The North American Fury fighter was a short, squat airplane looking much like a high-flying bomb. 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. Extra fuel was stored in wingtip tanks. A special feature was the bending nose gear, so the fighter could kneel down on the crowded deck of an aircraft carrier. Built for carrier and land operations, the FJ-1 could take off from a landing field or a carrier flight deck with normal jet power. The Fury was the first jet fighter to complete an operational tour at sea. A total of 33 straight-wing Furies were built at first, but the later swept-wing versions filled the Navy's demand for an aircraft similar to the F-86.
