The U.S. Air Force’s scramjet-powered Hypersonic Attack Cruise Missile (HACM) has finally reached the flight test phase, with at least one “release” having been carried out so far over a range in Australia. HACM has suffered significant delays, and the Air Force has taken the risky step of scaling back overall testing plans to try to keep the program on schedule. The stated goal is to be able to make a decision to start rapidly acquiring HACMs in 2027. https://www.twz.com/air/first-release-of-usafs-new-hacm-hypersonic-cruise-missile-has-happened-over-a-test-range-in-australia
