Mogami — Japanese Tier VIII cruiser.

Mogami was built as a light cruiser whose characteristics would largely exceed those of her contemporary counterparts. She had good armor along with a powerful artillery and torpedo armament. During the course of her service she was transformed into a heavy cruiser, as intended by the original design.

For a graphic summary of ships Tiers VIII thru XI see LittleWhiteMouse's "Actual AA DPS".

Mogami-class has a rather unique style in game play among all the cruisers at the current iteration as she can have two modes of offense: her 155's which can burn or pummel ships or the harder yet slower loading 203's which technically turns her into a heavy cruiser. The 155's guns comes at her stock hull as she was actually armed with them before being reformatted and reclassified as a heavy cruiser in between 1938 to 1939. The 203's make her into a standard heavy cruiser that has good damage at the cost of slower loading time and reasonable turret turn although this gives her the much needed punch to deal with other heavy cruisers and potentially battleships. Whatever guns you mount, you will find her to be one dynamic ship at her tier.

Pros:

Modular gun system which gives you freedom of play style.
Reasonable range.
155's are extremely numerous.
155's have a high initial shell velocity at 925 m/s, making them very good at hunting destroyers.
155's have superb HE penetration if player has Inertia Fuse High Explosive skill.
155's have high damage per minute when compared to her 203's or other same-tier ship
203's have good firing arc and turret rotation speed.
Friendly ergonomics and handling.
Impressive rudder shift.
Good torpedo range.
Very good concealment.

Cons:

Fragile. Armor is made of paper.
the AA suite is insufficient to defend yourself alone.
155's turrets have a good chance to be incapacitated, if not outright destroyed.
155's turrets turn slowly at 36 seconds for 180 degrees.
Without Inertia Fuse High Explosive skill, 155's will have problems against battleships or other highly armored ships as 155's will not penetrate 32 mm of armor, forcing the player to rely on HE to deal damage and set the superstructure and deck on fire.
203's have lesser damage per minute when compared to her 155's.
203's reload time is slower than Myoko's by a second.
Inconvenient torpedo tube placement, very limited arc.

Research

It is suggested to research Hull B first to get more HP, then finally acquire the upgraded Fire Control System to kite away ships better.

As for the gun options, the 155's are best to use (with Inertia Fuse High Explosive skill) if players want to keep the ship in the port. The 203's are generally optional as the 155's with Inertia Fuse High Explosive can deal better damage, meaning it can be skipped entirely or researched depends on player's choice. The 203's however, unlike the 155's, does not need to use Inertia Fuse High Explosive skill as it has enough HE penetration to damage 32 mm of armor.

Optimal Configuration

Mogami is a ship with good handling and can be used to kite battleships and other cruiser from afar and tank damage by dodging enemy shells and/or torpedoes.

Upgrades

The recommended upgrades for Mogami are as follows:

Slot 1: Main Armaments Modification 1 keeps the guns and torpedo tubes active and firing.
Slot 2: Engine Room Protection to keep the rudder in action.
Slot 3: Main Battery Modification 2 makes her guns more comfortable and saves a skill point that would otherwise be spent on Grease the Gears to improve her gun handling with the 155 mm guns. Aiming Systems Modification 1 gives her guns more accuracy and is an alternative option, particularly for the 203 mm guns, which have a higher base traverse speed than the 155 mm guns.
Slot 4: Steering Gears Modification 1 allows for a faster rudder shift to dodge incoming fire. Propulsion Modification 1 can also be used to aid dodging incoming fire and torpedoes via speed juking, depending on your preferred play style.
Slot 5: See below.

Concealment Build: Currently the most popular build of the ship. Captains wishing to focus their Mogami to maximize her concealment will opt for Concealment System Modification 1 

in Upgrade Slot 5. This will lower her surface detection up to 9.4 km, enabling her to do stealth torpedo attack since her torpedo range is 10 km. This can be used to ambush ships with more than her concealment. Although, stealth torpedoing will make Mogami prone to radar scan by 9.5 km or more radar-equipped ships like Indianapolis, Baltimore, Neptune, Missouri, Des Moines, Minotaur, and the Russian cruisers. Furthermore, Mogami has bad torpedo firing arc, with the arc only good enough to fire an incoming ship from behind.

Maneuverability Build: A rather advanced build of the ship. Captains wishing to focus maneuverability will opt for Steering Gears Modification 2

in Upgrade Slot 5. This, when combined with Steering Gears Modification 1, will lower her rudder shift time up to 3.4 s, while maintaining 10.3 km surface detection range. 3.4 s rudder shift time can turn Mogami into one of the best kiting ship. Excellent rudder shift time, good turning radius, and great deceleration making her very hard to hit with the right hand. This, however, has to be paid by her concealment as Steering Gears Modification 3 have the same slot as Concealment System Modification 3. Absolute knowledge of situational awareness is also needed to know when and where to shoot and kite.

Commander Skills

The key skills for Mogami represent a continuing evolution of the Japanese cruiser tech tree ships towards improved stealth, with Mogami being the first one since Kuma to drop below 10 km detection when fully built for stealth. As such, the core skills remain the same with Gun Feeder at Level 1, Priority Target at Level 2, Adrenaline Rush at Level 3, and Concealment Expert at Level 4. One caveat to these core skills is that Inertial Fuse for HE Shells is highly suggested for captains who plan to use her 155 mm guns instead of the 203 mm guns so that she can pen 32 mm armor. Additionally, captains planning to use the 155 mm guns who have opted for improving her accuracy with Aiming Systems Modification 1 in Upgrade Slot 3 are encouraged to pick up Grease the Gears as your Level 1 skill instead of Gun Feeder in order to make her sluggish turret traverse more comfortable. As with previous ships, and most cruisers, AA skills continue to be a good choice, especially Expert AA Marksman. Where differences from previous ships start to manifest is in the non-core skills. With a relatively small base detection radius, Top Grade Gunner becomes considerably less useful than it may have been for previous ships in the line. On the other hand, her stealth is so good that taking Heavy HE and SAP Shells in addition to Concealment Expert still leaves her with better concealment than Myoko had at the previous tier; however, this leaves her vulnerable to ships she would otherwise out-spot.
