Ship:Ishizuchi

IV

2,500 doubloons

Ishizuchi — Japan Premium Tier IV Battleship.

The original Vickers project commissioned by Japan had five twin-gun turrets with 305 mm guns. The client, however, was not satisfied with the test results of the British 305 mm guns. Further development led to the creation of the Kongō-class battleships.

Pros
