Design and development

In September 1952, the United States Navy announced a requirement for a new fighter. It was to have a top speed of Mach 1.2 at with a climb rate of , and a landing speed of no more than .Goebel, Greg

Korean War experience had demonstrated that .50 caliber (12.7 mm) machine guns were no longer sufficient and as a result the new fighter was to carry a 20 mm (0.79 in) cannon. 4x20 mm had become Navy standard prior to the Korean war: F2H, F9F, F3D and also the F7U and F4D, among others, preceded the F8U. In response, the Vought team led by John Russell Clark, created the V-383. Unusual for a fighter, the aircraft had a high-mounted wing which necessitated the use of a fuselage-mounted short and light landing gear. The major contribution to the short main gear, however, was the variable incidence wing that meant the plane did not take off and land extremely nose up, which was a characteristic of swept and low aspect ratio winged fighters. The Crusader was powered by a Pratt and Whitney J57 turbojet engine. The engine was equipped with an afterburner which, on the initial production F8U-1 aircraft, increased the thrust of the engine from 10,200 lb to 16,000 lb, but, unlike later engines, had no intermediate thrust settings. The Crusader was the first jet fighter in US service to reach 1,000 mph; U.S. Navy pilot R.W. Windsor reached 1,015 mph on a flight in 1956. The most innovative aspect of the design was the variable-incidence wing which pivoted by 7° out of the fuselage on takeoff and landing (not to be confused with variable-sweep wing). This allowed a greater

s, dog-tooth notching at the wing folds for improved yaw stability, and liberal use of titanium in the airframe. The armament, as specified by the Navy, consisted primarily of four 20 mm (.79 in) autocannons; the Crusader happened to be the last U.S. fighter designed with guns as its primary weapon. They were supplemented with a retractable tray with 32 unguided Mk 4/Mk 40 Folding-Fin Aerial Rocket (Mighty Mouse FFARs), and cheek pylons for two guided AIM-9 Sidewinder air-to-air missiles. In practice, AIM-9 Sidewinder missiles were the F-8's primary weapon; the 20mm guns were "generally unreliable". Moreover, it achieved nearly all of its kills with Sidewinders. Vought also presented a tactical reconnaissance version of the aircraft called the V-392. Major competition came from the Grumman F-11 Tiger, the upgraded twin-engine McDonnell F3H Demon (which would eventually become the McDonnell Douglas F-4 Phantom II), and lastly, the North American F-100 Super Sabre hastily adapted to carrier use and dubbed the "Super Fury". In May 1953, the Vought design was declared a winner and in June, Vought received an order for three XF8U-1 prototypes (after adoption of the unified designation system in September 1962, the F8U became the F-8). The first prototype flew on 25 March 1955 with John Konrad at the controls. The aircraft exceeded the speed of sound during its maiden flight. The development was so trouble free that the second prototype, along with the first production F8U-1, flew on the same day, 30 September 1955. On 4 April 1956, the F8U-1 performed its first catapult launch from .

Fleet service

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.

Mishap rate

The Crusader was not an easy aircraft to fly, and was often unforgiving in carrier landings, where it suffered from 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 lower the relative landing speed for Crusader pilots. 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. The nozzle and air intake were so low when the aircraft was on the ground or the flight deck that the crews called the aircraft "the Gator". Not surprisingly, the Crusader mishap rate was relatively high compared to its contemporaries, the Douglas A-4 Skyhawk and the

. However, the aircraft did possess a desirable capability, as proved when several Crusader pilots took off with the wings folded and were able to land the aircraft. One of these episodes took place on 23 August 1960; a Crusader with the wings folded took off from Napoli Capodichino in full afterburner, climbed to and then returned to land successfully. The pilot reported that the control forces were higher than normal. The Crusader was capable of flying in this configuration, though the pilot would be required to reduce aircraft weight by jettisoning stores and dumping fuel before landing. 1,261 Crusaders were built. By the time it was withdrawn from the fleet, 1,106 had been involved in mishaps."U.S. Navy's transition to jets."

Vietnam War

When conflict erupted in the skies over North Vietnam, it was US Navy Crusaders from that first tangled with Vietnam People's Air Force (the North Vietnamese Air Force) MiG-17s, on 3 April 1965. The MiGs claimed the downing of a Crusader, 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 Crusader at

, the remaining F-8s returning safely to their carrier. At the time, the Crusader was the best dogfighter the United States had against the nimble North Vietnamese MiGs. 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

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 and the F-8 Crusader and a community trained to prevail in air-to-air combat was a key ingredient to success.

McCoy of VF-51, USS ''Bon Homme Richard''. The Crusader also became a "bomb truck" in war, with both ship-based U.S. Navy units and land-based US Marine Corps squadrons attacking communist forces in both North and South Vietnam.Mersky, 1998, p. back, side and table in Appendix B. US Marine Crusaders flew only in the south, while Navy Crusaders flew only from the small ''Essex''-class carriers. Marine Crusaders also operated in close air support missions. Despite the "last gunfighter" moniker, the F-8s achieved only four victories with their cannon; the remainder were accomplished with AIM-9 Sidewinder missiles,Grossnick and Armstrong 1997 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. While VPAF pilots claimed 11 F-8s shot down by MiGs, official US sources indicate that only three F-8s were lost in air combat, all of them during 1966, to cannon fire from opponents in MiG-17s. A total of 170 F-8 Crusaders would be lost to all causes – mostly ground fire and accidents – during the war.

F-8s from the American carrier USS ''Saratoga'', the Crusader was chosen and 42 F-8s were ordered, the last Crusaders produced. The French Crusaders were based on the F-8E, but were modified in order to allow operations from the small French carriers, with the maximum angle of incidence of the aircraft's wing increased from five to seven degrees and blown flaps fitted. The aircraft's 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.Stijger, 1993, p. 192. Deliveries of the new aircraft, dubbed the F-8E(FN), started in October 1964 and continued until February 1965, with the ''Aéronavale''s first squadron, ''Flotille'' 12F reactivated on 1 October 1964. To replace the old Corsairs, ''Flotille'' 14.F received its Crusaders on 1 March 1965.Stijger, 1993, pp. 192–193.Rochotte, Léon C., Ramon Josa and Alexandre Gannier

In 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 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'' for Operation Mirmillon off the coast of Libya, intended to calm Colonel Gaddafi down, with 12.F squadron. The escalation of the situation in the Persian Gulf, due to the Iran-Iraq conflict, triggered the deployment of ''Clemenceau'' task force and its air wing, including 12.F squadron. 1993 saw the beginning of the missions over the former Yugoslavia. Crusaders were launched from both carriers cruising 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.Stijgers, 1993, p. 195. 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.Stijgers, 1993, p. 194. In 1989, when it was realised 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.Stijgers, 1993, pp. 195–196.Michell 1993, p. 58.

''Milavia''.
Twenty-five of them were refurbished by Vought and the remaining 10 were used for spare parts. As part of the deal, the U.S. would train Philippine pilots using the TF-8A. The Crusaders were manned by the 7th Tactical Fighter Squadron at Basa Air Base and were mostly used for intercepting Soviet bombers. But due to lack of spares and the rapid deterioration of the aircraft, the remaining F-8s were grounded in 1988 and left on an open grass field at Basa Air Base. They were finally withdrawn from service in 1991 after they were badly damaged by the Mount Pinatubo eruption, and have since been offered for sale as scrap.
