Japanese battleship Ise
Despite the expensive reconstruction, the ship was considered obsolete by the eve of the Pacific War, and did not see significant action in the early years of the war. Following the loss of most of the IJN's large aircraft carriers during the Battle of Midway in mid-1942, she was rebuilt with a flight deck replacing the rear pair of gun turrets to give her the ability to operate an air group of floatplanes; lack of aircraft and qualified pilots meant that "Ise" never actually operated her aircraft in combat. She participated in the Battle of Cape Engaño in late 1944, where she decoyed the American carrier fleet supporting the invasion of Leyte away from the landing beaches. Afterwards the ship was transferred to Southeast Asia; in early 1945 "Ise" participated in Operation Kita, where she transported petrol and other strategic materials to Japan. The ship was then reduced to reserve until she was sunk during American airstrikes in July. After the war "Ise" was scrapped in 1946–1947.

To provide distant support for the 1st Air Fleet attacking Pearl Harbor on 8 December, the division, reinforced by the battleships and and the light carrier , sortied from Hashirajima to the Bonin Islands and returned six days later. "Ise" had a minor refit at the Kure Naval Arsenal in 19–25 February 1942. Together with the rest of the division, she pursued, but did not catch, the American carrier force that had launched the Doolittle Raid on 18 April. On 11 May "Ise" had an accident which flooded her No. 2 engine room. While under repair, the ship was fitted with one of the first experimental Type 21 early-warning radar sets in the IJN, but it was removed shortly afterwards.
