Propulsion techniques vary across liquid and solid rocket engines, turbojet and turbofan engines plus some ramjet designs in supersonic weapons.
Most weapons are subsonic, but increasingly supersonic weapons of Russian origin are proliferating in Asia.
The supersonic Turayev ramjet-powered Kh-31A/MA 'Mini-Moskit' (Izdeliye 77 or AS-17 Krypton) is a radar guided anti-ship derivative of the Kh-31P originally designed as an anti-radiation missile to suppress NATO Patriot and IHawk batteries.
The heavyweight radar guided Raduga 3M-80, 3M- 82 and Kh-41 Moskit (SS-N- 22 Sunburn) are all variants of the same 4.5 tonne supersonic rocket-ramjet missile.
The Moskit is a supersonic sea-skimmer.

Visualization of a supersonic underexpanded jet by planar Rayleigh scattering [1989] 111
Freund, "An evaluation of linear instabil- ity waves as sources of sound in a supersonic turbulent jet," Phys.
Simultaneous visualization of the pressure and divergence of velocity (not shown) suggest that there are usually regions of high pressure at the origin of each Mach wave convecting at an appropriate supersonic velocity for the Mach angle, but as yet we have not identified consistent concrete events that spawn Mach waves.،Visualization of a supersonic underexpanded jet by planar Rayleigh scattering [1989] 111
