The XF-104, Lockheed Model L-246, was designed by Kelly Johnson of the famed "Skunk Works." Two aircraft (S/N 53-7786 and 53-7787) were built. The first flight was on March 5, 1954. Powered by the Wright J65, the XF-104 flew as fast as Mach 1.7.

Seventeen YF-104A service test aircraft (S/N 55-2955 to 2971) were built with the improved General Electric J79 turbojet. The YF-104A (55-2955) exceeded Mach 2 on Feb. 28, 1956. The pre-production Block 1 F-104As (S/N 56-730 to 736), along with the YF-104As, were retrofitted during testing to solve various problems revealed during the program including pitch-up, low speed handling and engine problems.

Aircraft description from T.O. 1F-104A-1 - F-104 aircraft are high-performance day and night fighters powered by an axial-flow, turbojet engine with afterburner. F-104A and C are single place aircraft, built by Lockheed Aircraft Corporation, are designed for cruise at high subsonic speeds and combat at high supersonic speeds. Notable features of the aircraft include extremely thin flight surfaces, short straight wings with negative dihedral, irreversible hydraulically powered ailerons, and a controllable horizontal stabilizer. The wings, with leading and trailing edge flaps, have a boundary layer control system which is used in conjunction with the trailing edge flap to reduce landing speeds. A drag chute is installed to reduce the landing roll.

The National Museum of the United States Air Force has an F-104C on display in its Cold War Gallery and an F-104A on display in front of the museum complex.
