The North American Aviation FJ-1 Fury, the first of a series of four Navy aircraft, was a single-engine, single-seat, low-wing monoplane with short stubby wings looking much like a high-flying bomb. With the air intake, engine and fuel tanks enclosed within the airplane, the fighter was given super-thin, high-speed laminar flow wings. The FJ-1 was the first American jet fighter to employ a single, straight ram duct with its entrance in the nose. Later versions, the -2, -3 and -4 models, were designed with swept wings for operation at higher altitudes and faster speed over a greater range than earlier Fury jets.
