In July 1980 a "hot firing" test of the system was made being the first airborne test of the system. The flight took place near WSMR at 10,000 feet. A series of airborne systems tests were then made prior to extracting a beam from the ALL. In January 1981 a high-energy laser beam was generated inside the ALL, directed through the APT, and propagated in the air outside the aircraft; this was the first demonstration that the ALL components could work as a unified system and point to a target. 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.
