The 24.5" Mark I torpedo was a British torpedo carried only on Nelson-class battleships. This was the type of torpedo that HMS Rodney fired at the German battleship Bismarck, "the only known occasion that a battleship fired torpedoes at an enemy battleship."[1]
This torpedo design was the inspiration for the Japanese Type 93 'Long Lance' torpedoes.[citation needed]
