“ A 125mm gun has a muzzle velocity of 1800f/s and that is hyper-sonic.”
I am pretty sure that is “only” supersonic, which means it is faster than sound. I have read that hypersonic means 5x the speed of sound. There have been reports that the new Russian missile goes up to 12x the speed of sound.

1800f’/s (4,000 mph) is the bottom of hypersonic speed curve.

Sorry I am not buying any of this. Nothing man made traveling at 12x SoS could be maneuvered. The slightest change in attitude and thing would go out of control and turn into a molten pile of crap.

Hypersonic is the speed at which the air ionizes and turns into plasma, and not just a regular shock wave. It's normally about Mach 5, but varies based on air temp, composition, etc.
