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.

General Characteristics

  • They have different damage statuses instead of the normal ones used for ships.

Installation Classification

Installations are classified by two categories: Ship Type (BB, BBV, CV) and Toughness (Soft Skin or Hard Skin).

Ship Type

Type Characteristics
Battleship (BB) Examples are Artillery Imps  and Central Princess .
  • Uses the surface shelling formula for calculating damage.
  • Uses the shelling attack animation in day and night battle.
  • Can continue attacking when moderately damaged.
Aviation Battleship (BBV) Most installations fall under this category.
  • Uses the carrier attack formula for calculating damage.
  • Uses the shelling attack animation in day and night battle.
  • Cannot attack during the day if heavily damaged or if there are no planes left.
  • Forced to attack submarines if they have equipment with  Anti-Submarine stat.
Carrier (CV) Example is Lycoris Princess .
  • Uses the carrier attack formula for calculating damage.
  • Uses the carrier attack animation in day battle and the shelling animation at night.
  • Cannot attack during the day if moderately damaged or if there are no planes left.
  • Do not enable the 2nd shelling phase if there is no battleship present.

Skin Toughness

Type Characteristics
Soft Skin Examples are Supply Depot Princess , Harbour Princess  and Northern Princess .
  • Takes a lot of damage from  Anti-Aircraft Shells 
     
    and less from other Anti-Installation equipment.
    • This weakness allows battleships and heavy cruisers to easily deal with these installation types.
    • Still takes a decent amount of damage from other anti-installation equipment.
  • Supply Depot Princess  has extra Post-Cap modifiers.
Hard Skin Examples are Isolated Island Demon , Artillery Imp , and Harbour Summer Princess .

Attack Behavior

  • Support expedition can attack Instllation.

Air strike

  • Normal dive bombers will not attack installations during the air strike phase. (wikiwiki say otherwise need to be checked)
  Dive-Bombers that can attack installations
This is a segment from a bigger article. See Combat/Anti-Installation for details on Installation mechanics.

Carriers will only attack installations in the shelling phase if equipped with Torpedo Bombers or Anti-Installation Dive Bombers.

  • Additionally, carriers will attack installations if equipped with non-special dive bombers AND one of the special dive bombers below.
  • Any other dive bomber will completely disable shelling against installations even if the carrier has a torpedo bomber equipped.
  • This can be very useful to manipulate the targeting mechanic so the carriers attack important targets.

Shelling

  • Submarines can attack installations during shelling if equipped with a 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 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.

Torpedoes

  • They cannot be targeted by torpedoes.
    • 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 below for details.
  • Pairing rockets or mortars give better multipliers than using them individually. Eg. WG/WG instead of WG/T4.
  • 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

Installation generaly have a lot of HP and/or armor. But there is multiple different cumulative bonuses against them that allow to do massive damage. These bonuses are divided into 5 group and are calculated in the following order:

  1. Ship type bonuses
  2. General mutiplicative bonuses
  3. Specific equipment bonuses:
    1. 11th regiment bonuses
    2. M4A1 bonuses
    3. Ho-Ni bonuses
    4. Landing craft synergy bonuses
    5. General additive bonuses
  4. Post-cap bonuses against Supply Depot Hime

Equipment Setups

Below are recommended equipment setups for anti-installation. The order of the equipment is for illustrative purposes only. It does not matter what order the equipment are in.

BB/FBB/BBV
Equipment Setup Notes
     This setup is the basic setup for battleships. Because battleships can hit the damage cap easily, they do not benefit much from anti-installation equipment. The standard artillery spotting setup will allow them to be effective against all other targets including the installation.
     This is an option where you will be facing soft-skinned installations. Taking a Type 3 shell will limit the battleship's effectiveness against all other targets. Careful consideration must be made into whether it is worth it.
    
    
Nagato-class Kai Ni & Yamato Kai Ni Juu.
  • The landing craft/amphibious tank will make their Touch attacks deal significant damage to installation enemies. Keeping the seaplane, allows them to perform artillery spotting to maintain some effectiveness against other targets.
      Yamato-class Kai Ni & Ise-class Kai Ni
  • "Best of both worlds"
CA/CAV
     This is the standard anti-installation setup for all heavy cruisers. It allows them to artillery spot and deals decent damage against installations.
     This is an alternative setup only for aviation cruisers. It removes the ability to artillery spot for much more powerful anti-installation damage at night.
     "Nuke" setup, Mogami Kai Ni Toku only.
CL
    "Nuke" setup.
  • It has powerful anti-installation power against all installations but is hampered by the daytime damage cap. It performs best at night or when up against Supply Depot Princess.
     An alternative setup for 4-slot light cruisers. This preserves their ability to double attack at night while giving them significant anti-installation power.
DD
    "Nuke" setup.
  • It has powerful anti-installation power against all installations but is hampered by the daytime damage cap. It performs best at night or when up against Supply Depot Princess.
   
   
This is an alternative setup that preserves their ability to double attack at night while maintaining decent anti-installation power. This setup works best if the Landing Craft or Amphibious Tanks are upgraded to maximize damage. It also allows them to perform well against non-installation targets at night.
   
   
"mini-Nuke" setup.
  • If you are lacking Landing Craft or Amphibious Tanks. It will still deal significant damage to Supply Depot Princess.
     Tashkent only.
  • Functions much like the light cruiser setup with a powerful night battle double attack.
CV/CVB/CVL
     This is only to be used if you have one of the anti-installation dive bombers. It will allow the carrier to still perform CVCI against other targets.
     The numbers of torpedo bombers and fighters in this setup can be varied depending on the amount of fighter power required. This is the standard carrier anti-installation setup. While it does sacrifice CVCI, the carrier shelling formula and proficiency bonuses still ensure that carriers will do significant damage to installations and other targets.
     Gambier Bay Mk.II & Unyou Kai/Ni only.
AV
     "Nuke" setup.
  • For 4-slot AVs, they can either take a 2nd anti-ground rocket or a seaplane fighter as the wild card. It has powerful anti-installation power against all installations but is hampered by the daytime damage cap. It performs best at night or when up against Supply Depot Princess.
LHA
     "Nuke" setup.
    +  "Nuke" setup, Shinshuu Maru Kai only.

Attack Animation

Somme Anti-installation equipemnts will change the attack animation. There is no relation between the presence/abscence of animation and the presence/abscence of anti-installation damage bonus.

  • rocket animation:W42, gruond rocket, ASW mortar
  • Landing craft:animation

These animation will be override by:

  • Artillery spoting
  • Night cut-in
