DARPA and its U.S. Air Force partner recently completed a free flight test of the Lockheed Martin version of the Hypersonic Air-breathing Weapon Concept (HAWC). The vehicle, after release from a carrier aircraft, was boosted to its Aerojet Rocketdyne scramjet engine ignition envelope. From there, it quickly accelerated to and maintained cruise faster than Mach 5 (five times the speed of sound) for an extended period of time. The vehicle reached altitudes greater than 65,000 feet and flew for more than 300 nautical miles.

This is the second successful flight in DARPA's HAWC program. Last September, a different vehicle configuration from another contractor team also reached hypersonic flight.

"This Lockheed Martin HAWC flight test successfully demonstrated a second design that will allow our warfighters to competitively select the right capabilities to dominate the battlefield," said Andrew "Tippy" Knoedler, HAWC program manager in DARPA's Tactical Technology Office. "These achievements increase the level of technical maturity for transitioning HAWC to a service program of record."

Air-breathing vehicles utilize air captured from the atmosphere to achieve sustained propulsion. The speed and maneuverability of such hypersonic cruise missiles allow both evasion of defenses and quick strikes. Their kinetic energy can effectively destroy targets even without high explosives.

"We are still analyzing flight test data, but are confident that we will provide the U.S. Air Force and Navy with excellent options to diversify the technology available for their future missions," said Knoedler.

US tests hypersonic missile
Washington (AFP) April 5, 2022
The US military announced Tuesday a new test of a hypersonic missile, as Pentagon officials seek to match or get ahead of China's and Russia's advances in the cutting-edge strategic weapons technology. The Defense Advanced Research Projects Agency (DARPA) said it had recently completed a free flight test of an aircraft-launched hypersonic missile that maintained a speed of more than Mach 5, or five times the speed of sound (at least 3,800 miles per hour, or 6,100 kilometers per hour). The missil ... read more
