Settsu was a Kawachi-class battleship built for the Imperial Japanese Navy. Launched on 30 March 1911, she was completed on 1 July 1912. During the First World War, Settsu and her sister Kawachi bombarded German positions at Qingdao during the siege of Qingdao in 1914, but saw no other combat.
After World War One, Saeetsu was placed in reserve in 1919 and disarmed in 1922 in compliance with the Washington Naval Treaty. In 1924 she was converted to a target ship, a role she undertook until 1945.
At the start of the Second World War, Settsu was deployed to the Philippines, where she simulated the radio traffic of the six main fleet carriers, as well as two light carriers in order to deceive Allied intelligence as to their whereabouts.
Settsu was badly damaged by S Navy aircraft in July 1945. Subsequently refloated she was scrapped in 1946-47.
Launched in 1914 and commissioned in 1915, Fuso was the lead ship of her class of dreadnought battleships built for the Imperial Japanese Navy. Fuso played no part in World War One, instead patrolling the coast off China. She underwent extensive rebuilds from 1930–1935 and 1937–1941 with improvements to her armor and propulsion machinery and a rebuilt superstructure in the pagoda mast style.
Due to her age, Fuso was used primarily in auxiliary roles early in the Second World War. At the Battle of Leyte Gulf, Fusō was part of Vice-Admiral Shōji Nishimura’s Southern Force. On the morning of 24 October1944, Fuso was attacked by aircraft from the USS Enterprise and hit by two bombs. The first destroyed her aircraft catapult and floatplanes, while a second hit near Turret No. 2 and penetrated the decks, killing everyone in No. 1 secondary battery; the ship began to list 2 degrees to starboard.
During the subsequent night action of the Battle of Surigao Strait, Fuso was hit by one or two torpedoes and sank with 1,620 casualties.
