You needed one more fish! The Nagato I sent to the bottom took 9 torpedos, then slowly capsized and sank. This battleship was sunk after two separate attacks several days apart, just happened to run into the TF twice.
A Kongo took less, but had already been damaged running aground.
We also sank a Shokaku class carrier after hitting it with 20 torpedos in 4 separate attacks (7 duds) before she went down. Tough old girl
Have aslo sunk several heavy cruisers and a few light cruisers too, but I don't think that's what you're after.
