→Landing Craft Specific Bonuses
==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<ref>https://docs.google.com/document/d/1mXGyJ3yeNWeOmuGZQrXkcuGSuSEQYqmKhPelHMkzkGI/edit</ref>:
# [[#Ship Type Bonuses|Ship type bonuses]],
# [[#General Multiplicative Bonuses|General multiplicative bonuses]],
# [[#Landing Craft Specific Bonuses|Landing craft specific bonuses]],
# [[#Flat Damage Bonuses|Flat damage bonuses]],
# [[#Post-Cap Bonuses|Post-cap bonuses]],
# [[#Airstrike And Land-Base Bonus|Airstrike and land-base]] special cases,
# [[#Installation-Like Warships|"Installation-like warships"]] special cases.
*The bonuses' exact order is still under investigation and may be subject to changes.

;Notes
;Notes
* Any excess attack power above this cap is square-rooted. ''See the [[#Damage Formula|damage formula]] for how it is applied.
* The Improvement Bonus takes the average for all Landing Craft equipped on the ship.
* It is still worth aiming to go above the attack power cap because some pre-cap modifiers can severely reduce the attack power.
* The Improvement Bonus takes the average for all Special Amphibious Tanks equipped on the ship.

;Notes:
*A {{LandingCraft}} [[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 [[Land-Based Air Squadron#Attack Power|LBAS]] and [[Damage_Calculations#Airstrike|airstrike]] page. The multiplier is chosen randomly between two values. The chance is roughly 50%.
There are exceptions:
*For {{BluePlane}} [[Torpedo Bomber]]:
** The {{torpedo}} torpedo stat is counted as 0 in airstrike,
** The behavior is unclear for LBAS (the damage are overestimated).
*For {{JetFighterBomber2}}{{JetFighterBomber1}} {{EquipmentLink|Kikka Kai|Jet Keiun Kai|text=Jets|link=Jets}}:
** There are inconsistencies with the bonuses.
===Critical Strikes===
*For the {{Large Land-based Aircraft}} {{Equipment/Link|Shinzan|Shinzan Kai|text=Land-Based Heavy Bombers|link_category=Land-Based Heavy Bombers}}:
** Could have a higher modifier than other planes.
