Combat Stages
Stage | Notes |
---|---|
Detection | Requires planes or high detection stat. Success increases accuracy and evasion. Failure prevents participation of allied planes in the aerial combat phase. |
Aerial Combat | Requires any type of plane equipped as equipment on either side. Aerial Combat effect explained below. |
Supporting Fire | Sortie support expedition. |
Opening Torpedo Salvo | Requires torpedo cruisers, seaplane tenders or submarines equipped with midget subs (甲標的 甲 Type A Kou-hyouteki). Submarines with level 10 or higher can shoot the opening torpedo by themselves without having to equip a midget submarine. |
Shelling, 1st Round (Range Order)[1] |
Any carrier using bombers to attack during this phase must not have taken more than light damage in order to participate in the phase, with the exception of Armored Carriers (e.g. Taihou) who must not have taken more than medium damage. |
Shelling, 2nd Round (Lineup Order)[2] |
Only occurs when either side has a battleship or if the enemy contains one of the special ship classes: 鬼 (Oni/Ogress), 姫 (Hime/Princess), 戦鬼 (Senki/Battle Ogress), or 戦姫 (Senki/Battle Princess). |
Torpedo Salvo | Must not have taken more than light damage to participate. |
Night Combat | Attacks occur in lineup order from top to bottom, alternating between sides. Must not have taken more than moderate damage to participate. |
Effects of Ship Damage
Amount of damage on a ship will affect its performance.
No damage | No effect on performance. |
Minor damage (小破) | No effect on performance. +10% cut-in chance in night battle. |
Moderate damage (中破) | Attack power -30%. Unable to participate in shelling phase (CV/CVL, Taihou excluded) and torpedo salvo phase. +20% cut-in chance in night battle. |
Heavy damage (大破) | Attack power -60%. Unable to participate in shelling phase (CV/CVL) and torpedo salvo phase. Unable to participate in night battle. Unable to activate searchlight in night battle when ship HP is lower than 2. |
Aerial Combat
Aerial Combat Stages
Stage | Notes |
---|---|
Fighter Combat | Battle for air supremacy by fighter planes |
Anti-bomber Combat | Number of bombers shot down by fighters is affected by the result of the previous phase |
Fleet Anti-air Defense | Fleet defends against enemy bombers |
Bombing | See Damage Calculation for details |
Fighter Combat
[math]\displaystyle{ \text {Fighter Power} = \sum^\text{All slots} \text{Floor(} \sqrt{\text{Number fighters in slot}} \times \text {Plane anti-air bonus} \text{)} }[/math]
Fighter planes, fighter-bombers, and Zuiun participate in Fighter Combat.
The allied fleet and enemy fleet's Fighter Powers are compared to determine the result of Fighter Combat:
Fighter Power | Result | Text Display | Notes |
---|---|---|---|
FP ≥ 3*EFP | Air Supremacy | 制空権確保! Seikuuken Kakuho! |
Few allied planes shot down. |
3*EFP > FP ≥ 1.5*EFP | Air Superiority | 航空優勢! Koukuu Yuusei! |
Some planes lost. |
1.5*EFP > FP ≥ 2/3*EFP | Air Parity | No text displayed | About equal losses on both sides. |
2/3*EFP > FP ≥ 1/3*EFP | Air Incapability | 制空権喪失! Seikuuken Soushitsu! |
Many planes lost. |
FP ≤ 1/3*EFP | Air Denial | 制空権喪失! Seikuuken Soushitsu! |
- EFP: Enemy Fighter Power, FP: Fighter Power. Abbreviated to save space.
- This calculation does not take into account any anti-air weaponry equipped on ships. Carrier anti-air stat is also not considered.
- Even if allied planes secure air supremacy, planes can still be lost due to the subsequent anti-air defense stages.
- If enemy has no fighters, it'll always show "Air Supremacy" if you have airplanes on your side. Likewise, when the enemy has fighters while you don't, "Air Denial" will be shown.
Enemy Ship Fighter Power
Enemy Ship Type | Fighter Power | Enemy Ship Type | Fighter Power |
---|---|---|---|
Light Carrier Nu-Class | 8 | Armored Carrier Demon | 44 |
Light Carrier Nu-Class Elite | 24 | Armored Carrier Princess | 48 |
Light Carrier Nu-Class Flagship | 23 | Floating Fortress | 27 |
Standard Carrier Wo-Class | 10 | Southern War Demon | 41 |
Standard Carrier Wo-Class Elite | 27 | Southern War Princess | 47 |
Standard Carrier Wo-Class Flagship | 28 | Standard Carrier Wo-Class Flagship Kai | 102 |
Battleship Re-Class | 94 | ||
Battleship Re-Class Elite | 107 |
Fleet Anti-air Defense
Each enemy bomber slot is assigned at random to a defending ship. Those ships then, for each assigned enemy slot, have an approximately 50% chance to shoot down enemy planes. The number of planes shot down is given by the equations below:
[math]\displaystyle{ \text{Planes Shot Down} = \text{Floor((Ship AA } + \text{Floor(Fleet Anti-air Bonus} \times \text{Formation Modifier))} \times 0.2125\text{)} }[/math] [math]\displaystyle{ \text{Fleet Anti-air Bonus} = \text{Floor(} \sum^\text{All slots}\text{Equipment AA Bonus} \times \text{Equipment Modifier)} }[/math]
Formation Modifiers
Formation | Modifier |
---|---|
Line Ahead, Line Abreast, Echelon | 1.0 |
Double Line | 1.2 |
Diamond | 1.6 |
Equipment Modifiers
Equipment Type | Modifier |
---|---|
46cm Triple Gun Mount | 0.25 |
High-angle Cannons | 0.35 |
AA Radars | 0.40 |
Type 3 Shell | 0.60 |
All other equipment | 0.20 |
- Any equipment that gives an anti-air bonus will contribute to shooting down enemy planes.
- The forward sliding and machine gun animations seem to have no correlation with the calculations.
- These calculations only apply for the allied fleet's anti-air defense.
Damage Calculation
Main Formula
Damage = | x Pre-Cap Modifiers |
x | - | x | (between 2/3 ~ 4/3) | ||
---|---|---|---|---|---|---|---|
x | |||||||
Notes:
|
Basic Attack Power
Type | Basic Attack Power | Notes |
---|---|---|
Aerial Combat | Attack Type Modifier (see below) × [(Aircraft's divebomb or torp stat) × √(number of planes) + 25] | Number of planes is post anti-bomber combat and fleet anti-air defense |
Shelling (except Carriers) | Firepower + 5 | |
Shelling (Carrier only) | (Firepower + Torpedo) × 1.5 + Dive Bomber Stat × 2 + 55 | |
Torpedo/Preemptive Torpedo | Torpedo + 5 | |
Anti-sub warfare | (Original ASW [3] / 5, rounded down) + Equipment ASW [4] × 2 + 10 or 25 | 10 for CVL/BBV/CAV; 25 for others |
Night Battle | Firepower + Torpedo | Each may add a maximum of 150. |
Attack Type Modifier (Plane Scaling)
Type | Attack Type Modifier | Notes |
---|---|---|
Dive Bombers, Seaplane Bombers | 1 | This value is fixed, regardless the situation. |
Torpedo Fighters | 0.8 or 1.5 | About 50% chance of either modifier. |
Formation Modifier (Pre-Cap Modifier)
Formation | Formation Icon | Firepower Modifier | Anti-sub Modifier | Anti-air Modifier | Shelling Hit Rate | Torpedo Hit Rate | Flagship Protection Rate |
---|---|---|---|---|---|---|---|
Line Ahead 単縦陣 (Tanjuu-jin?) |
100% | 45% | 100% | Medium | High | Low | |
Double Line 複縦陣 (Fukujuu-jin?) |
80% | 60% | 120% | High | Medium | Medium | |
Diamond 輪形陣 (Rinkei-jin?) |
70% | 90% | 160% | Medium | Very Low | High | |
Echelon 梯形陣 (Teikei-jin?) |
60% | 75% | 100% | Medium | Low | Medium | |
Line Abreast 単横陣 (Tan'ou-jin?) |
60% | 100% | 100% | High | Very Low | Medium |
- Flagship protection is the situation where a non-flagship ship protects the flagship from being damaged by receiving the attack.
- Line Ahead is the best offensive formation for surface combat.
- Diamond formation is the best formation for aircraft carrier combat; Lowest chance of having flagship being hit according to the dev.
- Line Abreast is the best formation for anti-sub purpose(ASW).
Engagement Form Modifer (Pre-Cap Modifier)
Form | Damage Modifier | Chance (Without Saiun) |
---|---|---|
Parallel Engagement 同航戦 (Doukousen?) |
100% | 45% |
Head-on Engagement 反航戦 (Hankousen?) |
80% | 30% |
Crossing the T (Advantage) T字戦有利 (T Ji-sen Yuuri?) |
120% | 15% |
Crossing the T (Disadvantage) T字戦不利 (T Ji-sen Furi?) |
60% | 10% |
- Night battle and air combat are not affected by engagement form.
- The engagement form attack modifier affects both your fleet and the enemy fleet.
- This also applied for the Crossing the T (both Advantage or Disadvantage) modifier. It may be a bug or a design flaw.
- Crossing the T (Disadvantage) can be avoided by equipping a 彩雲 (Saiun?) (Carrier-based recon plane).
- Using Saiun effectively makes what would have been Crossing the T (Disadvantage) become Head-on Engagement.
- There is still a very small chance of getting Crossing the T (Disadvantage) with Saiun equipped.
Engagement Forms
Parallel Engagement
The course of the player's fleet and the enemy fleet are the same.
Fleet A | → | → | → | → | → | → |
Fleet B | → | → | → | → | → | → |
Head-on Engagement
The course of the player's fleet and the enemy fleet are opposite each other.
Fleet A | → | → | → | → | → | → |
Fleet B | ← | ← | ← | ← | ← | ← |
Crossing the T
The course of the player's fleet and the enemy fleet are perpendicular to each other (that's 90 degrees, which results in a T figure). A fleet is in disadvantage if it is coming from「|」direction, and is in advantage it is is coming from「―」direction.
(Historically, the point of this was for the「―」fleet to bring as many guns to bear on the enemy while limiting the firepower of the enemy that can only use guns mounted forward.)

Artillery Spotting
- When the following conditions are all met, Artillery Observed Firing (弾着観測射撃) may occur.
- Air superiority or air supremacy
- High total fleet LoS (索敵)
- Ship is of class CL, CA, CAV, BB, or BBV
- Ship is equipped with at least 1 seaplane (the slot must have at least 1 plane remaining)
- Not in heavily damaged (大破) state.
- The trigger rate is not 100% even if all requirements are met. It seems air supremacy gives a higher rate of triggering the special attack than air superiority.
- Also refered as Artillery Firing Calibration (弾着修正射撃)
Attack types:
Single Attack
- A ship will only do a single attack if
- only 1 artillery weapon equipped. (Eg. 20.3cm, 61cm torpedo)
- no main artillery weapon equipped. (Eg. 15cm, 15cm)
- Damage: 100%
Double Attack
- A ship can do a double attack if
- 2 or more main artillery weapons equipped. (Eg. 46cm, 46cm)
- Damage: 120 % x 2
Cut-in Attack
- A ship can do a cut-in attack if
- equipped with main artillery and secondary artillery. (Eg. 46cm, 15cm)
- Damage: 130 %
- Trigger chance is luck dependent
- Cut-in attack will never miss. It will atleast do scratch damage.
Mixed Attack
- A ship will have a high chance to do either double attack or cut-in attack if
- equipped with 2 main artilleries + 1 Type 91 Armor-Piercing (AP) Shell.
- Double attack Damage: 120 % x 2
- Cut-in Damage: 150 %
- Trigger chance is random.
Notes:
- Secondary artillery is required to trigger cut-in type observed fire. The secondary artillery weapon will not be shown among the cut-in equipment as shown in the second image.
- Type 91 Armor-Piercing (AP) Shell is considered an artillery weapon.
- Having only 1 Main gun + Type 91 Armor-Piercing (AP) Shell will however result in a single attack.
- Radars , Type 3 Shell, torpedoes and machine guns are not considered as artillery weapons.
Full List
Night Combat
- Night battle damage depends on both the Firepower and Torpedo stats for attack power. Consequently, DDs, CLs, CLTs and CAs have drastically increased strength at night.
- Any vessel at night must not have taken more than moderate (orange) damage before attacking in order to participate in night battle.
- Main Gun = Red guns or 10cm Twin High-angle Mount
- Secondary (Sub) Gun = Yellow guns / 12.7cm Twin High-angle Gun / 8cm Twin High-angle Gun / 10cm Twin High-angle Mount (Improved).
- Auxiliary equipment (e.g radar, sonar/depth charge, searchlight, turbine, special ammunition, pure AA equipment(green), and midget-sub) will not affect the combination.

Anti-Submarine |
Any enemy submarines will force Destroyers and Light Cruisers to target them. Cut-In and Double Attacks are ignored. In normal Night Battles, ASW damage is scratch damage only. In battles starting at night, Formation Modifiers and Engagement Form Modifiers apply. |
Cut-in Equipment Setups

Night Battle Special Attack Modifier (Pre-Cap Modifier)
Cut-in Attack
Weapon Type | Modifier |
---|---|
2 torpedoes | 2 consecutive attacks at 150% |
1 main gun, 1 torpedo | 2 consecutive attacks at 130% |
3 main guns | 200% |
2 main guns, 1 secondary gun | 175% |
Cut-in chance: (0.85 * Luck + Placement Modifier + Health Modifier + Searchlight Modifier) [%]
Modifier | Value | |
---|---|---|
Placement | Flagship | +30 |
Other | +15 | |
Health | Little or no damage | 0 |
Minor damage (小破 Syouha) | +10 | |
Moderate damage (中破 Chuuha) | +20 | |
Searchlight | Allied | +5 |
Enemy | -10 |
Double Attack
Two consecutive attacks at 120%. Almost always procs, compared to cut-ins which proc only by chance and is affected by the luck stat.
Ship's Health Modifier (Pre-Cap Modifier)
Damage | Modifier |
---|---|
Minor damage (小破 Syouha) or less | 100% |
Moderate damage (中破 Chuuha) | 70% |
Heavy damage (大破 Taiha) | 40% |
This modifier does not affect Aerial Combat.
Attack Power Cap (Applies After All Pre-Cap Modifiers)
Conditions for the attack power cap to activate: [Basic attack power x Pre-cap modifiers] exceeds 150 for day battle, 300 for night battle, and 100 for anti-sub attacks.
This is the attack power cap, and it's represented below by [math]\displaystyle{ x }[/math]:
[math]\displaystyle{ \text {Attack Power After Caps} = x + \sqrt {\text {Pre Caps Attack Power} - x} }[/math]
What we can draw from this is that during the day, firepower or torpedo stats above 146 have a high probability breaking the cap immediately and thus becoming nerfed. However, depending on the exact engagement form and fleet formation, this will not always occur.
Critical Modifier
Attack Type | Modifier |
---|---|
Normal Attack | 100% |
Critical Hit | 150% |
It should be noted that the critical message always appears when damage dealt is greater than or equal to 40, regardless of whether the 150% modifier was applied or not. On the other hand, the critical message will never appear when damage dealt is less than or equal to 14, even if the 150% modifier was applied.
Remaining Ammo Modifier
Remaining Ammunition | Modifier |
---|---|
5 to 10 bars | 100% |
4 bars | 80% |
3 bars | 60% |
2 bars | 40% |
1 bar | 20% |
0 bars | Scratch Damage |
- In general, two bars of will be used in Day Battle for all ships, regardless of whether they attack or not.
- The Remaining Ammo Modifier affects the opening Aerial Combat Phase.
- When entering night battle, the Remaining Ammo Modifier on a vessel remains same as the previous day battle. One bar of is used for all ships in Night Battle, regardless of whether they attack or not.
- Because most battles will consume 2 bars of ammunition each, try to engage the boss before the 5th battle, or else achieving victory becomes unlikely (but not impossible).
- When attempting to defeat boss nodes, avoid night battles and whirlpools on the way.
- There exist cases in which ships will consume no ammuntion in battle, but these are rare and their causes are not well documented. Most battles will consume ammuntion even if none of your ships are able to attack at all. Please report in the comments below with the exact fleet, equipment setups, map, node, and enemy pattern if you encounter battles where no ammunition is consumed.
Victory Conditions
- Perfect S
- All enemy ships sunk and no damage taken.
Not obtainable in Exercises (PvP)As of the 23 April 2014 update, Perfect S is now possible in PvP.
- S (Victory)
- All enemy ships sunk and no allied ships sunk.
- A (Victory)
- No friendly ships sunk and required number of enemy ships sunk (see below).
- B (Tactical Victory)
- Enemy flagship sunk and no allied ships sunk.
- Sinking the enemy flagship guarantees at least a B as long as no allied ships are sunk.
- Enemy flagship sunk, friendly ship sunk and number of friendly ships sunk < number of enemy ships sunk.
- Damage gauge at least 2.5 times higher enemy damage gauge.
- C (Tactical Defeat)
- Didn't clear any of the conditions for A or B, but enemy took over a certain amount of damage.
- Damage gauge higher than enemy gauge, but not reaching 2.5 times as much.
- Friendly ship sunk, damage gauge higher than enemy, but not 2.5 times as much.
- Friendly ship sunk, enemy flagship sunk and number of friendly ships sunk ≥ number of enemy ships sunk. It is possible to clear maps with boss gauges (eg. 4-4, 5-3, event maps) with a C if the enemy flagship is sunk.
- D (Defeat)
- Enemy took less than a certain amount of damage.
- Both sides taking 0 damage is also D.
- Damage gauge lower than enemy gauge.
- Friendly ship sunk, not all enemy ships sunk, and gauge lower than enemy gauge.
- E (Defeat)
- Over a certain number of friendly ships sunk. (see below)
- Friendly ship sunk while not meeting any victory conditions.
- No damage done to enemy, while taking over a certain amount (Never happens in a fleet of 1).
Notes
- The Minimum Sunk Requirement:
- 4 ships out of a fleet of 6
- 3 ships out of a fleet of 5
- 2 ships out of a fleet of 4
- 2 ships out of a fleet of 3
- 1 ship out of a fleet of 2
- Victory status affects the chance of getting drops and rare drops on the specified node.
- B victories tend to have no drops, while Perfect S has the highest chance for rare drops.
Additional Explanation/Details
- ↑ Shelling firing order is determined at the start of each shelling phase. The order alternates between allied and enemy ships, and ships unable to attack in shelling (damaged carriers, submarines, sunken ships, etc.) are skipped over to the next.
- ↑ See above.
- ↑ Refers to ASW stat without any equipment.
- ↑ Refers to the total of ASW stats that the equipment added to the ship's stats.
