United States Military Aircraft






At the end of the Second World War, the Americans made a great effort to secure German aeronautical research data, and the implication of this information were soon seen in revisions of designs already undertaken by American manufacturers. Vought became interested in Arado research into tail less aircraft, and the result was the V-346 fighter without a conventional tail for small overall size, high speed, and good climb rate. The US Navy ordered three XF7U-1 prototype in 1946, and the first of these flew in  September 1948 with nearly parallel chord wings of low aspect ratio, swept at 38 degrees, and carrying full span slats on the leading edges and wide span elevons of the trailing edges outboard of the large vertical surfaces. There followed 14 F7U-1 pre production aircraft. The F7U-1 was beset by numerous aerodynamic and engine problems, and did not enter operational service, a responsibility that fell to the much redesigned F7U-3 with different engines. The Cutlass was the first naval aircraft designed for reheated turbojets, and also introduced power controls with artificial Feel and an automatic stabilization system. Photo By Coll B. Thouanel

A air superiority fighter.
