This page is to provide an in-depth look into the hit rate mechanics in-game for single/combined fleets and land-based air squadrons. The formulas presented in this page are still subject to change as more testing is done.
- Please note that all formulas between [math]\displaystyle{ \lfloor \ \rfloor }[/math] are rounded down.
Hit Rate
The hit rate is used by all attacks.
[math]\displaystyle{ \text{Hit %} = \bigl\lfloor \text{Hit}_\text{cap} \bigr\rfloor + \text{Acc}_\text{proficiency} +1 }[/math]
Where, the Capped Hit Rate [math]\displaystyle{ \left( \text{Hit}_\text{cap} \right) }[/math] is:
[math]\displaystyle{ \text{Hit}_\text{cap} = \text{cap}_\text{max}\left( \text{cap}_\text{min} \left(\text{Accuracy}_\text{atk} - \text{Evasion}_\text{def}\right) \times \text{Morale}_\text{defender} \right) }[/math]
- [math]\displaystyle{ \text{Accuracy}_\text{atk} }[/math] is the calculated accuracy of the attack. Please see below for the various accuracy formulas.
- [math]\displaystyle{ \text{Evasion}_\text{def} }[/math] is the calculated evasion of the defending ship. Please see below for the various evasion formulas.
- [math]\displaystyle{ \text{Morale}_\text{defender} }[/math] is the morale state modifier of the defending ship. Morale is referring to the value of attacking timing, not the value before entering battle. Please see Morale and Fatigue for more details.
- Sparkled is 0.7,
- Normal is 1.0,
- Orange is 1.2,
- Red is 1.4.
- [math]\displaystyle{ \text{Acc}_\text{proficiency} }[/math] is the average plane proficiency accuracy bonus. Please see Plane Proficiency for more details.
- The average is calculated only from dive bombers, torpedo bombers, seaplane bombers and large flying boats.
- The value is 12 for ❱❱ ranked planes.
Hit Rate Caps
There is a minimum and maximum hit rate in the game.
- The minimum of [math]\displaystyle{ \text{cap}_\text{min}\left(x\right) }[/math] is 10.
- The maximum of [math]\displaystyle{ \text{cap}_\text{max}\left(x\right) }[/math] is 96.
Notes:
- Hit rate has an effective minimum of 11% and a maximum of 97%.
- Plane proficiency is the only factor that allows a ship to go beyond 100% hit rate.
Critical Hit Rate
The following are the various formulas for determining critical hits for attacks.
- Shelling/ASW (including carriers): [math]\displaystyle{ \lfloor 1.3 \times \sqrt{\text{Hit}_\text{cap}} \rfloor + \text{Crit}_\text{proficiency} + 1 }[/math]
- Torpedo: [math]\displaystyle{ \lfloor 1.5 \times \sqrt{\text{Hit}_\text{cap}} \rfloor + 1 }[/math]
- Airstrike: [math]\displaystyle{ \lfloor 0.2 \times \sqrt{\text{Hit}_\text{cap}} \rfloor + \text{Crit}_\text{proficiency} + 1 }[/math]
- Night Battle (including carriers): [math]\displaystyle{ \lfloor \left(1.5 + \text{Const}_\text{contact} \right) \sqrt{\text{Hit}_\text{cap}} \rfloor + 1 }[/math]
- Shelling Support: [math]\displaystyle{ \lfloor 1.0 \times \sqrt{\text{Hit}_\text{cap}} \rfloor + 1 }[/math]
- Airstrike Support: [math]\displaystyle{ \lfloor 0.2 \times \sqrt{\text{Hit}_\text{cap}} \rfloor + 1 }[/math]
- [math]\displaystyle{ \text{Crit}_\text{proficiency} }[/math] is the plane proficiency critical bonus. Please see Plane Proficiency for more details.
- [math]\displaystyle{ \text{Const}_\text{contact} }[/math] is the night contact constant from Night Recons
. It is 0.07 if night contact is triggered, 0 otherwise.
Accuracy Formulas
Below are the common variables used in all accuracy formulas:
- [math]\displaystyle{ \text{Level} }[/math] is the level of the attacking ship.
- [math]\displaystyle{ \text{Luck} }[/math] is the luck of the attacking ship.
- [math]\displaystyle{ \text{Acc}_\text{equip} }[/math] is the total accuracy provided by the equipment calculated as [math]\displaystyle{ \text{Acc}_\text{equip base} + \text{Mod}_\text{Impr} \times \sqrt{\bigstar} }[/math]
- [math]\displaystyle{ \text{Acc}_\text{equip base} }[/math] is the base accuracy displayed on the equipment.
- [math]\displaystyle{ \text{Mod}_\text{Impr} }[/math] is the equipment's Improvement modifier for the applicable attack.
- [math]\displaystyle{ \bigstar }[/math] is the equipment's improvement level.
- [math]\displaystyle{ \text{Mod}_\text{formation} }[/math] is the formation modifier for the applicable attack. Please see Combat for more details.
- [math]\displaystyle{ \text{Mod}_\text{morale} }[/math] is the morale modifier of the attacking ship. Morale is referring to the value of attacking timing, not the value before entering battle. Please see Morale and Fatigue for more details.
[math]\displaystyle{ \text{Mod}_\text{morale} }[/math] | |
---|---|
Sparkled | 1.2 |
Normal | 1.0 |
Orange | 0.8 |
Red | 0.5 |
Notes:
- Because of the number of modifiers to accuracy in-game, it is trivial to increase accuracy. Therefore it is more important to prioritize firepower.
Daytime Shelling
This formula applies to both surface shelling and carrier attacks during daytime combat. It does not apply to carrier airstrikes.
[math]\displaystyle{ \text{Accuracy}_\text{shelling} = \biggl\lfloor \left( \left( \text{Acc}_\text{base} + 2\sqrt{\text{Level}} + 1.5\sqrt{\text{Luck}} + \sum_{\text{All Equips}} \text{Acc}_\text{equip} \right) \times \text{Mod}_\text{formation} \times \text{Mod}_\text{morale} + \text{Mod}_\text{fit} \right) \times \text{Mod}_\text{spotting} \times \text{Mod}_\text{AP} \biggr\rfloor }[/math]
- [math]\displaystyle{ \text{Acc}_\text{base} }[/math] is the base accuracy value of the attack.

Aerial Combat
This formula applies to the airstrikes performed during the aerial combat phase and support. Although ASW support functions like an airstrike for damage, it does not use this formula.
[math]\displaystyle{ \text{Accuracy}_\text{airstrike} = 95 }[/math]
Important Notes
- Airstrike accuracy is a constant and not affected by any outside factors.
Anti-Submarine Warfare
This formula applies to all ASW attacks in the combat phase and support.

Notes:
- Equipping more sonars is the best way to boost ASW accuracy.
- Large sonars are not counted for this bonus.
Night Battles
This formula applies to all night battle attacks.
[math]\displaystyle{ \text{Accuracy}_\text{NB} = \bigl( \text{Mod}_\text{contact} \left( 69 + \text{Mod}_\text{star shell} \right) + 2\sqrt{\text{Level}} + 1.5\sqrt{\text{Luck}} + \sum_{\text{All Equips}} \text{Acc}_\text{equip} \bigr) \times \text{Mod}_\text{formation} \times \text{Mod}_\text{morale} \times \text{Mod}_\text{special} + \text{Mod}_\text{searchlight} + \text{Mod}_\text{fit} }[/math]

- Red morale: 0.8
- [math]\displaystyle{ \text{Mod}_\text{proficiency} }[/math] is the plane proficiency accuracy bonus. Please see Plane Proficiency for more details.
- The value is 12 for ❱❱ ranked planes.
Evasion Formulas
Evasion has several caps depending on the calculated base evasion of the ship. Base evasion is calculated as follows:
[math]\displaystyle{ \text{Evasion}_\text{base} = \bigl\lfloor \left( \text{Evasion}_\text{ship} + \sqrt{2\text{Luck}} \right) \times \text{Mod}_\text{formation} \bigr\rfloor }[/math]
- [math]\displaystyle{ \text{Evasion}_\text{ship} }[/math] is the evasion of the ship including any visible equipment bonuses.
- [math]\displaystyle{ \text{Mod}_\text{formation} }[/math] is the formation modifier. It varies based on the attack being received. Please see Combat for more details.
- Currently modifiers for Vanguard are unknown.
The various capped evasion formulas to calculate the final evasion rate is as follows:
- [math]\displaystyle{ \text{Evasion}_\text{base} \lt 40: \text{Evasion}_\text{cap} = \text{Evasion}_\text{base} }[/math]
- [math]\displaystyle{ 40 \lt \text{Evasion}_\text{base} \lt 65: \text{Evasion}_\text{cap} = \lfloor 40 + 3\sqrt{\text{Evasion}_\text{base} - 40} \rfloor }[/math]
- [math]\displaystyle{ \text{Evasion}_\text{base} \gt 65: \text{Evasion}_\text{cap} = \lfloor55 + 2\sqrt{\text{Evasion}_\text{base} - 65}\rfloor }[/math]
Capped evasion is then modified by post-cap modifiers:
[math]\displaystyle{ \text{Evasion %} = \biggl\lfloor \text{Mod}_\text{searchlight} \times \left( \text{Evasion}_\text{cap} + \text{Mod}_\text{sonar} + \text{Mod}_\text{CA} + \text{Mod}_\text{vanguard} - \text{Mod}_\text{fuel} \right) \biggr\rfloor }[/math]
- [math]\displaystyle{ \text{Mod}_\text{searchlight} }[/math] is the searchlight evasion penalty. It is 0.2 for any ship equipped with a searchlight (even if not triggered) and 1.0 otherwise.
- [math]\displaystyle{ \text{Mod}_\text{sonar} }[/math] is the sonar improvement modifier that only applies to opening and closing torpedo attacks. It is 0 otherwise.
- [math]\displaystyle{ \text{Mod}_\text{sonar} = \sum_{\text{All Sonars}} 1.5\sqrt{\bigstar} }[/math]
- [math]\displaystyle{ \text{Mod}_\text{CA} }[/math] is the heavy/aviation cruiser night battle evasion bonus. It is 5 for heavy/aviation cruisers and 0 otherwise.
- [math]\displaystyle{ \text{Mod}_\text{vanguard} }[/math] is the Vanguard evasion bonus. This is different from the formation modifier that gets taken into account for base evasion. Bonuses are:
- For ships at the top (slots 1-2 or 1-3): Non-destroyers get a 5% bonus. Destroyers get a 20% bonus.
- For the rest of the ships at the bottom (slots 3-5 or 4-7): Non-destroyers get a 20% bonus. Destroyers get a 40% bonus.
- [math]\displaystyle{ \text{Mod}_\text{fuel} }[/math] is the remaining fuel penalty.
- [math]\displaystyle{ \text{Mod}_\text{fuel} = 75 - \text{Fuel} }[/math]
- If fuel is above 75%, the penalty is 0.
- The penalty is an integer and not a percentage.
Battle #[1] | Remaining Fuel | Penalty |
---|---|---|
2nd Battle | 80% | 0 |
3rd Battle | 60% | 15 |
4th Battle | 40% | 35 |
5th Battle | 20% | 55 |
6th+ Battle | 0% | 75 |
- ↑ This only takes into account normal day battles. Special nodes have different resource consumption.
Notes:
- The speed of the fleet is supposed to play a role in evasion. Currently, said increase is either nonexistent or too small to test.
- Using AO equipped with Underway Replenishment is a way to medigate fuel penalties.
Special Cases
