Combat Stages

For most combat engagements, the battle will begin in day combat and follow the following set of stages. Several stages will not occur unless certain conditions are met. For Event maps, a Combined Fleet mechanic has been implemented which follows a modified combat order.

Stage Notes
Formation Selection With 4 or more ships in a fleet, a fleet formation must be selected before combat. The selected formation affects ship damage, hit rate, and defense.
Detection Requires planes or high detection stat (usually from RADAR).
Success increases accuracy and evasion.
Failure prevents participation of allied planes in the aerial combat phase.
Aerial Combat Participants: CVLs, CVs, BBVs, CAVs, AVs, SSVs

Requires any type of offensive plane (torpedo bombers and dive bombers for CVLs and CVs, and seaplane bombers for BBVs, CAVs, AVs, and SSVs) equipped as equipment on either side.
If a side achieves Air Superiority or Supremacy in this stage, that side can use Artillery Spotting.

Opening Stages

Expedition Supporting Fire

Supporting Fire from Sortie Support Expeditions. This has an aspect of randomness and may not trigger.

Opening Torpedo Salvo

Participants: [[::Category:Submarines|SS]] over level 10, ships equipped with TorpedoesType A Ko-hyoteki (CLTs, AVs, [[::Category:Submarines|SS]]) and enemy Battleship Re-Class Elite. All participants fire their torpedoes simultaneously.

Engagement Form

The orientation of the allied and enemy fleets is displayed. This affects both fleets equally.

Day Combat

Shelling, 1st Round (Range Order)

Participants: All ships except SS. Firing order alternates between allied and enemy sides starting with allied. For each side, ships with higher range have priority. The firing order is composed of only ships that are able to take part and is set at the start of each shelling phase. Any ships sunk or incapacitated before their turn results in a lost turn for the side it is on.

Shelling, 2nd Round (Lineup Order)

Participants: All ships except SS. Firing order alternates between sides, prioritizing ships at the top of the list.

Only occurs when either side has a BB, BBV, or the enemy has one of the special ship classes (鬼 Oni/Ogress, 姫 Hime/Princess) which acts like a BB/BBV: Destroyer Princess (駆逐棲姫) does not, while Battleship Princess (戦艦棲姫) does. The distinction between Bosses that do and those that do not trigger this phase is not always clear from their names.

Closing Torpedo Salvo

Participants: DDs, CLs, CLTs, CAs, CAVs, SS, Bismarck drei, Battleship Re-Class

Like the opening torpedo salvo, all participants attack simultaneously.

Night Combat Participants: All ships except CVLs and CVs.

Enemy Standard Carrier Wo-Class and Light Carrier Nu-Class of flagship level or higher can attack at night.

Must not be critically damaged to participate.

The first slot allied ship attacks, then the first slot enemy ship attacks, and so on. Similar to shelling phase, if a ship is sunk or critically damaged, the game will skip its turn.

For certain nodes and events, combat begins in the Night Combat stage, then proceeds to Day combat, if certain conditions are met.

Formation Selection

With 4 or more ships in a fleet, a fleet formation must be selected before combat. The selected formation affects ship damage and hit rate.

Formation Modifier

Formation Formation Icon Surface Damage Modifier Anti-sub Modifier Anti-air Modifier Shelling Hit Rate Torpedo Hit Rate Flagship Protection Rate
Line Ahead
単縦陣 (Tanjuu-jin?)
Formation 1: Line Ahead
100% 45% 100% Medium High Low
Double Line
複縦陣 (Fukujuu-jin?)
Formation 2: Double Line
80% 60% 120% High Medium Medium
Diamond
輪形陣 (Rinkei-jin?)
Formation 3: Diamond
70% 90% 160% Medium Very Low High
Echelon
梯形陣 (Teikei-jin?)
Formation 4: Echelon
60% 75% 100% Medium Low Medium
Line Abreast
単横陣 (Tan'ou-jin?)
Formation 5: Line Abreast
60% 100% 100% High Very Low Medium
  • The above data reflect effects in Day Battle.
  • The surface damage modifier applies to both shelling and torpedo attacks, but does not affect Aerial Combat or Anti-Submarine attacks.
  • Diamond Formation is only selectable as a formation with 5+ ships.
  • Flagship protection is the situation where a non-flagship ship protects the flagship from being damaged by receiving the attack instead.
  • Line Ahead has the highest offensive power for surface combat. It is the default choice for encounters after the 3rd battle node to preserve firepower because of the remaining ammo penalty.
  • Double Line is generally a good formation for heavy BB/CV fleets. There is a significant accuracy increase that benefits the typically lower accuracy carriers, while BB often still have enough firepower.
  • Line Abreast is the best formation for anti-sub purposes.
  • Echelon has not been tested extensively, but it is hypothesized to be a defensive formation for submarines.

Detection

  • Fleet LOS affects Detection rate.
  • Success increases fleet accuracy and evasion.
  • Failure prevents participation of allied planes in the aerial combat phase.

Aerial Combat

Aerial Combat Stages

Stage Notes
Fighter Combat Battle for air supremacy. Determines if Artillery Spotting and/or Contact are possible.
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][1]

Fighter planes, fighter-bombers (bombers with +AA stat), and seaplane bombers 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 % Shot Down Contact
FP > 3*EFP Air Supremacy 制空権確保!
Seikuuken Kakuho!
0~90% Allied only
3*EFP > FP > 1.5*EFP Air Superiority 航空優勢!
Koukuu Yuusei!
0~80% Both sides
1.5*EFP > FP > 2/3*EFP Air Parity No text displayed 0~60% Both sides
2/3*EFP > FP > 1/3*EFP Air Incapability No text displayed 0~40% Both sides
FP > 1/3*EFP Air Denial 制空権喪失!
Seikuuken Soushitsu!
0~10% Enemy only
  • 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.
  • The percentage of planes shot down applies for both sides' respective outcomes, and is calculated per slot.
    • For example, securing Air Superiority means allied planes shoot down up to 80% of enemy planes, and the enemy under Air Incapability will shoot down up to 40%.
    • As this is applied per slot, 80% of one enemy bomber group can be shot down while a second has 0% shot down.
  • Contact can be triggered by having at least 1 carrier scout plane, seaplane scout, and/or torpedo bomber equipped. It increases damage during the bombing phase depending on the accuracy bonus of the squad triggering Contact.
  • Even if allied planes secure air supremacy, planes can still be lost (up to 10%), and the subsequent anti-air defense stage can eliminate more bombers.
  • If enemy fleet launches no fighters, while the allied fleet launches any planes, the result defaults to Air Supremacy. If both sides launch no planes, then the rest of the battle is treated the same as if Air Parity was achieved.

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 Battleship Re-Class 94
Standard Carrier Wo-Class Flagship 2 76 Battleship Re-Class Elite 107
Standard Carrier Wo-Class Kai Flagship 102 Northern Princess World 3-5 76

Fleet Anti-air Defense

This may have changed with the Fall Event Update. The addition of Anti-air Directors and the Anti-air Cut-In may not be the only changes to AA Defense. The effects and mechanics are currently in need of investigation.

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{Shot Down} = \text{Floor((Ship AA } + \text{Floor(Fleet Anti-air} \times \text{Formation Modifier))} \times 0.2125\text{)} }[/math] [math]\displaystyle{ \text{Fleet Anti-air} = \text{Floor(} \sum^\text{All slots}\text{Equipment AA Bonus} \times \text{Equipment Modifier)} }[/math]

The "Fleet Anti-Air" bonus is the sum of every equipment slot of every ship in the fleet (including the defending ship).

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 Mounts 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 bombers.
  • The ship chosen to defend against bombers is not necessarily the ship targeted by that slot.
  • The ship selected to defend is not necessarily the target of the bomber. Any allied ship, including submarines, may be chosen to defend against bombers.
  • 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; enemy fleets seem to use a different formula.

Opening Stages

The Opening Stages of combat proceed in order with the Supporting Expedition effect, the Opening Torpedo salvo, then the display of the engagement form

  • In World 5 and Event Maps, the Sortie fleet can receive a salvo of Support fire from fleets deployed on Support Expeditions. The type of supporting fire depends on the composition of the expedition fleet.
  • The Opening Torpedo Salvo is fired by Submarines over level 10, ships with the TorpedoesType A Ko-hyoteki (CLTs, AVs, [[::Category:Submarines|SS]]) equipped, and the Enemy Battleship Re-Class.
    • Torpedoes are fired from all ships simultaneously, and accuracy is affected by the selected Formation type.
    • Ships must not be moderately or heavily damaged to participate
  • The Opening stages finish with the display of the Engagement form, the orientation of the two fleets.

Engagement Form Modifier

Form Damage Modifier Chance Chance with Saiun
Parallel Engagement
同航戦 (Doukousen?)
100% 45% 45%
Head-on Engagement
反航戦 (Hankousen?)
80% 30% 40%
Crossing the T (Advantage)
T字戦有利 (T Ji-sen Yuuri?)
120% 15% 15%
Crossing the T (Disadvantage)
T字戦不利 (T Ji-sen Furi?)
60% 10% 0%
  • Please note that all engagement forms affect both sides equally, including crossing the T (Advantage or Disadvantage).
  • Night battle and aerial combat are not affected by engagement forms. Torpedo salvos are affected by engagement forms.
  • Equipping a Reconnaissance AircraftSaiun effectively makes what would have been Crossing the T (Disadvantage) become Head-on Engagement.
  • It is speculated that the Engagement form also impacts accuracy.

Day Combat

  • Day Combat consists of up to 3 phases: 1st Shelling, 2nd Shelling, Closing Torpedo
  • During the first shelling stage, the order of fire is determined by the ship's maximum range.
    • Ships are arranged in order from Very Long -> Long -> Medium -> Short range.
    • The shelling order alternates from allied ships to enemy ships if able. If two ships on the same side have the same range, the ship that attacks first from between them is chosen randomly.
  • The second shelling phase moves from the top to the bottom of the combat line.
  • CVLs and CVs must be in good or lightly damaged condition in order to participate in shelling phases, with the exception of Armored Aircraft Carriers (e.g. Taihou) who can still attack while moderately damaged.
  • The Closing Torpedo phase operates the same as the Opening Torpedo phase above, with the exception that no midget sub is required to fire.

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.
  • Certain Combinations of weapon equipment (Main Guns, Secondary Guns, Torpedoes) will cause Cut-In or Double Attacks at night, greatly increasing accuracy and/or firepower
  • If night combat nodes are anticipated, it can be very helpful to utilize specialized night battle equipment such as Star Shells and Searchlight. Type 98 Recon Seaplane (Night Scout) is also an option.
  • Formation bonuses and penalties apply in night battles, but Engagement Forms do not. (Exception: In Nodes that begin with a Night Battle, an Engagement Form is rolled invisibly, the multiplier for which is applied to Anti-Submarine damage only.)

  • If [Basic attack power x Pre-cap modifiers] exceeds a certain cap, it will be modified -- see below
  • This formula is under constant review and updated accordingly if there any inconsistencies or mistakes happens.

Basic Attack Power

Type Basic Attack Power Notes
Aerial Combat Plane Scaling × [(Aircraft's Dive Bomb or Torpedo stat) × √(Number of Planes) + 25] Number of planes is post anti-bomber combat and fleet anti-air defense
Shelling (Carriers) (Firepower + Torpedo) × 1.5 + Dive Bomb × 2 + 55
Shelling (Others) Firepower + 5
Torpedo Torpedo + 5
Anti-sub warfare Bonus * ((Ship ASW / 5) + 2 * Equipment ASW + Type) Type: 25 if Sonar/Depth Charge (DD, CL), 10 if aircraft (CVL, CAV, BBV)

Bonus: 1.15 if both Sonar and Depth Charge are equipped, 1.0 otherwise.

Night Battle Firepower + Torpedo
  • According to wikiwiki, multiple SONAR/Depth charges do not boost the ASW Bonus (i.e. 2 of each still makes the bonus 1.15)

Pre-Cap Modifiers

Formation Modifier

The Base Attack Power is multiplied by the damage modifier from the selected Formation.

Engagement Modifier

The Attack power is then multiplied by the damage modifier from the Engagement Form.

Ship's Health 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.

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.
An example of a cut-in

Night Special Attack Modifier (Cut-In and Double Attack)

Certain Equipment setups have a chance to cause special attacks at night, causing 20-100% more damage. Detailed set ups and damage modifiers can be found in the Combat Equipment Setups below. In Night Combat, the damage modifiers from the special attack type are applied before the cap.

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]

Daytime Attack Cap often makes it important to utilize Artillery Spotting when possible to increase damage. Night Combat can be very dangerous and/or rewarding due to having a very high cap and the inclusion of torpedo to firepower for attack power calculation.

Post-Cap Modifiers

Artillery Spotting

Certain Equipment setups have a chance to cause special daytime Artillery Spotting attacks, dealing 10-50%. Detailed set ups and damage modifiers can be found in the Combat Equipment Setups below. For Artillery Spotting, the damage modifiers from the special attack type are applied after the cap.

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.

Contact

  • Contact takes place during the Aerial Combat phase. It increases bombing damage for all allied bombers.
  • When successful, a image of the squadron performing contact is shown in the opposing fleet's formation indicator, with the text "触接中".
  • Trigger conditions:
    • More air control than Air Denial
    • At least one carrier scout plane, seaplane scout, or torpedo bomber equipped.
    • It's thought that each carrier scout plane, seaplane scout, and/or torpedo bomber slot equipped is given a chance to trigger contact. Once successful, the bonus applied is chosen at random with weighting from all eligible equipped planes.
  • Different types of planes have different trigger rates. They are roughly estimated as (if only one is equipped):
Type Contact Rate
Torpedo Bomber ~2%
Seaplane Scout ~20%
Carrier Scout ~50%

Contact Damage Modifier

  • The damage increase depends on the +accuracy bonus Accuracy of the squadron performing contact.
Accuracy
Bonus
Damage
Modifier
+0 112%
+1 112%
+2 117%
+3 120%

Notes

  • Reconnaissance AircraftType 2 Recon Aircraft is useful in the case that the bombing damage bonus is desired while not removing the chance for T-disadvantage, due to its high trigger rate.
  • With contact, the maximum attack power of bombing (before defense, critical and ammo) is around 180. With some luck, it's possible to sink even Ru-class Flagships (Armor = 99) in one strike without a critical.

Remaining Ammo Modifier

Remaining Ammunition Modifier
5 to 10 Ammunition bars 100%
4 Ammunition bars 80%
3 Ammunition bars 60%
2 Ammunition bars 40%
1 Ammunition bar 20%
0 Ammunition bars Scratch Damage
  • In general, two bars of Ammunition 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 Ammunition 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.
    • While early maps' whirlpools decrease your resources directly, later maps will decrease either Fuel or Ammunition bars of your sorted fleet, which can be disadvantageous in long sorties.
  • Submarine-only nodes on limited-time event maps do not consume ammo in Day or Night Battle.


Combat Equipment Setups

Artillery spotting allows your ships with seaplanes to double attack and cut-in during day battle.

  • When the following conditions are all met for a ship, artillery spotting may occur.
    • Proper equipment (see below)
    • Air superiority or greater achieved in aerial combat phase
      • Thus, if aerial combat is not triggered, artillery spotting cannot occur.
    • Not in heavily damaged (大破) state
    • Ship is carrying at least 1 seaplane Seaplane (i.e. slots are not all at 0 remaining).

Notes:

  • Luck Luck and sparkling do not affect the trigger chance of artillery spotting.
  • Artillery spotting cut-in attacks cannot miss, but they may inflict scratch damage instead.
  • Type 3 Shell Anti-Aircraft Shell, torpedoes Torpedoes and machine guns Anti-Aircraft Gun, and SONAR SONAR and other misc. equipment like turbines do not count toward triggering artillery spotting.
  • Tables of main guns and secondary guns

Day Battle Special Attacks (Artillery Spotting)

Single Attack

  • A ship will only do a single attack if
    • only 1 main gun is equipped (e.g.Medium Caliber Main GunTorpedoesRADAR).
    • no main guns are equipped (e.g. Secondary GunSecondary Gun).
    • a double attack/cut-in was not triggered by chance.
  • Damage: 100%

Double Attack

  • A ship can do a double attack during the daytime if
    • 2 or more main guns equipped (e.g. Large Caliber Main GunLarge Caliber Main Gun).
  • Damage: 120 % x 2
  • Trigger chance: ~50%

Cut-in Attack

File:KanColle-140425-17422431.png
Cut-in Type Observed Fire using 1Main 1Sec & Type 91 AP shell
  • A ship can do a cut-in attack if
    1. equipped with 1 main gun and 1-2 secondary guns (without AP shell/Radar) (e.g. Large Caliber Main GunSecondary Gun).
      • Damage: 110 %
    2. equipped with 1 main gun, 1 secondary gun and 1 radar (e.g. Large Caliber Main GunSecondary GunRADAR).
      • Damage: 120%
    3. equipped with 1 main gun, 1 secondary gun and 1 Red Shell (Armor Piercing)[2]
      • Damage: 130 %
  • Cut-in attacks receive an accuracy bonus.
  • Trigger chance: ~50%

Mixed Attack

Cut-in Type Mixed Attack Observed Fire with 2 Main & Type 91 AP Shell.
  • A ship will have a chance to do either double attack or cut-in attack if
    1. equipped with 2 main guns + 1 secondary gun (e.g. Large Caliber Main GunLarge Caliber Main GunSecondary Gun).
      • Cut-in damage: 130 %
      • Double attack damage: 120 % x 2
    2. equipped with 2 main guns + 1 Red Shell (Armor Piercing)[3]
      • Cut-in damage: 150 %
      • Double attack damage: 120 % x 2
  • Trigger chance: Equally distributed, ~30% each (double attack and cut-in attack), with the remainder going towards single attack.


Night Battle Special Attacks

Single Attack

  • A ship will only do a single attack if
    • only 1 main gun is equipped (e.g.Medium Caliber Main GunTorpedoesRADAR).
    • no main guns are equipped (e.g. Secondary GunSecondary Gun).
    • a Double or Cut-in attack was not triggered by chance.
  • Damage: 100%

Double Attack

  • A ship will do a double attack if equipped with:
    • 2 Main Guns, no Secondary Guns, and no Torpedoes (e.g. Medium Caliber Main GunMedium Caliber Main GunRADAR).
    • 1 Main Gun, 1+ Secondary Guns, and no Torpedoes (e.g. Medium Caliber Main GunSecondary GunSecondary Gun).
    • No Main Guns and 2 or more Secondary Guns, 1 or 0 Torpedoes (e.g. Secondary GunSecondary GunTorpedoes).
  • Damage: 120% x 2
  • Trigger Chance: High (??%)

Cut-In Attack

  • Several types of Cut-In attacks exist
    • Cut-In (Torpedo): Two or more torpedoes equipped (e.g. Medium Caliber Main GunTorpedoesTorpedoes).
      • Damage 150% x 2 (simultaneous)
    • Cut-In (Mixed): 1-2 Main guns, 1 torpedo equipped (e.g. Medium Caliber Main GunMedium Caliber Main GunTorpedoes).
      • Damage: 130% x 2 (consecutive)

      • Damage: 200%
    • Cut-In (Shelling): 2 Main guns, 1+ Secondary guns (e.g. Medium Caliber Main GunMedium Caliber Main GunSecondary GunSecondary Gun).
      • Damage: 175%
  • Trigger Chance: Luck Based. See Cut-In Chance below

Note: If two attacks (simultaneous or consecutive) are made, the total damage is displayed together but the Damage Cap (and enemy Armor) is applied separately to each attack.

Anti-Sub Warfare

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 apply.

Night Double Attack Chance

Has a high and relatively consistent activation chance. Activation rate decreases with damage states, but is not dependent on luck. This typically results in more consistent and higher average damage than cut-in setup for ships with normal luck values.

Common Setups

  • Common ship equipment setups and their purpose
  • Destroyers
    • As destroyers do not have the ability to field seaplanes, have low firepower but high torpedo stats, and few equipment slots, their use in fleets is generally to meet composition requirements. Their common setups focus on Anti-Sub Warfare, Night Torpedo, or Fleet Anti-Air Support
    • A Mixture of SONAR and Depth Charges (SONARDepth Charges) make your destroyers effective, accurate sub killers when enemy fleets contain Submarines.
    • On destroyers with high luck (Ayanami, Shigure, Yukikaze), 2 or 3 pieces of Torpedo Equipment (TorpedoesTorpedoesTorpedoes) will often trigger a potent Torpedo Cut-In attack in Night Combat.
    • When facing maps with many enemy fleets with carriers, destroyers can provide a considerable amount of fleet AA support using 10cm High-Angle Guns High-Angle Gunor dedicated Anti-Air gunsAnti-Aircraft Gun to reduce incoming bomber damage to your bigger ships.
  • Light Cruisers
    • Light Cruisers gain access to the Medium size Main guns to buff their firepower as well as seaplanes (with a few exceptions with regards to seaplanes, those being CLTs, Isuzu Kai Ni, Yuubari and both of the Tenryuu class), making Artillery Spotting setups feasible and effective against moderately armored enemy vessels.
    • For light cruisers facing enemy fleets, a setup with 2 Main guns and a Seaplane (Medium Caliber Main GunMedium Caliber Main GunSeaplane) offers a potent double attack in both daytime Artillery Spotting and Night combat.
    • The special class of the Torpedo Cruisers deserves some mention here: their specialty lies in their torpedoes and should almost always be equipped to maximize their torpedo damage or accuracy with a TorpedoesType A Ko-hyoteki (to enable opening torpedo strikes) and other Torpedo Equipment.
  • Heavy Cruisers
    • Heavy Cruisers see the introduction of 4 slot setups after remodeling and all of them feature the ability to launch seaplanes for artillery spotting. While they are still limited to the Medium main guns, their higher firepower and armor can make them solid combatants when Battleships are unavailable or overkill.
    • The go-to setup for most situations will be the 2 Main, 1 Secondary gun, 1 seaplane setup (Medium Caliber Main GunMedium Caliber Main GunSecondary GunSeaplane) which provides a mixed attack pattern of double and cut-in attacks with a high activation chance during Artillery Spotting as well as a shelling cut-in during night combat.
    • When LOS requirements are important, the Secondary Gun can be replaced with a RADAR to get a Day and Night Double Attack setup (Medium Caliber Main GunMedium Caliber Main GunRADARSeaplane).
    • Certain Event bosses take additional damage when a ship is equipped with Type 3 Shells. As heavy cruisers have access to these, a Heavy Cruiser may find swapping the secondary gun for a Type 3 Shell (Medium Caliber Main GunMedium Caliber Main GunAnti-Aircraft ShellSeaplane) to be an effective pocket battleship against such targets (see Airfield Princess).
    • In the case of a battle occurring with Night Combat first, one option is to replace the seaplane with and additional gun, lose the day combat special attacks to double down on the shelling cut-in damage at night (Medium Caliber Main GunMedium Caliber Main GunMedium Caliber Main GunSecondary Gun)
  • Battleships
    • Battleships feature a selection of Heavy Main Guns and massive resulting firepower in addition to the potent Armor Piercing shells which can cause brutal critical hits. Setups for battleships are similar to those of heavy cruisers, with one notable addition.
    • The Armor Piercing Shells that battleships have access to allows for the highly effective 2 Main gun, AP Shell, Seaplane setup (Large Caliber Main GunLarge Caliber Main GunArmor-Piercing ShellSeaplane) which has a more effective Artillery Spotting Cut-In, while providing better stats than secondary guns.
    • Note: Official tweets state that overuse of cannons larger than what a BB is meant for will make it "overweight" and incur a "minor" accuracy penalty. (IE: Too many 46cm or even 41cm cannons on Fast Battleships such as Kongou-class and Bismark.) The effects haven't been noticeable enough to make any concrete statements.
  • Carriers
    • Planes. Enough Fighters to achieve Air Superiority or Supremacy, fill out with Torpedo Bombers on larger slots for preemptive bombing damage and/or Dive Bombers on smaller slots for shelling damage.
    • Torpedo Bombers and Dive Bombers are roughly equivalent to each other. While Torpedo Bombers have the advantage in the preemptive aerial bombing, their damage are dependent on number of surviving planes, making air superiority very important for them. In cases where Air Superiority is not feasible, using more Dive Bombers may prove more effective.

Full Setup List

  • What follows is an extensive list of possible equipment setups related to Artillery Spotting and Night Battle attacks.
  • Yellow: Cut-In or Double Attack Possible
    • While equipping ships, keep in mind the impacts of the equipment stats, the lower probability of Cut-In attacks, as well as the ship's own stats. Weigh the advantages of a setup in Day Combat vs Night Combat and consider carefully which setups are appropriate for the sorties and exercises you are facing!

Victory Conditions

Perfect S
  • All enemy ships sunk and no damage taken.
S (Victory)
  • All enemy ships sunk and no allied ships sunk.
A (Victory)
  • Required number of enemy ships sunk (see below) and no allied ships sunk.
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.
    • If your fleet consist only 1 ship and it is reaching Heavy Damage without meeting any winning requirements, it will instantly judged as D as well.
  • 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 rank and above are necessary to obtain drops.
    • A rank and above appear to be necessary for obtaining rare drops.
    • S rank appears to have a higher chance of obtaining rare drops than A rank.
      • There appears to be a correlation between enemy fleet formations and drops, but this information is still under verification and beyond player control.[4]

Additional Explanation/Details

  1. Example on how to calculate a ship's fighter power using the formula. Akagi Kai's fighter power (with Reppus in slot 1 and 2, Reppu Kai in slot 3, M62 in slot 4) = Floor[ √(Slot 1) x Reppu's AA] + Floor[ √(Slot 2) x Reppu's AA] + Floor[ √(Slot 3) x ReppuKai's AA] + Floor[ √(Slot 4) x M62's AA] = Floor[ √(20) x 10] + Floor[ √(20) x 10] + Floor[ √(32) x 12] + Floor[ √(10) x 4] = 44 + 44 + 67 + 11 = 166
  2. Red Shells are currently: Type 91 Armor-Piercing (AP) Shell or Type 1 Armor-Piercing (AP) Shell. The Anti-Air Type 3 Shell does NOT work.
