The highlight of the ALL program occurred in May 1983, over the Naval Weapons Center Range at China Lake, California, where the laser was combined with a sophisticated pointer and tracker to negate, or disable, five AIM-9 "Sidewinder" missiles. While the missiles did not fall from the sky in pieces, they were disabled to the point that they could no longer locate, track, and strike their target. Despite its success, weapons planners ignored the ALL because its missions had been categorized as "proof of concept" rather than demonstrations of a viable war tool. The ALL aircraft was retired in 1984 and stored in hangar 760 at Kirtland. Four years later it took its final flight to Wright Patterson AFB, where it is now on display at the United States Air Force Museum. About a decade later, after the Gulf War, the concept of an anti-missile laser was revitalized in the Boeing YAL-1 airborne laser program. Air Force Test and Evaluation Center In 1974, the Air Force Test and Evaluation Center (AFTEC) was organized at KAFB "to direct and oversee operational testing of emerging Air Force aircraft and systems". The purpose of AFTEC was to answer questions about how safe, effective, reliable, maintainable, compatible, and logistically supportable new USAF systems would be for acquisition purposes. The F-16 Falcon fighter and the BGM-109 Tomahawk cruise missile were among the weapons the center tested in the 1970s, and the Kirtland Base Information Resources and Economic Impact statement of FY 1984 reported that AFTEC was then "evaluating more than 90 major systems. Among them are the Peacemaker missile, the HH-60 helicopter, a new version of the F-15 advanced medium range air-to-air missile, the Maverick air-to-ground missile, TRI-TAC multiservice communication system and the B-1 bomber". Due to budget restrictions and reorganization, the Special Weapons Center was disestablished during 1976. Its responsibilities as Kirtland AFB's landlord’ were transferred to Contract Management Division, and a new support organization, the 4900th Air Base Wing, was created to discharge those responsibilities. 1550th Combat Crew Training Wing In 1976, as these organizational changes were being made, the Aerospace Rescue and Recovery Service moved its 1550th Aircrew Training and Test Wing (later becoming the 1550th Combat Crew Training Wing) to Kirtland AFB from Hill AFB, Utah. That unit's helicopter and fixed wing training brought regular flight operations to Kirtland in addition to the usual support provided for transient military aircraft. The
