Introduction

Installations are an enemy type in game that is characterized by high armor and high HP. They are difficult to handle using normal anti-ship setups and require specific setups in order to destroy. Installations are typically found as bosses or as boss escorts.

General Characteristics

  • They cannot be targeted by torpedoes.
    • Opening and closing torpedoes will fail to trigger if only installation targets remain.
  • 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.
  • Submarines can attack installations during shelling if equipped with a Special Type 2 Amphibious Tank .
    • They will be able to attack installations at night regardless of equipment.
    • Their low firepower makes them poor anti-installation ships.
  • Only dive bombers will attack installations during the air strike phase.
  Dive-Bombers that can attack installations

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.

  • Carriers are unable to perform cut-ins on installations, even if equipped with anti-installation dive bombers.
  • 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 .

Damage Bonuses

Please see Damage Calculations for more details on how anti-installation damage is calculated.

  • 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.
  • 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.

Equipment Setups

Below are recommended equipment setups for anti-installation. If a setup is not listed, it means that it is subpar and not worth considering. The order of the equipment is for illustrative purposes only. It does not matter what order the equipment are in.

Battleships
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.
    /  An alternative setup for Nagato Kai Ni and Mutsu Kai Ni. 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 effectivenes against other targets.
      This is a unique setup available to Musashi Kai Ni that allows her to have the best of both worlds.
Heavy Cruisers
Equipment Setup Notes
     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.
Light Cruisers
Equipment Setup Notes
    This is the standard "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.
Destroyers[1]
Equipment Setup Notes
    Same as the "nuke" setup used by light cruisers. 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 maximise damage. It also allows them to perform well against non-installation targets at night.
 /    An alternative "nuke" setup if you are lacking Landing Craft or Amphibious Tanks. It will still deal significant damage to Supply Depot Princess.
     This setup is currently unique to Tashkent. It functions much like the light cruiser setup with a powerful night battle double attack.
Carriers/Light Carriers
Equipment Setup Notes
     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.
Seaplane Tenders
Equipment Setup Notes
     Same "nuke" setup used by light cruisers. 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.
  1. ↑ High-angle main guns can stand in for the small-caliber main guns.
