WASHINGTON — The U.S. Air Force conducted a second consecutive successful flight of Lockheed Martin’s AGM-183A Air-launched Rapid Response Weapon, marking the end of the hypersonic program’s booster test phase. The test took place July 12 and the hypersonic missile, which flew from a B-52H Stratofortress, met primary and secondary objectives, the service said in a July 13 statement. With the completion of the booster series, ARRW will begin all-up-round testing later this year. Brig. Gen. Heath
