Assuming you mean supercavitation then it's been used on torpedoes and there have been tests done on larger underwater craft. Problem with it is that it's noisy. A submarine using supercavitation would be instantly detectable by any sonar system for hundreds of miles and the noise it generates would blind its own sonar.
Yes, I should have said supercavitation. I remember reading that it had been developed — or was in development — for torpedos, but it was still a dream for subs. I searched “how fast can a sub go” and learned that the Chinese claim to have developed a supercavitating sub that can go something like 4,000 mph! Sounds like an opium-pipe dream.
Sounds like the noise generated could be used to hid multiple launched torpedoes in a swarm type attack.
