 The United States Navy tested the F-117 in 1984 but determined it was not suitable for carrier use.In the early 1990s, Lockheed proposed an upgraded, carrier-capable variant of the F-117 dubbed the "Seahawk" to the Navy as an alternative to the canceled A/F-X program.The unsolicited proposal was received poorly by the Department of Defense, which had little interest in the single mission capabilities of such an aircraft, particularly as it would take money away from the Joint Advanced Strike Technology program, which evolved into the Joint Strike Fighter.
