# North American FJ-1 Fury

The North American FJ-1 Fury is an early turbojet-powered carrier-capable fighter aircraft used by the United States Navy (USN). Developed by North American Aviation (NAA) starting in 1945, it became the first jet aircraft in USN service to serve at sea under operational conditions. This first version of the FJ was a straight-winged jet, briefly operational during the transition to more successful designs. An evolution of the FJ-1 would become the land-based XP-86 prototype of the United States Air Force's enormously influential F-86 Sabre, which in turn formed the basis for the Navy's carrier-based, swept-winged North American FJ-2/-3 Fury.

## Design and development

In late 1944, the USN sought proposals for a follow-on aircraft to supplement its first jet fighter, the McDonnell XFD-1 Phantom; three competing proposals from NAA, McDonnell Aircraft Corporation and Vought were selected. The NAA NA-134 was ordered on 1 January 1945 as the XFJ-1 and would be developed in parallel with the Vought F6U Pirate (the competing McDonnell proposal would eventually evolve into the McDonnell F2H Banshee). The XFJ-1 was a straight-wing, tricycle gear fighter with a single General Electric J35 turbojet fed by an intake passing through the fuselage; to avoid bifurcating the intake and thus increasing drag, the cockpit was placed entirely above the intake duct, giving the aircraft a squat appearance. It was armed with six .50 BMG machine guns mounted next to the air intake, making it the last aircraft ordered by the USN to use .50 BMG guns as its primary armament. The wing, empennage, and canopy strongly resembled that of the piston-engined P-51D Mustang, North American Aviation's highly successful World War II fighter, enclosing a relocated cockpit accommodation further forward in relation to the Mustang's design, to ensure good forward pilot visibility for carrier operations.

## Operational history

The first flight of the prototype XFJ-1 was conducted on 27 November 1946, and the first of 30 deliveries of the improved NA-141, designated FJ-1, took place in March 1948. Flown by Navy squadron VF-5A, the FJ-1 made the USN's first operational aircraft carrier landing with a jet fighter at sea on 10 March 1948 aboard USS Boxer, pioneering US jet-powered carrier operations and underscoring the need for catapult-equipped carriers. The Fury was capable of launching without catapult assistance, but on a crowded flight deck the capability was of limited use. Taking off without a catapult launch limited the FJ-1 to a perilous, slow climb that was considered too risky for normal operations.
As German research into swept wing aerodynamics was not yet available when the design was finalized, the FJ-1 used a straight wing. Folding wings were not used because dive brakes mounted in the wings made them unfeasible. To conserve carrier deck space, a "kneeling" nose gear strut along with a swiveling "jockey wheel" allowed the FJ-1 to be stacked tail-high, close to another FJ-1.
Before the first production FJ-1 was even delivered, the initial order for 100 units was trimmed to only 30 because more promising naval fighter designs had entered development. The production aircraft were initially used in testing at NAS North Island, California. VF-5A, soon redesignated as VF-51, operated the type from Boxer in March 1948 and from USS Princeton in August 1948, but operations did not go well, and the aircraft proved to have weak landing gear. One of the four FJ-1s to operate from Princeton was destroyed in a hard landing on arrival and went over the side; fortunately the pilot was rescued, but further accidents resulted in the cancellation of the operations after only two days. Although VF-51 went to sea on Boxer one more time in May 1949, the FJ-1s were phased out afterwards in favor of the new F9F-2 Panther.
Ending its service career in U.S. Naval Reserve units, the FJ-1 was eventually retired in 1953. The one highlight in its short service life was VF-51's win in the Bendix Trophy Race for jets in September 1948. The unit entered seven FJ-1s, flying from Long Beach, California to Cleveland, Ohio, with VF-51 aircraft taking the first four places, ahead of two California Air National Guard Lockheed F-80 Shooting Stars.
