The U.S. Air Force says it carried out a successful test of a new type of hypersonic missile over the weekend. The Pentagon says a B-52 bomber off the coast of Southern California successfully test-fired an “Air-Launched Rapid Response Weapon” that reached five times the speed of sound. The test of the nuclear-capable missile follows similar tests by China and after Russian President Vladimir Putin said he’s deployed hypersonic missiles during Russia’s invasion of Ukraine.
