"2 hits on a battleship isn't enough"
Really?
Considering the majority of battleships in the Royal Navy are refit WW1 types, are you essentially saying they should be magically running a modern WW2 armor and flooding control/protection schema in this game? Why exactly?
"On 25 November 1941, while steaming to cover an attack on Italian convoys,
Barham was hit by three torpedoes from the German submarine
U-331, commanded by Lieutenant
Hans-Dietrich von Tiesenhausen. The torpedoes were fired from a range of only 750 yards providing no time for evasive action, and struck so closely together as to throw up a single massive water column. As she rolled over to port, her magazines exploded and the ship quickly sank with the loss of over two thirds of her crew."
Honestly... two torps would have done the same, it'd just have taken a little longer to roll. Maybe had the ship been sitting still it would have been different, but for moving - two torps is fine.
