A high-energy laser mounted on a US military aircraft has shot down a ballistic missile in the first successful test of the weapon, the US Missile Defense Agency said on Friday.The experiment -- evoking a scene out of a science fiction film -- was carried out off the central California coast at Point Mugu Naval Air Warfare Center at 8:44 pm Thursday Pacific time (0444 GMT), the agency said in a statement.
"The Missile Defense Agency demonstrated the potential use of directed energy to defend against ballistic missiles when the Airborne Laser Testbed (ALTB) successfully destroyed a boosting ballistic missile," it said.
The laser, mounted on a turret on the nose of a modified 747 aircraft, is designed to knock out an enemy missile by burning a hole in its side.
The project has been touted as potentially revolutionary, as the lasers are supposed to destroy ballistic missiles just after launch, when the missiles are moving at a slower speed on a predictable path.
The test could provide a boost to the five billion dollar program that has faced technical problems and been scaled back from initial plans that called for building a fleet of seven laser-equipped aircraft.
Last year Defense Secretary Robert Gates cancelled funds for a second prototype aircraft and called for more research to refine the weapon. He said the proposed role for the laser remained "highly questionable" amid questions about its cost and effectiveness.
