At this point North Korea has hypersonic technology that the US does not.
Meanwhile, the USA has been working on hypersonic since the late 1990s, but 25 years later there is still no in-service weapons and nothig coming in the immediate future.
Crap, even worse than I though. As they DO NOT say in the US Brass (because it’s true): “Quantity has a quality of its own.”. Sure would be nice if our military was capable of KEEPING SHIPS OPERATING (along with other systems), even while commissioning new ones.
They do not have a hypersonic glide vehicle. Just booster on older rockets.
