During WWII most Japanese Naval vessels were sunk by aircraft attacking with bombs and/or torpedoes. As the war progressed, the Navy modified the bomb type, size and fuze settings to maximize the likelihood of ship sinking. The type of target ship had a strong influence on these attack tactics. Torpedo attacks were also modified. The standard anvil type of attack was abandoned and the torpedoes running depth was set lower to 4 feet above the ships keel.
