How Real Is The Threat Of Laser Weapons: "The ALTB project is one of the MDA's most ambitious and long-term programs. Washington launched its initial research in this sphere in the 1970s. At that time, an NKC-135-ALL aircraft, a modified version of the KC-135 Stratotanker, was built and used as an airborne laboratory.
United Technologies built a 10-ton, 04-0.5-MWt CO2 laser system for the program. The NKC-135-ALL was involved in a series of tests in the late 1970s and the early 1980s. Although the tests proved that a laser weapon was feasible, it had a range of just a few kilometers and therefore lacked any military prospects.
In 1985, a laser weapon used in ground tests heated up the stationary fuel tank of a Titan-1 intercontinental ballistic missile simulating a Soviet ICBM a thousand meters away causing it to explode."
