Hypersonic
From Conservapedia
A hypersonic missile can fly at Mach 5 (five times the speed of sound, 3,800 mph) or greater.
Ukraine Ministry of Defense claims a 25% interception rate for Russian hypersonic Kinzhal and Zircon missiles, but Ukrainian sources also indicate such interceptions require salvo firing all 32 launchers in a US-style Patriot missile battery to have any chance to shoot down a single hypersonic missile.
