two phases, power measured 200 volts. Normal AC power was provided by two engine-driven brushless generators. Essential AC and DC bus power could be provided by an emergency power unit driven by the RAT. The A-5A had two 30 kva AC generators with one being driven by a constant-speed drive on each engine. pro-

viding a total system capacity of 60 kva. The RA-5C had two 42 kva AC generators providing a total system capacity of 84 kva. The generators were cooled by passing oil from the engine oil tank through the frame and shaft of each unit.

The AC power distribution system was composed of two independent systems. The NO.1 system normally was energized by the left-hand generator and consisted of the NO.1 primary bus and monitored buses. The NO.2 system normally was fed from the right-hand generator and consisted of the No. 2 primary and essential buses. For ground operation of all buses, external AC electrical power was required. Power access was on the left side

valve with an integral manual master cylinder, an aux-

of 2,800 to 3,250 psi. The reservoirs were pressu rized to provide adequate fiuid supply to the engine-driven pumps under all conditions. The NO.1 system provided hydraulic power to all basic flight control actuators, the yaw augmentation system, and the leading edge flaps. The No. 2 system provided power to all basic flight control system actuators, the leading edge flaps, and all other hydraUlically operated systems and components.

iliary accumulator, and necessary lines and hoses. The power brake valves, one for each wheel, provided differential pressure at the wheel in proportion to the degree the pedals were depressed. Hydraulic pressure from the NO.2 hydraUlic system was metered from the system to each brake unit. The normal system was capable of up

of the fuselage, forward of the main landing gear. DC power was obtained by utilizing two 200-ampere DC converters (transformer-rectifiers), a primary and an alternate, to provide 28 volts DC to various systems. The DC power distribution system was composed of the primary bus and the essential bus. Lighting: Interior lighting consisted of: Pilot: right and left console red floodlights; right and left console white high-aititude lights; console refractor panels red lights (indirect); individual red instrument lighting (instrument panel); indirect red lighting for checkoff lists and stand-by compass; warning, caution, and advisory lights; a utility light (RA-5C, only); and left and right emergency lights.

All exterior lighting was controlled from the pilot's.cockpit. All interior lighting was controlled independently. Additionally, the buddy tanker signal lights were controlled from the aft cockpit. Armament and Sensors: The armament system was

utilized on the A-5A to release weapons or fuel dump tanks mounted externally under the wings or internally in the linear bomb bay. In the RA-5C, the armament system was optimized for the release of externally mounted weapons or fuel drop tanks. Externally mounted items could be forcefully ejected from each MAU-9 rack by two electrically actuated explosive cartridges which operated linkage that freed support lugs from the pylon hooks and drove the rack ejector foot. The trigger was located on the pilot's stick grip. The rearward ejecting bomb system developed for the Vigifante and abandoned in principle upon the advent of the RA-5C was simple in concept, but extraordinarily complex in execution. The basic system consisted of the bomb tunnel (linear bomb bay) located between the aircraft engine bays (and accessed for maintenance by removing a 35 in. wide by 150 in. long non-structural panel on the underside of the fuselage), a bomb dolly track, the bomb dolly, the bomb, two trailing fuel cans (tanks), a solid fuel, gas actuated "kicker" for bomb and bomb train ejection, and a disposable tail cone. Several different bomb and bomb train configurations were tested (see "History" section) but none was perfected to the point where operational deployment was possible. The standard special (nuclear) weapons that were to have been utilized included the Mk.27, Mk.28, and Mk.43. The Vigifante also was designed to carry 2 x Mk.83 or 2 Mk.84 general purpose bombs on its wing pylons. Additionally, it was possible to carry two Mk.43 special stores on the pylons. Miscellaneous items eventually carried by the RA-5C in an operational scenario included the AN/ALQ-31 electronic countermeasures pod, and a pair of night flasher pods (assigned to Station 9-which was the inboard Wing

32

attachment point). The latter units were developed specifically for use with the RA-5C and were streamlined and faired to fit snugly against the underside of the aircraft's wings. Internal generators driven by wind turbines provided power for each unit's three strobe lights. The latter were synchronized to work in concert with the aircraft's optical sensors. The various mission of the RA-5C required different packages of eqUipment for obtaining reconnaissance data. The data obtained was utilized during post mission analysis for future mission planning. Systems providing reconnaissance data collection capabilities were the photographic systems, side-looking-radar system, infrared system, and passive electronic countermeasures

system. The digital data system provided control signals for these systems, and information required for full utilization of the data obtained from the reconnaissance systems. This data was complementary since, by comparison, more information could be obtained than would be possible by using any single system. The following list covers the standard systems and their components: Photographic: The aerial photographic systems installed in the RA-5C provided the aircraft with a capability of obtaining day and night high-resolution aerial photographs over a broad range of aircraft speed, altitude, and atmospheric conditions. All camera systems were controlled from a camera control panel located in the RAN's compartment, with the pilot having the means of taking over control of the oblique still picture cameras via a front COCkpit camera control panel. Control was accomplished automatically and governed by constants applied by the IMC and shutter control assembly in Station 5 (for serial frame cameras) and by self-contained control electronics (for panoramic cameras). The RAN's control panel included exposure remaining counters and readiness indicators for each camera. On some aircraft (having AFC 312 complied with) oblique camera sight assemblies were installed on the left and right sides of the pilot's canopy. During the course of the RA-5C's operational career, requirements changed from missions at medium altitudes to very low altitudes. High-altitude photography required cameras with longer focal lengths and high-resolution lenses to maintain a scale that would provide sufficient image size and produce enough resolution for detailed stUdy. Low-altitude photography required short focal length lenses to provide a reasonable field of coverage. To fulfill these requirements, two panoramic cameras (one

for low-altitude and one for high-altitude) were installed with rotating prisms which scanned from horizon to horizon to obtain wide rectangular overlapping frames in the direction of flight. Still picture (serial frame) cameras, exposing a series of overlapping square frames, also were installed at various stations to accomplish additional specific photographic reconnaissance recordings. The serial frame and panoramic cameras incorporated an SIC control on the lens cone or lens train assembly. The SIC control accommodated factors such as film type, filter type, altitude, target reflectivity, target type, location, season of the year, time of day, and ground cover variations. This information was preset prior to flight. Each camera installation also was equipped with a light sensor, providing integrated control of exposure within preset limits. Automatic exposure settings could be overridden by the RAN. Image motion compensation (IMC) was provided through the camera control systems. Input signals of aircraft ground speed were integrated with altitude signals from the air data computer or radar altimeter. Correct IMC was achieved when film motion relative to the ground was zero.

The camera stations were as follows: Sensor Station 1 (Forward Oblique): contained a forward oblique KA-51A or KA-51B, 6 in. focal length (FL) serial frame (S/F) camera. This unit was secured to fixed mounts which could be installed or provide 11.5° or 16° depression angles from the FRL. The camera was used for day photography only and operated in the pulse mode of operation (without IMC) with 50% forward overlap approximately 10° from the bottom of the format, regardless of the position of the mode seiector switch. The operation of the FlO camera could be controlled either from the pilot's oblique camera control panel or from the RAN's camera control panel. Sensor Station 2 (AzimuthNertical Camera): contained an azimuth/vertical (AzlV) S/F camera. A KA-50A (1-3/4 in. FL), KA-62A (3 in. FL), or KA-51NB (6 in. FL) camera could be used in sensor station 2. A switching arrangement was used to obtain proper IMC action (autocycle and overlap) for the three different FLs; the camera was mounted in an azimuth controlled mount secured to position the camera at approXimately a 90° depression angle at a normal level flight attitude (camera axis was at an angle of 94° to the FRL). In addition to providing a mounting surface for the camera, the azimuth-controlled mount was supplied with signals to correct the camera for aircraft drift angles as large as + or - 10°. This station

· ~.

could be used for night, as well as day, photo missions; however, night missions employed the 6 in. FL camera in order to maintain the complete camera field of view

within the flasher cone of light. This station was operated by the RAN only, and provided 60% overlap in either highor low-altitude mode with the 1-3/4 in. or 3 in. FL camera installed. The 6 in. FL camera provided 20% overlap in the high-altitude mode and 60% in the low-altitude mode. The azimuth/vertical camera also could be operated to form part of a tri-fan camera configuration with the obliques in station 4. Sensor Station 4: could house one of three modules in various configurations. Each module was identical in shape but contained a diversified camera arrangement. Module No. 4-1-in the forward compartment housed the right and left oblique serial frame cameras. They could be of various focal lengths, hard-mounted, to provide various depression angles. The two 6 in. FL cameras could be installed at a 5°, 19.75°, 37.5°, or 52° depression angle. If tri-fan coverage was desired, these depression angles were determined by the camera focal length used in Station No.2. Some No. 4-1 modules were modified to house two KA-53A (12 in. FL) cameras installed at depression angles of either 5° or 19.75°. The right and left oblique cameras were used for daylight missions and could operate in either the non-IMC (pulse) mode or the IMC (autocycle mode). Operation of these cameras could be controlled from either the pilot's control panel or the RAN's control panel. Module No. 4-1 (Configuration A)-contained the same oblique camera arrangement as the No. 4-1 module, but a 3 in. pan camera, controlled from the RAN's control panel, was included in the aft part of the module. Module No. 4-2-contained provisions to accommodate an 18 in. FL KA-58A panoramic camera in the forward compartment and a 3 in. FL KA-57A panoramic camera in the aft compartment. These cameras were controlled by the RAN and were mounted in fUlly stabilized mounts. The 3 in. pan provided the normal 60% overlap while the 18 in. pan provided 66% forward overlap. Both cameras operated in the IMC mode. Flights made at very high altitudes required a 5 hr. preheat of the 18 in. FL pan camera to obtain the highest resolution imagery. The prisms enclosure for these cameras contained a heater,

a thermostat, and a blower to aid in preheating. A barometric altitude signal was provided in conjunction with the PHC 36 modification available on select KA-5BA camera assemblies.

Module No. 4-3-<:ould accommodate two 6 in. FL serial frame cameras installed in fully stabilized mounts providing ptich and roll stabilization of + or - 5° and azimuth correction of + or - 10°. In the normal level flight altitude, the camera depression angle was approximately 90°; however the camera axis was set at 94° with respect to the FRL. This module also could accommodate the 1-3/4 in. FL camera. Module No. 4-3 (Configuration A)-housed 12 in. FL serial frame cameras in the forward compartment of the module, mounted in a split vertical configuration. The cameras were fixed-mounted with a depression angle of 81°. An optional configuration was the single 12 in. FL camera mounted vertically. Either configuration could be operated from the RAN's control panel. The split 12 in. FL configuration provided approximately the same lateral coverage as a 6 in. FL camera with twice the scale. The single 12 in. FL vertical configuration provided approximately half the laterai coverage of the 6 in. FL camera with twice the scale. Electronic flasher pods were available for night photography. These were installed at wing station 110 (right and left) and supplied directed high-intensity light in a 43° cone of illumination. The flasher pods operated in conjunction with the station 2 or station 4 vertical cameras (6 in. FL). Because of camera and flasher synchronization requirements, only one night vertical camera station (4 or 2) could be used at a time. The flasher pod capacitor system operated at 2,600 volts. The RA-5C also was equipped with a Westinghousemanufactured side-looking airborne radar (SLAR) system designated AN/APD-7. This dual, planar antenna equipped unit was mounted in the aft part of the ventral canoe and provided low-resolution video projected imagery of ground targets. Because of its limited resolution, the SLAR was used primarily for change detection and cueing the interpreter to areas of interest on other sensors. It also was very useful in harbor/ocean surveillance and in selecting radar significant offset aim-

points. The most important advantages of the system were its true all-weather, day/night capability and its ability to image large areas on a small amount of film. This data also had the attribute of being available for near real-time transmission back to analysis faciiities located many hundreds of miles from the RA-5C. The RA-5C also was equipped with an AN/AAS-21 infrared detecting set. Commonly referred to as the IR mapping system, this equipment detected, recorded, and photographed surface infrared (heat) radiation. It consisted of a receiver set (scanner), a recorder, a control panel, and an advisory light. The receiver and recorder were located in the recon package sensor station 7, forward of the three-headed video amplifier and between the SLAR antennas. The control panel was located on the RAN's aft left-hand console. An aerodynamic fairing protected the IR receiver scanner optics behind a sliding door assembly. Infrared information was gathered by the receiver scan mirror's rotation about an axis parallel to the aircraft track. Ground mapping presentation was focused by an optical system on a six-detector array and converted to electrical impulses. The electrical impulses were recorded on a 5 in. wide film as an IR map of the radiation. The field of view was 140°.

The RA-5C also was equipped with a passive electronic countermeasures system (PECM) designated AN/ALO61. This was a multiband, passive detection and recording set. It received emitter signals and recorded source characteristics, source bearing, time of recording, naviga· tional data, and status information data on tape for use by intelligence personnel. The recording tape system would record continuously for up to 56 or 112 minutes. The system was controlled from the RAN's compartment. The RA-5C was equipped with a digital data system designated AN/AYA-1. This collected aircraft flight data from the AN/ASB-12, the radar altimeter, the AN/APN120, and the A1A24G-4 air data computer set. This data, in turn, was processed in the CV-140B/AYA-1 data converter and the CV-1412/AYA-1 data translator and distributed to the various reconnaissance systems in the form of digital data matrix and tape format signals and analog stabilization and reference voltages. The number and types of video amplifiers installed on the aircraft

depended on the type of reconnaissance package installed. The sensory records from the RA-5C were processed and analyzed in the 10lC immediately upon return of the aircraft from its mission. Film magazines were passed into

the Film Handling Dark Room for development while airborne tapes of PECM data were loaded on the Magnetic Tape Processors. Options available for processing the PECM tapes included: prescribed locations examined in a specified order; all emitters of a certain type examined first; and/or the entire tape processed as recorded without established priorities. The output of this processing was a teletype report listing emitter locations and characteristics and a map overlay of emitter locations, produced by a digital plotter with symbols to indicate emitter type at each location. Three stereometric viewers, capable of both rear projection and stereoscopic direct viewing, were used for interpretation of imagery data. The annotated flight data on the film segments could be read and displayed by the viewer and used to select automatically segments to be viewed. A general-purpose digital computer provided on-line solution of geographic location and mensuration problems. Digital plotters at each viewing station produced sketch plots, map overlays, and map substitutes. Teletype writers were used for report generation and for communication between operator and computers. Filmed

material provided data on enemy troops and non-emitting installations and equipment, as well as a positive description and location of emitters.

Through analysis and interpretation of the newly collected data, the appropriate segments of the existing data base which had been drawn from storage and retrieval were updated and used for decision making. The updated material was returned to storage for later retrieval.

J79-GE-10 engine were installed in aircraft BuNos. 156608 through 156643 and 145157 through 151728 having AFC 328 complied with. These aircraft had provisions for installation of either J79-GE-8 or -1 0 engines. RA-5Cs powered by J79-GE-1 0 engines and having the associated wider intakes and extended wing root fillets had a 900 lb. greater zero fuel operating weight (40,900 Ibs. vis 40,000 Ibs.) than earlier RA-5Cs. ""On aircraft having AFC 247 complied with, the engine fuel system was modified to provide for a speed modulated afterburner thrust system (SMATS), and the engine was redesignated J79-GE-8C. SMATS had the advantage of reducing the thrust response transient times between approach power and minimum or maximum alb

power by having the alb in operation at all engine speeds. Total weight of the J79-GE-8 was 4,077 Ibs.; total weight of the J79-GE-1 0 was 4,330 Ibs. The J79-GE-8 had a length of 208 in. and a diameter of 35.18 in.; the J79-GE-10 had a length of 209 in. and a diameter of 35.18 in. General Electric's J79 was developed during the early 1950s in response to a need for a propulsion system for the then-forthcoming Convair B-58 Hustler. Initially referred to as the J73-X24A, it eventually was redesignated J79. In production form, it proved a precedent setting design and was the first turbojet engine to incorporate variable stators, a modulated afterburner, and a variable area ejector nozzle all in one package. The J79 as utilized in the Vigilante was an axial-flow, afterburner-equipped turbojet engine consisting of a 17-stage compressor, 10 can-annular-type combustion chambers, a three-stage turbine, an afterburner, and a variable area exhaust nozzle. Air entering the compressor section was controlled automatically by variable positioning inlet guide vanes which acted as an inlet air meter-

The first six stages of the 4 piece, steel case compressor were equipped with six rows of variable positioning steel stator vanes which were positioned so that at a particular engine speed and compressorlinlet temperature, the inlet air struck the vanes at the most effective angle. There were 11 rows of fixed steel blades. The inlet guide vanes and variable stator vanes were connected externally and rotated in unison to control compressor pressure ratio and maintain an adequate stall margin under all operating conditions. Turbine impingement starting provisions were incorporated. The cannular combustors were two-piece units with a steei outer shell and ten interconnected flame tubes of Incoloy "T" alloy. There were ten duplex type fuel burners around the diffuser section, with downstream injection via 10 fuel nozzles. The turbine was of the 3-stage axial fiow type. It had a two-piece steel casing with hollow nozzle vanes and solid stator blades. The turbine wheels had solid blades and were flange-bolted to the conical drive shaft. Each engine was variable-thrust afterburner equipped. The afterburners were self-igniting and self-controlled by separate torch igniters, afterburner fuel pumps, and fuel control units. The fuel spray bars were at the front end, with downstream injection. The afterburners normally ignited some 3 seconds after the throttles were moved outboard of the Military detent and forward into afterburner range. Combined engine and afterburner fuel flow at maximum settings was approximately four times that of the engine in Military power. Each engine was equipped with a variable area exhaust nozzle consisting of 24 sectional shutters and 4 hydraulic actuators. This nozzle was optimized to provide optimum thrust while maintaining exhaust gas temperatures within design limits. This was attained by an automatic system that monitored speed derivative signals eminating from engine rpm and EGT. These signals caused the nozzle amplifier to compare rates of rpm and EGT change and adjust the nozzle opening to maintain a temperature of 625° C, accordingly. Each engine was provided with a fuel control system (which consisted of two separate systems-one for engine fuel control and one for afterburner fuel control: these regulated engine speed by supplying and controlling fuel flow; the system also positioned the inlet guide and variable stator vanes of the compressor section and initiated alb operation) and a main ignition system (of which there were two-one main and one for the afterburner). The oil supply tank for each engine was installed around the upper right quadrant in the region of the front compressor case. The oil tank had a capacity of 4-1/2 gals. Each engine was equipped with a variable inlet ramp system that served to slow supersonic air to subsonic velocities by the time it reached the engine compressor face. Inlet air pressure recovery was accomplished through controlled velocity reduction by variable ramps. Each inlet duct contained three ramps. The first ramp was a fixed, 8.5° wedge. The second ramp had a slotted surface for bleeding turbulent boundary layer air and was hydraulically variable from 0° to 21.5° (0° to 24.0° for the RA-5C) down. The third ramp was separated from the second by a slot and moved with the second ramp to form a variable geometric inlet. The ramp system reduced duct air velocity and provided satisfactory pressure recovery through creation of a series of shock waves in the air stream ahead of the duct lip. To match engine demand with duct supply, an electrically driven, modulating bypass gap was mounted around the front frame of each engine. The gap passed excess duct airflow around the engine, through the engine compartments, and out the afterburner ejector nozzles. The excess air provided the secondary airflow for engine compartment and engine cooling. The ramps and gaps were automatically scheduled and controlled by an electrical inlet control system. Below .95 Mach, the variable ramps were maintained in the fully retracted position; above .95 Mach, the variable ramps were automatically positioned by hydraulic actuators in accordance with a programmed schedule, increasing to about 15° down at maximum speed. At high supersonic speeds, inlet airflow was decelerated through two oblique shock waves and a normal shock wave. The ramp schedule provided for good engine performance throughout the airspeed envelope and safety back-ups were provided in case of failure. With the advent of the J79-GE-10, the increased mass flow requirements of this engine led to a redesign of the Vigilante's intake configuration. Increased capture area

resulted, this being visible in the form of a straight ramp side edge (along with this upgrade, wing leading edge root extensions [LERCs] were added to enhance longitudinal control while operating in the low speed end of the performance envelope). Enlarging the intakes necessitated widening the ramps and curtains, and, as a result, it was necessary to revise the ramp and gap scheduling. Other changes integral with the integration of the J79-GE-10 included beefed-up engine mounts, epoxy paint used in lieu of acrylic lacquer on exterior surfaces of the aircraft, deletion of paint from the leading edge flaps, added ground operation capability for inflating the aircraft's canopy seals, and a new arresting hook bumper with external servicing provisions. Landing gear, corrosion, electrical system, and flight control improvements also were incorporated at this time. The A-5A fuel supply system included a sump tank, an aft (saddle) fuselage tank, integral wing tanks, provision for three bomb bay fuel cans, and two 400-gal. drop tanks. The fuselage sump tank, located immediately forward of the bomb bay, contained two dual-sReed boost pumps. All fuel from the other tanks was transferred into the sump tank and directed to the engine-driven fuel pumps. The integral wing tanks contained two dual-speed transfer pumps and two scavenge pumps. The aft fuselage saddle tank was located above the bomb, forward of the vertical stabilizer. It contained a level control valve and two transfer pumps. All internal tanks were pressurized to 5.5 psi. For normal missions, the A-5A had two expendable fuel cans installed in the linear bomb bay. Three cans could be installed for ferry flights. The cans were pressurized to 25 psi. Provisions also were made for the installation of a buddy tanker refueling package in the linear bomb bay. This package consisted of a 290 gal. buddy tank, two bomb bay fuel cans, a reel with 78 ft. of hose, a pump unit, and a flow scheduler. It was not jettisonable. Operation of the system was by the navigator through the buddy tanker control panel. A device for guillotining the hose in case of an emergency was provided. Two 400 gal. drop tanks could be instailed at the external store stations under the wings. These tanks were pressurized to 14 psi and could be jettisoned when depleted. All fuel in the aircraft could be jettisoned in an emergency, with jettison rates varying from tank to tank. A fuel dump vent was installed in the fairing on the trailing edge of the vertical tail. All internal tanks couid,be refueled in approximateiy 5 minutes through two pressure refueling receptacles. Aircraft equipped with drop tanks couid be refueled in approximately 7-1/2 minutes. The RA-5C (and A-5B) fuel supply system included a forward tank iocated aft of the main electronics bay, a sump tank located directly aft of the forward tank, wing tanks that inciuded an overwing (top cap) tank and integral units, a saddle-shaped aft tank located above the bomb bay forward of the vertical tail, two or three 295-gal. fuel cans installed in the linear bomb bay, and either two or four 400-gal. drop tanks installed at wing externai stores stations. All three Vigilante variants were equipped with a hydraulically actuated inflight refueling probe located on the left forward section of the nose, next to the pilot's cockpit. Fuel could be transferred using probe and drogue systems at a maximum rate of about 2,000 Ibs. per minute.

The Vigilante's engine bays utilized titanium as the primary structural material with approximately 2,400 Ibs. of the metal found in the engine bay areas. Noteworthy, too, is the fact that the engine bay in ner surfaces had heat-reflective gold film sprayed on and baked in place. An external power supply pod designated RCPP-105-1 was available for and transportable by the Vigilante. Powered by a small gas turbine engine, the pod provided 60Kva, 400 cps electricity, refrigeration for cooling avionics gear and the pilot's pressure suit, and bleed air for starting the engines. The pod weighed 1,638 Ibs. and was developed by Garrett AiResearch. It was 26.2 ft. long and had a maximum diameter of 2.9 ft. A trailerized, nonair-transportable version was designated RCPT-105-3.
