The IJN Mogami is one of the most well protected cruisers in the game, with 140 mm of RHA covering the entire front and rear ammunition stowages, 100 mm of RHA protecting the engine compartment, 105 mm of RHA bulkheads, though this will NOT stop other heavy cruisers from ammoracking you if you do not angle. The ship has 910 crew which is just mediocre for a heavy cruiser. The major downside of this ship is its extremely thin (25.4 mm) turret armour so users will have a hard time dealing with HE spam from US destroyers and light cruisers.

If there is no additional armament, remove this section.

Usage in battles

Describe the technique of using this ship, the characteristics of her use in a team and tips on strategy. Abstain from writing an entire guide – don't try to provide a single point of view, but give the reader food for thought. Talk about the most dangerous opponents for this vehicle and provide recommendations on fighting them. If necessary, note the specifics of playing with this vehicle in various modes (AB, RB, SB).

Pros and cons

Pros:

  • Good armour when angled
  • Decent mobility
  • 24 devastating Long lance torpedoes at its disposal
  • The ability to seemingly eat infinite amounts of ship torpedoes to the bow and or stern

Cons:

  • Extremely weak turret armour
  • Very slow turrets traverse time (4.0 degrees per second)
  • Easy to ammorack when unangled

History

Development of the Mogami-class cruiser dates back to the early 1930s, when the IJN launched its development as part of a naval rearmament program. Wishing to substantially strengthen their navy's cruisers, the IJN high command ordered for a new design to be drawn up which would practically reach the very limits of the London Naval Treaty in effect at the time.

The new warship was initially set at a displacement of 8,500 tons and was to be armed with fifteen 155mm guns, spread across five triple turrets. However, even at the design stage it was already clear that the real displacement would significantly exceed this limit and would be around 11,000 tons so it was decided to conceal the true data. In December of 1934, Japan denounced the Washington Agreements, and refused to sign the Second London Treaty in January of 1936. As a result, in the period between 1939 and 1940 all cruisers of the Mogami type underwent reconstruction, in which the main weapons were replaced by ten 203-mm guns in five turrets, the ships were then formally reclassified as heavy cruisers.

Nonetheless, Mogami-class cruisers raised concerns with other naval powers, some simply dismissed their design specifications as being false, while others, such as the U.S., began building counterparts of their own. Four Mogami-class heavy cruisers took part in several major operations during WW2, including the Battle of Midway, Leyte Gulf and many others. All ships of the class were lost in combat between June 1942 - November 1944.
