The Boeing-led Airborne Laser team has announced the successful completion of a series of tests involving its high-energy laser at the Systems Integration Lab at Edwards Air Force Base,
During this test series, lasing duration and power were demonstrated at levels suitable for the destruction of multiple classes of ballistic missiles.
Airborne Laser's (ABL) megawatt-class Chemical Oxygen Iodine Laser (COIL) is designed and built by Northrop Grumman Corporation. Lasing tests included more than 70 separate lasing events. The laser has been operated at simulated altitude, and achieved steady state operations under full optical control.
In July 2005, the ABL team completed flight testing of the system's passive mission payload at Edwards Air Force Base. During those tests, the team demonstrated the stability and alignment of the two Beam Control and Fire Control optical benches with the turret. That test also demonstrated the system's pointing and vibration control functions, as well as its ability to acquire targets as directed by the battle management segment.
With the completion of the above milestones for 2005, the program now proceeds to integrated systems testing. The ABL YAL-1A aircraft has moved to Boeing's
During active testing, the kilowatt-class illuminator lasers will be integrated and tested to demonstrate target acquisition, fine tracking, pointing and atmospheric compensation. Upon completion of active testing, the YAL-1 will return to Edwards Air Force Base for installation of the High Energy Laser, which will be removed from the System Integration Laboratory. This will be followed by extensive weapon systems testing on the aircraft, both ground and flight.
"This is a major technological achievement for the Airborne Laser program," said Pat Shanahan, vice president and general manager of Boeing Missile Defense Systems. "Proving the capability of this laser to operate at lethal levels of power and duration moves the system a major step closer to becoming a vital component of the nation's boost phase defence against a ballistic missile threat."
The ABL consists of a megawatt-class, high-energy Chemical Oxygen Iodine Laser placed on a Boeing 747-400 aircraft. In operation, the ABL's sensor system will autonomously detect and track an enemy's boosting missile, determine its position and destroy it with the high-energy laser. The ABL's sensor system also identifies the launch location and predicts the impact location, which is communicated to other elements in the missile defence architecture.
