WoWS Fitting Tool

Tier 4 Japan Cruiser
Iwaki Alpha
An advanced design of the Tenryū-class cruiser. The ship's displacement exceeded that of her predecessor, which allowed for a reinforced artillery armament and more powerful propulsion. At the project design stage, the cruiser was faster than all existing cruisers and many destroyers.
