flag shipicon Chikuma II: Tier IX Japanese Premium Hybrid Cruiser 1939

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.

Key Features:

  • Her main battery is represented by eight 203mm guns in four twin turrets with slow traverse speed and limited firing angles, resulting in rather low damage per minute.
  • In comparison to her sister ship, Chikuma II’s torpedo bombers will reload more quickly, have more damage potential, and can be stored as up to two charges.
  • Additionally, her ship-mounted torpedoes will have long range, high damage, and improved launch angles due to the torpedoes’ ability to turn after hitting the water.
  • Excellent concealment and access to the Smoke Generator consumable will be valuable tools, but her small HP pool and weak AA means captains should take care when detected.
  • Chikuma II also has access to Hydroacoustic Search and Defensive AA Fire in the same slot.


Chikuma II heavily relies on her squadrons and will be most effectively played by using her stealth to take advantageous fights. Enemy targets may be softened up by using her torpedo bombers and high-damage torpedoes, then followed up with main battery salvos from the cover of smoke. In direct confrontations, Chikuma II will fare poorly against her peers, so captains will want to avoid engagements in open water against enemy cruisers and battleships.

  1. Chikuma ii is so unbelievably bad. The Tone is already bad for tier 8, Chikuma ii is Tier 9 whilst being almost identical. The only distinct difference is the planes, and it is not in Chikuma's favour.
