Damage Formula

[math]\displaystyle{ \text{Damage} = \left [ \left [ \left [ \text{Atk}_\text{cap} \times \text{Mod}_\text{post}\right]\times \text{Crit}\right]-\text{Armour}\right]\times \text{Ammo} }[/math]

  • [math]\displaystyle{ \text{Atk}_\text{cap} }[/math] is the Cap Adjusted Attack Power
  • [math]\displaystyle{ \text{Mod}_\text{post} }[/math] is any post-cap modifiers that are applicable.
  • [math]\displaystyle{ \text{Crit} }[/math] is the critical strike modifier.
  • [math]\displaystyle{ \text{Ammo} }[/math] is the remaining ammunition modifier.
  • [math]\displaystyle{ \text{Armour} }[/math] is the armour of the target.

Where, Cap Adjusted Attack Power is Basic Attack Power that has been adjusted by applying the damage cap.

[math]\displaystyle{ \text{Atk}_\text{cap} = \text{Cap} + \sqrt{\left [ \text{Atk}_\text{basic} \times \text{Mod}_\text{pre}\right]-\text{Cap}} }[/math]

  • [math]\displaystyle{ \text{Cap} }[/math] is the damage cap relevant to the phase.
  • [math]\displaystyle{ \text{Atk}_\text{basic} }[/math] is the basic attack power of the relevant attack.
  • [math]\displaystyle{ \text{Mod}_\text{pre} }[/math] is any pre-cap modifiers that are applicable.

Important Notes

  • Pre- and post-cap multipliers are multiplicative.
  • Results are rounded down to the nearest whole number. I.e. 4.2 → 4.

Basic Attack Power Formulas

The following formulas only apply to single fleets. Please see Combined Fleet, Land-Based Air Squadron and Support Expeditions for more details.

Important Notes

  • Please see Akashi List for upgrade bonus values.
  • [math]\displaystyle{ \text{FP} }[/math] is the firepower of the ship including equipment.
  • [math]\displaystyle{ \text{TRP} }[/math] is the torpedo power of the ship including equipment or plane.
  • [math]\displaystyle{ \text{ASW} }[/math] is the anti-submarine power of the ship or equipment.
  • [math]\displaystyle{ \text{DB} }[/math] is the dive bombing power of the plane.
  • [math]\displaystyle{ \bigstar }[/math] is the upgrade bonus of the equipment.

Bombing

This applies to both jet assaults and airstrikes.

[math]\displaystyle{ \text{Bombing Power} = \text{Type} \times \left[ \left[ \left[ \text{DB}\ OR\ \text{TRP} + \bigstar \right] \times \sqrt{\text{Count}_\text{Plane}}\right] + 25\right] }[/math]

  • [math]\displaystyle{ \text{Type} }[/math] is a multiplier based on the type of the plane. See below for details.
  • [math]\displaystyle{ \text{Count}_\text{Plane} }[/math] is the number of planes performing the attack.
Type Multiplier Notes
Torpedo Bombers 0.8x or 1.5x The multiplier is chosen randomly. The chance is roughly 50%.
Dive Bombers

Seaplane Bombers
Fighter Bombers

1.0x
Jets

(During jet assault)

1.0x
Jets

(During normal bombing)

0.7071x

Important Notes

  • Bombing power is calculated independently for each equipment slot on the carrier.
  • The firepower of the carrier does not affect bombing power.
  • The power is calculated after the air combat and anti-air fire phases which means bombers getting shot down will affect the final calculation.
  • It is not affected by engagement, formation or damage states.
  • It is affected by contact.

Surface Shelling

[math]\displaystyle{ \text{Shelling Power} = \text{FP} + \bigstar + 5 }[/math]

Carrier Attacks

[math]\displaystyle{ \text{Power}_\text{carrier} = \left[ \text{FP} + \text{TRP} + \bigstar + \left[ \text{DB} \times 1.3 \right] \times 1.5 \right] + 55 }[/math]

Important Notes

  • Slot sizes and remaining plane count does not affect carrier attack power during shelling.
  • If a carrier is not equipped with any torpedo or dive bombers, she will not participate in shelling.
    • This also applies if they have lost all bombers during the aerial combat phase.
  • Carriers have the easiest time hitting the damage cap. This makes them very powerful assets for the fleet.
  • Abyssal installations equipped with a plane that has a torpedo or dive bombing stat will use the carrier formula for determining shelling damage.
