The The Cavalier Mustang was a post-World War II civilian-modified version of the North American P-51 Mustang aircraft. Although originally intended as a high speed personal aircraft, the Cavalier was also exported for use as a fighter and close air support aircraft to third world air forces.
In 1967, a decade after creating their first civilian P-51 conversion, Trans Florida was contracted by the United States Department of Defense to create military specification F-51Ds for export. These military aircraft incorporated most of the improved features of the civilian Cavaliers but were optimized as ground attack fighters. These aircraft were called Cavalier F-51D
