President Donald Trump boasted during a press conference in May that the United States had a new missile. “I call it the ‘super-duper missile,’ and I heard the other night it is seventeen times faster than what they have right now when you take the fastest missile we have right now,” Trump said. Though he was rather scanty on details, the missile in question is likely the hypersonic AGM-183A ARRW, which stands for Air-Launched Rapid Response Weapon. Being hypersonic, it is fast—really fast.
In a controversial move, the United States Air Force opted for the AGM-183A ARRW over another hypersonic missile project, the HCSW on account of the former missile’s smaller, more compact size. An acquisition official with the Air Force that “the reason we went with ARRW was not that HCSW was bad, but ARRW is smaller,” it could be mated to both bombers and fighter jets, giving the service better munition flexibility. “We can carry twice as many on the B-52, and it’s possible it could be on the F-15,” the official elaborated.
The AGM-183A ARRW is a glide-boost type of system. Munitions of this type use a rocket motor base to propel them up to hypersonic speeds, at which point the rocket separates from the glide vehicle, and glides to its destination to deliver explosive payload.
Still, that does not mean that other hypersonic missiles are down and out. In a tweet, the assistant to the secretary of defense for public affairs clarified that the Department of Defense is “working on developing a range of hypersonic missiles to counter our adversaries,” a possible reassurance to companies currently working on hypersonic missiles that their efforts will not be in vain.
