The US had hypersonic aircraft and missiles long before any other country. Go look up the X43 and see what year that aircraft was flying. You really think the US just put that technology on the shelf and ignored it or do you think maybe, maybe they don't advertise the technology that has been developed.

Face it Putin, we are so far ahead of everyone else in the world in terms of technology it's not even a competition except for second place. Second place is also the place that China doesn't hold.
