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 display cap of 9999.
- If the damage displayed is 9999, the actual damage can be higher.
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 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.

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].
