Hidden fit bonus mechanics are still being investigated to this day, hence the values are not final and may be subject to changes. Cases with a question mark (?) are lacking enough data or are unmapped yet, and so may be outdated and/or erroneous. The developers have also adjusted hidden fits multiple times. |
The "hidden fit bonus" mechanic refers to some ships receiving bonuses or penalties when equipping certain equipment, depending on if the equipment "fits" the class or not.
- This almost exclusively refers to main guns, where each class of ship is engineered to carry up to certain gun calibers, and so, equipping gun turrets of the right caliber or lower will imply an accuracy bonus, whereas using larger calibers will result in some overweight penalties.
- So far, all fits involve Accuracy , and some also affect Firepower (excluding #Arctic Map Bonuses unic case).
- Accuracy bonuses work like regular visible stat, see here for more information.
- Firepower bonuses are "pre-cap",
- Not to be confused with visible Equipment Bonuses.
As hidden bonuses are unaffected by morale or fleet types (e.g. combined fleets), it can be interesting to utilize those fit bonuses as much as possible.
How much bonus/penalty a ship receives, depends on:
- The ship class, larger classes being able to carry larger equipment,
- If the ship is married or not, married girls having better fits,
- The gun size (caliber and quantity per turret), the larger ones being the most constraining.
- Some other less frequent factors:
- The ship's remodel,
- The ship's speed,
- Whether it is a day or night battle.
Battleships (FBB/BB/BBV) Bonuses
Battleships receive accuracy bonuses if the guns are fit and penalties if it is overweight [1].
Table Explainer
When equiping '"Large Caliber Main Guns" on a FBB/BB/BBV, the resulting accuracy bonus/penalty is:
Fit Formula |
---|
[math]\displaystyle{ \text{ACC}_\text{bonus} = \sum^{\text{All Groups}} C_{Group} \times \sqrt{N_{Group}} \times M }[/math]
For BB only: if the base maximum HP (unmodified & before marriage) is superior to 92, set fit bonuses are set to 0. Do note that speed modding ships (to Fast+) has been observed to worsen the penalties on certain ships.

Cruiser Bonuses
- Notes
- Future Medium Guns may fall in one of those categories based on similarities like caliber and number of guns.
- Groups A, B, C, D, and E are "Light Cruiser Guns", and Groups F and G are "Heavy Cruiser Gun".

- There is not enough data to pin down the exact fit accuracy formula.
- Other gun combinations fits cannot be extrapolated yet.
- There are known tests where the fit bonuses do not scale linearly with the number of guns.
- ↑ Changing gun order does not affect the final bonus
- ↑ Light Cruiser Tsu-Class
- ↑ Light Cruiser Ho-Class, Light Cruiser He-Class, Light Cruiser To-Class, Torpedo Cruiser Chi-Class

- The table shows an estimated accuracy and/or firepower fit bonus based on having one fit gun equipped.
- The variable N refers to the number of guns of that category equipped
- E.g. 2 guns of 2N = 4 Acc
- Bonuses from guns of different classes are simply added together.
- The night fit bonus from the IJN 20.3cm series used to be capped at +15%. However, it is unknown whether this cap has been removed or not from the recent updates.
- As of 13th December 2018 the hidden firepower bonus of 14cm Twin Gun Mount Kai does not work/does not exist[citation needed].

- Notes
- Only Yura Kai Ni and Satsuki Kai Ni were tested. It is unknown whether the other ships listed also receive those bonuses, or whether it only works for specific remodels.
- The variable N refers to the number of guns of that category equipped (ex: 2 guns of 2N = 4).

Destroyer (DD) Bonuses
Certain destroyers receive some Accuracy bonuses when equipped with certain guns or sonars. The resulting accuracy bonus is:

- ↑ 2x base 5" Gun on Fletcher-class gives ~10 accuracy. This is potentially a bug.
- ↑ Samuel B.Roberts does not seem to receive any bonus from base 5" Gun. This is possibly a bug (maybe related to the bug on Fletcher-class).
- ↑ There are not enough samples on more than one ASDICs
sonar so it is not clear how does the accuracy bonus scales. This bonus can stack with the accuracy bonus from QF 4.7inch Gun Mk.XII Kai.
