Combat is a major component of the game in Kantai Collection. Combat is accessed through the [[Sortie]] menu by selecting a map to send a fleet. Multiple mechanics weave together to create an intricate combat dynamic. For more detailed explanations on the various combat mechanics, please see the individual pages below. [[Exercises]] also consist of one surface combat.

On each node, combat will consist of several "Combat Phases". The number of combat phases depends on the node type, with each node type using a different set of combat phases and order.

==Formation Selection==
 +
If the fleet currently deployed has 4 or more ships, the player will be prompted to pick a fleet formation before every battle. Fleets with 3 or less ships will not have a fleet formation prompt and will default to '''Line Ahead'''.
 +
* Sunk ships and ships [[Evacuation|evacuated]] with a {{EquipmentLink|Fleet Command Facility|Striking Force Fleet Command Facility|Elite Torpedo Squadron Command Facility|text=Command Facility|link=Evacuation}} are not counted.
 +
* Diamond Formation requires 5 or more ships present in the fleet to be selected.
 +
* Enemy fleets do not have these restrictions. Enemy fleets in Diamond formation with fewer than 4 ships lack formation graphics on the battle screen.
 +
Combined Fleets have special [[Combined Formation|formations]] that differ from the standard single fleet ones.

−
''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)</ref>

(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.)

NOTE: These are only a few examples.  See the above table.

'''Flagship Protection''' is when a non-flagship protects the flagship from being targeted by receiving the attack instead. When activated, a "curved shield" animation plays in front of the flagship's banner.

 +
===Vanguard Formation===
 +
Vanguard is only available during [[Event]]s, and is usable on '''any map''' during this time.
 +
* The modifiers on Vanguard Formation refer respectively to the '''"upper half"''' and '''"bottom half"''' of the fleet.
 +
** For a fleet with 6 or 7 ships, the top row applies to ships 1 to 3, and the bottom row applies to the remaining ships.
 +
** For a fleet with 4 or 5 ships, the top row applies to ships 1 and 2 and the bottom row applies to the remaining ships.
 +
* '''Damage and accuracy of [[Support Fleet]]s are affected by the top row multipliers, meaning the 50% damage modifier is applied.'''
  
−
====Double-attack Equipment Setups====
+
Vanguard gives an accuracy penalty to the opposite fleet. See ''[[Accuracy, Evasion and Criticals#Vanguard Formation|here]]'' for more details.

 +
The '''bottom half''' ships have an increased chance to be targeted.
 +
* The targeting is determined as follows:
 +
**1. Target a ship from the fleet.
 +
**2. If the selected ship is an upper half ship, target a ship from the fleet again.<ref>https://twitter.com/Xe_UCH/status/974571652229955584</ref>
 +
* Target rate based on the above procedure (without other factor):
 +
* Bug: When the Vanguard is selected with a [[Combined Fleet]] (on night nodes only) the "'''number of ships'''" column is determined by using the  in the '''main''' fleet number of ships<ref>https://discord.com/channels/118339803660943369/178613137430282240/1286997214580703335</ref>.
 +
**E.g. With 4 ship main fleet and a 6 ship escort, the "4 ships" column is to be counted.

===Choosing a Formation===
 +
[[File:Formation_Selection_Screen.png|thumb|right|Formation Selection Screen]]
 +
When selecting a formation, its modifiers will be applied to the entirety of the next battle node whenever applicable. Picking another formation will discard any previous formation bonuses and penalties and use the new modifiers instead. Each formation has a general use-case archetype based on its modifiers.
  
−
===Attack Power Cap (Applies After All Pre-Cap Modifiers)===
+
* '''Line Ahead''': All-out surface combat formation.
−
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.<br />This is the attack power cap, and it's represented below by <math>x</math>:
+
* '''Double Line''': All-around, high accuracy formation.
 +
* '''Diamond''': Anti-Air formation.
 +
* '''Echelon''': Mixed surface-ASW combat formation.
 +
* '''Line Abreast''': ASW formation.
 +
* '''Vanguard''': Defensive/evasive & anti DD/[[PT Imp]] formation (event only).
 +
* [[Combined Fleet]] has other formations.
  
−
<math>\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.
+
Other mechanics available on this menu:
 +
* This UI can be hidden by clicking once or twice on the flagship, to see the map.
 +
** The [[Fleet Preview|Enemy composition preview]] once hidden.
 +
* The smoke screen button if a {{Smoke}} [[Smoke Generator]] is equiped in the fleet.

**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.
 
−
*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.
 
−
**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.

;Notes
 +
* B-ranks are the minimum victory requirements for:
 +
** Obtaining [[drop]]s.
 +
** Clearing a map without a boss gauge.
 +
* Drops (both rate and pool) scale based on rank obtained. Some drops might be exclusive to higher ranks.
 +
* Perfect S (Total Victory) ranks count as a regular S-Rank.
 +
** Perfect S is fulfilled if all ships' final HPs on battle ended is greater than or equal to initial HPs on battle started.
 +
** So it is possible to obtain a perfect S if the only damaged ship has used a '''[[Repair Goddess]]''' in battle, and her final HP is still greater than or equal to her initial. 
  
−
===Notes===
+
==MVP==
−
*The Minimum Sunk Requirement is around 60% of your fleet, thus:
+
At the end of combat, one girl is picked as the MVP. She gains exp and morale bonuses. For more details, please see ''[[Experience and Rank]]'' and ''[[Morale and Fatigue]]''.
−
** 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.
 
  
 +
The way MVP is determined is:
 +
* The girl who deals the highest total damage (sum of all attacks during the combat) is awarded MVP. This damage is not weighted.
 +
* If multiple girls are tied for damage, the MVP goes to the topmost girl in the fleet order.
 +
* If the ship achieving the most damage would be sunk in the battle, MVP is rewarded to the next highest damage dealer instead.
 +
** As such, if no damage is dealt to the enemy, the flagship automatically receives MVP.
 +
* Battles ending in an E-Rank have no MVP.
 +
* In a Combined Fleet, each fleet has its own independent MVP.

Combat is a major component of the game in Kantai Collection. Combat is accessed through the Sortie menu by selecting a map to send a fleet. Multiple mechanics weave together to create an intricate combat dynamic. For more detailed explanations on the various combat mechanics, please see the individual pages below. Exercises also consist of one surface combat.

Combat Phases

On each node, combat will consist of several "Combat Phases". The number of combat phases depends on the node type, with each node type using a different set of combat phases and order.

  • See Nodes for more details.
  • Using a Combined Fleet will also affect the phases, especially during the shelling.

The combat phases are made out of:

  6. Closing Torpedo Salvo
  1. Friendly Fleet (event only)
  2. Support Expedition*
  3. Night Contact and Spotting
  4. Night Shelling Phase

Formation Selection

If the fleet currently deployed has 4 or more ships, the player will be prompted to pick a fleet formation before every battle. Fleets with 3 or less ships will not have a fleet formation prompt and will default to Line Ahead.

  • Sunk ships and ships evacuated with a Command FacilityFleet Command Facility
    Striking Force Fleet Command Facility
    Elite Torpedo Squadron Command Facility     are not counted.
  • Diamond Formation requires 5 or more ships present in the fleet to be selected.
  • Enemy fleets do not have these restrictions. Enemy fleets in Diamond formation with fewer than 4 ships lack formation graphics on the battle screen.

Combined Fleets have special formations that differ from the standard single fleet ones.

  • Exact values were datamined from KanColle Kai for the Vita. Testing on the browser version has corroborated these results.
    • Values for Vanguard and the new Echelon are vague as they weren't introduced for KanColle Kai.

Flagship Protection

Flagship Protection is when a non-flagship protects the flagship from being targeted by receiving the attack instead. When activated, a "curved shield" animation plays in front of the flagship's banner.

Vanguard Formation

Vanguard is only available during Events, and is usable on any map during this time.

  • The modifiers on Vanguard Formation refer respectively to the "upper half" and "bottom half" of the fleet.
    • For a fleet with 6 or 7 ships, the top row applies to ships 1 to 3, and the bottom row applies to the remaining ships.
    • For a fleet with 4 or 5 ships, the top row applies to ships 1 and 2 and the bottom row applies to the remaining ships.
  • Damage and accuracy of Support Fleets are affected by the top row multipliers, meaning the 50% damage modifier is applied.

Vanguard gives an accuracy penalty to the opposite fleet. See here for more details.

The bottom half ships have an increased chance to be targeted.

  • The targeting is determined as follows:
    • 1. Target a ship from the fleet.
    • 2. If the selected ship is an upper half ship, target a ship from the fleet again.[1]
  • Target rate based on the above procedure (without other factor):
  • Bug: When the Vanguard is selected with a Combined Fleet (on night nodes only) the "number of ships" column is determined by using the in the main fleet number of ships[2].
    • E.g. With 4 ship main fleet and a 6 ship escort, the "4 ships" column is to be counted.
Target Rate
Fleet position Number of ships
4 5 6 7
1 12,50% 8,00% 8,33% 6,13%
2 12,50% 8,00% 8,33% 6,13%

Choosing a Formation

Formation Selection Screen

When selecting a formation, its modifiers will be applied to the entirety of the next battle node whenever applicable. Picking another formation will discard any previous formation bonuses and penalties and use the new modifiers instead. Each formation has a general use-case archetype based on its modifiers.

  • Line Ahead: All-out surface combat formation.
  • Double Line: All-around, high accuracy formation.
  • Diamond: Anti-Air formation.
  • Echelon: Mixed surface-ASW combat formation.
  • Line Abreast: ASW formation.
  • Vanguard: Defensive/evasive & anti DD/PT Imp formation (event only).
  • Combined Fleet has other formations.

Victory Conditions

Once the battle ended, a damage gauge is displayed on the post-combat screen for each allied and enemy fleet, using the following calculation:


Gamage Gauge Formula
[math]\displaystyle{ \text{Damage}_\text{%} = \frac{\text{Fleet}_\text{HP lost} }{\text{Fleet}_\text{HP} } }[/math]
With
  • [math]\displaystyle{ \text{Fleet}_\text{HP lost} }[/math] the total amount of HP lost by ships in the fleet,
  • [math]\displaystyle{ \text{Fleet}_\text{HP} }[/math] the total amount of HP of the fleet at the start of the battle.
    • It may be lower than the maximum HP possible,
Notes

The following conditions must be met to attain each rank:

Victory State Rank Common name Conditions
Victory Total Victory: S
(完全勝利S) 		Perfect S
  • Sink all enemy ships, while taking no damage in return.
  • In Short Battle Nodes, take 0 damage.
Victory: S
(勝利S) 		S rank
Victory: A
(勝利A) 		A rank
Tactical Victory: B
(戦術的勝利B) 		B rank
  • Sink the enemy flagship and have fewer ships sunk than the enemy.
  • If the enemy flagship survives and the Damage % gauge is at least 2.5x less than the enemy's.
  • In Short Battle Nodes, take between 10% and 20% damage.
  • If any of the ships sink, this is the maximum rank obtainable.
Defeat Tactical Defeat: C
(戦術的敗北C) 		C Rank
  • The enemy flagship survives and the Damage % gauge is between 0.5x and 2.5x less than the enemy's.
    • Also applies when sinking any ship during the battle.
  • If the enemy flagship is sunk but the enemy has fewer sunken ships, as well as having the Damage % gauge between 0.5x and 2.5x less than the enemy's.
  • In Short Battle Nodes, take between 50% and 20% damage.
Defeat: D
(敗北D) 		D rank
  • If the enemy flagship survives and the Damage % gauge is less than 0.5x of the enemy's.
  • If the Damage % dealt is 0.05% (essentially 0).
  • If both fleets deal no damage to each other.
    • This applies to submarine vs submarine battles and air battle nodes.
  • Ships are sunk but not enough to meet the conditions for E.
  • In Short Battle Nodes, take heavy damage.
Defeat: E
(敗北E) 		E rank
  • The enemy flagship survives and the number of sunk ships in the fleet meets the minimum kill requirements.
    • Not meeting the requirements for a D Rank.
Notes
  • B-ranks are the minimum victory requirements for:
    • Obtaining drops.
    • Clearing a map without a boss gauge.
  • Drops (both rate and pool) scale based on rank obtained. Some drops might be exclusive to higher ranks.
  • Perfect S (Total Victory) ranks count as a regular S-Rank.
    • Perfect S is fulfilled if all ships' final HPs on battle ended is greater than or equal to initial HPs on battle started.
    • So it is possible to obtain a perfect S if the only damaged ship has used a Repair Goddess in battle, and her final HP is still greater than or equal to her initial.

MVP

At the end of combat, one girl is picked as the MVP. She gains exp and morale bonuses. For more details, please see Experience and Rank and Morale and Fatigue.

The way MVP is determined is:

  • The girl who deals the highest total damage (sum of all attacks during the combat) is awarded MVP. This damage is not weighted.
  • If multiple girls are tied for damage, the MVP goes to the topmost girl in the fleet order.
  • If the ship achieving the most damage would be sunk in the battle, MVP is rewarded to the next highest damage dealer instead.
    • As such, if no damage is dealt to the enemy, the flagship automatically receives MVP.
  • Battles ending in an E-Rank have no MVP.
  • In a Combined Fleet, each fleet has its own independent MVP.
