Combat Stages
| Stage | Notes |
|---|---|
| Detection | Requires planes or high detection stat.
Success increases hit rate and evasion. |
| Air Combat | |
| Supporting Fire | Map 5, requires sortie support expedition. |
| Opening Torpedo Salvo | Requires midget subs or submarines over level 10 |
| Shelling, 1st Round (Range Order) | Any carrier using bombers to attack during this phase must not have taken more than light damage in order to participate in the phase. |
| Shelling, 2nd Round (Lineup Order) | Only occurs when one or both sides has a battleship, or the enemy contains one of the special ship classes: 鬼, 姫, 戦鬼, or 戦姫. |
| 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.
| Minor damage (小破) or less | No effect on performance |
| Moderate damage (中破) | Attack power, accuracy, and evasion are slightly decreased |
| Heavy damage (大破) | Attack power, accuracy, and evasion are significantly decreased |

Formation Modifier (Pre-Cap Modifier)
| Formation | Formation Icon | Modifier | Modifier when attacking subs |
|---|---|---|---|
| Line Ahead (単縦陣) |  |
100% | 45% |
| Double Line (複縦陣) |  |
80% | 60% |
| Diamond (輪形陣) |  |

| Echelon (梯形陣) |  |
60% | 75% |
| Line Abreast (単横陣) |  |
60% | 100% |
Night battle and air combat are not affected by formation choice.
Engagement Form Modifer (Pre-Cap Modifier)
| Form | Modifier |
|---|---|
| Parallel Engagement (同航戦) | 100% |
| Head-on Engagement (反航戦) | 80% |
| Crossing the T (Advantage) (T字戦有利) | 120% |
| Crossing the T (Disadvantage) (T字戦不利) | 60% |
- 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).
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.)
| → | → | → | → | → | → | ← | ← | ← | ← | ← | ← | ||
Night Combat
- Night battle damage depends on either the Firepower or Torpedo (or both!) stats for attack power, depending on the specific attack type. Consequently, DDs, CLs, CLTs and CAs have drastically increase 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 High-angle Gun - Secondary (Sub) Gun =
Yellow guns / 12.7cm High-angle Gun / 8cm High-angle Gun - Auxiliary equipment (e.g radar, turbine, special ammunition, pure AA equipment(green), and mini-sub) will not affect the combination.
Night Battle Attack Types
| Type | Main | Secondary | Torpedo | Notes |
|---|---|---|---|---|
| Cut-In | 2+ | Torpedo Attack | ||

| 0 | 2+ | 0-1 | Secondary Gun Double-Attack, Torpedo doesn't fire | |
| Single Attack | Results from failing to meet equipment requirements, or other attacks random chance at failing. Fires with gun or torpedo in highest equipment slot. | |||
| Anti-Submarine | Any enemy submarines will force Destroyers and Light Cruisers to target them. Cut-In and Double Attacks are ignored. | |||

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% |
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. (Japanese wikis confirm that Yukikaze has a greater chance of doing cut-ins than Shimakaze)
Cut-in chance can be approximated with: (Ship Luck + 20) [%]
Ship's Health Modifier (Pre-Cap Modifier)
| Damage | Modifier |
|---|---|
| Minor damage (小破) or less | 100% |
| Moderate damage (中破) | 70% |
| Heavy damage (大破) | 40% |
Modifier does not affect aerial attacks.
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 150 have the possibility of breaking the cap immediately and thus becoming nerfed. Best to use that extra red gun on Yamato or torp on Kitakami Kai 2 on something else.
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. (If, on the other hand, the critical message appeared when the damage dealt was less than 40, then it was a critical hit.)
Remaining Ammo Modifier
| Remaining Ammunition | Modifier |
|---|---|
5 or more  bar
|
100% |
| 4 bar
|
80% - 90% |
| 3 bar
|
60% - 70% |
| 2 bar
|
40% - 50% |
| 1 bar
|
20% - 30% |
| 0 bar
|
Scratch Damage (1% - 5%) |
- One bar of will be used each time the ship enters shelling mode. The bar will be decreased for all ship in the fleet, regardless if they shoot or not.
- For the Torpedo Salvo session, there will be no ammunition decrease. This also applied for the opening Torpedo Salvo.
- This is not applied to Submarines, which their torpedo attack will also decrease their ammunition by 1 bar for each torpedo.
- When entering night battle, the amount of ammunition on a vessel is same as after the day battle. However, on night battle, the one that have their ammunition reduced only those who fires.
- The default ammo usage for each battle is 2 bars. In case your ship consume less than 2 bars in a battle, they'll get 2 bars decrease after the battle ends.
- For the Torpedo Salvo session, there will be no ammunition decrease. This also applied for the opening Torpedo Salvo.
- Amount of ammunition also affects aircraft carrier damage.
- Ships which are low on fuel and/or ammo remaining have higher chance of getting heavily damaged.
- Due to the nature that most of battles will consume 2 bars of ammunition each, on the 5th battle (nodes) in the same sortie, you'll run out of ammunition, which will ensure your loss on the next battle.
- Make sure on every map boss battle landed on 3rd or 4th battle, since if they are on the 5th battle, your winning chance are greatly reduced.
- To prevent the the loss of firepower while trying to reach the boss, avoid night battles and whirlpools on the way.
- While early map's whirpool decreases your resource directly, later maps will decrease either
or bar of your sorted fleet, which may cause disadvantages for you especially when you're low of them. - However, if you're only going for the experience and/or rare drops, do the night battle to gain the S victory, since S victory will give you more EXP and higher chance for rare drops.
- While early map's whirpool decreases your resource directly, later maps will decrease either
Victory Conditions
- Perfect S
- No damage taken, all enemy ships sunk.
- S (Victory)
- All enemy ships sunk.
- A (Victory)
- No friendly ships sunk and required number of enemy ships sunk. (see below)
- B (Tactical Victory)
- Enemy flagship sunk.
- If your flagship not sunk and enemy doesn't met the minimum sunk requirement (see below), you'll got B regardless how bad are you damaged if enemy's flagship sunk.
- No damage taken, and enemy took over a certain amount of damage.
- Damage gauge at least twice enemy damage gauge.
- Friendly ship sunk, specified number of enemy ships sunk (see below), and damage gauge twice enemy gauge.
- Friendly ship sunk, enemy flagship sunk, and damage gauge twice enemy 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 twice as much.
- Friendly ship sunk, damage gauge higher than enemy, but not twice as much.
- 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.
Notes
- The Minimum Sunk Requirement is around 60% of your fleet, thus:
- 4 ships out of fleet of 6
- 3 ships out of fleet of 5
- 3 ships out of fleet of 4
- 2 ships out of fleet of 3
- 1 ship out of fleet of 2
- Heavy damage on the 1st ship out of fleet of 1
- 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 drop, however, these chance modifier are not too significant.
Additional Explanation/Details
- ↑ Refers to ASW stat without any equipment.
- ↑ Refers to the total of ASW stats that the equipment added to the ship's stats.

※ 以上の計算式は「制空権確保」時のものであるため、それ以外の状況では異なる可能性がある。 航空戦でのダメージは各スロットの機体性能と搭載数から個々に計算されており、空母の火力値は攻撃力に影響しない。 搭載数はリアルタイムに反映されており、雷撃・爆撃の前に艦載機が撃ち落とされた場合は、そのぶん攻撃力が減少する。 航空戦ではキャップ前補正（陣形補正、交戦形態補正、損傷補正）を受けない。 防御側の対空はダメージに直接は影響しない。ただし敵艦載機を撃ち落とすことによって搭載数を減少させたり、回避率に影響している可能性はある。
装甲の堅い敵に艦攻が有効なのは、倍率150%の攻撃があるためである。ただしこの倍率は80%の場合もあり、攻撃力は安定しない。
航空戦では互いの艦上戦闘機による制空権の判定が行われ、（被）撃墜数などに大きく影響する。 制空権の影響を大きく受けるのが艦攻で、艦爆は比較的受ける影響が少ないと言われている。
Apparently this is calculation's accuracy can only be justified when you managed to get air superiority, aka "制空権確保".
As we all know, damage during "Air Combat" phase is only affected by plane capacity and the type of planes you have. The "Firepower" stats doesn't affect anything during this phase.
Seems like AA also does not affect the damage during Air Combat directly, just that it is possible that the more planes you shoot down, the higher chance you get to evade the bombings.
Then there's the part whereby it informs us that it's effective against ships with high armor due to the possibility of having a 150% scaling during the bombing.
And as we all know, air superiority is also determined by how many planes were shot down and the side without air superiority will be doing considerably less damage on bombing. (Wording doesn't include torpedo, so I'm not sure whether they're including both bombing and torpedo as one category)
