In 1953, Bell Aircraft Corporation developed the Model 65 ATV VTOL research aircraft, with a pair of turbojets mounted on each side of the fuselage and could rotated at the aircraft center. The ATV program ended in 1955 and gave Bell experience with VTOL jet flight. This led to U.S. Air Force and Navy sponsorship of the project D-188A tilting jets fighter, designated USAF's XF-109 and USN's XF3L-1. It was designed as the same aircraft class as the F-104 and could fly at speeds around Mach 2. The XF-109 was powered by eight jet engines. Two were sat vertically behind the cockpit, and two were mounted horizontally in the tail. Two more pairs were located at the wing tips that could rotate, which gave lift when pointing upward in a vertical position and could then be rotated into a horizontal position for level flight. In 1960, Navy halted the funding as the jet engines schedule kept being delay. A year later, the Air Force also decided it was no longer interested in this concept. The program was cancelled at its mockup stage in 1961.
