I heard that the super cavitation that allows such obscene underwater speeds is caused by a magnetically induced flow that isolates the missile with a
boundry layer . But this magnetic field precludes any kind of guidance system????
Also if a subsonar is blind once the sub goes faster than say 20kts how would this torp be selfguiding...unless its FO guided?

From my understanding, it works by using a thin layer of gas over the missle as a buffer between its self and the water.
During end game I believe it would slow down to seek its target.
One more thing - could this tech be used to make subs cruise at near mach 1 speeds? Imagine that!
