Yes, but torpedoes are meant to blow up after firing. Ships aren't. The torpedoes don't have to withstand 60 years of supercavitation damage (unlike ship propellers do, which already can't, and need frequent maintenance and replacement) (also this has nothing to do with supercavitation, it's just a regular bubbler at the bottom of the ship that lets air rush to the surface around the hull)
