Americans pursuit Russians in hypersonic weapons

The attempts by the U.S. Navy were somewhat different from those applied to another U.S. Navy rocket weapons. First, a launcher was used, which was installed: not on 1 of the many rocket ranges, but again at Cape Canaveral Space Force Station, Florida. Secondly, the Americans tested a hypersonic rocket that is “cold-fired” and so its launch engine started after the rocket was thrown into the air.
