Ibuki — Japan Tech Tree Tier IX Cruiser.

An improved heavy cruiser based on the Mogami-class ships. Cruiser Ibuki was laid down in April 1942 and launched in May 1943. In August, it was decided to rebuild the cruiser as a light aircraft carrier. Reconstruction began later the same year. However, work on the ship was halted when she was approximately 80% complete.

Pros
