Edwards Air Force Base An Air Force AGM-183A ARRW hypersonic weapon test ended in failure on Monday. The booster test vehicle carried by a B-52 bomber was unable to complete the launch sequence. The ARRW is expected to be the first air-launched hypersonic weapon in the US arsenal. A US Air Force bomber tried and failed to launch a test missile for a new hypersonic weapon during a long-awaited first flight test Monday. The Air Force said in a statement that it suffered "a setback in demonstrating its progress in hypersonic weapons on April 5 when its first booster vehicle flight test encountered an issue on the aircraft and did not launch."
