HTC-2 Hypersonic Vehicle Fails Test

For the second time in a row, the Pentagon has lost contact with an experimental hypersonic vehicle over the Pacific, just minutes after it was launched from space.

The flight of the Falcon Hypersonic Technology Vehicle 2 was hotly anticipated in military and aerospace circles. The HTV-2 was supposed to ride on the back of a rocket to the edge of space, where it would separate and scream through the atmosphere at 13,000 mph before splashing into the Pacific Ocean, about 4,100 miles and 30 minutes later.

If the flight worked, it’d show how missiles of this shape and flight pattern could strike targets halfway around the world almost instantly. And that would be a major step forward in the Pentagon’s “Prompt Global Strike” plan to attack foes anywhere on the globe in less than an hour. For now, however, those hopes have been dashed.
