US Navy and US Marine Corps Introduction VX-3 was one of the first units to receive the F8U-1 in December 1956, and was the first to operate the type in April 1957, from . VX-3 was the first unit to qualify for carrier operations but several aircraft were lost in accidents, several of them fatal to their pilots. The first fleet squadron to fly the Crusader was
VF-32 at
NAS Cecil Field, Florida, in 1957, which deployed to the Mediterranean late that year on . VF-32 renamed the squadron the "Swordsmen" in keeping with the Crusader theme. The Pacific Fleet received the first Crusaders at
NAS Moffett Field in northern California and the
VF-154 "Grandslammers" (named in honor of the new 1,000-mph jets and subsequently renamed the "Black Knights") began their F-8 operations. Later in 1957, in San Diego
VMF-122 accepted the first Marine Corps Crusaders. The first combat action of F-8s was during the
1958 Lebanon crisis. F-8s of VF-32 were assigned to the USS
Saratoga in support of the landing of US Marines in Lebanon. In 1962, the Defense Department standardized military aircraft designations under the
Tri-Service Designation System. Consequently, the F8U became the
F-8, with the original F8U-1 redesignated
F-8A. , 1974. The Crusader became a "
day fighter" operating off the aircraft carriers. At the time, U.S. Navy carrier air wings had gone through a series of day and night fighter aircraft due to rapid advances in engines and avionics. Some squadrons operated aircraft for very short periods before being equipped with a newer higher performance aircraft. The Crusader was the first post-Korean War aircraft to have a relatively long tenure with the fleet.
Cuban Missile Crisis The unarmed RF-8A proved good at getting low-altitude detailed photographs, leading to carrier deployments as detachments from the Navy's
VFP-62 and
VFP-63 squadrons and the Marines'
VMCJ-2. Beginning on 23 October 1962 during the
Cuban Missile Crisis, RF-8As flew extremely hazardous low-level photo reconnaissance missions over Cuba, the F-8's first true operational flights. Two-ship flights of RF-8As left
Key West twice each day, to fly over Cuba at low level, then return to Jacksonville, where the film was offloaded and developed, to be rushed north to the Pentagon. These flights confirmed that the
Soviet Union was setting up
medium range ballistic missiles (MRBMs) in Cuba. The RF-8As also monitored the withdrawal of the Soviet missiles. After each overflight, the aircraft was given a stencil of a dead chicken. The overflights went on for about six weeks and returned a total of 160,000 images. The pilots who flew the missions received
Distinguished Flying Crosses, while VFP-62 and VMCJ-2 received the prestigious U.S.
Navy Unit Commendation.
Mishap rate RF-8A in 1963. The Crusader was not an easy aircraft to fly, and was often unforgiving in carrier landings, where it suffered poor recovery from high sink rates, and the poorly designed,
castering nose undercarriage made it hard to steer on the deck. Safe landings required the carriers to steam at full speed to offset the relatively high landing speed of the Crusader. The stacks of the oil-burning carriers on which the Crusader served belched thick black smoke, sometimes obscuring the flight deck, forcing the Crusader's pilot to rely on the
landing signal officer's radioed instructions. It earned a reputation as an "
ensign eliminator" during its early service introduction.

Gulf of Tonkin. When conflict erupted in the skies over
North Vietnam, it was US Navy Crusaders from that first engaged with North Vietnamese
Vietnam People's Air Force (VPAF)
MiG-17s, on 3 April 1965. The MiGs claimed the downing of an F-8 and Lt Pham Ngoc Lan's
gun camera revealed that his
cannons had set an F-8 ablaze, but
Lieutenant Commander Spence Thomas had managed to land his damaged F-8 at
Da Nang Air Base, the remaining F-8s returning safely to their carrier. The F-8 repeatedly encountered the relatively nimble North Vietnamese MiGs over the following years, yet the F-8 never made first contact via radar detection in any of these engagements. Instead, F-8 pilots were reliant on ground control intercept controllers to find enemies and be guided towards a favorable firing position. A typical day mission would be performed using a pair of F-8s, one pilot concentrated on radar and navigation functions while the other searched the skies with their eyes; ground controllers would alert and direct them towards any MiGs spotted, which they'd approach at speed from behind, not relying on their own radar to detect the hostile aircraft. The presence of US
surface to air missiles (SAMs) usually compelled MiGs to fly at lower altitudes, where the F-8 was more maneuverable and thus would have an advantage. The US Navy had evolved its "night fighter" role in the air wing to an all-weather interceptor, the F-4 Phantom II, equipped to engage incoming bombers at long range with
missiles such as
AIM-7 Sparrow as their sole air-to-air weapons, and maneuverability was not emphasized in their design. Some experts believed that the era of the dogfight was over as air-to-air missiles would knock down adversaries well before they could get close enough to engage in dogfighting. As aerial combat ensued over North Vietnam from 1965 to 1968, it became apparent that the dogfight was not over. In one pitched air-battle between USN F-8s and VPAF
MiG-21s on 1 August 1968,
ace fighter pilot Nguyen Hong Nhi fired a pair of
R-3S AAMs at a pair of F-8s, the second R-3S making a successful hit, claiming one F-8 shot-down. Following a brief dogfight with the other F-8, another pair of F-8s entered into the fray and fired two
Sidewinder AAMs at Nguyen Hong Nhi, who was hit and safely ejected from his stricken MiG-21; the downing of ace fighter pilot Nguyen is credited to F-8H pilot Lt. McCoy of
VF-51,
USS Bon Homme Richard. As the conflict progressed, North Vietnam received MiG-21s, which proved to be a more capable opponent for the F-8, yet it still proved to be effective with good teamwork and exploiting the MiG-21's weaknesses. Following the end of
Operation Rolling Thunder in November 1968, American aircraft stopped flying in airspace in which MiGs encounters were expected and thus there were fewer opportunities for aerial engagements to occur. Accordingly, the Crusader increasingly became used as a "bomb truck", with both ship-based U.S. Navy units and land-based US Marine Corps squadrons attacking communist forces in both North and South Vietnam. US Marine Crusaders flew only in the south, where they largely performed
close air support and
interdiction missions. During December 1972's
Operation Linebacker II, numerous Navy F-8s were assigned to fly aerial superiority missions, yet these were largely unopposed; actual combat with MiGs had become exceeding rare by this point of the conflict. Navy Crusaders flew only from the small
Essex-class carriers. Despite the "last gunfighter" moniker, the F-8s achieved only four victories with their cannon; the remainder were accomplished with Sidewinder missiles, partly due to the propensity of the 20 mm (.79 in)
Colt Mk 12 cannons' feeding mechanism to jam under G-loading during high-speed dogfighting maneuvers. Between June and July 1966, during 12 engagements over North Vietnam, Crusaders claimed four MiG-17s for two losses. Crusader pilots would claim the best kill ratio of any American type in the
Vietnam War, 19:3. Of the 19 aircraft claimed during aerial combat, 16 were MiG-17s and three were
MiG-21s. A total of 170 F-8s would be lost to all causes – mostly ground fire and accidents – during the war.
Withdrawal from frontline operations LTV built and delivered the 1,219th (and last) US Navy Crusader to
VF-124 at
NAS Miramar on 3 September 1964. The last active duty US Navy Crusader fighter variants were retired from
VF-191 and
VF-194 aboard in 1976 after almost two decades of service, setting a first for a Navy fighter. The photo reconnaissance variant continued to serve in the active duty Navy for yet another 11 years, with VFP-63 flying RF-8Gs up to 1982, and with the Naval Reserve flying their RF-8Gs in two squadrons (VFP-206 and VFP-306) at Naval Air Facility Washington /
Andrews AFB until the disestablishment of
VFP-306 in 1984 and
VFP-206 on 29 March 1987 when the last operational Crusader was turned over to the
National Air and Space Museum. The Crusader is the only aircraft to have used the AIM-9C, a radar-guided variant of the Sidewinder air-to-air missile. During 1969, the US Navy opted to shelve the AIM-9C due to its restrictive launch envelope, as well as its high maintenance demands and associated logistical difficulties. When the Crusader retired, these missiles were converted to the
AGM-122 Sidearm anti-radiation missiles used by United States attack helicopters against enemy radars.
NASA F-8A
supercritical wing testbed Several modified F-8s were used by
NASA in the early 1970s, with the
F-8 digital fly-by-wire project using data-processing equipment adapted from the
Apollo Guidance Computer to prove the viability of
digital fly-by-wire technology, and a second airframe used as a testbed for
supercritical wing design.
French Navy During the early 1960s, the French Navy's air arm, the
Aéronavale, required a carrier-based fighter to serve aboard the new carriers and , the F-4 Phantom, then entering service with the United States Navy, proved to be too large for the small French ships. Following carrier trials aboard
Clemenceau on 16 March 1962, by two
VF-32 F-8s from the American carrier USS
Saratoga, the Crusader was chosen and 42 F-8s were ordered; these would be the last Crusaders produced. The French Crusaders were based on the F-8E, but were modified in order to allow operations from the compact French carriers; accordingly, the maximum angle of incidence of the aircraft's wing increased from five to seven degrees and
blown flaps fitted. The weapon system was modified to carry two French Matra
R.530 radar or infra-red missiles as an alternative to Sidewinders, although the ability to carry the American missile was retained. Deliveries of these aircraft, dubbed the F-8E(FN), started in October 1964 and continued until February 1965, with the
Aéronavales first squadron,
Flotille 12F reactivated on 1 October 1964. During October 1974, (on
Clemenceau) and June 1977 (on
Foch), Crusaders from 14.F squadron participated in the Saphir missions over
Djibouti. On 7 May 1977, two Crusaders went separately on patrol against supposedly French Air Force (4/11 Jura squadron) F-100 Super Sabres stationed at Djibouti. The leader intercepted two fighters and engaged a dogfight (supposed to be a training exercise) but quickly called his wingman for help as he had actually engaged two
Yemeni MiG-21s. The two French fighters switched their master armament to "on" but, ultimately, everyone returned to their bases. This was the only combat interception to be performed by French Crusaders. The
Aéronavale Crusaders flew combat missions over Lebanon in 1983 escorting
Dassault-Breguet Super Étendard strike aircraft. In October 1984, France sent
Foch with 12.F squadron to conduct Operation Mirmillon off the coast of Libya, intended to deter Libyan ruler
Colonel Gaddafi from escalating. Regional tensions around the
Persian Gulf, largely related to the
Iran-Iraq conflict, triggered the deployment of a task force headed by
Clemenceau, which included 12.F squadron in its air way. During 1993, combat missions commenced over the skies of the former
Yugoslavia; Crusaders were launched from both French carriers, which were stationed in the
Adriatic Sea. These missions ceased in June 1999 with Operation Trident over
Kosovo. The French Crusaders were subject to a series of modifications throughout their life, being fitted with new F-8J-type wings in 1969 and having modified
afterburners fitted in 1979. Armament was enhanced by the addition of
R550 Magic infra-red guided missiles in 1973, with the improved,
all-aspect Magic 2 fitted from 1988. The obsolete R.530 was withdrawn from use in 1989, leaving the Crusaders without a radar-guided missile. In 1989, when it was realized that the Crusader would not be replaced for several years due to delays in the development of the Rafale, it was decided to refurbish the Crusaders to extend their operating life. Each aircraft was rewired and had its hydraulic system refurbished, while the airframe was strengthened to extend fatigue life. Avionics were improved, with a modified navigation suite and a new radar-warning receiver. The 17 refurbished aircraft were redesignated as F-8P (P used for "
Prolongé" -extended- and not to be confused with the Philippine F-8P). Although the French Navy participated in combat operations in 1991 during
Operation Desert Storm and over
Kosovo in 1999, the Crusaders stayed behind and were eventually replaced by the
Dassault Rafale M in 2000 as the last of the type in military service.
Philippine Air Force . c. 1978 During late 1977, the Philippine government purchased 35 secondhand U.S. Navy F-8Hs that had been stored at
Davis-Monthan AFB in Arizona. 25 of them were refurbished by Vought while the remaining ten were used for spare parts. Some of the inoperational airframes were refurbished for use as props in the 2000 movie
Thirteen Days, a dramatization of the
Cuban Missile Crisis, to depict the real-life RF-8As involved in the low-level photo reconnaissance missions that obtained photos of Soviet ballistic missiles in Cuba. ==Variants==
