==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<ref>https://docs.google.com/document/d/1mXGyJ3yeNWeOmuGZQrXkcuGSuSEQYqmKhPelHMkzkGI/edit</ref>:
 +
# [[#Ship Type Bonuses|Ship type bonuses]],
 +
# [[#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.

This page lists all the applicable damage formulas for a '''single fleet'''. Special cases like [[Combined_Fleet#Damage_Calculations|Combined Fleet]]s and [[Land-Based_Air_Squadron#Attack_Power|Land-Based Air Squadron]]s have their own adjustments to the standard damage formulas. Please see those pages for further details.

−
 
 
−
'''Notes:'''
 
−
* The caliber of the gun does not affect damage.
 
−
* Abyssal installations that are not equipped with a plane that has a torpedo or dive bombing stat will use the surface shelling formula for calculating damage.

===Carrier Attacks===
 
−
 
 
−
<math>\text{Power}_\text{carrier} = \bigl\lfloor \left( \text{FP} + \left(\text{TP} + \bigstar \right) + \lfloor \text{DB} \times 1.3 \rfloor + \bigstar \right) \times 1.5 \bigr\rfloor + 55 </math>
 
−
 
 
−
'''Notes:'''
 
−
* Dive and Torpedo groups contribute, respectively, 1.95 and 1.5 times their dive bomb and torpedo stats towards shelling power
 
−
* Torpedo Stat from fit does not contribute to shelling damage
 
−
* If a carrier is not equipped with any torpedo or dive bombers, she will not participate in shelling.
 
−
** This also applies if they have lost all bombers during the aerial combat phase.
 
−
** But even if an air group has had all its planes shot down, it will still contribute towards carrier shelling power (if the CV is still capable of attacking).
 
−
* Remember that there are potentially two sources of <math>\bigstar</math> bonuses.
 
−
** Torpedo bomber upgrades to the torpedo stat.
 
−
** Secondary and machine gun upgrades to the firepower stat.
 
−
* Slot sizes and the number of remaining aircraft '''do not affect''' carrier attack power during shelling.
 
−
* Carriers have the easiest time hitting the damage cap. This makes them very powerful assets for the fleet.
 
−
* Abyssal installations equipped with a plane that has a torpedo or dive bombing stat will use the carrier formula for determining shelling damage.
 
−
* Planes are '''not shot down''' when a carrier participates in shelling

;Notes
 
−
* Carriers must be equipped with a [[NOAP]] or [[NOAP+]] in addition to "[[Night Plane]]s", in order to perform carrier night attacks.  
 
−
**{{Category:Night Carriers}}
 
−
* If the carrier night attack is evaded, it deals [[#Scratch Damage|scratch damage]] instead.
 
−
* Unlike daytime carrier attacks, it is possible to attack even if no bombers are equipped.
 
−
** Night fighters are still needed to trigger the attack.
 
−
* Like daytime carrier attacks, carriers are unable to attack if moderately damaged or worse.
 
−
** Armored carriers are only disabled at heavy damage.
 
−
** Carriers that can use the night battle shelling formula will use that instead if moderately damaged.
 
−
* The formula '''only takes into account the base stats of the carrier and night attack capable planes equipped'''.  
 
−
** The [[Improvement]] stats are not taken into account.
 
−
*** This means any other stats and upgrade bonuses from equipment like guns and non-night-capable planes are ignored.
 
−
** This also means that any [[Visible Bonus]] from Planes is also ignored.
 
−
*** The [[Visible Bonus]]es given by the [[SDP+]] are whoever counted here.
 
−
* Certain carriers (see [[#Surface_Night_Battle|here]]) are capable of performing night attacks but they '''are not''' carrier night air attacks and are just normal shelling attacks. Please see [[Night Battle#Carrier_Night_Attacks|Carrier Night Attacks]] for more details.
 
−
 
 
−
===Anti-Installation Attacks===
 
−
Installations differ from regular enemy warships, as they are immune to certain attack elements like the torpedo stat, but are extremely weak against specialized gears.
 
−
*''See the [[Combat/Anti-Installation#Damage Calculation|Anti-Installation]] page for more details.
 
−
 
 
−
=Attack Power Corrections=
 
−
 
 
−
After calculating the basic attack power of the attack being made, it is then adjusted based on various factors. Attack power modifiers can be split into pre- and post-cap modifiers. Post-cap modifiers are more powerful to have because they aren't reduced by the cap.
 
−
 
 
−
==Attack Power Cap==
 
−
The attack power cap varies depending on the phase of combat it is in.

===Armor-Piercing Modifier===
+
====Rations Bonuses====
−
During day combat, certain enemy ships take extra damage from {{RedAmmo}} {{Equipment/Link|Type 91 Armor Piercing Shell|Type 1 Armor Piercing Shell|Type 1 Armor Piercing Shell Kai|text=AP Shells|link_category=Armor Piercing Shells}}.
+
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>.
−
* The bonus only applies against [[FBB]], [[BB]], [[BBV]], [[CV]], [[CVB]], [[CA]], and [[CAV]].
 
−
** This includes [[Installation]]s.
 
−
** This means that this bonus does not apply against all other types, namely CVL, CL(T), CT, DD, DE, SS(V), AV, AS, AR, LHA, or AP.

;Notes:
 +
*A {{LandingCraft}} [[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.
  
−
;Note
+
===Airstrike And Land-Base Bonus===
−
*It is '''unadvisable''' to run any of the other setups beyond the most basic Gun+AP, as the other setups will interfere with artillery spotting and give worse bonuses.
+
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%.
  
−
===Anti-Installation Equipment Modifiers===
+
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).
  
−
See the [[Combat/Anti-Installation#Damage Calculation|Anti-Installation]] page.
+
*For {{JetFighterBomber2}}{{JetFighterBomber1}} {{EquipmentLink|Kikka Kai|Jet Keiun Kai|text=Jets|link=Jets}}:
 +
** There are inconsistencies with the bonuses.
  
−
===Critical Strikes===
+
*For the {{Large Land-based Aircraft}} {{Equipment/Link|Shinzan|Shinzan Kai|text=Land-Based Heavy Bombers|link_category=Land-Based Heavy Bombers}}:
−
For more details on how critical chance is calculated, please see [[Accuracy, Evasion and Criticals#Critical Strikes|Accuracy, Evasion and Criticals]].
+
** Could have a higher modifier than other planes.

====Plane Proficiency Critical Modifier====
+
===Installation-Like Warships===
−
Carriers get a bonus critical modifier when equipped with high proficiency planes. This modifier is multiplicative with the normal critical modifier. For more details, please see [[Plane Proficiency#Critical Bonus|Plane Proficiency]]
+
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<ref>Updated the 08/09/2022 during the [[Summer 2022 Event]] [https://nga.178.com/read.php?tid=33769345&rand=329].</ref>.
  
−
* For '''Carrier Attacks''', they gain a '''1.2''' critical bonus multiplier for a {{Double Chevron}} plane in the top slot and an additional '''0.1''' for every other {{Double Chevron}} plane.
+
{|class="wikitable mw-collapsible mw-collapsed" style="font-weight:bold; text-align:center"
−
** For example, a carrier with two max proficiency planes (with one in the top slot) would get a critical bonus of: '''(1.2 + 0.1) x 1.5 = 1.95'''.
+
! colspan=9|Installation-like warships
−
* For '''[[#Carrier_Cut-In_Attacks|Carrier Cut-In Attacks]]''', they gain a '''1.106''' bonus when a {{Double Chevron}} plane is selected to participate in the attack and an additional '''+0.15''' if one of the selected planes is in the top slot.

If a special attack is evaded, the target's armor cannot be penetrated, or the ammo count hits 0; attacks will deal '''"scratch damage"''' instead, also called '''"chip damage"'''.
 
−
*Scratch damage is dealt as a percentage of remaining HP calculated using the following formula:
 
−
 
 
−
<math>\text{scratch} = \text{HP}_\text{current} \times 0.06 + \text{HP}_\text{rand} \times 0.08 </math>
 
−
 
 
−
* <math>\text{HP}_\text{current}</math> is the current HP of the target.
 
−
* <math>\text{HP}_\text{rand}</math> is a random HP number between 0 and <math>\text{HP}_\text{current} - 1</math>
 
−
 
 
−
Therefore the maximum possible scratch damage <math>\text{HP}_\text{current} \times 0.14 - 0.08</math> and the minimum damage is <math>\text{HP}_\text{current} \times 0.06</math>. Meaning scratch damage is generally between '''6-14% of current HP'''.
 
−
 
 
−
* If the target's HP is low, it is possible for the result of the formula to return a result of 0. Remember that all formulas are rounded down.
 
−
** This means the target's HP cannot be reduced to 0 by scratch damage.

===Historical Bonus===
 
−
On almost every [[Event]] map, as well as some regular maps ([[7-4]] & [[7-5]] so far), certain ships, types of ships, equipment, or types of equipment will bring bonuses.
 
−
*Those bonuses are most of the time raw damage multipliers, and sometimes, accuracy bonuses.
 
−
*Bonuses are independent to each ship, so only the ships with any historical bonus or ships equipped with historical equipment will be affected.
 
−
*Bonuses may be applicable to some part of a map only, such as specific phases of nodes.
 
−
 
 
−
This mechanic is here to encourage the use of "historically significant fleets and setups".
 
−
*By nature, historical bonuses are arbitrary, so refer to each individual map to see what bonuses are applicable.
 
−
 
 
−
===[[Debuffs]]===
 
−
Debuffs are a special case that only applies during events. Certain event maps have debuff mechanics that require meeting certain conditions to trigger them. Debuffs can be either a reduction to the enemy's armor or a post-cap damage modifier for the fleet.
 
−
 
 
−
'''Notes:'''
 
−
* Debuffs are affected by the remaining ammo modifier.
 
−
 
 
−
=Overkill Protection=
 
−
When a ship in the fleet takes more damage than her current HP, she will take a percentage of her current HP in damage instead.
 
−
* The ship must be the flagship OR
 
−
* The ship must not be heavily damaged nor red morale at the start of the battle.
 
−
** If the ship has red morale, she will just have her HP reduced to 1.
 
−
 
 
−
<math>\text{Overkill} = \text{HP}_\text{current} \times 0.5 + \text{HP}_\text{rand} \times 0.3 </math>
 
−
 
 
−
* <math>\text{HP}_\text{current}</math> is the current HP of the ship.
 
−
* <math>\text{HP}_\text{rand}</math> is a random HP number between 0 and <math>\text{HP}_\text{current} - 1</math>
 
−
 
 
−
Therefore, the maximum damage from overkill protection is <math>\text{HP}_\text{current} \times 0.8 - 0.3</math> and the minimum damage is <math>\text{HP}_\text{current} \times 0.5</math>. Meaning overkill protection will take off between '''50-80% of the ship's current HP'''.
 
−
 
 
−
'''Important Information'''
 
−
* In general:
 
−
** Overkill protection is most applicable to DDs.
 
−
*** The most pronounced effects of overkill protection occur at low HP
 
−
*** It is also the primary means of surviving a hit they fail to evade
 
−
*** For example, a 32HP DD has a 15.5% chance of being heavily damage by a BB hime, while a 31 HP DD has just a 6.5% chance
 
−
*** This has great implications when marrying ships, 36 HP has one of the highest chances of a taiha
 
−
** Odd numbered HP is better when overkill protection is triggered. This is because the damage calculations round down, reducing the likelihood of being knocked down to heavy damage.
 
−
** This mechanism is most applicable to ships '''at full HP'''. Once a ship starts taking damage, the utility of overkill protection diminishes
 
−
* As a rule, ships with HP that is divisible by 4 have worse survivability.

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.

Supply Depot Princess

Supply Depot PrincessSupply Depot Princess and its variants are currently the only installations to have post-cap bonuses.

  • These bonuses are applied after the damage soft-cap, and can reach the damage display cap of 9999.
    • If the damage displayed is 9999, the actual damage can be higher.
  • Supply Depot Princess is a soft-skinned installation for purposes of Pre-Cap Bonuses.

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].
