A U.S. hypersonic drone aircraft abruptly fell out of communication during a flight test on Wednesday, the Associated Press reported (see GSN, Aug. 10).

The Hypersonic Technology Vehicle-2 is one system being considered to provide the United States with the "prompt global strike" capability to deliver non-nuclear warheads to any location in the world within an hour (Associated Press/Washington Post, Aug. 11).

"Range assets ... lost telemetry" after the vehicle detached from a Minotaur 4 rocket and the test entered its glide stage, the Defense Advanced Research Projects Agency said (U.S. Defense Advanced Research Projects Agency release, Aug. 11). The rocket was fired from Vandenberg Air Force Base in California, AP reported.

The glider failed in its first trial flight, conducted in April 2010 (see GSN, Aug. 19, 2010; Associated Press).
