What happens when you break the sound barrier under water?

In incompressible fluids like water, this doesn't necessarily work out the same way. In water, the dynamics tend to be far more violent, even well below the speed of sound. In particular, you will readily end up with cavitation bubbles. As already said by Acid Jazz, this allows for a rather remarkable mode of underwater motion, which is completely unlike anything you get in air.

tl;dr, the sound barrier isn't really relevant under water, because stranger effects turn up before you ever get close to it.

However, it would still be relevant if you could manage to keep the pressure pertubations small enough even close to the speed of sound. Actually, this is relevant for any supersonic motion under water, if you look at it on a big enough scale. For instance, an asteroid impact into the ocean does no doubt cause a sonic cone quite analogous to the one generated by supersonic aircraft.

Man, I'm gettin' horny.

How the fock can a sub go the speed of sound in water?

It's got a reservoir tip.

I think they're a month and a half early. They were supposed to release this information on April 1st

 Neptune asks Aquaaman to pull his finger and gives a new meaning to tsunami.

The speed of sound in air is 740 mph

The speed of sound in seawater is 1449 mph to 1563 mph depending on temperature.

Yeah but will it have any good sides.

I'm trying to wrap my head around the strategic advantage of it? Being able to respond and move to an area where needed more rapidly, I guess

Out running torpedoes and depth charges seems good.

What if it hits a whale going full speed?

My googling says the speed of sound in salt water is about 1500 meters per second, which is 3345 miles per hour.

I'm sure they mean it goes faster than the speed of sound in air.

You're correct about the speed in mph in saltwater, I typed the wrong units and/or forgot to convert to mph.  That (speed of sound in air) would not produce a supersonic submarine then, so I don't think that's what they mean. The Chinese sub is supposed to be developed to go 4000 mph (from the link I posted).
