+
The '''"hidden fit bonus"''' mechanic refers to some ships receiving bonuses or penalties when equipping certain equipment, depending on if the equipment "fits" the class or not.
 +
*This almost exclusively refers to main guns, where each class of ship is engineered to carry up to certain gun calibers, and so, equipping gun turrets of the right caliber or lower will imply an accuracy bonus, whereas using larger calibers will result in some overweight penalties.
 +
*So far, all fits involve Accuracy {{Hit}}, and some also affect Firepower {{Firepower}} (excluding [[#Arctic Map Bonuses]] unic case).
 +
**Accuracy {{Hit}} bonuses work like regular visible {{Hit}} stat, see ''[[Accuracy|here]]'' for more information.
 +
**Firepower {{Firepower}} bonuses are '''"pre-cap"''',
 +
*Not to be confused with visible [[Equipment Bonuses]].
 +
As hidden bonuses are unaffected by morale or fleet types (e.g. combined fleets), it can be interesting to utilize those fit bonuses as much as possible.
  
==Fit Bonus and Overweight Penalty==
+
How much bonus/penalty a ship receives, depends on:
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.
+
*The '''ship class''', larger classes being able to carry larger equipment,
 +
*If the ship is '''[[Marriage|married]]''' or not, married girls having better fits,
 +
*The '''gun size''' (caliber and quantity per turret), the larger ones being the most constraining.
 +
*Some other less frequent factors:
 +
**The ship's '''remodel''',
 +
**The ship's '''speed''',
 +
**Whether it is a '''day or night''' battle.
  
As fit bonuses are unaffected by morale or combined fleets, it becomes important that you utilize the fit bonuses as much as possible.

 +
Battleships receive accuracy {{Hit}} '''bonuses''' if the guns are fit and '''penalties''' if it is overweight [https://twitter.com/KanColle_STAFF/status/493648336142876674].  
  
Fit mechanics does not apply to the abyssal fleet.<ref>https://twitter.com/KanColle_STAFF/status/380246238991364096</ref>
+
===Table Explainer===
 +
When equiping {{RedGunHeavy}} '''"[[Large Caliber Main Gun]]s"''' on a FBB/BB/BBV, the resulting accuracy bonus/penalty is:
 +
{{Formula
 +
|Title=Fit Formula
 +
|Math=\text{ACC}_\text{bonus} = \sum^{\text{All Groups} } C_{Group} \times \sqrt{N_{Group} } \times M
 +
|Var=<math>\text{All Groups}</math> the gun groups and sub-groups defined in the following tables.
 +
*<math>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>N_{Group}</math> the number of guns of a same group.
 +
*<math>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.
 +
**For {{Class|Iowa}} with the '''USN 16" Mk7''' guns, '''M''' may be better, the observed bonu being <math>\text{ACC}_\text{bonus} = 6 \times \sqrt{N_{16inch Mk.7}} + 12 \times \sqrt{N_{16inch Mk.7 GFCS}} </math>.
 +
|Notes=For [[BB]] only: if the base maximum HP {{HP}} (unmodified & before marriage) is superior to 92, set fit bonuses are set to '''0'''.
 +
*Do note that [[Speed|speed modding]] ships (to Fast+) has been observed to worsen the penalties on certain ships.

*<math>\text{ACC}_\text{bonus} = C_{35.6 cm FBB} \times \sqrt{N_{35.6 cm}} + C_{35.6 cm Kongou-class} \times \sqrt{N_{35.6 cm}} = ( 4 + 3 ) \times \sqrt{2} = +9.90</math>

*This bonus stays the same when married, as no '''M''' multiplier is applied in this case.

[[Musashi Kai Ni]] equiped with 1 {{Equipment/Link|51cm Twin Gun Mount|text=IJN 51cm Twin}} and 1 {{Equipment/Link|Prototype 51cm Triple Gun Mount|text=IJN 51cm Triple Proto}}
Battleships receives accuracy bonuses if the guns are fit and accuracy penalties if its overweight.<ref>https://twitter.com/KanColle_STAFF/status/493648336142876674</ref>
+
*<math>\text{ACC}_\text{bonus} = C_{51 cm Musashi Kai Ni} \times \sqrt{N_{51 cm}} = 0 \times \sqrt{2} = +0.00</math>
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.
+
*Musashi Kai Ni has 99 bases {{HP}}, and so has bonuses set to ZERO for those guns.

* 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.

+
{{Clear}}
<math>W = \sum^{\text{All Classes}} \left ( C_{k} M_{k} \sqrt{N_{k}} \right ) \%</math>

'''''Sources: [https://twitter.com/Divinity__123/status/1529359629574189057] [https://docs.google.com/spreadsheets/d/1Xm5VRj1FwgwlRISAyuwJgOJiBgOGOcGQJNcJ-pZHGFo/edit#gid=0]'''''
 
 
Where:
 
*<math>W</math> is the resulting fit bonus or overweight penalty
 
*<math>C_{k}</math> 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.
 
*<math>M_{k}</math> 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.
 
*<math>N_{k}</math> is the number of equipped guns for that gun class.
 
 
 
==Heavy Cruisers==
 
Heavy/Aviation cruisers only require one fit gun to get their fit bonus, there are no overweight mechanics regarding cruisers. Keep in mind that the fit bonus only applies during a night battle and equipping more than one of the same fit gun will not give you any duplicate bonuses. The fit bonuses also apply to torpedo attacks, as there are no distinction between shelling or torpedo based night attacks.<br />
 
The following guns will give you a fit bonus:
 
* {{EquipmentLink|20.3cm Twin Gun Mount}} +10%
 
* {{EquipmentLink|20.3cm (No.3) Twin Gun Mount}} +15%
 
 
 
'''Note:''' It is currently unknown what would happen if you combine different fit guns.
 
 
 
The following guns are confirmed not to give any fit bonuses:
 
* {{EquipmentLink|20.3cm (No.2) Twin Gun Mount}}
 
* {{EquipmentLink|SKC34 20.3cm Twin Gun Mount}}
 
 
 
==Light Cruisers==
 
Light Cruisers, Torpedo Cruisers and Training Cruisers all enjoy an accuracy and firepower bonus when equipped with fit guns. Like Heavy Cruisers, Light Cruisers do not have overweight mechanics.<ref>https://twitter.com/KanColle_STAFF/status/600208207454146561</ref>
 
===Firepower===
 
Light Cruisers, Training Cruisers, and Torpedo Cruisers enjoy firepower increase when using any of the following gun:<ref name=CLFG>[http://ja.kancolle.wikia.com/wiki/%E5%B7%A1%E6%B4%8B%E8%89%A6%E4%B8%BB%E7%A0%B2%E3%80%90%E3%83%95%E3%82%A3%E3%83%83%E3%83%88%E8%A3%9C%E6%AD%A3%E3%80%91 巡洋艦主砲【フィット補正】]</ref>

* Increase in Firepower = √(No. of Fit Single Gun Mount) + 2 × √(No. of Fit Twin Gun Mount)
 
 
 
===Accuracy===
 
So far, only limited amount of tests have been conducted to study light cruiser fit gun's effect on accuracy so all information in this section are in-comprehensive and they might be superseded by other, more up-to-date investigations when those information are available.
 
 
 
The accuracy fit bonus only applies if 2 or more fit guns are equipped at the same time. Equipping more than 2 fit guns does not increase the fit bonus.<ref>https://twitter.com/buntan_oic/status/759254902287851524</ref>

The "hidden fit bonus" mechanic refers to some ships receiving bonuses or penalties when equipping certain equipment, depending on if the equipment "fits" the class or not.

  • This almost exclusively refers to main guns, where each class of ship is engineered to carry up to certain gun calibers, and so, equipping gun turrets of the right caliber or lower will imply an accuracy bonus, whereas using larger calibers will result in some overweight penalties.
  • So far, all fits involve Accuracy Accuracy, and some also affect Firepower Firepower (excluding #Arctic Map Bonuses unic case).
    • Accuracy Accuracy bonuses work like regular visible Accuracy stat, see here for more information.
    • Firepower Firepower bonuses are "pre-cap",
  • Not to be confused with visible Equipment Bonuses.

As hidden bonuses are unaffected by morale or fleet types (e.g. combined fleets), it can be interesting to utilize those fit bonuses as much as possible.

How much bonus/penalty a ship receives, depends on:

  • The ship class, larger classes being able to carry larger equipment,
  • If the ship is married or not, married girls having better fits,
  • The gun size (caliber and quantity per turret), the larger ones being the most constraining.
  • Some other less frequent factors:
    • The ship's remodel,
    • The ship's speed,
    • Whether it is a day or night battle.

Battleships (FBB/BB/BBV) Bonuses

Battleships receive accuracy Accuracy bonuses if the guns are fit and penalties if it is overweight [4].

Table Explainer

When equiping Large Caliber Main Gun "Large Caliber Main Guns" on a FBB/BB/BBV, 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.
    • For Iowa-class with the USN 16" Mk7 guns, M may be better, the observed bonu being [math]\displaystyle{ \text{ACC}_\text{bonus} = 6 \times \sqrt{N_{16inch Mk.7}} + 12 \times \sqrt{N_{16inch Mk.7 GFCS}} }[/math].
Notes
  • For BB only: if the base maximum HP Health (unmodified & before marriage) is superior to 92, set fit bonuses are set to 0.
  • Do note that speed modding ships (to Fast+) has been observed to worsen the penalties on certain ships.
Examples

Kongou Kai Ni equipped with 2 IJN 35.6cm Twin K235.6cm Twin Gun Mount Kai Ni:

  • [math]\displaystyle{ \text{ACC}_\text{bonus} = C_{35.6 cm FBB} \times \sqrt{N_{35.6 cm}} + C_{35.6 cm Kongou-class} \times \sqrt{N_{35.6 cm}} = ( 4 + 3 ) \times \sqrt{2} = +9.90 }[/math]
  • This bonus stays the same when married, as no M multiplier is applied in this case.


Nagato Kai Ni equiped with 1 IJN 41cm Twin41cm Twin Gun Mount and 1 IJN 51cm Twin ProtoPrototype 51cm Twin Gun Mount:

  • [math]\displaystyle{ \text{ACC}_\text{bonus} = C_{41 cm BB} \times \sqrt{N_{41 cm}} + C_{IJN 41cm Twin Nagato Kai Ni} \times \sqrt{N_{IJN 41cm Twin}} + C_{51cm} \times \sqrt{N_{51cm}} = ( 2 + 4 - 5 ) \times \sqrt{1} = +1.00 }[/math]
  • If Nagato Kai Ni is married, the M multiplier is applied to the -5 only in this case.


Musashi Kai Ni equiped with 1 IJN 51cm Twin51cm Twin Gun Mount and 1 IJN 51cm Triple ProtoPrototype 51cm Triple Gun Mount

  • [math]\displaystyle{ \text{ACC}_\text{bonus} = C_{51 cm Musashi Kai Ni} \times \sqrt{N_{51 cm}} = 0 \times \sqrt{2} = +0.00 }[/math]
  • Musashi Kai Ni has 99 bases Health, and so has bonuses set to ZERO for those guns.


Yamato Kai Ni Juu equiped with 1 IJN 46cm Triple46cm Triple Gun Mount and 1 IJN 51cm Triple ProtoPrototype 51cm Triple Gun Mount

  • [math]\displaystyle{ \text{ACC}_\text{bonus} = C_{46 cm Triple Yamato-class} \times \sqrt{N_{46 cm Triple}} + C_{46/51 cm Yamato Kai Ni Juu} \times \sqrt{N_{46/51 cm}} = 7 \times \sqrt{1} + (-8) \times \sqrt{2} = -4.31 }[/math]
  • If Yamato Kai Ni Juu is married, the M multiplier is applied to the -8 only in this case.

Certain destroyers receive some Accuracy Accuracy bonuses when equipped with certain guns or sonars. The resulting accuracy bonus is:

Fit Formula
[math]\displaystyle{ \text{ACC}_\text{bonus} = \sum^{\text{All Groups} } C_{Group} \times \sqrt{N_{Group} } }[/math]
With
  • [math]\displaystyle{ \text{All Groups} }[/math] the equipment groups defined in the following table.
  • [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.

  1. 2x base 5" Gun5inch Single Gun Mount Mk.30 on Fletcher-class gives ~10 accuracy. This is potentially a bug.
  2. Samuel B.Roberts does not seem to receive any bonus from base 5" Gun5inch Single Gun Mount Mk.30. This is possibly a bug (maybe related to the bug on Fletcher-class).
  3. There are not enough samples on more than one ASDICsType124 ASDIC

    sonar so it is not clear how does the accuracy bonus scales. This bonus can stack with the accuracy bonus from QF 4.7inch Gun Mk.XII KaiQF 4.7inch Gun Mk.XII Kai.
