Night Battle Intro

Entering Night Battle

In the scenario that the enemy fleet has not been defeated yet during Day Combat, the player has the choice to pursue them in a Night battle (夜戦) to finish them off. Ships who utilizes both Firepower and Torpedo stats have a drastically increased strength, giving them a stronger edge against the tougher armored opponents. The damage soft cap is raised to 300 during the night, allowing your ships to effectively unleash even more damage to your opponents. Bombers cannot attack during the night, unless they are equipped with the Night Operation Aviation PersonnelNight Operation Aviation Personnel 258 Card or the Night Operation Aviation Personnel + Skilled DeckhandsNight Operation Aviation Personnel + Skilled Deckhands 259 Card (exceptions being Saratoga Mk.IISaratoga Mk, Ark RoyalArk Royal, Graf ZeppelinGraf Zeppelin and Taiyou Kai NiTaiyou Kai Ni).

The common way of entering a night battle is by selecting 夜戦 at the end of a day battle, although there exists nodes that forces the fleet to immediately start in a night battle. Battles that start during a night battle will not transition to a day battle usually, but such nodes do exist.

Night Battle Effects[]

During night battle, the following effects are applied:

General[]

  • The ammo usage on that node is increased by 50% if night battle is entered from day. As most nodes on normal and event maps alike uses 20% ammo, this will be increased to 30% for example.
  • Night battle damage depends on both the Firepower and Torpedo Attack stats for attack power. Consequently, DDs, CLs, CLTs and CAs have drastically increased strength at night.
  • Any vessel that is heavily damaged (大破), is not allowed to attack during the night.
  • 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.
  • All ASW attacks during night battle are reduced to scratch damage. This means that submarines are impossible to kill during night, as you cannot sink a ship with scratch damages. However, in battles starting at night and/or Combined Fleet sorties, ASW damage will apply as normal.
  • With the exception of Vanguard, formation damage modifiers and Engagement Form damage modifiers do not apply in Night Battle (i.e., they are always 100%).

Night Buffs[]

  • All CA(V)s gain a +5 Evasion.
  • All CA(V)s equipped with the 20.3cm series guns20.3cm Twin Gun Mount 006 Card20.3cm (No.2) Twin Gun Mount 090 Card20.3cm (No.3) Twin Gun Mount 050 Card gain an accuracy boost (applied after modifiers, but before the hit rate cap).
  • Destroyers equipped with RadarSurface Radar and Skilled LookoutsSkilled LookoutsSkilled Lookouts 129 Card will gain an evasion bonus.

The following night equipment buffs can trigger when equipped. Keep in mind that only one of them triggers if your fleet contains duplicate equipment (e.g. 2 searchlights, 2 starshells).

  • Increase the Accuracy of your fleet.
  • Increase the cut-in rate of your fleet.
  • Decrease the cut-in rate of the enemy fleet.
  • Ship must have at least 5 Health
  • Trigger rate is 70% each.

  • Increase the cut-in rate of your fleet.
  • Decrease the cut-in rate of the enemy fleet.
  • The evasion of the ship equipped with it is sharply reduced and is attacked more often by the enemies.
  • Ship must have at least 2 Health
Skilled LookoutsSkilled LookoutsSkilled Lookouts 129 Card

  • Increase the Accuracy of your fleet.
  • Increase the Firepower of your fleet by +5.
  • Increase the critical hit rate of your fleet.
  • The recon is not equipped on a 0 slot.
  • The air control is either AD, AS or AS+.
  • The air control is either AD, AP, AS or AS+ in PvP.
  • The success rate is dependent on the level of the ship it is equipped on.


While entering a night battle offers many benefits, keep in mind that this also applies to your opponents! Enemy destroyers who aren't as much as a threat during the day will also gain a huge increase in firepower during the night, so be careful that you don't end up on the short end of the stick.

Night Battle Special Attacks[]

Night battle special attacks allow your ship to Double Attack (DA) and Cut-In (CI) at night. Compared to artillery spotting, these special attacks are less demanding on equipment setups and give different bonuses. Note that it is important to realize the differences between the two types of special attack and know when to use which.

Requirements[]

  • Not in heavily damaged (大破) state.
  • CV(L) performing the attack is not in moderate damage (中破) state.
  • Certain equipment setups (see below).

Setups and Attack Types[]

Different setups have chances to trigger different attack types. Attack types are only determined by the prerequisites.

  • Large Caliber Main Gun is used to indicate a Main Gun. Small Caliber Main Gun is used for Destroyer Cut-Ins.
  • Auxiliary Gun is used to indicate a Secondary Gun.
  • Torpedo-based Weapon is used to indicate a Torpedo, note that KouhyoutekiCatbomb is not a torpedo.
  • For Carrier Cut-Ins (note that placeholders are used in order to avoid confusion):
  • For a given attack type, any other equipment can be added on the remaining slots, as long as it does not switch the attack type. Feel free to add any auxiliary equipment (Armor Piercing Ammunition AP shell, Seaplane Seaplane, Anti-aircraft Point-defense Weapon Anti-Air Gun, etc.).
  • When your set up fulfills the prerequisites for multiple attack types, the one closer to the bottom of the list will be used.
  • When the setup does not fulfill any prerequisites or when its special attack is not triggered, the ship will perform a normal single attack (one hit, no special damage modifiers).
  • Two hit attacks will have two independent chances to miss, hit or deal a critical hit, as well as two independent armor rolls. For Double Attacks the damage values are displayed as is for each hit twice, for two hit Cut-Ins they are displayed as a sum once.
  • The animation for ships equipped with 2 different torpedoes may be different but the damage output is always the same.

Night Double Attack Chance[]

Has a very high (~99%) and relatively consistent activation chance.[1] Activation rate 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.

Night Cut-In Chance[]

Torpedo Cut-In Rates (Vita)

Theoretical Torpedo Cut-In Rates

The probability of a Night Cut-In occurring is given by the general formula:

The result of which can be multiplied by 100 and interpreted as a percentage.

Where:

  • Level is the ship's level
  • Luck is the ship's luck
  • Type Factor: is a modifier defined by the cut-in type:

  • The effect of Luck over the cap is negligible, thus going over it is generally not recommended. Starting at 51 Luck, any extra luck will suffer from strong diminishing returns.
  • No bonus is received when ships enter light damage state.[2]
  • Marriage itself does not increase cut-in chances.[3]
  • The above formula originates from KanColle Kai[4]. Generally, it's close to the previously researched formula and is in agreement with the experimental data.[5][6][7]
    • According to this formula, torpedo cut-in types have higher probabilities than gun cut-in types.


Destroyer Cut In Properties[]

Destroyer Cut Ins are special Night Battle attack types unique to only Destroyers when they meet the proper equipment setups. Their properties are as follows:

  • When Destroyer Cut-In requirements are met, they will attempt to activate first before normal night attack types. In the case of failure, the game will then attempt to roll for any other Destroyer Cut-In setup they qualify for, and then finally rolling for the first normal Night Attack type the destroyer qualifies for.
    • This is different from normal night battle setups, which will only roll once for the highest priority attack type they qualify for.
    • For example, if a destroyer has Gun/Torpedo/Radar, the game will roll for the GTR Destroyer Cut-In, and if it fails, will roll again for Mixed Torpedo Cut-In, increasing the overall chance of cutting in.
  • Equipping 12.7cm Twin Gun Mount Model D Kai 2/312.7cm Twin Gun Mount Model D Kai 2 267 Card12.7cm Twin Gun Mount Model D Kai 3 366 Card can increase the damage multiplier of destroyer cut-ins, with one gun adding x1.25, and the second gun adding x1.125. Both modifiers are added multiplicatively, however, only TashkentTashkent is able to use the second gun multiplier due to equipment slots and cut-in equipment requirements.
