The US Air Force's Airborne Laser platform successfully destroyed a ballistic missile this morning. It's the first time that a high-energy laser weapon has destroyed a target in flight, and the first time that any defensive system has destroyed a ballistic missile during the boost phase of flight. The laser weapon was developed by Northrop Grumman, the beam & fire control system by Lockheed Martin and the aircraft & integrated system by Boeing. The beam is emitted from the world's largest turret assembly, which is mounted at the nose of a modified 747. Last night's test was conducted off the coast of California. Although initially designed as a defensive system, the ABL, Advanced Tactical Laser and Laser Avenger are proving the concept and effectiveness of directed energy weapons.
