The Kawachi class (河内型戦艦, Kawachi-gata senkan) was a two-ship class of dreadnought battleships built for the Imperial Japanese Navy (IJN) in the first decade of the 20th century. Both ships bombarded German fortifications at Qingdao during the siege of Qingdao in 1914, but saw no other combat in World War I. Kawachi sank in 1918 after an explosion in her ammunition magazine with the loss of over 600 officers and crewmen. Settsu was disarmed in 1922 and converted into a target ship two years later to meet the terms of the Washington Naval Treaty and served until she was sunk in 1945 by American carrier aircraft. The ship was refloated after the war and scrapped in 1946–1947.
