Supersonic depleted uranium perpetrator going straight down would punch a hole clean thru.
Davy Jones does the rest.
You would think that would work but these ships have all kinds of compartmentalization and quick-response repair crews. And that’s an expensive hole. IMO, nothing beats a torpedo blowing up under a ship, cavitating the water under the middle of the ship and essentially letting gravity break the ship in half down the middle. No ship is strong enough to survive that.
