Accuracy, Evasion, and Criticals are three mechanics intertwined together, representing the ability of a ship to hit another one. The formulas presented on 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 the probability of an attack hitting the target. It's the same for all attacks as well as abyssals. It stems from the difference between the Accuracy of the attack and the evasion of the target.
Hit Rate

[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} = MIN \Big[ \big( MAX \big[ ( \text{Accuracy}_\text{atk}  \text{Evasion}_\text{postcap} ) ; {\color{tomato} \text{10}} \big] \times \text{Morale}_\text{defender} \big) ; {\color{DeepSkyBlue} \text{96}} \Big] }[/math]

 With
 [math]\displaystyle{ \text{Accuracy}_\text{atk} }[/math] the calculated accuracy of the attack. Please see below for the various accuracy formulas.
 [math]\displaystyle{ \text{Evasion}_\text{postcap} }[/math] the calculated evasion of the defending ship. Please see below for the evasion formula.
 If negative, it is still applied the same way, increasing the hit rate.
 [math]\displaystyle{ \text{Morale}_\text{defender} }[/math] 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] 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 ❱❱ planes.
 Hit Rate Caps
By following this formula, the hit rate is:
 10 at minimum,
 96 at maximum.

 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.
 The effect of sparkle is reduced the closer Hit rate is to the caps.
Critical Hit Rate
Critical Hits are hits that do more damage than normal. The critical hit rate stems directly from hit rate with different proportion depending on the attack type.
Critical Rate

[math]\displaystyle{ {Crit}_\text{rate} = \lfloor \text{Mod}_\text{type} \times \sqrt{\text{Hit}_\text{cap} + \text{Acc}_\text{proficiency} } \rfloor + \text{Crit}_\text{proficiency} + 1 }[/math]

Hit Rate & Critical Roll
There is a single roll for both normal and critical hits.
For example, for a hit rate of 50% on a shelling attack, the crit rate is then 10%. The roll can be represented as followed:
Roll Example

Critical Hit 10%

Hit 40%

Miss 50%

The normal hit rate is 40% and the remaining 10% is the critical hit rate.
 Notes
 The effect of accuracy and sparkling on crit rate is limited
 Because it stems directly from hit rate, it is also affected by the caps.
 With low accuracy, a disproportionately high amount of successful hits will be "criticals".
 With proficiency bonus it's possible to have a crititical rate above the hit rate, in this case the critical rate override the hit rate.[1]
Damage Animations
When a ship takes a hit, the game will display the damage animation following in 3 possible outcomes (e.g. with 25 damage):
 miss (no damage),
 25 (normal damage)
 25 Critical hit! (critical damage).
However, the damage status displayed is mostly defined by the amount of damage dealt, and not the real damage status happening in the game.
 Due to this, displayed critical hits and misses are rarely true critical hits or misses.
The displayed damage status is as follows:
Display Behavior

Damage Dealt

Damage Displayed

Miss

Miss displayed normally

0

Always displayed as a miss

≤14

Never displayed as Critical hit!

[15;39]

Criticals displayed normally

≥40

Always displayed as Critical hit!

 Notes
 A patch exists to fix this misleading behavior and display the real damage status, see here.
Accuracy
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} = \text{Acc}_\text{equip base} + \text{Acc}_\text{equip bonus} + \text{Acc}_\bigstar }[/math] is the total accuracy provided by an equipment, with:
 [math]\displaystyle{ \text{Acc}_\text{equip base} }[/math] is the base accuracy of the equipment,
 [math]\displaystyle{ \text{Acc}_\text{equip bonus} }[/math] is the visible accuracy bonuses,
 [math]\displaystyle{ \text{Acc}_\bigstar }[/math] is the equipment's accuracy gained from Improvement,
 [math]\displaystyle{ \text{Mod}_\text{fit} }[/math] is the Hidden Fit Bonuses bonuses or penalties when applicable.
 [math]\displaystyle{ \text{Mod}_\text{formation} }[/math] is the formation modifier for the applicable attack. See Combat for more details.
 Modifiers for single fleet against combined fleet are unknown.

 Some modifiers are impossible to determine because the fleet hit the lower bound hit rate (11% hard cap).
 There are some inconsistencies between "old" and "new" enemies.
 Having a (surface ?) radar equipped reduces the smoke effect for both fleets, but only for the shelling phase.

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} = \bigg\lfloor \bigg( \Big( \text{Acc}_\text{base} + 2 \times \sqrt{\text{Level}} + 1.5 \times \sqrt{\text{Luck}} + \sum_{\text{All Equips}} \text{Acc}_\text{equip} + \text{Mod}_\text{Amagiri} \Big) \times \text{Mod}_\text{vanguard} \times \text{Mod}_\text{formation} \times \text{Mod}_\text{morale} + \text{Mod}_\text{fit} \bigg) \times \text{Mod}_\text{spotting} \times \text{Mod}_\text{AP} \times \text{Mod}_\text{smoke} \bigg\rfloor }[/math]

 Notes
 It is inadvisable to run any of the other setups beyond the most basic Gun+AP. This is because the other setups will interfere with artillery spotting and cost better attack bonuses.
 The bonus only applies against FBB, BB, BBV, CV, CVB, CA, and CAV.
 This includes Installations.
 This means that this bonus does not apply against all other types, namely CVL, CL(T), CT, DD, DE, SS(V), AV, AS, AR, LHA, or AP.

Shelling Support

This formula applies to surface shelling and carrier attacks during shelling support.
[math]\displaystyle{ \text{Accuracy}_\text{shelling support} = \bigg\lfloor \Big( 64 + 2 \times \sqrt{\text{Level}} + 1.5 \times \sqrt{\text{Luck}} + \sum_{\text{All Equips}} \text{Acc}_\text{equip base} \Big) \times \text{Mod}_\text{vanguard} \times \text{Mod}_\text{formation} \times \text{Mod}_\text{morale} \bigg\rfloor }[/math]

 [math]\displaystyle{ \text{Acc}_\text{equip base} }[/math] does not include any Visible Bonus nor Improvement.
 [math]\displaystyle{ \text{Mod}_\text{formation} }[/math] uses the same Day Shelling formation modifier as the sortieing fleet if Single vs Single combat, or 1.0 if the player fleet is Combined
 Vanguard uses Top value (0.8) only, vs DD exception also applies
 Player Single vs Enemy Combined is unconfirmed, but suspected to be 1.0 for all formations in line with Damage calculations

Torpedo Attacks

This formula only applies to opening and closing torpedo attacks during day battles.
[math]\displaystyle{ \text{Accuracy}_\text{torpedo} = \bigg\lfloor \left( \text{Acc}_\text{base} + 2 \times \sqrt{\text{Level}} + 1.5 \times \sqrt{\text{Luck}} + \sum_{\text{All Equips}} \text{Acc}_\text{equip} + \left \lfloor{\frac{\text{Attack}_\text{torp}}{5}} \right \rfloor + \text{Mod}_\text{ship} \right) \times \text{Mod}_\text{vanguard} \times \text{Mod}_\text{formation} \times \text{Mod}_\text{morale} \times \text{Mod}_\text{smoke} \bigg\rfloor }[/math]

 Notes
 Airstrike accuracy is a constant and not affected by any outside factors.

LandBased Air Squadron
This formula applies to attacks made by LandBased Air Squadrons. The accuracy is calculated independently per squadron.
LBAS

Formula for normal moral only
[math]\displaystyle{ \text{Accuracy}_\text{LBAS} = ( 90 + 7 \times \text{Acc}_\text{equip}) \times \text{Mod}_\text{Boss} + \text{Acc}_\text{Sp} }[/math]

 [math]\displaystyle{ \text{Acc}_\text{equip} }[/math] the accuracy stat of the plane,
 [math]\displaystyle{ \text{Acc}_\text{Sp} }[/math] accuracy bonus for some LBAS Special Bombers on some targets,
 Unlike other plane the B25 use special modifier against PT Imp and Installation.
 [math]\displaystyle{ \text{Mod}_\text{Boss} }[/math] being a bonus against some Boss and Imp enemy:

 Note
 There are strong evidence that abyssal skip bombers behave the same as the B25.
 Because the LB moral during waves cannot be knowed this formula is only for normal morale.

 Notes
 For / Interceptors, the and stats are respectively "AntiBomber" and "Interception" and not Accuracy and Evasion.
Evasion
Evasion has two caps depending on the calculated base evasion of the ship. Base evasion is calculated as follows:
 Notes
 Evasion term can be negative with the fuel penalty.
 The speed of the fleet is supposed to play a role in evasion. Currently, said increase is either nonexistent or too small to test,
 Submarine Equipment provide an evasion bonus to submarines against ASW attacks (around 1.2),
 Using Underway Replenishment is a way to mitigate fuel penalties,
 Because of the evasion cap, trying to increase evasion above 65 has negligible effects,
 As most ships are capable of reaching 65 , trying to increase evasion using precap means has little to no effect, this includes:
 Increasing the (e.g. with boilers, if unimproved),
 Luckmodding ,
 Choosing a weaker formation with an evasion bonus (except for Vanguard).
 Events often have "historical evasion bonuses" alongside other historical bonuses, but are not always measured due to their limitedtime nature.
Special Cases
Vanguard Formation
This mechanic's effects are still under evaluation, so values are subject to change.
When a fleet is in Vanguard Formation it gives an accuracy malus to the opposite fleet. This malus is determined by 4 factors:
 Ship position in the fleet,
 Ship type,
 Normal or event map,
 Combat phase,
It is the same for the Abyssals.
It is called [math]\displaystyle{ \text{Mod}_\text{vanguard} }[/math] in the accuracy formulas above.

Debuffs
During Events, some Debuffs have been measured to give some additional bonuses of Accuracy and Evasion .
 Please, refer to the current Event page for up to date information.
Arctic Map Bonuses
On all "arctic maps", namely all World 3 maps, as well as some Event maps, the Arctic Camouflage (+ Arctic Equipment) gives:
 3 Armor (nonstacking),
 Some Evasion .
Sources: [8] [9]
20.3cm Japanese Guns
So far, no hidden evasion bonus has been observed from equipping any gun on any ship.
 This idea comes from a misinterpretation of an ambiguous tweet by the devs [10].
AntiPT boat

Unlike most standard Abyssals, "PT boats" (PT Imp Pack & Schnellboot Imp Pack) are "very small and fast".
 All ship types suffer a severe accuracy and firepower penalty against PT boats.
 Attacking them with larger guns is not very effective, smaller guns being recommended instead.
 Support Expeditions are not affect by any of the following^{[1]}.
Attack formula against PT boats

The Attack formula against PT boats:^{[2]}^{[3]}

Accuracy formula against PT boats

The Accuracy formula against PT boats:^{[5]}^{[6]}^{[7]}^{[8]}
[math]\displaystyle{ \text{Hit Rate}_\text{vs.PT} \text{%} = \Big\lfloor ( 0.3 \times \text{Accuracy}_\text{Atk} + \sqrt{\text{Accuracy}_\text{Atk}} + 15 ) \times 1.2 \times \text{Mod}_\text{Ship} \times \Big( \prod^{All Equipment}{\text{Mod}_\text{EquipmentAcc}} \Big) \times \text{Mod}_\text{Night} \Big\rfloor  \text{EVA}_\text{PT} + 1 }[/math]

 With
 [math]\displaystyle{ \text{Acc}_\text{Atk} }[/math] the standard accuracy described here
 PT boats are "DDs" in the game, so the [math]\displaystyle{ \text{Mod}_\text{formation} }[/math] for vanguard is 1.1 during shelling, and 1.2 during the torpedo phase.
 Historical accuracy bonuses during Events are included in the Standard Accuracy Term, i.e. it is affected by the [math]\displaystyle{ \text{Mod}_\text{PT} }[/math] modifier.
 [math]\displaystyle{ \text{EVA}_\text{PT} }[/math] the PT estimated evasion described bellow,
 The main Accuracy modifiers are
 [math]\displaystyle{ \text{Mod}_\text{Amagiri} }[/math] being include in [math]\displaystyle{ \text{Acc}_\text{Atk} }[/math]:
 [math]\displaystyle{ \text{Mod}_\text{Ship} }[/math] the bonus given by ship types, described below,
 [math]\displaystyle{ \text{Mod}_\text{EquipmentAcc} }[/math] the bonuses given by equipment, described below,
 [math]\displaystyle{ \text{Mod}_\text{Night} }[/math] being 0.7 during night battle, 1 during day battle.

Amagiri Kai Ni/D has the ability to prioritize focusing on attacking PT imps with significantly increased accuracy if any are present.
 DD placed in the composition slots above and below her will gain a noticeable accuracy boost and will prioritize attacking PT boats if any are present.
 The PT boat targeting rate is 100% for all affected ships ^{[9]}.
During Events, some special bonuses may be added, with "historical" ships and equipment gaining some accuracy bonuses^{[10]}.

 Notes
 It is recommended to use antiPT setups on DDs only, such setups compromising overall combat effectiveness.
 Having a Reinforcement Expansion is important because it can save a ship slot by containing a machine gun or skilled lookouts.
 Combining equipment is recommended to see significant boosts to accuracy.
 The KaTsu Tanks
bonus does not stack with the Armed Boats ones.
 Using other setups improving accuracy is also advisable:
