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.

==Effects of Ship Damage==

=Combat Phases=
Amount of damage on a ship will affect its performance.
+
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.

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:

*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%.
 
*[[Combat#Contact (Post-Cap Modifier)|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 performing Contact.
 
*Even if allied planes secure air supremacy, planes can still be lost due to the subsequent anti-air defense stage.
 
*If enemy has no fighters but you have, the result defaults to Air Supremacy. Likewise, if you have no fighters but enemy has, the result defaults to Air Denial. However, if both party have no fighter, then it'll be set to Air Parity.

===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:
 
 
<center>
 
<math>\text{Planes Shot Down} = \text{Floor((Ship AA } + \text{Floor(Fleet Anti-air Bonus} \times \text{Formation Modifier))} \times 0.2125\text{)}</math> <math>\text{Fleet Anti-air Bonus} = \text{Floor(} \sum^\text{All slots}\text{Equipment AA Bonus} \times \text{Equipment Modifier)}</math>
 
</center>
 
"Fleet Anti-Air Bonus" is the sum of every equipment slot of every ship in the fleet (including the defending ship).

*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.
 
*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 use different math.
 
*What this means is that a ship's AA stat represents their ability to shoot bombers targeting them, where their equipment's AA represents their ability to shoot down bombers attacking other friendly ships.

'''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===
 
[[File:3.png|thumb|An example of a cut-in]]
 
*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.
 
*[[List of Main Guns by stats|List of Main Guns]]
 
*[[List of Secondary Guns by stats|List of Secondary Guns]]
 
*Auxiliary equipment (e.g radar, sonar/depth charge, searchlight, turbine, special ammunition, pure AA equipment(green), and midget-sub) will not affect the combination.
 
*If night combat nodes are anticipated, it can be very helpful to utilize specialized night battle equipment such as [[Star Shell]]s 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.)

=====Double Attack Equipment Setups=====

==Formation Selection==
NOTE: These are only a few examples.  See the above table.
+
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.

===Vanguard Formation===
|-
+
Vanguard is only available during [[Event]]s, and is usable on '''any map''' during this time.

+
** 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.
| Minor damage (小破 Syouha) or less

This modifier does not affect Aerial Combat.
 
  
 +
Vanguard gives an accuracy penalty to the opposite fleet. See ''[[Accuracy, Evasion and Criticals#Vanguard Formation|here]]'' for more details.
  
===Attack Power Cap (Applies After All Pre-Cap Modifiers)===
+
The '''bottom half''' ships have an increased chance to be targeted.
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>:
+
* 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.
  
<math>\text {Attack Power After Caps} = x + \sqrt {\text {Pre Caps Attack Power} - x}</math>

! colspan=5| Target Rate
Daytime Attack Cap often makes it important to utilize [[Combat#Artillery_Spotting_.28Post-Cap_Modifier.29|Artillery Spotting]] when possible to increase damage.  [[Combat#Night Combat|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.

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 (Post-Cap Modifier)===
 
*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 "<span style="color:rgb(0,0,0);font-family:verdana,arial,helvetica,sans-serif;font-size:11.818181991577148px;line-height:15.600001335144043px;">触接中".</span>
 
*Trigger conditions:
 
**More air control than Air Denial
 
**At least one carrier scout plane, seaplane scout, or torpedo bomber equipped.
 
***Seaplane bombers, Type 3 Spotter, and Ka-type Autogyros cannot perform contact.
 
**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 elegible equipped planes.
 
*Different types of planes have different trigger rates. They are roughly estimated as (if only one is equipped):

'''Notes'''
+
<references/>
*Type 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.
 
 
 
===Artillery Spotting (Post-Cap Modifier)===
 
*When the following conditions are all met for a ship, artillery spotting may occur '''during day battle'''.
 
**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 [[List_of_Seaplanes_by_stats|seaplane]] {{Template:Seaplane}} (i.e. slots are not all at 0 remaining).
 
 
 
*Factors affecting trigger chance
 
**Increases with combined fleet LOS (very roughly +0.08% per LOS)
 
**Flagships bonus of around +15%
 
**Air supremacy adds about +10% more than air superiority
 
*<span style="color:rgb(41,47,51);font-family:Arial,sans-serif;line-height:18px;white-space:pre-wrap;">Seaplane bombers can be used in artillery spotting. ([https://twitter.com/KanColle_STAFF/statuses/459604731564802048 25/4/2014] )</span>
 
*Ka-type Observation Autogyro does not work for artillery spotting.

===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.
  
<u>Single Attack</u>
+
* '''Line Ahead''': All-out surface combat formation.
*A ship will only do a single attack if
+
* '''Double Line''': All-around, high accuracy formation.
**only 1 main gun is equipped (e.g.{{Template:RedGunMedium}}{{Template:TorpedoWeapon}}{{Template:Radar}}).
+
* '''Diamond''': Anti-Air formation.
**no main guns are equipped (e.g. {{Template:YellowGun}}{{Template:YellowGun}}).
+
* '''Echelon''': Mixed surface-ASW combat formation.
**a double attack/cut-in was not triggered by chance.
+
* '''Line Abreast''': ASW formation.
*Damage: 100%
+
* '''Vanguard''': Defensive/evasive & anti DD/[[PT Imp]] formation (event only).
<u>Double Attack</u>
+
* [[Combined Fleet]] has other formations.
*A ship can do a double attack if
 
** 2 or more''' main guns''' equipped (e.g. {{Template:RedGunHeavy}}{{Template:RedGunHeavy}}).
 
*Damage: 120 % x 2 
 
*Trigger chance: '''~50%'''
 
<u>Cut-in Attack</u>
 
  
[[File:KanColle-140425-17422431.png|thumb|Cut-in Type Observed Fire using 1Main 1Sec & Type 91 AP shell]]
 
*A ship can do a cut-in attack if
 
*#equipped with '''1 main gun and 1-2 secondary guns (without AP shell/Radar)''' (e.g. {{Template:RedGunHeavy}}{{Template:YellowGun}}).
 
*#*Damage: 110 %
 
*#equipped with '''1 main gun, 1 secondary gun and 1 radar '''(e.g. {{Template:RedGunHeavy}}{{Template:YellowGun}}{{Template:Radar}}).
 
*#*Damage: 120%
 
*#equipped with '''1 main gun, 1 secondary gun and 1 [[Type 91 Armor-Piercing (AP) Shell]]'''.
 
*#*Damage: 130 %
 
*Cut-in attacks receive an accuracy bonus.
 
*Trigger chance: '''~50%'''
 
<u>Mixed Attack</u>
 
[[File:KanColle-140425-16133343.png|thumb|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
 
*#equipped with '''2 main guns + 1 secondary gun '''(e.g. {{Template:RedGunHeavy}}{{Template:RedGunHeavy}}{{Template:YellowGun}}).
 
*#*Cut-in damage:  130 %
 
*#*Double attack damage: 120 % x 2
 
*#equipped with '''2 main guns + 1 [[Type 91 Armor-Piercing (AP) Shell]]'''.
 
*#*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.
 
  
 +
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.
  
Notes:
+
=Victory Conditions=
*Luck {{Template:Luck}} and sparkling do not affect the trigger chance of artillery spotting.
+
Once the battle ended, a damage gauge is displayed on the post-combat screen for each allied and enemy fleet, using the following calculation:
*Artillery spotting cut-in attacks cannot miss, but they will inflict scratch damage instead.
 
*[[Type 3 Shell]] {{Template:GreenAmmo}}, [[List of Torpedoes by stats|torpedoes]] {{Template:TorpedoWeapon}} and [[List of Anti-Air Guns by stats|machine guns]] {{Template:GreenGunMG}} do not count toward triggering artillery spotting.
 
*Tables of [[List_of_Main_Guns_by_stats|main guns]] and [[List_of_Secondary_Guns_by_stats|secondary guns]]
 
  
 +
{{Formula
 +
|Title=Gamage Gauge Formula
 +
|Math=\text{Damage}_\text{%} = \frac{\text{Fleet}_\text{HP lost} }{\text{Fleet}_\text{HP} }

*In general, two bars of {{Ammo}} 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 {{Ammo}} 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' whirpools decrease your resources directly, later maps will decrease either {{Fuel}} or {{Ammo}} 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.
 
 
==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.
 
*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
 +
* 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. 
  
 +
==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]]''.
  
'''Notes'''
+
The way MVP is determined is:
*The Minimum Sunk Requirement:
+
* The girl who deals the highest total damage (sum of all attacks during the combat) is awarded MVP. This damage is not weighted.
** 4 ships out of a fleet of 6
+
* If multiple girls are tied for damage, the MVP goes to the topmost girl in the fleet order.
** 3 ships out of a fleet of 5
+
* If the ship achieving the most damage would be sunk in the battle, MVP is rewarded to the next highest damage dealer instead.
** 2 ships out of a fleet of 4
+
** As such, if no damage is dealt to the enemy, the flagship automatically receives MVP.
** 2 ships out of a fleet of 3
+
* Battles ending in an E-Rank have no MVP.
** 1 ship out of a fleet of 2
+
* In a Combined Fleet, each fleet has its own independent MVP.
*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.

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:

  2. Fleet's Jet Assault
  3. Land-Based Aerial Support

  5. 2nd Shelling Phase
  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.

Notes
  • 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%
3 37,50% 28,00% 8,33% 6,13%
4 37,50% 28,00% 25,00% 20,40%
5 28,00% 25,00% 20,40%
6 25,00% 20,40%
7 20,40%

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.


Other mechanics available on this menu:

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.
