Back when Ukraine invasion kicked off there was a lot of puffing about Russia and Chinas hypersonic capabilities, fearmongering essentially. I was a nerd bout the X projects so i knew it was all smoke. When I would say that Russia or China can't even begin to touch US hypersonic tech, this is what I mean. The US has been working on hypersonic flight for decades, before China's economic boom, and while post soviet Russia was still a baby with a destroyed economy. I would be very surprised if the have anything anywhere close to what we have.

Aren't the Russian hypersonic missiles essentially just regular ballistic missiles? I remember reading something saying that calling them hypersonic was a stretch, and they have been intercepted by standard missile defense systems which actual hypersonic missiles wouldn't be.

I think they have gliding capabilities and can maneuver but they generally follow a predictable trajectory and thats why they are able to be shot down, because if they do maneuver they lose a stupid amount of range.
