Mutsu was a Nagato-class battleship, and one of the handful of ships carrying 16-inch guns under the Washington Naval Treaty. (Alongside others such as the West Virginia and the Nelson.)

In 1943 one of her magazines detonated while at anchor, completely destroying her. An investigation determined it to be sabotage by a Japanese sailor.
