Combat stages

Stage Notes
Detection

Requires planes or high detection stat.

Success increases hit rate and evasion.

Failure leaves you unable to participate in air combat phase.

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.

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 = Medium Caliber Main GunRed guns or 10cm High-angle Gun
  • Secondary (Sub) Gun = Secondary GunYellow guns / 12.7cm High-angle Gun / 8cm High-angle Gun
  • Auxiliary equipment (e.g radar, turbine, and special ammunition) will not affect the combination.


Table of night battle attack types

Cut-In 2+ Torpedo Attack
3+ Shelling
2 1+
1-2 1 Combined Attack
Double Attack 2 0 0
1 1+ 0
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.

Damage calculation

Cut-in

Weapon Type Modifier
2 torpedoes The 2 consecutive attacks - total 150%
1 main gun, 1 torpedo The 2 consecutive attacks - total 130%
3 main guns 200%
2 main guns, 1 secondary gun 175%

Double-attack

2 consecutive attack - total 120%. Always procs while cut-ins are only by chance and also affected by luck stat. (Japanese wiki confirmed that Yukikaze has a more chance of doing cut-ins than Shimakaze)

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

On attack power

Damage Modifier
Minor damage (小破) or less 100%
Moderate damage (中破) 70%
Heavy damage (大破) 40%

Modifier does not affect plane attacks (needs confirmation, because I'm not sure about google translate. source: wikiwiki)

Factors involved in damage calculation

MAIN FORMULA (work in progress):

Quote by Onnasis:

Damage =

Basic attack power multiplied by uncorrected cap x corrected critical - enemy armor x random number between 2/3 ~ 4/3
x
corrected ammo
if it isn't damaged by this formula, or becomes very little damage, it becomes scratch damage, maximum about 10% of enemy current HP (need verification)
Attack power = 

Formation

Formation Modifier
Line Ahead 100%
Double Line 80%
Diamond 70%
Echelon 60%
Line Abreast 60%

Night battle and air combat are not affected by formation choice.wikiwiki

Engagement forms

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 affect both your fleet and the enemy fleet.
  • Crossing the T (Disadvantage) can be avoided by equipping a Reconnaissance Aircraft彩雲 Saiun (Carrier-based recon plane).

Illustration of 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.)

Critical attack

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.)

Fuel and ammo (unconfirmed)

Remaining Ammunition Modifier
5 or more ammo bar 100%
4 ammo bar 80%
3 ammo bar  60%
2 ammo bar 40%
1 ammo bar 20%
0 ammo bar Scratch Damage
  • Amount of ammunition also affects the aircraft carriers damage.
  • Ships which has low fuel and/or ammo remaining has higher chance of getting heavily damaged.
  • Night battle When entering on night battle,the amount of ammunition is same after the day battle.
  • On the 5th round of the battle (nodes i guess) damage are minimized and on 6th round there will be no chance of winning, therefore the recommended boss node battle will be 4th round.
  • To prevent the the loss of firepower, avoid night battles and whirlpools on the way.

(Help: Confirmation needed if the wiki is indeed saying ammo bar. And what are game eyes? And what is Only Kasudame? Here's the link)

Magnification also affect air warfare. 

Magnification is the same for day and night battle of the battle.

User Amanies is asking for help: Everything is taken from here. Some sections weren't added because I felt that the google translation wasn't accurate (or I didn't understand it at all).
