The Defense Advanced Research Projects Agency has announced the successful free flight test of an air-breathing hypersonic cruise missile demonstrator developed by Raytheon and Northrop Grumman. This comes more than a year after the announcement of successful captive-carry tests of this weapon, as well as a competing design from Lockheed Martin, as part of the Hypersonic Air-breathing Weapon Concept program, or HAWC.

The announcement of this test of the Raytheon/Northrop Grumman missile came earlier today in a press release, but the Defense Advanced Research Projects Agency (DARPA), working together with the U.S. Air Force, conducted it last week. The U.S. Navy was also involved in the test. DARPA’s official statement does not provide any update on any similar progress on the Lockheed Martin design.
