This page is to provide an in-depth look into the hit rate mechanics in-game for '''single/combined fleets and land-based air squadrons'''. The formulas presented in this page are still subject to change as more testing is done.  
+
==Calculation==
*'''Please note that all formulas between <math>\lfloor \ \rfloor</math> are rounded down.'''
+
Installations generally have a lot of HP and/or armor. But multiple different cumulative bonuses exist against them, allowing for massive damage when using the right set-ups.
 
+
These bonuses are divided into 5 groups and are calculated in the following order<ref>https://docs.google.com/document/d/1mXGyJ3yeNWeOmuGZQrXkcuGSuSEQYqmKhPelHMkzkGI/edit</ref>:
=Hit Rate=
+
# [[#Ship Type Bonuses|Ship type bonuses]],
The hit rate is used by all attacks.  
+
# [[#General Multiplicative Bonuses|General multiplicative bonuses]],
 +
# [[#Landing Craft Specific Bonuses|Landing craft specific bonuses]],
 +
# [[#Flat Damage Bonuses|Flat damage bonuses]],
 +
# [[#Post-Cap Bonuses|Post-cap bonuses]],
 +
# [[#Airstrike And Land-Base Bonus|Airstrike and land-base]] special cases,
 +
# [[#Installation-Like Warships|"Installation-like warships"]] special cases.
 +
*The bonuses' exact order is still under investigation and may be subject to changes.

'''Hit Rate Caps'''
 
 
There is a minimum and maximum hit rate in the game.
 
* The minimum of <math>\text{cap}_\text{min}\left(x\right)</math> '''is 10'''.
 
* The maximum of <math>\text{cap}_\text{max}\left(x\right)</math> '''is 96'''.
 
 
'''Notes:'''
 
* Hit rate has an effective '''minimum of 11%''' and a '''maximum of 97%'''.
 
* Plane proficiency is the only factor that allows a ship to go beyond 100% hit rate.
 
 
==Critical Hit Rate==

===Landing Craft Specific Bonuses===
* Because of the number of modifiers to accuracy in-game, it is trivial to increase accuracy. Therefore it is '''more important''' to prioritize firepower.

====Rations Bonuses====
* It is '''inadvisable''' to run any of the other setups beyond the most basic Gun+AP. This is because the other setups will interfere with artillery spotting and cost you better attack bonuses.

The developers have mentioned that {{Rations}} {{EquipmentLink|Combat Ration|Combat Ration (Special Onigiri)|Canned Saury|text=Rations|link_category=Ration}} consumed by a girl "affect landing craft's morale"<ref>https://twitter.com/KanColle_STAFF/status/715840109103484928</ref>.
* Unlike when calculating damage, the bonus applies to all targets.

===Airstrike And Land-Base Bonus===
!Aerial Combat
+
For the damage formula, please refer to the [[Land-Based Air Squadron#Attack Power|LBAS]] and [[Damage_Calculations#Airstrike|airstrike]] page. The multiplier is chosen randomly between two values. The chance is roughly 50%.
|-

This formula applies to the airstrikes performed during the aerial combat phase and support. Although ASW support functions like an airstrike for damage, it '''does not''' use this formula.
 
  
<math>\text{Accuracy}_\text{airstrike} = 95</math>

There are exceptions:
 +
*For {{BluePlane}} [[Torpedo Bomber]]:
 +
** The {{torpedo}} torpedo stat is counted as 0 in airstrike,
 +
** The behavior is unclear for LBAS (the damage are overestimated).
  
'''Important Notes'''
+
*For {{JetFighterBomber2}}{{JetFighterBomber1}} {{EquipmentLink|Kikka Kai|Jet Keiun Kai|text=Jets|link=Jets}}:
* Airstrike accuracy is a constant and '''not affected''' by any outside factors.
+
** There are inconsistencies with the bonuses.
  
==Anti-Submarine Warfare==
+
*For the {{Large Land-based Aircraft}} {{Equipment/Link|Shinzan|Shinzan Kai|text=Land-Based Heavy Bombers|link_category=Land-Based Heavy Bombers}}:
This formula applies to all ASW attacks in the combat phase and support.
+
** Could have a higher modifier than other planes.
  
<math>\text{Accuracy}_\text{ASW} = \left( 80 + 2 \times \sqrt{\text{Level}} + 1.5 \times \sqrt{\text{Luck}} + \sum_{\text{All Equips}} \text{Acc}_\bigstar + 2 \times \sum \text{ASW}_\text{sonar} \right) \times \text{Mod}_\text{formation} \times \text{Mod}_\text{morale} \times \text{Mod}_\text{synergy}</math>

Calculation

Installations generally have a lot of HP and/or armor. But multiple different cumulative bonuses exist against them, allowing for massive damage when using the right set-ups. These bonuses are divided into 5 groups and are calculated in the following order[1]:

  1. Ship type bonuses,
  2. General multiplicative bonuses,
  3. Landing craft specific bonuses,
  4. Flat damage bonuses,
  5. Post-cap bonuses,
  6. Airstrike and land-base special cases,
  7. "Installation-like warships" special cases.
  • The bonuses' exact order is still under investigation and may be subject to changes.
Damage Bonuses Calculations
Pre-cap

Surface Shelling:

[math]\displaystyle{ \text{Atk}_\text{pre-cap} = \Bigg[ \Bigg( \bigg[ \bigg( \Big[ \Big( \big[ \big( [ ( \text{Atk}_\text{base} {\color{tomato} \times \text{A0}} {\color{DeepSkyBlue} + \text{B0}} ) {\color{tomato} \times \text{A1}} {\color{DeepSkyBlue}} ] {\color{tomato} \times \text{A21}} {\color{DeepSkyBlue} + \text{B21}} \big) {\color{tomato} \times \text{A22}} {\color{DeepSkyBlue} + \text{B22}} \big] {\color{tomato} \times \text{A23}} {\color{DeepSkyBlue} + \text{B23}} \Big) {\color{tomato} \times \text{A24}} {\color{DeepSkyBlue} + \text{B24}} \Big] {\color{tomato} \times \text{A25}} {\color{DeepSkyBlue} + \text{B25}} \bigg) {\color{tomato} \times \text{A26}} {\color{DeepSkyBlue} + \text{B26}} \bigg] {\color{tomato} \times \text{A27}} {\color{DeepSkyBlue} + \text{B27}} \Bigg) {\color{tomato} \times \text{A28}} {\color{DeepSkyBlue} + \text{B28} + \text{B1}} \Bigg] \times \text{Mod}_\text{others} }[/math]


Carrier Shelling:

Cap
[math]\displaystyle{ \text{Atk}_\text{cap} = \text{Cap} + \sqrt{\text{Atk}_\text{pre-cap} - \text{Cap}} }[/math]
Post-Cap
[math]\displaystyle{ \text{Atk}_\text{post-cap} = \text{Atk}_\text{cap} \times \text{Mod}_\text{others} {\color{tomato} \times \text{C}} {\color{tomato} \times \text{C1} \times \text{Mod}_\text{Inst}} \times_\downarrow \text{Crit} }[/math]
With
  • [math]\displaystyle{ \text{Atk}_\text{base} }[/math] the base attack deffined here,
  • A & C the Multiplicative bonuses,
  • B the Flat bonuses,
  • A & B being pre-cap bonuses,
  • C being post-cap bonuses.
  • [math]\displaystyle{ \text{Mod}_\text{others} }[/math] being all other modifiers unrelated to installation (see Damage Calculations for more details)
  • [math]\displaystyle{ \text{DB} }[/math] being the Dive Bomber Attack bombing stat of Anti-installation Dive Bomber only
  • [math]\displaystyle{ \text{Cap} }[/math] is:
    • 220 during day,
    • 360 during night.

Notes
  • A Landing Craft Landing Craft might be required to be equipped on the attacking ship for this bonus to be applied.
  • As it is the only post-cap bonus common to all installations, it has a great potential.
  • Due to the limited nature of Rations, this bonus is mostly "Pay To Win", and so is not recommended.

Airstrike And Land-Base Bonus

For the damage formula, please refer to the LBAS and airstrike page. The multiplier is chosen randomly between two values. The chance is roughly 50%.

There are exceptions:

  • For Torpedo Bomber Torpedo Bomber:
    • The Torpedo Attack torpedo stat is counted as 0 in airstrike,
    • The behavior is unclear for LBAS (the damage are overestimated).
  • For JetFighterBomber2.pngJetFighterBomber1.png JetsKikka Kai
    Jet Keiun Kai
    :
    • There are inconsistencies with the bonuses.

Installation-Like Warships

This section is for special ships with installation-like behaviors, taking additional damage from anti-installation equipment.

  • Those bonuses are post-cap only, meaning none of the "anti-installation bonuses" previously mentioned are applied.
  • Be aware that the sample is limited (event only) so the information may be inaccurate and/or old[1].
