WASHINGTON -- The failure of an interceptor missile to launch during a December test of the Pentagon's soon-to-be-activated missile defense system was caused by a "minor glitch" in its computer software, and the setback will not delay future testing, a senior official said Wednesday.
It was the first time the booster rocket was to be tested with a new and improved "kill vehicle," the device atop the rocket that uses computer codes and sensors to guide itself into the path of an incoming enemy missile. The device "kills" the target by colliding with it.
Air Force Lt. Gen. Henry A. Obering, director of the Missile Defense Agency, said the Dec. 15 test will be redone in mid-February, and additional tests in April, July and September will proceed as planned.
In the meantime, the eight missile interceptors that are now in underground silos in Alaska and California -- while not yet kept ready for use around the clock -- are capable of being activated for use against an actual missile attack against the United States, Obering told reporters.
