A rendition of the Falcon Hypersonic Technology Vehicle 2 (HTV-2) 2 / 2. DARPA has launched an unmanned hypersonic gliding vehicle that can reach speeds up to Mach 20 (13,000mph).

Following an extensive seven-month analysis of data collected from the Aug. 11, 2011, second flight of DARPA’s Hypersonic Technology Vehicle (HTV-2), an independent engineering review board (ERB) ...

This would make coast to coast commuting a breeze. The U.S. military conducted a test of a new hypersonic aircraft Thursday that goes so fast it could fly from New York to Los Angeles in 12 minutes… ...

Hypersonic aircraft: An article in the Aug. 12 Business section about the failure of a test of the Falcon Hypersonic Technology Vehicle 2 misidentified a former Air Force officer and expert in ...

Launched from Vandenberg Air Force Base, California, the Falcon Hypersonic Technology Vehicle 2 (HTV-2) was expected to travel westward for about 30 minutes before plunging into the.

After the 2011 failed test of the long-range Hypersonic Technology Vehicle 2, or HTV-2, the United States largely shifted ...

An unmanned hypersonic glider likely aborted its 13,000-mph flight over the Pacific Ocean last summer because unexpectedly large sections of its skin peeled off, the U.S. Defense Advanced Research ...

A further threefold increase in the speed—from Mach 5 to Mach 15—would increase the heating by an additional factor of nearly 30. This intense heating led to the failure of the last test of the US ...
