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

  • Installations cannot perform or benefit from flagship protection.
  • They have different damage statuses instead of the normal ones used for ships.
    • These statuses are merely cosmetic in nature and have no gameplay difference.

Installation Classification

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

Installations Glossary

Here is a list of all "Installation type Abyssals" ever encountered in the game.

  • Are listed the base forms of those installations, most coming in many variations often depending on the map difficulty, the map state (last-dance), and the event itself (most events bringing new variations).
    • Some installation sub-forms of interest are also listed, those forms having special variations like a different type than the main form, of some special abilities.
  • Note that some toughness characterization may be erroneous, since most of those installations were introduced before this system was defined.
    • Some event-only installations might not fall in one of these categories.

Ship Type
Type Characteristics
Battleship (BB)
  • Uses the surface shelling formula for calculating damage.
  • Uses the shelling attack animation in day and night battles.
  • Can continue attacking when moderately damaged.
Aviation Battleship (BBV)
  • Uses the carrier attack formula for calculating damage.
  • Uses the shelling attack animation in day and night battles.
  • Cannot attack during the day if moderately damaged or if there are no planes left.
  • Forced to attack submarines if they have equipment with Anti-Submarine WarfareAnti-Submarine stat.
Carrier (CV)
  • 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
  • Takes a lot of damage from Anti-Aircraft ShellAA ShellsType 3 Shell
    Type 3 Shell Kai
    Type 3 Shell Kai Ni
    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.
Hard Skin
Notes
  • The Northernmost Landing Princess is not immune to the Torpedo Torpedo Attack stat.
    • This means that during a Night Battles, the full "Night Battle Power" Night Battle Power is used to calculate damage against her.
    • She is still immune to torpedo-based attacks, which does not include airstrikes.
  • The Harbour Water Demon cannot attack during day battles when "moderately damaged" (like carriers).
    • Standard Night Battle rules still apply (she can attack even if moderately damaged).
  • Supply Depot Princesses have extra "Post-Cap modifiers", and can launch torpedo attacks.

Attack Behavior

The targeting of installation follow some special rules.

Support Expedition

  • Shelling Support expedition can attack installations.
  • It's unknown if torpedo support and ASW support will target installations or not.

Air strike

  • Air strikes can attack installations normally.

Shelling

Carriers can only attack installations if equipped with at least one anti-installation Dive Bombers with non-zero slot, or if equipped with only torpedo bombers (no dive bombers or jets).

  • Carriers equipped with no anti-installation Dive Bombers and at least one Normal dive bomber or jet with non-zero slot can not attack installations.
Dive Bomber 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.

Submarines can only attack installations during the shelling if equipped with Amphibious Tank Special Amphibious Tanks.

  • They will only target installations during the shelling phases.
  • 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.

"LST" type ships (No.101 Transport ShipNo.101 Transport Ship so far) will focus on installations if any are present.

Special Attacks behave like normal against installation.

In general, using dedicated "Landing Equipment" or other "Anti-Ground Equipment" is recommended to deal the most dame against installations:

Barrage Balloon Barrage Balloons

Torpedo

Opening Torpedo Salvos, Closing Torpedo Salvos, and Torpedo-based Cut-ins (like the TCI) cannot target installations.

  • Those attacks will fail to trigger if only installation targets remain.

Night Battle

  • The Torpedo Torpedo Attack 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 equipped torpedo.
    • This means a ship with 2 mains guns + 1 torpedo, which would normally perform Mixed Torpedo Cut-in on surface targets, would perform Double Attack on installations instead.
    • Exception for any DD Cut-ins: If the attacker has a main gun equipped, they can activate DD Cut-ins on installations, even if the main gun is not part of the cut-in's prerequisites (torpedo stat is still considered equal to 0).
  • Night shelling Carrier Attacks will deal damage like they would to ships.
    • This include Ark Royal's night swordfish attack.
  • Air night attacks ignore all anti-installation bonus
    • The attack can target installations even if no anti-installation dive bombers is equipped

Barrage Balloon

Example of a balloon deployed.

Barrage Balloon Barrage Balloons can be deployed in certain situations during day battles.

Barrage Balloons can only be deployed on certain combat nodes with Installations

Once deployed
  • For every ship with a balloon equipped will boost the damage of the fleet and the LBAS (post-cap):
Balloon Effects

Allied Day Shelling Damage
Allied balloons [6] 1.02 1.04 1.06
Allied LBAS Damage
Allied balloons [7] 1.02 1.04 1.06
Enemy balloons [8] 0.95 0.90 0.85
  • The effect stacks up to 3 balloons, and up to 1 balloon per ship,
  • The effect applies to LBAS and day shelling, with the enemy balloons also negatively affecting allied LBAS,
  • The effect does not apply to torpedo phases or night battles,
  • If the ship deploying it is sunk, the balloon is then removed, as well as its effects.

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 improvements that provide damage during Night Battle is taken into account during such.
  • 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 here 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 Piercing 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[1]:

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

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

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].

  • The animation of the Landing CraftArmed Armed BoatsArmed Daihatsu
    Soukoutei (Armored Boat Class)
    is also played against PT-ImpPT Imp Pack when equiped.
  • These animations will be overridden by:
    • Artillery spotting,
    • Night cut-in.
