By Ilya Kramnik, The US carries on its hypersonic projects in a bid to create hypersonic weapons. The US Air Force's experimental X-51A Waverider could someday lead to weapons that would be able to strike targets anywhere in the world in as little time as one hour. The research is part of the Prompt Global Strike (PGS) program. But the Pentagon is not alone – Russia doesn’t stop its hypersonic military efforts either and has already implemented some of them.It should be noted, that new warheads are quite heavy and large, thus a ballistic missile is capable of carrying a single warhead only. This means greater anti-missile shield penetrating chances but a less efficient strike. Source: Voice of Russia.
