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. Landing craft specific bonuses,
  4. Flat damage bonuses,
  5. Post-cap bonuses,
  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.

  2. ↑ For example: 1 Chi-Ha  = no bonus, 2 Chi-Ha  = 1.6, 1 T89  + 1 Chi-Ha  = 2.08 (1.3x1.6)
  3. ↑ In this case the Ka-Tsu Kai count as two, 1 Ka-Tsu Kai = 1.2

Rations Bonuses

The developers have mentioned that   Rations 
 
  consumed by a girl "affect landing craft's morale"[1].

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.

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].
