In August 1999, major assembly began on a militarized 747-400 Freighter to be used as a platform for the U.S. Air Force’s Airborne Laser (ABL) program. It rolled out on Oct. 27, 2006, and was eventually designated YAL-1. Boeing was the prime contractor for ABL, which was designed to provide a speed-of-light capability to destroy all classes of ballistic missiles in their boost phase of flight. Boeing provided the modified aircraft and the battle management system and is the overall systems integrator. ABL partners were Northrop Grumman, which supplied the chemical oxygen iodine, or COIL, high-energy laser associated lasers, and Lockheed Martin, which provided the nose-mounted turret in addition to the beam control/fire control system. On Feb. 11, 2010, the flying test bed destroyed a ballistic missile off the coast of Southern California. The program was canceled in 2011, and in 2012, YAL-1 was flown to the U.S. Air Force “bone yard” near Pima, Ariz., to be scrapped.
