US Air Force Abandons Troubled Hypersonic Missile Program.

The US Air Force will not purchase Lockheed Martin's hypersonic AGM-183A Air-launched Rapid Response Weapon (ARRW) after the prototyping phase ends due to problems during testing. However, the service will complete the ARRW program's last two all-up round test flights to collect data to help with future hypersonic programs. The Air Force still wants to carry out two more ARRW tests with its remaining prototypes, but it is more committed to its other major hypersonic weapon program, the Hypersonic Attack Cruise Missile.
