The Boeing YAL-1 Airborne Laser Testbed (formerly Airborne Laser) weapons system was a megawatt-class chemical oxygen iodine laser (COIL) mounted inside a modified Boeing 747-400F. It is primarily designed as a missile defense system to destroy tactical ballistic missiles (TBMs), while in boost phase. The aircraft was designated YAL-1A in 2004 by the U.S. Department of Defense.[1]
The YAL-1 with a low-power laser was test-fired in flight at an airborne target in 2007.[2] A high-energy laser was used to intercept a test target in January 2010,[3] and the following month, successfully destroyed two test missiles.[4] Funding for the program was cut in 2010 and the program was canceled in December 2011.[5] It made its final flight on February 14, 2012 to Davis–Monthan Air Force Base in Tucson, Arizona to be prepared and kept in storage at the "Boneyard" by the 309th
