I was wondering if any missile or torpedo tests have been done against modern thick steel. Polar Class 3 ship steel is 48mm thick. Obviously it's not thick everywhere, and not designed against missile strikes. But it's the closest I can think of to any ship having any thickness or steel toughness remotely approaching a battleship.

What about submarine pressure hulls? A lot of torpedos are designed to sink submarines, & I think that 48mm should be within the range they're designed to breach.

At least one cruise missile has been tested against a submarine, & did this -

The warhead is two stage. The first stage punched a hole through the hull, which the second stage flew through before exploding inside. I don't know the thickness of a Kilo-class's hull, but I expect it to be significantly thicker than that of a merchant ship, or destroyer.
