Theoretically, the development could allow a submarine to travel faster than the speed of sound without producing the mechanical noise vibration that usually gives away its location, according to the researchers.
faster than the speed of sound. that can't be right, right?
that said, amazing tech. also I guess if you tried to produce a sonic boom underwater you'd have to go way faster than in air right? would supercavitation tear your vessel apart before then?

Maybe they mean faster than the air speed of sound but still less than the underwater speed (which is a huge margin, it turns out, 340 vs 1500 m/s)
I thought even that would be way too fast but it seems like it's totally possible. Had no idea! https://en.wikipedia.org/wiki/VA-111_Shkval
Russia already makes supercavitating torpedoes, so should be possible to do it for subs as well https://en.wikipedia.org/wiki/VA-111_Shkval
