# Equipment Bonuses

One additional Firepower gained from equipping a 12.7cm Type C Gun Mount

Equipment Bonuses refer to specific ship-equipment combinations that trigger a modification in some specific Stats with values referred to as "Fit Bonuses".

• These are displayed in the game by a ↑+ or ↓- symbol in front of each applicable stat.
• Some of those bonuses may:
• Synergize, being greater when being combined with other equipment,
• Be affected by Improvements, the number of stars improving the bonuses.
• These bonuses must not be confused with the "Hidden Fit Bonuses", to Accuracy and Firepower.
• To differentiate with "hidden Fit Bonuses", they are also referred to as "Visible Fit Bonuses".

# Fit Bonus Specifics

Although displayed in the game, some Fit Bonuses have an erroneous effect or outright do not work.

Visible fits will always work for raw stat requirements such as for Expeditions, but some may not work as intended in formulas used in sorties.

As of 28 April 2022, the following Fit Bonuses present issues.

## Functional

These Fit Bonuses work in every scenario:

• Evasion.
• Armor.
• Speed.
• Range.
• "Longest Range" is only displayed as "Very Long Range", but still works as intended.

### Formulas

• Day Surface Shelling - All Firepower fits work as intended.
• Night Surface Shelling - All fits work as intended.
• Especially for Ark Royal and , the torpedo stat does not work.
• Carrier Shelling - All fit sources work as intended. The Torpedo fit will now be included for shelling power calculation (NEW) 04/08/2021
• Airstrike - All fits work but not as intended. The Torpedo fit will be added to airstrike power to either Dive Bombing stat or Torpedo depending on the type of the plane. (NEW) 04/08/2021
• Torpedo Attacks - All Torpedo fits work as intended.
• This includes fits provided by sources that are not torpedoes, such as seaplanes and lookouts.

## Partially functional

These Fit Bonuses have at least one situation in which they don't work as intended:

• LoS: Bonuses count as ship base LoS and not equipment, for routing purposes. No effect for artillery spotting.[1]

### Formulas

• Anti-Submarine Shelling: All ASW fits work as intended, both towards damage and OASW ship stat thresholds.
• This includes fits provided by sources that don't count towards ASW damage, such as Reconnaissance Seaplanes & Carrier-Based Fighter Aircraft.
• Does not count as equipment ASW for equipment stat OASW thresholds. E.g. A plane with 6 base ASW & a 1 ASW fit does not count as a 7asw plane.
• Anti-Air: Works for Air Defence Phase.
• However bonus granted to aircraft does not contribute to Air Power[4].
• Night Carrier Cut-in Attack: Only of the fit of work[5][6][7].
• Additionally, any base granted by equipment other than night plane provide no damage increase for this formula[8][9] .

# Explanation

Fit Bonuses are not considered a part of an equipment's stat, and are instead added to the ship's actual stat directly. This is what leads to inconsistencies in the formulas.

The displayed value in a given stat is given by:

$\displaystyle{ \text{Final Value} = \text{Base Stat} + \text{Equipment Stat} + \text{Fit Bonus} }$

Where:

• Final Value is the displayed Value in the ship card.
• Base Stat is the stat without any equipment.
• Equipment Stat is the equipments displayed stat.
• Fit Bonus is the added value to the stat by fits.

Some formulas, such as Surface Shelling, Opening/Closing Torpedo Salvos, and Carrier Shelling use the Final Value. In those cases, the fit bonuses work as intended.

However, other formulas break down the stats for various reasons (mainly for applying different weighting to equipment, as in ASW and Anti-Air formulas, or using other parameters like the Accuracy formula), and instead use Base Stat and the sum of Equipment Stats instead. In those cases, Fit Bonus is not used anywhere in the formula, and therefore does not work.
