So it’s a missile that travels at 5x the speed of sound without leaving the atmosphere? What is its propulsion and how fast does it achieve hypersonic speed?
Honestly I don’t know.
If they exist, that would be classified.

At hypersonic speed, the propulsion system could be a ramjet, which is a shaped fuel reaction chamber where oxygen from the atmosphere is compressed, combined with fuel, and ignited. Picture a jet engine minus the turbine blades. To work, you need to boost the aircraft to hypersonic speed using a solid fuel booster or conventional jet engine.
