'''Installations''' are an enemy-type representing "land-based installations", and are characterized by high armor and high HP. They are difficult to handle using normal anti-ship setups and require specific setups in order to be destroyed. Installations are typically found as bosses or as boss escorts.
+
Anti-Submarine Warfare
  
=General Characteristics=
+
*Submarine are immune by air and torpedo attack.
* Installations cannot perform or benefic from flagship protection.
+
*They cannot be targeted by normal shellign attack
* They have different damage statuses instead of the normal ones used for ships.
+
*They can only be damaged by ASW attacks
 +
*They cannot be sink at night in single fleet, only a combine fleet can.
 +
** Friendly Fleet can sink submarine (at night)
 +
** wikiwiki mention that "開幕夜戦マス" can sink sub at night
 +
*ASW attacks is the only to have a damage modifier above 1 with some formation(Diamond, Echelon, Line-Abreast)

|}
 
*Please note that event only installation might not be in one if these category.
 
 
 
=Attack Behavior=
 
The targeting of installation follow some special rules.
 
 
 
===Suport Expedition===
 
* Shelling Support expedition can attack Instllation.
 
*It's unknown if torpedo support and ASW support will target installaion or not.
 
 
 
===Air strike===
 
* ''Normal'' dive bombers can '''not''' attack installations during the air strike phase.
 
* Only '''Anti-installation Dive Bombers''' can target installation.
 
* It's unknown if ASW plane will prioritize Submarine or installation.
 
{{Category:Anti-Installation Dive Bombers}}
 
 
 
===Shelling===
 
* Submarines can attack installations during shelling if equipped with a {{EquipmentLink|Special Type 2 Amphibious Tank}}.
 
** They will only target instllation during the shelling.
 
** They will be able to attack installations at night regardless of equipment.
 
** Their low firepower makes them poor anti-installation ships.
 
* Carriers are '''unable to perform [[Combat/Artillery Spotting#Aircraft Carrier Cut-in|CVCI]]''' on installations, even if equipped with anti-installation dive bombers.
 
* [[Ise]] and [[Hyuuga]] can perform the suisei-CI against installation with any Dive Bombers.
 
*[[Special Attacks]] behave like normal against installation.
 
 
 
===Torpedo===
 
* Both opening and closing torpedoes can '''not''' target installation.
 
** Opening and closing torpedoes will fail to trigger if only installation targets remain.
 
 
 
===Nitght Battle===
 
* The torpedo stat is '''ignored''' when calculating night battle damage against installations. Please see [[Night Battle]] for more details.
 
** This makes destroyers, light cruisers, and heavy cruisers much weaker unless equipped with anti-installation equipment.
 
* When targeting installation the Cut-in choice will ignore any equiped torpedo.
 
** Except Special DD Cut-in that include a main gun (torpedo stat is still considered equal to 0).
 
* Night shelling Carrier willl behave like normal surface ship.
 
** This include [[Ark Royal]]'s night swordfish attack.
 
* Air night attacks ignore all anti-installation bonus
 
** The attack can target installation even if no anti-anstallation dive bombers is equiped
 
 
 
=Damage Calculation=
 
 
 
* During day, damage is capped at 220 so any ship with a proper anti-installation setup will be able to hit the cap.
 
** When facing hard-skinned installations, it is better for battleships to have AP shells instead of Type 3 because they will hit the day cap anyway.
 
* Anti-installation is very important during night battle when the cap is raised to 360.
 
* Torpedo stat is always counted as 0 when attacking installations. This applies to both airstrikes and night battles.
 
** However improvement that give "Yasen" is taken into account.
 
* [[Supply Depot Princess]] is the only known installation that takes post-cap damage from anti-installation equipment.
 
** This makes her vulnerable to getting one shot by nuke setups. See [[#Equipment Setups|below]] for details.
 
* While dive bombers have a post-cap bonus during the air-strike, the low base damage means it is of limited effectiveness against high armor installations.
 
* The Armor Percing modifier (post-cap) is effective against installation.
 
 
 
==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]]

# [[#Specific equipment bonuses|Specific equipment bonuses]]:
 
## 11th regiment bonuses
 
## M4A1 bonuses
 
## Ho-Ni bonuses
 
## Landing craft synergy bonuses
 
# [[#Flat Damage Bonuses|General Flat bonuses]]
 
# [[#Post-Cap Bonus|Post-cap bonuses]] against {{Enemy/Link|Supply Depot Princess}}
 
 
 
*The order of bonuses is still being researched so it might change in the future

* Because the Ho-Ni isn't improvable the best bonus is x1.21
 
** this mean adding a Ho-Ni with a max t89 tank doesn't affect the improvement bonus.
 
*The improvement bonus with panzer need another Landing Craft.
 
** Because the panzer cannot be improved the best bonus is x1.331
 
* The bonus for the panze against known installation is identical to the t89 tank. For that reason it's speculated that it ''might'' get better bonus in event or against new installation (in africa for exemple).

=Equipment Setups=
 
Bellow are recommended equipment setups for anti-installation. ''The equipment order is illustrative and does not matter much.''
 
 
 
As a general rule if there is:
 
*One Anti-Ground Artillery {{AntiGroundArtillery}} equiped use a WG42
 
*Mutiple Anti-Ground Artillery {{AntiGroundArtillery}} equiped use Shipborne Model Type 4 20cm Anti-ground Rocket Launcher (or CD)
 
"{{TextGlow|'''Nuke'''|black|text-colour=lime|glow-size=2px}} setups" describe any setups using at least 1 {{Equipment/Link|WG42 (Wurfgerät 42)|Shipborne Model Type 4 20cm Anti-ground Rocket Launcher|Type 4 20cm Anti-ground Rocket Launcher (Concentrated Deployment)|text=Anti-ground Rocket Launcher|link_category=Anti-Ground Artillery}} {{AntiGroundArtillery}}, 1  [[:Category:Landing Craft|Landing Craft]] {{LandingCraft}}, and 1 {{EquipmentLink|Special Type 2 Amphibious Tank|text=Tank}} {{Amphibious Tank}}.
 
*Such setup has a powerful anti-installation power against all installations but is hampered by the daytime damage cap.
 
*It can be further improved by using more of those types of equipment when applicable.
 
*It performs best at night or when up against [[Supply Depot Princess]], where it can deal up to {{TextGlow|'''9999 damages'''|black|text-colour=gold|glow-size=2px}}!
 
*Using a {{EquipmentLink|Special Type 2 Amphibious Tank|text=Tank}} {{Amphibious Tank}} or a Landing Craft with specific bonus instead of a ground rocket give a better nuke however it's adviced to do a second Nuke instead.
 
 
 
All the "surface" anti-installation setups can be further enhanced by using them in '''[[Special Attacks]]''', especially [[Nelson]]'s Touch.

Revision as of 08:31, 4 August 2022

Anti-Submarine Warfare

  • Submarine are immune by air and torpedo attack.
  • They cannot be targeted by normal shellign attack
  • They can only be damaged by ASW attacks
  • They cannot be sink at night in single fleet, only a combine fleet can.
    • Friendly Fleet can sink submarine (at night)
    • wikiwiki mention that "開幕夜戦マス" can sink sub at night
  • ASW attacks is the only to have a damage modifier above 1 with some formation(Diamond, Echelon, Line-Abreast)

LBAS

  • LBAS plane with 7 or more Anti-Submarine Warfare ASW can attack submarine durinth this phase

Support

  • If a CVL is present, plane with Anti-Submarine Warfare ASW will attack submarine

OASW

  • Ever ship that can attack submarine can under some condition perform an Opening ASW attack
    • this is very important for multiple reason:
      • this add an ASW attack
      • this allow to sink Submarien before they do O-torp
      • this allow to kill the sub before other ship not equiped with ASw set-up target it

Shelling

  • Ship that can target submarine will prioritize the submarine
    • Kumano and Suzuya being the exception
Ship type Specific ship Condition Day Battle Night Battle
DE DD CL(T) CT AO? All at least 1 base Anti-Submarine Warfare ASW prioritize SS
AV CAV BBV LHA All SPB RotorCraft Flying Boat Carrier bomber with ASW prioritize SS Don't attack SS
CVL All ?? prioritize SS Nigth Air Attack cannot target SS
Suzuya Carrier Kai Ni Kumano Carrier Kai Ni prioritize surface target
Kaga Kai Ni Go prioritize SS prioritize SS with night shelling
Other ship type Cannot attack SS

Armor Penetration
Indepentant of synergies, some equipment provides additional armor penetration to ASW attacks.

The flat armor penetration value is calculated as follows:

[math]\displaystyle{ \text{Pen} = \sum\limits_{\text{Equipment}} \Big( \sqrt{\text{ASW}_\text{Equipment} - 2} + \text{Mod}_\text{ship} \Big) }[/math]
With
  • [math]\displaystyle{ \text{ASW}_\text{Equipment} }[/math] the base ASW Anti-Submarine Warfare stat of the applicable equipment,
  • [math]\displaystyle{ \text{Mod}_\text{ship} }[/math] being 1 for DE, 0 otherwise,
Note
  • Armor penetration from equipment stacks,
  • The final armor of the targetted submarine cannot go below 1.


  • The bonuses do not stack, meaning only the highest possible bonus applies.
    • The exception is when using the special depth charge projectors detailed above.
  • Multiple equipment of the same type still only apply the bonus once.
  • There is an accuracy bonus as well but it is small. Stacking sonars will give a bigger accuracy bonus.

Notes:

  • When contributing to ASW power, Base ASW is square rooted, while equipment ASW is multiplied by 1.5
    • ASW equipment is therefore the primary source of ASW damage, with base ASW playing a very minor role.
    • However, base ASW is the primary determinant of whether a ship can reach 100 total ASW to perform opening ASW attacks.
  • Submarines cannot take more than scratch damage at night (and therefore cannot be sunk).
    • The exception to this rule is when a battle starts at night, or when in a combined fleet
  • It is possible to perform opening ASW attacks when certain conditions are achieved. For more details, please see Opening Anti-Submarine Warfare (OASW).
    • As performing an opening attack effectively doubles the damage output, reaching this OASW threshold is in general more important than tacking on additional synergy.
