IJN Amagi

The Japanese aircraft carrier IJN Amagi in 1944.

The Unryū-class aircraft carriers (雲龍型航空母艦 Unryū-gata Kōkūbokan?) were World War II Japanese aircraft carriers. Sixteen carriers were planned under the Maru Kyū Programme (Ship #302 in 1941) and the Kai-Maru 5 Programme (#5001–5015 in 1942). However, only ten carriers were completed. Unryū, Katsuragi and Kasagi participated in the Battle of the South China Sea, where Unryū was sunk by Allied bombing.

Unit RunEdit


Project number was G16. General production model of the Unryū-class. Seven were built The IJN unofficial designation for Unryū-subclass was Modified Soryū-class (改飛龍型 Kai Hiryū-gata). Ship Numbers 5002–5006 were Modified Unryū-class (改雲龍型 Kai Unryū-gata)


Simplified and sped-up construction model of the Unryū class. They fitted shift-arrangement machinery (four sets of parallel two boilers and one turbine). Therefore, as for their chimneys/funnels/smokepipes/uptakes, those were intended to be spaced out. The IJN unofficial designation for this class was Modified Ship Number 302-class (改第302号艦型 Kai Dai 302-Gōkan-gata).
