Battleships (FBB/BB/BBV) Bonuses

Battleships receive accuracy bonuses if the guns are fit and penalties if it is overweight.

Table Explainer

• The table shows an estimated accuracy fit bonus based on having one fit gun equipped.
• For married ships, the overweight penalty is generally reduced by 40%:
  • E.g. a married Kongou with a 46cm receives -6 instead of -10,
  • Some exceptions will receive a bonus instead of a penalty on certain guns after marriage.
• 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 35.6cm equipped receives √2 x 7 = 9.89.
• If guns from different classes are used together, add the modifiers together.
  • E.g. a Kongou with 35.6cm and 41cm mixed receives 7 - 5 = 2.
  • Exceptions arise where different guns of the same class give different bonuses on certain ships, notably Gangut, with what happens when combining 30.5cm and 35.6cm is still under investigation.

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

[math]\displaystyle{ W = \sum^{\text{All Classes}} \left ( C_{k} M_{k} \sqrt{N_{k}} \right ) \% }[/math]

With:

• [math]\displaystyle{ W }[/math] the resulting fit bonus or overweight penalty
• [math]\displaystyle{ C_{k} }[/math] the main coefficient of the equipped gun class. Refer to the above table for the coefficients applied to each Battleship for their respective guns.
• [math]\displaystyle{ M_{k} }[/math] 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.
• [math]\displaystyle{ N_{k} }[/math] the number of equipped guns for that gun class.
