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.

Ship Damage Label	Installation Damage Label
Lightly Damaged (小破)	Confused (混乱)
Moderately Damaged (中破)	Damaged (損害)
Heavily Damaged (大破)	Broken (損壊)
Sunk (撃沈)	Destroyed (破壊)

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.

	Those Abyssals are still considered surface ships, but receive bonus damage from anti-installation equipment, see here.

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 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 AA 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.
Soft Skin Supply Depot	Are all the standard "Soft Skin" property, with notably extra "Post-Cap modifiers", and can launch torpedo attacks. They are infamously weak to Nuke Setups , dealing damages in the thousands, potentially beyond the display cap of 9999.
Hard Skin	Takes more damage from Anti-Installation equipment like Landing Craft, Amphibious Vehicles and Anti-Ground Rockets

Notes

The Northernmost Landing Princess is not immune to the Torpedo stat.
- This means that during a Night Battles, the full "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).

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

Jet assault and 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.

Anti-Installation Dive Bombers
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.
Ju 87C Kai Prototype Nanzan F4U-1D FM-2 Ju 87C Kai Ni (w/ KMX) Ju 87C Kai Ni (w/ KMX/Skilled) Suisei Model 12 (634 Air Group w/ Type 3 Cluster Bombs) AAR Suisei Model 12 (w/ Type 31 Photoelectric Fuze Bombs) AAR Type 99 Dive Bomber Model 22 Type 99 Dive Bomber Model 22 (Skilled) SB2C-3 SB2C-5 F4U-4 AAR SBD (Yellow Wings) SBD VB-2 (Bomber Squadron) Prototype Myoujou (Additional Trial Model) Myoujou Kai Type 99 Training Bomber Model 22 Kai (Experimental w/ Night Equipment)

Submarines can only attack installations during the shelling if equipped with Amphibious Vehicles.

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.

Ise-class Kai Ni can still perform the Suisei-CI against installations.

"LST" type ships (No.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-Installation Equipment" is recommended to deal the most damage against installations:

Anti-Ground Equipment
Shells	Anti-Aircraft Shells
Shells	Armor Piercing Shells
Anti-Ground Artilleries	Anti-Ground Rockets
Anti-Ground Artilleries	Other ASW Mortars
Landing Craft	TP Transport Craft
	Tank Landing Tanks
	Armed Armed Boats
Amphibious Vehicles
Landing Forces
Seaplanes	Bomber Seaplane Bombers
Seaplanes	Seaplane Fighters
Anti-Installation Dive Bombers
Barrage Balloons
Rations

Torpedo

Opening Torpedo Salvos, Closing Torpedo Salvos, and Torpedo Cut-Ins cannot target installations.

Those attacks will fail to trigger if only installation targets remain.
Do note that the "Multiroll Cut-ins" (notably the TTL) are counted as "surface cut-ins" despite their torpedo animation, and so can target installations.

Night 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 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 Balloons can be deployed in certain situations during day battles.

Barrage Balloons can only be deployed on certain combat nodes (notably 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

Enemy Balloons [8]	0.95	0.90	0.85
Allied LBAS/Airstrike Accuracy
Allied Balloons	?	?	?
Enemy Balloons [9]	?	~0.8	?

The effect stacks up to 3 balloons, and up to 1 balloon per ship
The effect applies to LBAS, airstrike and day shelling, with the enemy balloons also negatively affecting allied LBAS and airstrike
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]:

Ship type bonuses,
General multiplicative bonuses,
Landing craft specific bonuses,
Flat damage bonuses,
Post-cap bonuses,
Airstrike and land-base special cases,
"Installation-like warships" special cases.

The bonuses' exact order is still under investigation and may be subject to changes.

Post-Cap Bonuses

Supply Depot Princesses

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.
- The game can only display a max of 9999 damage, but the actual damage inflicted can exceed the amount shown.
Supply Depot Princess is a soft-skinned installation for purposes of Pre-Cap Bonuses.

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 depend of the enemy. Other anti-installation bonuses are not applied to these phases.

There are exceptions:

For Torpedo Bomber:
- The torpedo stat is counted as 0 in airstrike,
- The torpedo stat is counted as [math]\displaystyle{ \bigg\lfloor \frac{TP}{2} \bigg\rfloor }[/math] in LBAS,

For Jets
:
- There are inconsistencies with the bonuses.

For the Land-Based Heavy Bombers
:
- Could have a higher modifier than other planes.

Note

For Airstrike/LBAS phase the Supply Depot Princess C Vacation Mode behave like a surface ship:
- have the stat fully counted.
- LB Attackers use the stats for damaged calculation.
- The 1.5/2.4 damage modifer for airstrike is used like other Supply Depot Princess.

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 missing bonuses from new equipment can be extrapolated from the other installation bonuses.

Equipment Performance

The following table compares the individual performance of anti-installation gears:

The calculations only look at cases using a single anti-installation gear (all synergy/overlap of nonstackable bonuses are ignored),
The firepower to reach the cap is calculated ignoring all other modifiers (engagement, formation, damage state...),
The A0 modifier is also ignored,
Post-cap modifiers are ignores (only relevant for Supply Depot Princess ),
The table works for all surface ships,
- Carriers are ignored here,
- 30 firepower needs to be added to submarines.

This table is only here to give the Big Picture regarding anti-installation equipment performances.

In any other situation, the table is invalided, notably when using more than one such equipment.

The Mod and Flat are respectively the total multiplicative bonuses and the flat bonuses given by the equipment.

Higher is better.
Note that some of them are simplified.

The "FP cap ☀/☾" columns indicate the final firepower stat (ship + equipment + fit bonuses + improvements) needed to reach the day or night cap with only the corresponding anti-installation gear equipped.

Lower is better.

Attack Animation

Some anti-installation equipment will add attack animation when targeting installation. There is no relation between the presence/absence of animation, and the presence/absence of anti-installation damage bonuses.

Notes

The animations for "artillery", "landing craft", and "airstrike", are compatible.
If multiple landing craft are equipped on the same ship, only one animation will be shown (the above table is sorted in priority order).
A variation of the animation of the Ka-Tsu tanks
is also played against Atoll Nodes when applicable.
The animation of the Armed Armed Boats
is also played against PT-Imp when equiped.
These animations will be overridden by:
- Artillery spotting,
- Night cut-in.
