Japan Cruiser
A training cruiser with a hybrid propulsion system and wide-ranging armament: 140 mm main battery guns, dual-purpose 127 mm guns, 25 mm automatic AA guns, 533 mm torpedoes, and a catapult with a seaplane. Such variety was necessary for cadet training. During World War II, Katori was used primarily as a command ship for the 6th Fleet. On February 18, 1944, Katori was sunk by artillery fire from battleship Iowa during the evacuation of the Japanese from the Truk Atoll.
