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.

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.

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.

Battleships receive accuracy bonuses if the guns are fit and accuracy penalties if it is overweight<ref>https://twitter.com/KanColle_STAFF/status/493648336142876674</ref>. How much bonus/penalty a ship receives, depends on the battleship class, the caliber and type of the gun, and whether the battle takes place during day or night.

* For married ships, the overweight penalty is reduced by 40% (A married Kongou with a 46cm receives a penalty of -6 instead of -10, for example).

* For married ships, the overweight penalty is generally reduced by 40%:

* If more than one gun of the same class is used, multiply the modifier by the square root of number of guns. (A Kongou-class with two A class guns equipped for example, that's √2 x 7 = 9.89)

** E.g. a married Kongou with a 46 cm receives -6 instead of -10,

* If guns from different classes are used together, add the modifiers together. (A Kongou with a 35.6cm and 41cm mixed for example, that's 7 - 5 = 2.

** Some exceptions will receive a bonus instead of a penalty on certain guns after marriage.

* Exceptions arise where different guns of the same class give different bonuses on certain ships, notably Gangut. What would happen if you combine 30.5cm and 35.6cm is still under investigation.

* If more than one gun of the same class is used, multiply the modifier by the square root of the number of guns:

** E.g. a Kongou with two IJN 35.6 cm equipped receives √2 x 7 = 9.89.

* If guns from different classes are used together, add the modifiers together.

** E.g. a Kongou with 35.6 cm and 41 cm mixed receives 7 - 5 = 2.

More generally, the accuracy offset can be defined with the formula:

Since gun overweight penalty and fit bonuses are not yet all measured for some guns and ships, here is a list of the guns natively used/planed to be used in real life by each ship class.
