Cruiser Bonuses

Table Explainer

When equiping '"Medium Caliber Main Guns/Secondary Guns" on a CA/CAV/CL/CLT/CT/Aux, 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] With [math]\displaystyle{ \text{All Groups} }[/math] the gun groups and sub-groups defined in the following tables. [math]\displaystyle{ C_{Group} }[/math] the accuracy modifier of the group, given in the following table. When a ship has additional bonuses to a group compared to her type, this bonus is summed as a separate "Group". [math]\displaystyle{ N_{Group} }[/math] the number of guns of a same group. [math]\displaystyle{ M }[/math] the Marriage bonus of 0.6 when applicable, 1 else. This bonus is applied only for Groups marked by footnote [1], When applied, this bonus is applied in all situations, with penalties being reduced by 0.6, as well as bonuses being reduced by 0.6. ???Do note that speed modding ships (to Fast+) has been observed to worsen the penalties on certain ships. Examples

• 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.

• 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.
  • It is possible that certain fit categories only work during the day, but there is no concrete data proving it yet.
  • It is alternatively possible that the night bonus from the IJN 20.3cm series overrides any other categories.
  • Such fit mechanics do not apply to abyssals.

• As of 13th December 2018 the hidden firepower bonus of 14cm Twin Gun Mount Kai does not work/does not exist^{[citation needed]}.
