On Wednesday, the US Air Force confirmed that it had “successfully tested” its Air-Launched Rapid Response Weapon (ARRW) rocket on Tuesday, off the coast of California. The US has tested two Lockheed Martin hypersonic missiles despite concerns that its geopolitical rivals, Russia and China, have developed better hypersonic weapons.

On July 12, the US States Air Force (USAF) completed the booster test program by flying one last demonstration flight with its Lockheed Martin AGM-183A Air-Launched Rapid Response Weapon (ARRW) booster. Janes indicated in a report that the service provider announced on July 13 that it was “ready” to begin “all-up-round testing” later this year.

During the ARRW test, the launcher was lifted into the air beneath the wing of a B-52H before it was released into space. In earlier trials, the weapon did not separate from the aircraft.

“This second, successful test demonstrates ARRW’s ability to reach and withstand operational hypersonic speeds, collect crucial data for use in further flight tests, and validate safe separation from the aircraft,” Lockheed said.
