WThe AAM-N-10 Eagle was a long-range air-to-air missile developed by the Bendix Corporation for use by the United States Navy. Intended for carriage by the Douglas F6D Missileer fleet defense fighter, the Eagle program was cancelled before testing could begin, but the lessons learned were used in the development of the AIM-54 Phoenix missile.
WThe AIM-152 AAAM was a long-range air-to-air missile developed by the United States. The program went through a protracted development stage but was never adopted by the United States Navy, due to the ending of the Cold War and the reduction in threat of its perceived primary target, Soviet supersonic bombers. Development was cancelled in 1992.
WThe Advanced Strategic Air-Launched Missile (ASALM) was a medium-range strategic missile program, developed in the late 1970s for the United States Air Force. Intended for use in both the air-to-surface and anti-AWACS roles, the missile's development reached the stage of propulsion-system tests before being cancelled in 1980.
WHave Dash was a program conducted by the United States Air Force for the development of a stealthy air-to-air missile. Although the Have Dash II missile appears to have been flight tested, the results of the project remain classified and no production is believed to have been undertaken.
WThe JB-3 Tiamat, also designated MX-570, was an early air-to-air missile developed by Hughes Aircraft for the United States Army Air Forces during World War II. Regarded as a purely experimental vehicle, test launches took place for several years before the program was terminated.
WThe KA2N Gorgon IIA – also designated KU2N, CTV-4, and CTV-N-4 – was an air-to-air missile developed by the United States Navy near the end of World War II. Proving a failure in its designed role, it was repurposed as an experimental testbed for missile technology.
WThe Gorgon III – given the military designations KA3N, KU3N, CTV-N-6 and RTV-N-4 – was a rocket-powered air-to-air missile developed by the United States Navy near the end of World War II. With the end of the war, the program was changed to that of a research vehicle for missile control systems; both single and twin-rocket-powered versions were built and tested.
WThe Gorgon missile family was a series of experimental air-to-air, air-to-surface, and surface-to-surface missiles developed by the United States Navy's Naval Aircraft Modification Unit between 1943 and 1953. The immaturity of the technology involved meant that none of the Gorgon missiles achieved operational service, however they were extensively used in the development of guided missile controls and guidance technologies.
