The Vought F-8 Crusader (originally F8U) was a single-engine, supersonic, carrier-based air superiority jet aircraft built by Vought for the United States Navy and Marine Corps, replacing the Vought F7U Cutlass, and for the French Navy. The first F-8 prototype was ready for flight in February 1955, and served principally in the Vietnam War. The Crusader was the last American fighter with guns as the primary weapon, earning it the title "The Last of the Gunfighters".
The RF-8 Crusader was a photo-reconnaissance development and operated longer in U.S. service than any of the fighter versions. RF-8s played a crucial role in the Cuban Missile Crisis, providing essential low-level photographs impossible to acquire by other means. U.S. Naval Reserve units continued to operate the RF-8 until 1987.
