21,500 doubloons

Chikuma II — Japan Premium Tier IX Cruiser.

A Tone-class heavy cruiser, this warship represents an advancement from the Mogami class. Notably, all four main battery turrets are situated on the ship's bow, a distinctive feature of this series. Designed for extended-range reconnaissance, escort duties, and supporting aircraft carrier formations, this warship boasts an augmented cruising range and carries an onboard air group. Throughout World War II, the cruiser took part in most major operations conducted by the Japanese Navy. In October 1944, Chikuma was sunk during the Battle of Leyte Gulf.

This ship has access to a squadron of torpedo bombers.

Pros
