The North American FJ-2/-3 Fury were a series of swept-wing carrier-capable fighters for the United States Navy and Marine Corps. The FJ-2 resulted from an effort to navalize the United States Air Force's F-86 Sabre. These aircraft featured folding wings, and a longer nose landing strut designed to increase angle of attack upon launch and to accommodate a longer oleo to absorb the shock of hard landings on an aircraft carrier deck.

Although sharing a U.S. Navy designation with its distant predecessor, the straight-winged North American FJ-1 Fury, the FJ-2/-3 were completely different aircraft. (The later FJ-4 Fury was again, a complete structural redesign of the FJ-3). The FJ-2 was one of the aircraft used to evaluate the first steam catapult on a US Navy aircraft-carrier.[1]

Design and development

FJ-2

By 1951, the Navy's existing straight-wing fighters were much inferior in performance to the swept-wing Soviet MiG-15 then operating in the Korean War; the swept-wing fighters in the Navy's development pipeline, including the Vought F7U Cutlass and F9F Cougar that were not yet ready for deployment.

As an interim measure, the Navy's Bureau of Aeronautics ordered a direct development of the swept-wing F-86E Sabres as the FJ-2. As the F-86 had not been designed to be carrier-capable, this involved some risk, but Navy pilots had observed that the F-86A actually had a lower landing speed than the F9F Panther. During carrier qualification trials the Navy informed Grumman that if the F9F-5 stall speed was not reduced by 12 mph (10 kn; 19 km/h) it would be removed from carrier operations at the same time that the FJ-2 was already making its debut into Navy squadrons.[2] North American's chief engineer at the time stated that the swept wing Sabre had handling and stall characteristics at low speeds comparable to the best straight winged airplanes.[3] The urgency behind the program was such that 300 (later reduced to 200) FJ-2 fighters were ordered before the prototypes had flown.

FJ-1 and FJ-2 in 1952

The first prototype to fly was actually the third aircraft ordered: Designated XFJ-2B and first flown on 27 December 1951, it differed only from a standard F-86E-10 in its armament, having four 20-mm Colt Mk 12 cannon instead of the six Colt-Browning M3 .50 machine guns of the Sabre. The second and third aircraft to fly were designated XFJ-2 and lacked armament, but were modified to be carrier-capable: They had an arrester hook and a longer nosewheel leg to increase angle of attack at take-off and landing, and catapult fittings. In August 1952 carrier trials were flown on USS Midway (CVB-41), followed by carrier qualification trials on USS Coral Sea (CVA-43) in October–December 1952. Results were less than satisfactory. Low-speed handling was considered poor, and the arrester hook and nose gear leg were insufficiently strong.

The first production aircraft flew on 22 November 1952. This FJ-2 incorporated further modifications for carrier operations: The track of the main landing gear was widened by eight inches, the outer wing panels folded upward, and the windscreen was modified to give the pilot a better view during approach. The FJ-2 also featured an all-moving "flying tail" without dihedral.[4] Because of problems experienced during launches with steam catapults, a number of FJ-2 later received a stronger nosewheel strut. Outwardly, the FJ-2 was hard to distinguish from an F-86, apart from Navy paint and the gun muzzles of the 20-mm cannon. The engine was the General Electric J47-GE-2, a navalized version of the J47-GE-27 used in the F-86F. The naval modifications of the FJ-2 had increased weight by about 500 kg over the F-86F, but unfortunately had not succeeded in delivering a fully carrier-capable fighter. A decision had already been made to give it to land-based squadrons of the US Marine Corps.

Construction was slowed due to demand for the F-86 in Korea; the FJ-2 was not produced in large numbers until after that conflict had concluded. Only seven aircraft had been delivered by then end of 1953, and it was January 1954 before the first aircraft was delivered to a Marine squadron, VMF-122. The Navy preferred the lighter F9F Cougar due to its superior slow-speed performance for carrier operations, and the 200 FJ-2 models built were delivered to the United States Marine Corps. The Marines did make several cruises aboard carriers and tried to solve the type's carrier handling problems, but the FJ-2 was never really satisfactory. In 1956, the FJ-2 already disappeared from front-line service, and reserve units retired it in 1957.[5]

Even while development of the FJ-2 was ongoing, the development was planned of a version powered by the Wright J65, a license-built version of the British Armstrong Siddeley Sapphire turbojet. The Sapphire promised to deliver 28% more thrust than the J47, for little gain in weight. The new version was designated FJ-3, and an order for 389 aircraft was placed in March 1952.

To test the new engine a single FJ-2, BuNo 131931, was modified, but the first true production FJ-3 flew on 3 July 1953.[6] The only externally visible change required by the new engine was a deeper intake to accommodate the larger mass flow. Early FJ-3s had the same wing as the FJ-2, but from 1955 onwards the FJ-3 was built with a so-called "6-3" wing, with a leading edge that was extended 6 inches at the root and 3 inches at the tip. This modification, first introduced on the F-86F, enhanced maneuverability at the price of a small increase in landing speed because the leading edge slats were deleted. The version introduced on the FJ-3 was different from that fitted to the F-86F, as camber was applied to the underside of the leading edge to improve low-speed handling. On the FJ-3, the new wing leading edges also held extra fuel. From the 345th aircraft onwards, the wings were provided with four stations for external loads, up to 1000 lb on the inboard stations and 500 lb on the outboard stations.

Deliveries began in September 1954, and the FJ-3 joined the fleet in May 1955. An FJ-3 was the first fighter to land aboard the new supercarrier USS Forrestal (CVA-59) in 1956. Problems were encountered with the J65 engine, including failures of its lubrication system under the acceleration of launch or during manoeuvres, and failures of the turbine blades. Nevertheless the Navy was more satisfied with the FJ-3 than it had been with the FJ-2, and in March 1954 it ordered an additional 149 aircraft. Because of its more powerful engine, the FJ-3 was superior to most models of the F-86, except the F-86H. A total of 538 FJ-3s were built. Of these 194 were modified to FJ-3Ms with the ability to carry AIM-9 Sidewinder air-to-air missiles. Some FJ-3s were later modified to control Regulus missiles (KDU-1), and F9F-6K Cougar target drones. In 1956 the Navy retro-fitted all its FJ-3s with probe-and-drogue air refueling equipment, a long probe being fitted under the left wing.[7]
