Ōta — Japan · Tier IX · Cruiser

A hypothetical "improved Agano"-class light cruiser that could have been built at the height of the Pacific War. To strengthen the ship's anti-aircraft capabilities, she could have been completed using a reworked design. In particular, the 152 mm guns that were traditional for a light cruiser could have been replaced with 100 mm dual-purpose mounts that had proven themselves as the main armament of Akizuki-class destroyers.
