Lockheed Martin's Hypersonic Air-breathing Weapon Concept (HAWC) completed a free flight test in mid-March, the US Defense Advanced Research Projects Agency (DARPA) announced on 5 April.

The weapon was released from a Boeing B-52H Stratofortress bomber, a DARPA spokesperson told Janes. Then its Aerojet Rocketdyne supersonic combustion ramjet (scramjet) engine ignited and sent the prototype weapon to more than five times the speed of sound (Mach 5) for “an extended period of time”, according to the agency. It hit altitudes of more than 65,000 ft and flew for more than 300 n miles.

A Pentagon official told Janes that the announcement of Lockheed Martin's HAWC test was delayed so as to avoid provocations amid Russia's invasion of Ukraine.

The HAWC's engine uses air captured from the atmosphere for propulsion, according to DARPA, giving it speed and manoeuvrability that enable “both evasion of defences and quick strikes”. The weapon can use its kinetic energy, as opposed to a high-explosive payload, to destroy targets.
