The Unryū-class aircraft carriers (雲龍型航空母艦, Unryū-gata Kōkūbokan) were World War II Japanese aircraft carriers. Sixteen ships of the class were planned under the Maru Kyū Programme (Ship #302 in 1941) and the Kai-Maru 5 Programme (#5001–5015 in 1942). However, only three of the Unryū-class carriers were completed.
