Variants McDonnell CF-101 Voodoo

Development of the F-101 commenced during the late 1940s as a long-range bomber escort (then known as a penetration fighter) for the United States Air Force's (USAF) Strategic Air Command (SAC). It was also adapted as a nuclear-armed fighter-bomber for the USAF's Tactical Air Command (TAC), and as a photo reconnaissance aircraft based on the same airframe. On 29 September 1954, it performed its maiden flight. The F-101A set a number of world speed records for jet-powered aircraft, including fastest airspeed, attaining 1,207.6 miles (1,943.4 km) per hour on 12 December 1957.[1]

Delays in the 1954 interceptor project led to demands for an interim interceptor aircraft design, a role that was eventually won by the F-101B Voodoo. This role required extensive modifications to add a large radar to the nose of the aircraft, a second crew member to operate it, and a new weapons bay using a rotating door that held its four AIM-4 Falcon missiles or two AIR-2 Genie rockets hidden within the airframe until it was time to be fired. The F-101B entered service with USAF Air Defense Command in 1959 and the Royal Canadian Air Force (RCAF) in 1961. While the Voodoo was a moderate success, it may have been more important as an evolutionary step towards its replacement in most roles, the F-4 Phantom II, one of the most successful Western fighter designs of the 1950s; the Phantom would retain the twin engines, twin crew for interception duties, and a tail mounted well above and behind the jet exhaust, although it was an evolution of the F3H Demon while the Voodoo was developed from the earlier XF-88 Voodoo.

The Voodoo's career as a fighter-bomber was relatively brief, but the reconnaissance versions served for some time. Along with the US Air Force's Lockheed U-2 and US Navy's Vought RF-8 Crusaders, the RF-101 reconnaissance variant of the Voodoo was instrumental during the Cuban Missile Crisis and saw extensive service during the Vietnam War.[2] Interceptor versions served with the Air National Guard until 1982, and in Canadian service, they were a front line part of NORAD until their replacement with the CF-18 Hornet in the 1980s. The type was operated in the reconnaissance role until 1979. US examples were handed off to the USAF Air National Guard where they were operated until 1982. The RCAF Voodoos were in service until 1984.

Design and development edit

Background and XF-88 edit

Initial design on what would eventually become the Voodoo began in June 1946 in response to a USAAF Penetration Fighter Competition launched just after World War II.[3] This competition called for a long-range, high-performance fighter to escort a new generation of bombers, similar to the wartime role of the North American P-51 Mustang in escorting the Boeing B-17 Flying Fortresses and Consolidated B-24 Liberators across contested airspace. McDonnell was amongst several companies to respond to the competition; their design benefitted from recently captured German research into high speed jet aircraft.[4][5]

On 14 February 1947, McDonnell was awarded a contract (AC-14582) to produce a pair of prototypes, designated XF-88 Voodoo.[6][7] The first prototype (serial number 46-6525), which was powered by two 3,000 lbf (13.3 kN) Westinghouse XJ34-WE-13 turbojets, flew from Muroc on 20 October 1948.[8][9] Preliminary testing revealed that while handling and range was adequate, the top speed was a disappointing 641 mph (1,032 km/h) at sea level.[10] After fitting McDonnell-designed afterburners to the second prototype, thrust was increased to 3,600 lbf (16.1 kN) with corresponding performance increases in top speed, initial rate of climb and reduced takeoff distance. Fuel consumption was greatly increased by use of the afterburners, however, reducing the range.[8][11]

Although the XF-88 won the "fly-off" competition against the competing Lockheed XF-90 and North American YF-93, the detonation of the first nuclear weapon by the Soviet Union resulted in the United States Air Force (USAF) (created in 1947) re-evaluating its fighter needs, with interceptors being more important and bomber escorts being of reduced priority, and it terminated the Penetration Fighter program in 1950.[12][13] Another factor in the termination was budgetary limitations.[9][7] Analysis of Korean War missions, however, revealed that contemporary USAF strategic bombers were vulnerable to fighter interception. In early 1951, the USAF issued a new requirement for a bomber escort, to which all major US manufacturers submitted designs.[14] The McDonnell design was a larger and higher-powered version of the XF-88 and won the bid during May 1951. To reflect the level of changes involved, the redesigned F-88 was designated F-101 Voodoo in November 1951.[15][16]

Enlarged design edit

The new design was considerably larger, carrying three times the initial fuel load and designed around larger, more powerful Pratt & Whitney J57 turbojets.[17] The greater dimensions of the J57 engines required modifications to the engine bays, and modification to the intakes to allow a larger amount of airflow to the engine. The new intakes were also designed to be more efficient at higher Mach numbers. In order to increase aerodynamic efficiency, reduce structural weight and alleviate pitch-up phenomena recently identified in-flight testing of the Douglas D-558-2 Skyrocket, an aircraft with a control surface configuration similar to the XF-88, the horizontal tail was relocated to the top of the vertical stabilizer, giving the F-101 its signature "T-tail". In late 1952, the mission of the F-101 was changed from "penetration fighter" to "strategic fighter", which entailed equal emphasis on both the bomber escort mission and on nuclear weapons delivery. The new Voodoo mock-up with the reconfigured inlets, tail surfaces, landing gear, and dummy nuclear weapon was inspected by Air Force officials in March 1953.[18] The design was approved, leading to an initial production order for 29 F-101As being placed on 28 May 1953. No prototypes were required as the F-101 was considered to be a straightforward development of the XF-88,[19] with the Cook-Cragie production policy, in which initial low-rate production would be used for testing without the use of separate prototypes, chosen instead.[20][21]

Changing roles and into production edit

Despite securing an order for the type, McDonnell received a stop order for production on 16 April 1954; this was due to a substantial cutback in funding for the USAF in general. Meaningful production activity was not resumed until a favourable instruction was received by the company on 2 November 1954.[22] At this point, the USAF gave McDonnell an operational deadline of early 1957.[23]

The first production aircraft, F-101A serial number 53-2418, performed its maiden flight on 29 September 1954 from Edwards AFB; during this fight, it attained a maximum speed of Mach 0.9 (960 km/h) at an altitude of 35,000 feet (11,000 m).[24] This aircraft, which is privately owned, has been moved to the Evergreen Maintenance Center in Marana, Arizona, restored, and now on display at the Evergreen Aviation & Space Museum in McMinnville, Oregon.[25] It was previously on display at the Pueblo Weisbrod Aircraft Museum.

The end of the conflict in Korea and the development of the jet-powered Boeing B-52 Stratofortress negated the need for fighter escort and the Strategic Air Command opted to withdraw from the program. Despite SAC's loss of interest, the F-101A had attracted the attention of Tactical Air Command (TAC), leading to the F-101 being reconfigured as a fighter bomber.[26][27] In this capacity, it was intended to carry a single nuclear weapon for use against tactical targets such as airfields. TAC requested numerous alterations to the F-101 to suit the new role, including additional apparatus to permit air-to-ground communication, provisions to carry external pods, and structural strengthening.[28][29]

Through the support of TAC, testing of the F-101 was resumed, with Category II flight tests beginning in early 1955. A number of problems were identified and were mostly resolved during this phase of development. Issues were found with the autopilot, hydraulics, viewfinder, and control system; McDonnell typically replaced unsatisfactory parts with redesigned counterparts.[30] One particular issue was the aircraft's dangerous tendency towards severe pitch-up when flown at a high angle of attack; this would never be entirely rectified.[31][32] However, the USAF was satisfied with the installation of an active inhibitor system to deter such instances.[33] Around 2,300 improvements were made to the F-101 between 1955 and 1956 ahead of full-rate production commencing in November 1956.[34]

Operational history edit

F-101A / RF-101G edit

On 2 May 1957, the first F-101A was delivered to the 27th Strategic Fighter Wing, which transferred to TAC in July that year,[20][35] replacing their F-84F Thunderstreak. The F-101A was powered by two Pratt & Whitney J57-P-13 turbojets,[19] allowing good acceleration, a high rate of climb, ease in penetrating the sound barrier in level flight, and a maximum performance of Mach 1.52. The F-101's large internal fuel capacity allowed a range of approximately 3,000 mi (4,828 km) nonstop.[36] The aircraft was fitted with an MA-7 fire-control radar for both air-to-air and air-to-ground use, augmented by a Low Altitude Bombing System (LABS) for delivering nuclear weapons,[19] and was designed to carry a Mk 28 nuclear bomb. The original intended payload for the F-101A was the McDonnell Model 96 store, a large fuel/weapons pod similar in concept to that of the Convair B-58 Hustler, but was cancelled in March 1956 before the F-101 entered service. Other operational nuclear payloads included the Mk 7, Mk 43, and Mk 57 weapons. While theoretically capable of carrying conventional bombs, rockets, or Falcon air-to-air missiles,[37][38] the Voodoo never used such weapons operationally.[39] It was fitted with four 20mm M39 cannon, with one cannon often removed in service to make room for a TACAN beacon-receiver.

The F-101 set a number of speed records, including: a JF-101A (the ninth F-101A modified as a testbed for the more powerful J-57-P-53 engines of the F-101B) setting a world speed record of 1,207.6 mph (1,943.4 km/h) on 12 December 1957 during "Operation Firewall",[40] beating the previous record of 1,132 mph (1,811 km/h) set by the Fairey Delta 2 in March the previous year. The record was then subsequently taken in May 1958 by a Lockheed F-104 Starfighter. On 27 November 1957, during "Operation Sun Run," an RF-101C set the Los Angeles-New York City-Los Angeles record in six hours and 46 minutes, the New York to Los Angeles record in three hours and 36 minutes, and the Los Angeles to New York record in three hours and seven minutes.[41]

A total of 77 F-101As were built, only 50 of which were ever used operationally while the remainder were used exclusively for experimental work.[35][38] They were gradually withdrawn from USAF service starting in 1966.[42] Twenty-nine survivors were converted to RF-101G specifications with a modified nose, housing reconnaissance cameras in place of cannons and radar. These served with the Air National Guard through 1972.[43][44]

RF-101A edit

In October 1953, the USAF requested that two F-101As be built as prototype YRF-101A tactical reconnaissance aircraft.[45][46] These were followed by 35 RF-101A production aircraft.[47] The RF-101A shared the airframe of the F-101A, including its 6.33 g (62 m/s²) limit, but replaced the radar and cannons with up to six cameras in the reshaped nose.[48][49] Various electronics were incorporated at the request of TAC.[50] Like all other models of the F-101, it had provision for both flying boom and probe-and-drogue in-flight refueling capability, as well as for a buddy tank that allowed it to refuel other aircraft.[37][51] It entered service in May 1957,[52][30] replacing the RB-57 Canberra.

On 6 May 1957, the RF-101A entered service, the first unit to operate the type being 363d Tactical Reconnaissance Wing, stationed at Shaw AFB, South Carolina.[53][54] During October 1962, RF-101As from the 363d Tactical Reconnaissance Wing performed reconnaissance sorties over Cuba during the Cuban Missile Crisis.[2] Allegedly, the aircraft's performance over Cuba highlighted its shortcomings as a reconnaissance aircraft, motivating a series of modifications to improve its performance.[55] All USAF RF-101As were phased out of service during 1971.[56]

During October 1959, eight RF-101As were transferred to Taiwan, which used them for overflights of the Chinese mainland.[57][58] These ROCAF RF-101A were modified with the RF-101C vertical fins and air intake; this intake was used to cool the drag chute compartment and eliminated the five minute limit on using the afterburners on the RF-101A.[59] Two were reportedly shot down.[citation needed]

F-101B / CF-101B / EF-101B edit

In the late 1940s, the USAF had started a research project into future interceptor aircraft that eventually settled on an advanced specification known as the 1954 interceptor. Contracts for this specification eventually resulted in the selection of the Convair F-102 Delta Dagger, but by 1952 it was becoming clear that few parts of the specification other than the airframe would be ready by 1954; the engines, weapons, and fire control systems were all going to take too long to get into service. Thus, an effort was started to quickly produce an interim supersonic design to replace the various subsonic interceptors then in service, and the F-101 airframe was selected as a starting point.[60]

Although McDonnell proposed the designation F-109 for the new aircraft (which was to be a substantial departure from the basic Voodoo),[61] the USAF assigned the designation F-101B.[62] It was first deployed into service on 5 January 1959, with the 60th Fighter-Interceptor Squadron.[63] Production of this model ended in March 1961.[64] The Voodoo featured a modified cockpit to carry a crew of two, with a larger and more rounded forward fuselage to hold the Hughes MG-13 fire control radar of the F-102. It had a data link to the Semi-Automatic Ground Environment (SAGE) system, allowing ground controllers to steer the aircraft towards its targets by making adjustments through the plane's autopilot. The F-101B had more powerful Pratt & Whitney J57-P-55 engines, making it the only Voodoo not using the −13 engines. The new engines featured a substantially longer afterburner than J57-P-13s. To avoid a major redesign, the extended afterburners were simply allowed to extend out of the fuselage by almost 8  ft (2.4 m). The more powerful engines and aerodynamic refinements allowed an increased speed of Mach 1.85.[37]

The F-101B was stripped of the four M39 cannons and carried four AIM-4 Falcon air-to-air missiles instead, arranged two apiece on a rotating pallet in the fuselage weapons bay.[37] The initial load was two GAR-1 (AIM-4A) semi-active radar homing and two GAR-2 (AIM-4B) infrared-guided weapons with one of each carried on each side of the rotating pallet.[65] After the first two missiles were fired, the door turned over to expose the second pair. Standard practice was to fire the weapons in SARH/IR pairs to increase the likelihood of a hit. Late-production models had provision for two 1.7-kiloton MB-1/AIR-2 Genie nuclear rockets on one side of the pallet with IR-guided GAR-2A (AIM-4C) on the other side. "Project Kitty Car" upgraded most earlier F-101Bs to this standard beginning in 1961.[39][66]

Between 1963 and 1966, F-101Bs were upgraded under the Interceptor Improvement Program (IIP; also known as "Project Bold Journey"), being outfitted with a fire control system enhancement against hostile ECM and an infrared sighting and tracking (IRST) system in the nose in place of the in-flight refueling probe.[67]

The F-101B was produced in greater numbers than the F-101A and F-101C, with a total of 479 being delivered by the end of production in 1961.[68][64] Most of these were delivered to the Air Defense Command (ADC) beginning in January 1959.[63] The only foreign customer for the F-101B was Canada, where it was locally referred to as the CF-101 Voodoo.[69]

The F-101B was withdrawn from ADC service between 1968 and 1971, with many surviving USAF aircraft transferred to the Air National Guard (replacing F-102s), serving until 1982.[70] The last Voodoo in US service (F-101B-105-MC, AF Ser. No. 58-300) was finally retired by the 2nd Fighter Weapons Squadron at Tyndall AFB, Florida on 21 September 1982.[71]

F-101C / RF-101H edit

The F-101A fighter-bomber had been accepted into Tactical Air Command (TAC) service despite a number of problems. Among others, its airframe had proven to be capable of withstanding only 6.33 g (62 m/s²) maneuvers, rather than the intended 7.33 g (72 m/s²).[33][28] An improved model, the F-101C, was introduced in 1957. It had a 500 lb (227 kg) heavier structure to allow 7.33-g maneuvers as well as a revised fuel system to increase the maximum flight time in afterburner.[72] Like the F-101A, it was also fitted with an underfuselage pylon for carrying nuclear weapons, as well as two hardpoints for 450-US-gallon (1,700 L) drop tanks.[37] A total of 47 F101Cs were produced.[72][44]

Originally serving with the 27th Tactical Fighter Wing at Bergstrom AFB, Texas, the aircraft was transferred in 1958 from TAC to the 81st Tactical Fighter Wing, part of United States Air Forces in Europe (USAFE) which operated three squadrons from the twin RAF air stations Bentwaters & Woodbridge.[73] The 78th Tactical Fighter Squadron was stationed at Woodbridge, while the 91st and 92nd were stationed at Bentwaters. The 81st TFW served as a strategic nuclear deterrent force, the Voodoo's long-range putting almost all of the Warsaw Pact countries, and targets up to 500 miles (800 km) deep into the Soviet Union within reach.

Both the A and C model aircraft were assigned to the 81st TFW and were used interchangeably within the three squadrons. Operational F-101A/C were upgraded in service with Low Angle Drogued Delivery (LADD) and Low Altitude Bombing System (LABS) equipment for its primary mission of delivering nuclear weapons at extremely low altitudes. Pilots were trained for high speed, low-level missions into Soviet or Eastern Bloc territory, with primary targets being airfields. These missions were expected to be one-way, with the pilots having to eject behind Soviet lines.[72]

The F-101C never saw combat and was replaced in 1966 with the F-4C Phantom II.[20] Thirty-two aircraft were later converted for unarmed reconnaissance use with the RF-101H designation. They served with Air National Guard units until 1972.[20][74]

RF-101C edit

Using the reinforced airframe of the F-101C, the RF-101C first flew on 12 July 1957,[20] entering service in 1958. Like the RF-101A, the RF-101C had up to six cameras in place of radar and cannons in the reshaped nose and retained the bombing ability of the fighter-bomber versions.[75] As it was intended to be flown unarmed, various passive defensive systems were incorporated, including the AN/APS-54 radar warning receiver.[76] It lacked a true all-weather capability due to the USAF choosing to eliminate the AN/APN-82 electronic navigation system planned for it.[77] 166 RF-101Cs were built, including 96 originally scheduled to be F-101C fighter-bombers.[48]

On 27 November 1957, during Operation Sun Run, an RF-101C piloted by then-Captain Robert Sweet set the Los Angeles-New York City-Los Angeles record in six hours and 46 minutes, and New York to Los Angeles record in three hours and 36 minutes. Another RF-101C, piloted by then-Lieutenant Gustav Klatt, set a Los Angeles to New York record of three hours and seven minutes.[41]

The RF-101C saw service during the Cuban Missile Crisis and soon followed the North American F-100 Super Sabres in October 1961, into combat when RF-101s from the 67th Tactical Reconnaissance Wing deployed to south east Asia, performing reconnaissance flights over Laos and Vietnam.[78] Operations in this theatre quickly exposed the need for nighttime reconnaissance, for which the aircraft was not originally equipped to perform.[79] The 1964 Project "Toy Tiger" fitted some RF-101C with a new camera package and a centerline pod for photo-flash cartridges. Some were further upgraded under the Mod 1181 program with automatic control for the cameras. Some officials remained dissatisfied with the RF-101C's nighttime photographic capability.[80][81]

The RF-101C acted as pathfinders for F-100 bombers during early strikes in the theatre.[82] The RF-101C sustained losses during the conflict, the first loss to enemy ground fire was recorded in November 1964, although close calls occurred as early as 14 August 1962; North Vietnamese air defenses became increasingly effective over time.[83][84] From 1965 through November 1970, its role was gradually taken over by the RF-4C Phantom II. In some 35,000 sorties, 39 aircraft were lost, 33 in combat,[85][86] including five to SAMs, one to an airfield attack, and one in air combat to a MiG-21 in September 1967. The RF-101C's speed made it largely immune to MiG interception. 27 of the combat losses occurred on reconnaissance missions over North Vietnam. In April 1967, ALQ-71 ECM pods were fitted to provide some protection against SAMs. Although the Voodoo could again operate at medium altitudes, the added drag and weight decreased the RF-101's speed enough to be vulnerable to the maneuverable (and cannon-equipped) MiGs and thus require fighter escort.

After its withdrawal from Vietnam, the RF-101C continued to serve with USAF units through 1979. In service, the RF-101C was nicknamed the "Long Bird"; it was the only version of the Voodoo to see combat.[87]

TF-101B / F-101F / CF-101F edit

Some of the F-101Bs were completed as dual-control operational trainer aircraft initially dubbed TF-101B, but later redesignated F-101F. Seventy-nine new-build F-101Fs were manufactured, and 152 more existing aircraft were later modified with dual controls. Ten of these were supplied to Canada under the designation CF-101F. These were later replaced with 10 updated aircraft in 1971.

RF-101B edit

 
The prototype RF-101B (s/n 57-0301)

In the early 1970s, a batch of 22 former RCAF CF-101Bs was delivered to the USAF and converted into RF-101B reconnaissance aircraft, each aircraft had its radar and weapons bay replaced with a set of three KS-87B cameras and two AXQ-2 TV cameras. An in-flight refueling boom receptacle was also installed. These aircraft served with the 192d Tactical Reconnaissance Squadron of the Nevada Air National Guard through 1975. They proved to be relatively expensive to operate and maintain and had a short service life.

during the late 1940s as a long range bomber escort then known as a penetration fighter for the United States Air Force s USAF Strategic Air Command SAC It was also adapted as a nuclear armed fighter bomber for the USAF s Tactical Air Command TAC and as a photo reconnaissance aircraft based on the same airframe On 29 September 1954 it performed its maiden flight The F 101A set a number of world speed records for jet powered aircraft including fastest airspeed attaining 1 207 6 miles 1 943 4 km per hour on 12 December 1957 1 Delays in the 1954 interceptor project led to demands for an interim interceptor aircraft design a role that was eventually won by the F 101B Voodoo This role required extensive modifications to add a large radar to the nose of the aircraft a second crew member to operate it and a new weapons bay using a rotating door that held its four AIM 4 Falcon missiles or two AIR 2 Genie rockets hidden within the airframe until it was time to be fired The F 101B entered service with USAF Air Defense Command in 1959 and the Royal Canadian Air Force RCAF in 1961 While the Voodoo was a moderate success it may have been more important as an evolutionary step towards its replacement in most roles the F 4 Phantom II one of the most successful Western fighter designs of the 1950s the Phantom would retain the twin engines twin crew for interception duties and a tail mounted well above and behind the jet exhaust although it was an evolution of the F3H Demon while the Voodoo was developed from the earlier XF 88 Voodoo The Voodoo s career as a fighter bomber was relatively brief but the reconnaissance versions served for some time Along with the US Air Force s Lockheed U 2 and US Navy s Vought RF 8 Crusaders the RF 101 reconnaissance variant of the Voodoo was instrumental during the Cuban Missile Crisis and saw extensive service during the Vietnam War 2 Interceptor versions served with the Air National Guard until 1982 and in Canadian service they were a front line part of NORAD until their replacement with the CF 18 Hornet in the 1980s The type was operated in the reconnaissance role until 1979 US examples were handed off to the USAF Air National Guard where they were operated until 1982 The RCAF Voodoos were in service until 1984 Contents 1 Design and development 1 1 Background and XF 88 1 2 Enlarged design 1 3 Changing roles and into

Summer 1962Initial design on what would eventually become the Voodoo began in June 1946 in response to a USAAF Penetration Fighter Competition launched just after World War II 3 This competition called for a long range high performance fighter to escort a new generation of bombers similar to the wartime role of the North American P 51 Mustang in escorting the Boeing B 17 Flying Fortresses and Consolidated B 24 Liberators across contested airspace McDonnell was amongst several companies to respond to the competition their design benefitted from recently captured German research into high speed jet aircraft 4 5 On 14 February 1947 McDonnell was awarded a contract AC 14582 to produce a pair of prototypes designated XF 88 Voodoo 6 7 The first prototype serial number 46 6525 which was powered by two 3 000 lbf 13 3 kN Westinghouse XJ34 WE 13 turbojets flew from Muroc on 20 October 1948 8 9 Preliminary testing revealed that while handling and range was adequate the top speed was a disappointing 641 mph 1 032 km h at sea level 10 After fitting McDonnell designed afterburners to the second prototype thrust was increased to 3 600 lbf 16 1 kN with corresponding performance increases in top speed initial rate of climb and reduced takeoff distance Fuel consumption was greatly increased by use of the afterburners however reducing the range 8 11 Although the XF 88 won the fly off competition against the competing Lockheed XF 90 and North American YF 93 the detonation of the first nuclear weapon by the Soviet Union resulted in the United States Air Force USAF created in 1947 re evaluating its fighter needs with interceptors being more important and bomber escorts being of reduced priority and it terminated the Penetration Fighter program in 1950 12 13 Another factor in the termination was budgetary limitations 9 7 Analysis of Korean War missions however revealed that contemporary USAF strategic bombers were vulnerable to fighter interception In early 1951 the USAF issued a new requirement for a bomber escort to which all major US manufacturers submitted designs 14 The McDonnell design was a larger and higher powered version of the XF 88 and won the bid during May 1951 To reflect the level of changes involved the redesigned F 88 was designated F 101 Voodoo in November 1951 15 16 Enlarged design edit The new design was considerably larger carrying three times the initial fuel load and designed around larger more powerful Pratt amp Whitney J57 turbojets 17 The greater dimensions of the J57 engines required modifications to the engine bays and modification to the intakes to allow a larger amount of airflow to the engine The new intakes were also designed to be more efficient at higher Mach numbers In order to increase aerodynamic efficiency reduce structural weight and alleviate pitch up phenomena recently identified in flight testing of the Douglas D 558 2 Skyrocket an aircraft with a control surface configuration similar to the XF 88 the horizontal tail was relocated to the top of the vertical stabilizer giving the F 101 its signature T tail In late 1952 the mission of the F 101 was changed from penetration fighter to strategic fighter which entailed equal emphasis on both the bomber escort mission and on nuclear weapons delivery The new Voodoo mock up with the reconfigured inlets tail surfaces landing gear and dummy nuclear weapon was inspected by Air Force officials in March 1953 18 The design was approved leading to an initial production order for 29 F 101As being placed on 28 May 1953 No prototypes were required as the F 101 was considered to be a straightforward development of the XF 88 19 with the Cook Cragie production policy in which initial low rate production would be used for testing without the use of separate prototypes chosen instead 20 21 Changing roles and into production edit nbsp F 101A AF Serial No 53 2418 at Pueblo Weisbrod Aircraft Museum Pueblo Colorado before restorationDespite securing an order for the type McDonnell received a stop order for production on 16 April 1954 this was due to a substantial cutback in funding for the USAF in general Meaningful production activity was not resumed until a favourable instruction was received by the company on 2 November 1954 22 At this point the USAF gave McDonnell an operational deadline of early 1957 23 The first production aircraft F 101A serial number 53 2418 performed its maiden flight on 29 September 1954 from Edwards AFB during this fight it attained a maximum speed of Mach 0 9 960 km h at an altitude of 35 000 feet 11 000 m 24 This aircraft which is privately owned has been moved to the Evergreen Maintenance Center in Marana Arizona restored and now on display at the Evergreen Aviation amp Space Museum in McMinnville Oregon 25 It was previously on display at the Pueblo Weisbrod Aircraft Museum The end of the conflict in Korea and the development of the jet powered Boeing B 52 Stratofortress negated the need for fighter escort and the Strategic Air Command opted to withdraw from the program Despite SAC s loss of interest the F 101A had attracted the attention of Tactical Air Command TAC leading to the F 101 being reconfigured as a fighter bomber 26 27 In this capacity it was intended to carry a single nuclear weapon for use against tactical targets such as airfields TAC requested numerous alterations to the F 101 to suit the new role including additional apparatus to permit air to ground communication provisions to carry external pods and structural strengthening 28 29 Through the support of TAC testing of the F 101 was resumed with Category II flight tests beginning in early 1955 A number of problems were identified and were mostly resolved during this phase of development Issues were found with the autopilot hydraulics viewfinder and control system McDonnell typically replaced unsatisfactory parts with redesigned counterparts 30 One particular issue was the aircraft s dangerous tendency towards severe pitch up when flown at a high angle of attack this would never be entirely rectified 31 32 However the USAF was satisfied with the installation of an active inhibitor system to deter such instances 33 Around 2 300 improvements were made to the F 101 between 1955 and 1956 ahead of full rate production commencing in November 1956 34 Operational history editF 101A RF 101G edit nbsp An F 101A at Edwards Air Force Base 1954On 2 May 1957 the first F 101A was delivered to the 27th Strategic Fighter Wing which transferred to TAC in July that year 20 35 replacing their F 84F Thunderstreak The F 101A was powered by two Pratt amp Whitney J57 P 13 turbojets 19 allowing good acceleration a high rate of climb ease in penetrating the sound barrier in level flight and a maximum performance of Mach 1 52 The F 101 s large internal fuel capacity allowed a range of approximately 3 000 mi 4 828 km nonstop 36 The aircraft was fitted with an MA 7 fire control radar for both air to air and air to ground use augmented by a Low Altitude Bombing System LABS for delivering nuclear weapons 19 and was designed to carry a Mk 28 nuclear bomb The original intended payload for the F 101A was the McDonnell Model 96 store a large fuel weapons pod similar in concept to that of the Convair B 58 Hustler but was cancelled in March 1956 before the F 101 entered service Other operational nuclear payloads included the Mk 7 Mk 43 and Mk 57 weapons While theoretically capable of carrying conventional bombs rockets or Falcon air to air missiles 37 38 the Voodoo never used such weapons operationally 39 It was fitted with four 20mm M39 cannon with one cannon often removed in service to make room for a TACAN beacon receiver The F 101 set a number of speed records including a JF 101A the ninth F 101A modified as a testbed for the more powerful J 57 P 53 engines of the F 101B setting a world speed record of 1 207 6 mph 1 943 4 km h on 12 December 1957 during Operation Firewall 40 beating the previous record of 1 132 mph 1 811 km h set by the Fairey Delta 2 in March the previous year The record was then subsequently taken in May 1958 by a Lockheed F 104 Starfighter On 27 November 1957 during Operation Sun Run an RF 101C set the Los Angeles New York City Los Angeles record in six hours and 46 minutes the New York to Los Angeles record in three hours and 36 minutes and the Los Angeles to New York record in three hours and seven minutes 41 A total of 77 F 101As were built only 50 of which were ever used operationally while the remainder were used exclusively for experimental work 35 38 They were gradually withdrawn from USAF service starting in 1966 42 Twenty nine survivors were converted to RF 101G specifications with a modified nose housing reconnaissance cameras in place of cannons and radar These served with the Air National Guard through 1972 43 44 RF 101A edit nbsp A 33rd Tactical Group RF 101A s n 54 1512 after landing at Udorn Royal Thai Air Force Base later transferred to Tan Son Nhut Air Base c 1965In October 1953 the USAF requested that two F 101As be built as prototype YRF 101A tactical reconnaissance aircraft 45 46 These were followed by 35 RF 101A production aircraft 47 The RF 101A shared the airframe of the F 101A including its 6 33 g 62 m s limit but replaced the radar and cannons with up to six cameras in the reshaped nose 48 49 Various electronics were incorporated at the request of TAC 50 Like all other models of the F 101 it had provision for both flying boom and probe and drogue in flight refueling capability as well as for a buddy tank that allowed it to refuel other aircraft 37 51 It entered service in May 1957 52 30 replacing the RB 57 Canberra On 6 May 1957 the RF 101A entered service the first unit to operate the type being 363d Tactical Reconnaissance Wing stationed at Shaw AFB South Carolina 53 54 During October 1962 RF 101As from the 363d Tactical Reconnaissance Wing performed reconnaissance sorties over Cuba during the Cuban Missile Crisis 2 Allegedly the aircraft s performance over Cuba highlighted its shortcomings as a reconnaissance aircraft motivating a series of modifications to improve its performance 55 All USAF RF 101As were phased out of service during 1971 56 During October 1959 eight RF 101As were transferred to Taiwan which used them for overflights of the Chinese mainland 57 58 These ROCAF RF 101A were modified with the RF 101C vertical fins and air intake this intake was used to cool the drag chute compartment and eliminated the five minute limit on using the afterburners on the RF 101A 59 Two were reportedly shot down citation needed F 101B CF 101B EF 101B edit nbsp A two seat McDonnell F 101B Voodoo of the Oregon Air National Guard nbsp CF 101 Voodoo 101060 from 409 Nighthawk Squadron CFB Comox on the ramp at CFB Moose Jaw in spring 1982 In the late 1940s the USAF had started a research project into future interceptor aircraft that eventually settled on an advanced specification known as the 1954 interceptor Contracts for this specification eventually resulted in the selection of the Convair F 102 Delta Dagger but by 1952 it was becoming clear that few parts of the specification other than the airframe would be ready by 1954 the engines weapons and fire control systems were all going to take too long to get into service Thus an effort was started to quickly produce an interim supersonic design to replace the various subsonic interceptors then in service and the F 101 airframe was selected as a starting point 60 Although McDonnell proposed the designation F 109 for the new aircraft which was to be a substantial departure from the basic Voodoo 61 the USAF assigned the designation F 101B 62 It was first deployed into service on 5 January 1959 with the 60th Fighter Interceptor Squadron 63 Production of this model ended in March 1961 64 The Voodoo featured a modified cockpit to carry a crew of two with a larger and more rounded forward fuselage to hold the Hughes MG 13 fire control radar of the F 102 It had a data link to the Semi Automatic Ground Environment SAGE system allowing ground controllers to steer the aircraft towards its targets by making adjustments through the plane s autopilot The F 101B had more powerful Pratt amp Whitney J57 P 55 engines making it the only Voodoo not using the 13 engines The new engines featured a substantially longer afterburner than J57 P 13s To avoid a major redesign the extended afterburners were simply allowed to extend out of the fuselage by almost 8 ft 2 4 m The more powerful engines and aerodynamic refinements allowed an increased speed of Mach 1 85 37 The F 101B was stripped of the four M39 cannons and carried four AIM 4 Falcon air to air missiles instead arranged two apiece on a rotating pallet in the fuselage weapons bay 37 The initial load was two GAR 1 AIM 4A semi active radar homing and two GAR 2 AIM 4B infrared guided weapons with one of each carried on each side of the rotating pallet 65 After the first two missiles were fired the door turned over to expose the second pair Standard practice was to fire the weapons in SARH IR pairs to increase the likelihood of a hit Late production models had provision for two 1 7 kiloton MB 1 AIR 2 Genie nuclear rockets on one side of the pallet with IR guided GAR 2A AIM 4C on the other side Project Kitty Car upgraded most earlier F 101Bs to this standard beginning in 1961 39 66 nbsp The AIM 4 Falcon side of the F 101B missile doorBetween 1963 and 1966 F 101Bs were upgraded under the Interceptor Improvement Program IIP also known as Project Bold Journey being outfitted with a fire control system enhancement against hostile ECM and an infrared sighting and tracking IRST system in the nose in place of the in flight refueling probe 67 The F 101B was produced in greater numbers than the F 101A and F 101C with a total of 479 being delivered by the end of production in 1961 68 64 Most of these were delivered to the Air Defense Command ADC beginning in January 1959 63 The only foreign customer for the F 101B was Canada where it was locally referred to as the CF 101 Voodoo 69 The F 101B was withdrawn from ADC service between 1968 and 1971 with many surviving USAF aircraft transferred to the Air National Guard replacing F 102s serving until 1982 70 The last Voodoo in US service F 101B 105 MC AF Ser No 58 300 was finally retired by the 2nd Fighter Weapons Squadron at Tyndall AFB Florida on 21 September 1982 71 F 101C RF 101H edit The F 101A fighter bomber had been accepted into Tactical Air Command TAC service despite a number of problems Among others its airframe had proven to be capable of withstanding only 6 33 g 62 m s maneuvers rather than the intended 7 33 g 72 m s 33 28 An improved model the F 101C was introduced in 1957 It had a 500 lb 227 kg heavier structure to allow 7 33 g maneuvers as well as a revised fuel system to increase the maximum flight time in afterburner 72 Like the F 101A it was also fitted with an underfuselage pylon for carrying nuclear weapons as well as two hardpoints for 450 US gallon 1 700 L drop tanks 37 A total of 47 F101Cs were produced 72 44 nbsp F 101C Voodoo of 81 TFW based at RAF Bentwaters in 1962Originally serving with the 27th Tactical Fighter Wing at Bergstrom AFB Texas the aircraft was transferred in 1958 from TAC to the 81st Tactical Fighter Wing part of United States Air Forces in Europe USAFE which operated three squadrons from the twin RAF air stations Bentwaters amp Woodbridge 73 The 78th Tactical Fighter Squadron was stationed at Woodbridge while the 91st and 92nd were stationed at Bentwaters The 81st TFW served as a strategic nuclear deterrent force the Voodoo s long range putting almost all of the Warsaw Pact countries and targets up to 500 miles 800 km deep into the Soviet Union within reach Both the A and C model aircraft were assigned to the 81st TFW and were used interchangeably within the three squadrons Operational F 101A C were upgraded in service with Low Angle Drogued Delivery LADD and Low Altitude Bombing System LABS equipment for its primary mission of delivering nuclear weapons at extremely low altitudes Pilots were trained for high speed low level missions into Soviet or Eastern Bloc territory with primary targets being airfields These missions were expected to be one way with the pilots having to eject behind Soviet lines 72 The F 101C never saw combat and was replaced in 1966 with the F 4C Phantom II 20 Thirty two aircraft were later converted for unarmed reconnaissance use with the RF 101H designation They served with Air National Guard units until 1972 20 74 RF 101C edit nbsp U S Air Force technicians prepare a McDonnell RF 101 Voodoo for a photo reconnaissance mission nbsp U S Air Force McDonnell RF 101C over Vietnam 1967 Using the reinforced airframe of the F 101C the RF 101C first flew on 12 July 1957 20 entering service in 1958 Like the RF 101A the RF 101C had up to six cameras in place of radar and cannons in the reshaped nose and retained the bombing ability of the fighter bomber versions 75 As it was intended to be flown unarmed various passive defensive systems were incorporated including the AN APS 54 radar warning receiver 76 It lacked a true all weather capability due to the USAF choosing to eliminate the AN APN 82 electronic navigation system planned for it 77 166 RF 101Cs were built including 96 originally scheduled to be F 101C fighter bombers 48 On 27 November 1957 during Operation Sun Run an RF 101C piloted by then Captain Robert Sweet set the Los Angeles New York City Los Angeles record in six hours and 46 minutes and New York to Los Angeles record in three hours and 36 minutes Another RF 101C piloted by then Lieutenant Gustav Klatt set a Los Angeles to New York record of three hours and seven minutes 41 The RF 101C saw service during the Cuban Missile Crisis and soon followed the North American F 100 Super Sabres in October 1961 into combat when RF 101s from the 67th Tactical Reconnaissance Wing deployed to south east Asia performing reconnaissance flights over Laos and Vietnam 78 Operations in this theatre quickly exposed the need for nighttime reconnaissance for which the aircraft was not originally equipped to perform 79 The 1964 Project Toy Tiger fitted some RF 101C with a new camera package and a centerline pod for photo flash cartridges Some were further upgraded under the Mod 1181 program with automatic control for the cameras Some officials remained dissatisfied with the RF 101C s nighttime photographic capability 80 81 The RF 101C acted as pathfinders for F 100 bombers during early strikes in the theatre 82 The RF 101C sustained losses during the conflict the first loss to enemy ground fire was recorded in November 1964 although close calls occurred as early as 14 August 1962 North Vietnamese air defenses became increasingly effective over time 83 84 From 1965 through November 1970 its role was gradually taken over by the RF 4C Phantom II In some 35 000 sorties 39 aircraft were lost 33 in combat 85 86 including five to SAMs one to an airfield attack and one in air combat to a MiG 21 in September 1967 The RF 101C s speed made it largely immune to MiG interception 27 of the combat losses occurred on reconnaissance missions over North Vietnam In April 1967 ALQ 71 ECM pods were fitted to provide some protection against SAMs Although the Voodoo could again operate at medium altitudes the added drag and weight decreased the RF 101 s speed enough to be vulnerable to the maneuverable and cannon equipped MiGs and thus require fighter escort After its withdrawal from Vietnam the RF 101C continued to serve with USAF units through 1979 In service the RF 101C was nicknamed the Long Bird it was the only version of the Voodoo to see combat 87 TF 101B F 101F CF 101F edit Some of the F 101Bs were completed as dual control operational trainer aircraft initially dubbed TF 101B but later redesignated F 101F Seventy nine new build F 101Fs were manufactured and 152 more existing aircraft were later modified with dual controls Ten of these were supplied to Canada under the designation CF 101F These were later replaced with 10 updated aircraft in 1971 RF 101B edit nbsp The prototype RF 101B s n 57 0301 In the early 1970s a batch of 22 former RCAF CF 101Bs was delivered to the USAF and converted into RF 101B reconnaissance aircraft each aircraft had its radar and weapons bay replaced with a set of three KS 87B cameras and two AXQ 2 TV cameras An in flight refueling boom receptacle was also installed These aircraft served with the 192d Tactical Reconnaissance Squadron of the Nevada Air National Guard through 1975 They proved to be relatively expensive to operate and maintain and had a short service life Variants edit nbsp RF 101C 55 MC 56 0220 assigned to 18th TRS 460th TRW This aircraft was shot down by
