Although originally developed for the USN and a competitor to the USAF AIM-4 Falcon, the Sidewinder was subsequently introduced into USAF service when DoD directed that the F-4 Phantom be adopted by the USAF. The Air Force originally borrowed F-4B model Phantoms, which were equipped with AIM-9B Sidewinders as the short-range armament. The first production USAF Phantoms were the F-4C model, which carried the AIM-9B Sidewinder. The Air Force opted to carry only AIM-4 Falcon on their F-4D model Phantoms introduced to Vietnam service in 1967, but disappointment with combat use of the Falcon led to a crash effort to reconfigure the F-4D for Sidewinder carriage. The USAF nomenclature for the Sidewinder was the GAR-8 (later AIM-9E). During the 1960s the USN and USAF pursued their own separate versions of the Sidewinder, but cost considerations later forced the development of common variants beginning with the AIM-9L.
