Japanese Light Cruiser Ōyodo
Ōyodo was the last light cruiser completed for the Imperial Japanese Navy during the Second World War, representing an unusual departure from earlier Japanese cruiser practice. Rather than serving mainly as a destroyer flotilla leader or torpedo-armed night-fighting ship, she was designed as a command cruiser for submarine operations. Japanese planners expected her floatplanes to locate enemy forces, then pass information to submarine squadrons.
Laid down at Kure Naval Arsenal on 14 February 1941, Ōyodo was launched on 2 April 1942 and commissioned on 28 February 1943. By then, however, the war had moved beyond the concept that shaped her design. Allied air power, radar, and the changing balance in the Pacific made her intended submarine-command role far less practical.
Her layout reflected that specialised purpose. Ōyodo carried two triple 155 mm gun turrets forward, leaving much of the stern for aircraft facilities. She was intended to operate several Kawanishi E15K Shiun reconnaissance floatplanes, although that aircraft proved unsuccessful. In service, she instead carried more conventional Aichi E13A “Jake” floatplanes. She also mounted strong 100 mm dual-purpose anti-aircraft guns, but like many Japanese warships, she needed more light anti-aircraft protection.
During 1943, Ōyodo worked as a transport and fleet escort. In 1944 she was converted into a Combined Fleet flagship, with her large aircraft hangar adapted for staff and communications use. She later took part in the Battle off Cape Engaño during the Leyte campaign, escorting Japan’s carrier decoy force under Admiral Jisaburō Ozawa.
Early in 1945, Ōyodo participated in Operation Kita, helping bring valuable fuel and materials back from Singapore. She survived that dangerous voyage but not the final months of the war. American carrier aircraft attacked her at Kure, and on 28 July 1945 she capsized in shallow water. After the war, the wreck was raised and scrapped.
