I thought it was speeds of mach 9, or 10. The Russians hit around 9000mph on their launch claiming it could hit 10000 mph. The warhead also uses glide technology. Or I thought it was in the excess of mach 7. The fastest things on the planet currently. They have faster seen missile defense advancing into lasers.

Basically a cruise, but quite a bit faster, carrying a nuclear payload, and equipped fueled, fitted onto planes and ships possibly even drones.

When you are talking hypersonic, basically Moscow to London, in what, all of 10 minutes?

Here North Korea is trying to boost propaganda, suggesting it can evade Thaad and other defenses. Also trying to get one up on the South Korean landmark launch, a type of cruise being more than capable of penetrating defenses. Curiously it isn't hypersonic. Unless they have been outfitted by somebody else.
