==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.
  
'''Submarines''' ([[SS]], also including '''"Aircraft Carrying Submarines"''' [[SSV]]) are characterized by relatively low armor and HP. By contrast, they are difficult to handle using "normal setups", requiring instead specific '''Anti-Submarine Warfare (ASW)''' equipment and setups in order to be sunk.

During sorties, submarines are typically found at pre-boss nodes, but some can be boss themselves, see ''[[Enemy#Bosses (SS)|here]]''.

===ASW attack conditions===
 
Only certain ships meeting certain conditions can attack SS(V).

==Damage calculation==
+
===Landing Craft Specific Bonuses===
The stats used to calculate damage against submarines is the {{ASW}} ASW.
+
The following multipliers are '''pre-cap'''.
*When contributing to ASW power, Base {{ASW}} ASW is '''square rooted''', while equipment ASW is '''multiplied by 1.5'''
 
**[[:Category:Anti-submarine Weaponry|Anti-submarine weaponry]] is therefore the primary source of ASW damage, with the base ship ASW playing a very minor role damage-wise.
 
**However, base ship ASW is the primary determinant of whether a ship can reach 100 total ASW to perform '''"[[#Opening ASW Shelling (OASW)|Opening ASW]]"''' (OASW) attacks.
 
*Unlike sheeling, ASW damage is capped at 170.
 
ASW attacks have different modifiers gained from [[Formation]]s,
 
*{{ToolTip|[[Combat#Formation_Selection|Line Abreast]]|[[File:LineAbreast.png]]}} is the main ASW formation, with a 1.3x damage modifier,
 
*{{ToolTip|[[Combined_Fleet#Formation_Selection|Cruising Formation 1]]|[[File:Formation_1.png]]}} is the main ASW formation for [[Combined Fleet]]s, with a 1.3x damage modifier.

==Equipment Set Up==
+
====Rations Bonuses====
Are listed here some recommended equipment setups for ASW duties. ''The equipment order is illustrative and does not reasonably matter.
+
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>.
As general rules:
 
*The first priority is to have OASW, even at the expense of synergy:
 
**[[DE]] can OASW more easily than [[DD]],
 
**Because {{ASW}} increase with levels using high-level ships can help,
 
**Take note that DEs have bonus armor penetration from Depth Charges.
 
*To further maximize ASW effectiveness, regardless if an OASW is triggered or not, it is recommended to use:
 
**{{Small Sonar}} {{DCP}} {{DCR}}
 
*When using carriers, it is recommended to use [[CVE]], as they have a base {{ASW}} stat.

! colspan=2| Installation Type
| This ASW setup maximizes the ASW by taking advantage of the synergy. One of the depth charges needs to be a [[DCR|Depth Charge Projector]] while the other needs to be a [[DCR|Depth Charge (Racks)]]. Take note that '''reaching the [[OASW]] threshold takes precedence over everything'''. So you should just replace depth charges with equipment that has better ASW if you cannot hit the threshold with this setup.

 +
*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.
  
==LBAS==

===Airstrike And Land-Base Bonus===
''See the [[Land-Based Air Squadron#Attack Power|Land-Based Air Squadron]] page
+
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%.
*Only [[ASW Aircraft|ASW Planes]] (7+ {{ASW}} ASW) can attack submarine during this phase.
 
**If submarines are present, those planes will prioritize attacking submarines, while other attackers will only be able to attack surface targets.
 
{{Category:ASW Aircrafts}}
 
  
==ASW Support Expedition==
+
There are exceptions:
''See [[Support Expedition#Anti-Submarine Support|ASW Support Expedition]]
+
*For {{BluePlane}} [[Torpedo Bomber]]:
* If a CVL is present, aircraft with {{ASW}} ASW will attack submarines regardless of the ship on which it's equipped.
+
** The {{torpedo}} torpedo stat is counted as 0 in airstrike,
 +
** The behavior is unclear for LBAS (the damage are overestimated).

Latest revision as of 16:35, 23 March 2024

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

[math]\displaystyle{ \text{Atk}_\text{cap} = \text{Cap} + \sqrt{\text{Atk}_\text{pre-cap} - \text{Cap}} }[/math]

[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

  • A & C the Multiplicative bonuses,
  • B the Flat bonuses,
  • A & B being pre-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   bombing stat of Anti-installation Dive Bomber only
  • [math]\displaystyle{ \text{Cap} }[/math] is:
    • 220 during day,
    • 360 during night.

  5. In this case the Ka-Tsu Kai count as two, 1 Ka-Tsu Kai = 1.2

Post-Cap Bonuses

Supply Depot Princess

Supply 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.

  2. For example: 1 Chi-Ha  = no bonus, 2 Chi-Ha  = 1.6, 1 T89  + 1 Chi-Ha  = 2.08 (1.3x1.6)
  3. In this case the Ka-Tsu Kai count as two, 1 Ka-Tsu Kai = 1.2

Rations Bonuses

The developers have mentioned that   Rations 
 
 
consumed by a girl "affect landing craft's morale"[1].

C1
Installation Type All installations[2]
Number Equipped Single Multiple
  Combat Ration  1.13 ??
Combat Ration (Special Onigiri)  ?? ??
Canned Saury  ?? ??
Notes
  • A   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:
    • The   torpedo stat is counted as 0 in airstrike,
    • The behavior is unclear for LBAS (the damage are overestimated).
  • For    Jets 
     
    :
    • 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].
