A recent propaganda video released by the Chinese military has brought one of the country's most advanced and threatening technologies back to the fore—hypersonic weaponry.
Hypersonic weapons travel at incredible speed and—unlike even the most advanced ballistic missiles—can maneuver in flight. This gives the weapons enormous range and makes them much harder to track and stop.
The U.S., Russia and China are all investing heavily in hypersonic technologies. However, the Pentagon has been the slowest to jump on the bandwagon and military chiefs are warning that the U.S. could be left behind by its authoritarian adversaries, at least when it comes to nuclear-capable hypersonics.
