The Vought F7U Cutlass is a United States Navy carrier-based jet fighter and fighter-bomber designed and produced by the aircraft manufacturer Chance Vought. It was the first tailless production fighter in the United States as well as the Navy's first jet equipped with swept wings and the first to be designed with afterburners.[1]
The Cutlass was developed from the mid 1940s to early 1950s as Vought's entry in a United States Navy competition. Their design team, which was influenced by design information obtained from Nazi Germany, opted for a tailless configuration paired with low aspect ratio swept wings, which was regarded as a radical departure from traditional aircraft design for the era. Vought's submission was favoured by Navy officials and was declared the winner in 1946. On 29 September 1948, the prototype performed its maiden flight; all three prototypes would be lost during the flight test program. It was initially powered by a pair of Westinghouse J34 turbojet engines which were relatively underpowered, contributing to its accident-prone nature; its unreliable hydraulic flight control system was also a source of difficulties.
The first production model of the Cutlass, F7U-1, entered service during July 1951. It was promptly followed by F7U-2 and F7U-3, improved models that were equipped with more powerful engines amongst other refinements. However, the Cutlass continued to suffer from frequent technical and handling problems throughout the aircraft's short service career. Accidents involving the type were responsible for the deaths of four test pilots and 21 other U.S. Navy pilots.[2] Over one quarter of all Cutlasses built were destroyed in accidents; this high rate of accidents led to the type being withdrawn during the late 1950s despite having been in service for less than ten years.[3]
