Fit Bonus and Overweight Penalty

With the introduction of fit gun mechanics on July 28th 2014, ships now will receive fit bonus/penalties depending if the equipped gun fits for the class or if the gun is too heavy for the ship to use.

As fit bonuses are unaffected by morale or combined fleets, it becomes important that you utilize the fit bonuses as much as possible.

Fit mechanics do not apply to the abyssal fleet.[1]

Battleships

Battleships receives accuracy bonuses if the guns are fit and accuracy penalties if its overweight.[2] 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.

Note: The gun classification is only there as a reference for editors and does not reflect the terminologies used in-game.

Note: Fit gun mechanics are still being investigated to this day, hence the values are not final and may be subject to changes. Values with a question mark either means that its not conclusive yet or the conclusion drawn here is not the same as the one drawn by yumeji.

  • The table shows an estimated accuracy fit bonus based on having one fit gun equipped.
  • 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).
  • 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)
  • 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.
  • Exceptions arises where different guns of the same class gives different bonuses on certain ships, notably Gangut. What would happen if you combine 30.5cm and 35.6cm is still under investigations.

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

Where:

  • is the resulting fit bonus or overweight penalty
  • is the main coefficient of the equipped gun class. Refer to the above table for the coefficients applied to each Battleship for their respective guns.
  • is the marriage coefficient for the particular gun class. Assumes a value of 0.6 if the ship is married, and if the main coefficient is negative.
  • is the number of equipped guns for that gun class.

Cruisers

Cruisers can receive accuracy and/or firepower bonuses from using fit guns in their load-out. Unlike battleships however, cruisers do not suffer from any overweight penalty nor do overweight guns for cruisers exists.

Note: Fit gun mechanics are still being investigated to this day, hence the values are not final and may be subject to changes. Values with a question mark means that it is potentially outdated and might no longer be correct.

  • The table shows an estimated accuracy and/or firepower fit bonus based on having one fit gun equipped.
  • Bonuses from guns of different classes are simply added together.
  • If more than one gun of the same class is used, multiply the modifier by the square root of number of guns (Ooyodo with two 15.5cm guns equipped for example, that's √2 x 7 = 9.89). Note that this also applies to firepower bonuses!
  • The night fit bonus from the 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.
  • There is a possibility that certain fit categories only work during the day. The possibility is plausible, but there's no concrete data proving. The alternative theory is that the night bonus from the 20.3cm series overrides any other categories.
  • The fit mechanics for CL(T)/CT is currently broken, preventing them from gaining any fit bonuses. This bug has not been fixed yet as of February 15th 2018.

Single Mount High-Angle Bonus

As of June 23, Yura and Mutsuki/Kamikaze-class destroyers gain fit bonuses from having single mount High-angle Gun equipped.

Unknown factors:

  • Only Yura K2Yura Kai Ni and Satsuki K2Satsuki Kai Ni were tested. It's unknown whether the other ships in the same class would receive the same bonus or whether it only works for specific remodels.
  • It has not been tested with multiple guns, it's unknown whether it works the same as the other fit mechanics.
  • It is unknown whether the 12.7cm Single Gun Mount gives a fit bonus or not.
