Vought F7U Cutlass

The Vought F7U Cutlass was a United States Navy carrier-based jet fighter and fighter-bomber of the early Cold War era.

It was a tailless aircraft for which aerodynamic data from projects of the German Arado and Messerschmitt companies, obtained at the end of World War II through German scientists who worked on the projects, contributed, though Vought designers denied any link to the German research at the time.

The F7U was the last aircraft designed by Rex Beisel, who was responsible for the first fighter ever designed specifically for the U.S. Navy, the Curtiss TS-1 of 1922.
