Combat/Anti-Installation

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.
Hard Skin	Takes more damage from Anti-Installation equipment like Landing Craft, Special Amphibious Tank and Anti-ground Artillery

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).
• 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-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.
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

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

• 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-Ground Equipment" is recommended to deal the most dame against installations:

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 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 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
	1	2	3
Allied Day Shelling Damage
Allied balloons [10]	1.02	1.04	1.06
Allied LBAS Damage
Allied balloons [11]	1.02	1.04	1.06
Enemy balloons [12]	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 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 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
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 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.

Post-Cap Bonus

Supply Depot Princess

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 hard-cap of 9999.
• 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".

	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 is roughly 50%.

There are exceptions:

• For Torpedo Bomber:
  • The torpedo stat is counted as 0 in airstrike,
  • The behavior is unclear for LBAS (the damage are overestimated).

• For Jets
  :
  • There are inconsistencies with the bonuses.

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

Equipment Setups

Below are recommended equipment setups for anti-installation purposes. The equipment order is illustrative and does not reasonably matter.

As a general rule:

• Regarding :
  • If a ship's base firepower is low, it can be viable to use Anti-Ground Rockets to provide a large flat damage increase to supplement the ship's anti-installation damage.
  • Depending on whether one or more Anti-Ground Artilleries are to be equipped on a ship, it is recommended to use a WG42 for singular purposes, or Shipborne Model Type 4 20cm Anti-ground Rocket Launchers (or CD) if multiple are needed.
  • ASW Mortar
    are inferior substitutes to regular Anti-Ground Artilleries when lacking those.
• Regarding and :
  • These provide a high damage multiplier against Installations. Some specialized variants also provide an additional flat damage increase that is multiplicative with certain modifiers.
  • As Landing Craft and Special Amphibious Tanks have separate multipliers, it is recommended to use them in tandem to maximize the effect.

Nuke Setup describes any setups using anti-installation equipment from multiple categories to multiplicatively amplify damage dealt to Installations.

• Such a setup has a strong anti-installation power against all installations but is hampered by the daytime damage cap.
• Nuke Setups are recommended to be used when dealing with Supply Depot Princess in particular, utilizing the high post-cap side of the bonuses to deal with her generally high HP pool.
• The setup's damage can be further improved by using multiple copies of those types of equipment where applicable.
  • For example, equipping multiple Special Amphibious Tanks or Landing Craft with unique bonuses instead of anti-ground rockets provides better damage output for the ship, however, it is advised to only do so if you have enough available for the other ships in your fleet that require them.

All "surface" anti-installation setups can be further enhanced by using them in Special Attacks, especially Nelson's Touch.

Equipment Setup	Notes
BB/FBB/BBV
	The basic battleship setup. Because Battleships are not far away from the damage cap compared to other ship types, they do not benefit much from the high pre-cap multipliers that anti-installation equipment provides. The standard artillery spotting setup will allow them to utilize spotting attacks and AP Shell's post-cap bonuses against the installation, as well as be effective against all other targets in the enemy fleet.
	This is an option when facing soft-skinned installations. Taking an AA shell will slightly improve their damage versus installations, but will also limit the battleship's effectiveness against all other targets by reducing their artillery spotting attack types.
	Yamato-class Kai Ni & Ise-class Kai Ni only. "Best of both worlds" for 5-slot battleships.
	Nagato-class Kai Ni & Yamato Kai Ni Juu only. The landing craft/special amphibious tank will make their Special Attacks deal significantly more damage to installation enemies. Keeping the seaplane allows to still perform artillery spotting to maintain enough effectiveness against other targets.
+ or +	Nuke Setup , Yamato Kai Ni Juu only. A proper nuke setup keeping the Double Attack and artillery spotting, that uses Yamato's ability to carry Secondary Guns in her RE, also taking advantage of her Special Attack. An AP Shell may be used to replace the anti-ground rockets to improve performance against other targets, while improving the damage multiplier of Yamato's Special Attacks and Artillery Spotting types.
CA/CAV
	The standard anti-installation setup for heavy cruisers. It allows artillery spotting and deals decent damage against installations.
or +	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. For Mogami-class Cruisers with a Reinforcement Expansion, an option to equip 8cm High Angle Guns in the expansion slot in order to retain a weaker variant of artillery spotting is a viable alternative.
+	Nuke Setup , Mogami Kai Ni Toku only. The last setup uses Mogami's ability to carry 8cm High-angle Guns in her RE, making this a true nuke setup while keeping the Double Attack.
CL
	Nuke Setup
	A 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
	Mini-Nuke Setup Substitute nuke setups to use ONLY when lacking Landing Craft or Special Amphibious Tanks.
	Setups that keep the Double Attack while maintaining decent anti-installation power, allowing reasonable effectiveness against installation and other targets at night.
	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 when having 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, it still ensures that carriers will do significant damage to installations and other targets.
	Gambier Bay Mk.II & Unyou Kai/Ni only. The closest setup to a proper "CV nuke".
AV
	Nuke Setup 4-slot AVs can also either take a 2nd anti-ground rocket, a midget sub, or a seaplane fighter in their last slot.
	Double Nuke Setup are recommended instead of to avoid "Hidden Accuracy Penalties". This setup is for 4 slots AV to utilize the "Nuke" with a "Night DA".
LHA
