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 Swordfish-series
  
  , 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
Airstrike - The fits given by the Skilled Deck Personnel + Aviation Maintenance Hands works as intended.
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]

Accuracy:
- Works for shelling phases^[2].
- Does not work for Support Expedition^[3].

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 for the following cases:
  - 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.
  - Damage of Carrier Night Attacks [1].
  - Damage of ASW Support [2].
  - The Armor Penetration of depth charge [3].

Anti-Air: Works for Air Defense Phase.
- However bonus granted to aircraft does not contribute to Air Power^[4].

Airstrike - The fits given by aircraft affect only one plane and do not works in some situation.

Night Carrier Cut-in Attack: Only of the fits of Skilled Deck Personnel + Aviation Maintenance Hands work^[5]^[6]^[7].
- Additionally, any base granted by equipment other than night plane provide not increase damage 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:

[math]\displaystyle{ \text{Final Value} = \text{Base Stat} + \text{Equipment Stat} + \text{Fit Bonus} }[/math]

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.

Airstrike

There are two completely independent systems for torpedo and dive bombing fit bonuses affecting airstrike damage:

The fits given by the SDP+,
The fits given by aircraft equipment.

As they are independent the effects of both systems stack.

Skilled Deck Personnel + Aviation Maintenance Hands

fits affect equally all equipped on the ship,
fits affect equally all and Bomber equipped on the ship,

Planes

If one or multiple planes have fits, only one is chosen based on a priority order. The fits given by this plane are then applied to the equipped attack plane with the highest /.

Note that if the fit is +0 for the current ship it will still be chosen and then give 0.

The priority list

Priority	Planes
1	Recon Type 0 Small Reconnaissance Seaplane Recon Type 0 Small Reconnaissance Seaplane (Skilled)
2	Recon Type 0 Reconnaissance Seaplane Model 11B Recon Type 0 Reconnaissance Seaplane Model 11B (Skilled)
3	Recon Shiun (Skilled)
4	Recon Shiun
5	Bomber Swordfish Mk.III Kai (Seaplane Model)
6	Bomber Swordfish Mk.III Kai (Seaplane Model/Skilled)
7	Tenzan Model 12A
8	Tenzan Model 12A Kai (w/ Type 6 Airborne Radar Kai)
9	Tenzan Model 12A Kai (Skilled w/ Type 6 Airborne Radar Kai)
10	Barracuda Mk.III
11	Barracuda Mk.II

Notes

As they have the same priority order, if both Type 0 Small Reconnaissance Seaplane (Skilled) and Type 0 Small Reconnaissance Seaplane are equipped their bonuses stack.
As it is a one-time bonus the fits of Type 0 Reconnaissance Seaplane Model 11B (Skilled) and Type 0 Reconnaissance Seaplane Model 11B cannot stack.
The priority of the Tenzan Model 12A Kai (Skilled w/ Type 6 Airborne Radar Kai) is not confirmed due to a lack of data.

Example

For a Shoukaku Kai Ni A equipped with:
- Tenzan Model 12A with +1 fits
- Tenzan Model 12A Kai (w/ Type 6 Airborne Radar Kai) with +2 fits
- The resulting fits will be +1 because the Tenzan Model 12A has a higher priority.
For a Gotland Andra equipped with:
- Recon Shiun (Skilled) with +0 fits
- Bomber Swordfish Mk.III Kai (Seaplane Model/Skilled) with +3 fits
- The resulting fits will be +0 because the Recon Shiun (Skilled) has a higher priority.
For a I-14 Kai equipped with:
- Recon Type 0 Small Reconnaissance Seaplane (Skilled) with +3 fits
- Recon Type 0 Small Reconnaissance Seaplane with +1 fits
- Bomber Swordfish Mk.III Kai (Seaplane Model/Skilled) with +0 fits
- The resulting fits will be +4 because the Recon Type 0 Small Reconnaissance Seaplane and the Recon Type 0 Small Reconnaissance Seaplane (Skilled) have the same priority.

Source: [4]

Fixed

LoS: SG Radar (Initial Model) did not contribute for any calculation^[10].
- It was fixed with the introduction of the SG Radar (Late Model).
ASW: 28/09/2021 Global ASW bonus fixes^[11].
AA: 04/08/2022 update
Speed: The Houshou Kai Ni/Sen bonus didn't work properly on implementation.

Display Bugs

Some bonus preview values, as displayed with ↑+ on the equipment card, are inconsistent with the ship's stat totals after equipping the equipment. In such cases, the ship's stat totals reflect the actual correct values used in battle calculations^[12], whereas the preview values are visual bugs.
