Just thought I'd like to mention that I think it was about 3 or 4 years ago that the americans had an expirimental supercavitation weapon in the works. DARPA is into all sorts of intereting stuff that we'll probably never hear about. The russians plan for shkval-II seams to make the most sense though. I forget where I heard about it but apparently, the russians want to make a next-generation super-cavitating torpedo that will supercavitate towards its target at 300 or so knots, then slow down to speeds simular to a normal torpedo (say 30-50 knots) and aquire its target on active sonar, then speed up again and super cavitate to its target. While not fool-proof (I bet active countermeasures could conceviably throw it off) this makes a lot more sense that just shooting an unguided 300 knot supercavitating bullet.
