"Hypersonic weapons move faster than anything currently being used, giving adversaries far less time to react, and they provide a much harder target to counteract with interceptors"
DOD News, "Hypersonics Testing Accelerates"
"New tanks, military satellites, rockets and missiles, even a hypersonic missile that goes 17 times faster than the fastest missile currently available in the world."
