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.
