Unryu leaving Yokosuka, 16 July 1944.

Aircraft carrier Unryū (1944–1944), Amagi (1944–1945), Katsuragi (1944–1945), 17,480 tonnes. The design for these ships was based on the aircraft carrier Hiryū. The IJN planned to build 16 ships, however only 3 were completed and 2 almost completed (one of which was sunk as a target then salvaged and later scrapped) before the project was abandoned in favour of Shinano's construction. Unryū was sunk by the USS Redfish, Amagi capsized after air attacks and Katsuragi was the only heavy carrier to survive the war.

IJMS Taiho anchored in Tawi-Tawi, the Philippines, May 1944.

Aircraft carrier Taihō (1944–1944), 30,250 tonnes. A slight break from the traditional Japanese carrier designs, Taiho was a heavily armoured carrier expected to withstand multiple bombs and torpedo strikes. However, design faults and poor damage control allowed it to be sunk with one torpedo from the USS Albacore on 19 June 1944.
