* All types of Aircraft Carriers are unable to participate in battle, unless they are equipped with a {{AviationPersonnel}}{{EquipmentLink|Night Operation Aviation Personnel}}.
+
* The [[Shooting Order]] is altered, with notably {{color|red|'''Heavily Damaged'''}}, [[Evacuation|evacuated]], and sunk ships performing an actionless turn.
** [[Saratoga|Saratoga Mk.II]], [[Akagi|Akagi Kai Ni E]] and [[Kaga|Kaga Kai Ni E]] have built-in Night Operation capabilities and do not require such equipment.
+
 
** [[Saratoga]], [[Ark Royal]], [[Graf Zeppelin]], [[Taiyou]] and [[Shinyou]] can perform Surface shelling attacks without any equipment. These attacks can be performed even if Moderately Damaged.
+
* CV(B/L) are unable to participate in night battles, unless specific requirements are met (''see [[#Carrier Night Attacks|below]]'').
* Shelling attacks that target submarines will always deal 0 damage, and default to '''scratch damage'''. This makes it not possible to sink a submarine during Night Battle.
+
 
** This rule is void if the player fleet is a '''Combined Fleet'''.

[[File:Nightbattle_Order.png|thumb|right|Example of engagement order during Night Battle]]

In addition to that, Night Battle is not affected by the Day Battle's [[Engagement]], but is still affected by the [[Formation]].
The firing order is defined when the Night Shelling Phase starts, and in contrast to Day Battle, will not skip over sunk and retreated ships, or ships that have no means of attacking under any circumstances, such as a carrier with no bombers equipped or a Wa-Class Transport Ship, for example. In such cases, the ship will perform an actionless turn instead.
+
 
 +
=Carrier Night Attacks=
 +
Normally carriers cannot attack at night unless certain conditions are fulfilled. There are three different kinds of carrier night attacks: Standard Shelling, Swordfish Night Attacks, and Carrier Night Air Attacks.
 +
 
 +
This is not to be confused with [[Combat/Artillery Spotting#Aircraft Carrier Cut-in|Carrier Cut-In Attacks]] which are for daytime shelling.
 +
 
 +
===Trigger Requirements===
 +
;Standard Shelling
 +
*Regardless of their equipment, those CV(L) are able to attack at night, using the [[Damage_Calculations#Surface_Night_Battle|'''surface night battle''']] attack formula:
 +
**Using the plane attack animation: {{Ship/Link|Kaga Kai Ni Go}}, the {{Ship/Link|Taiyou Kai Ni|Unyou Kai Ni|Shinyou Kai Ni|text=''Taiyou''-class Kai Ni|link_class=Taiyou}}, and {{Ship/Link|Lexington|Lexington/Kai|text=Lexington/Kai}},
 +
***Uses a plane attack animation (even when none is equipped, sending an "invisible plane"), unless using a cuit-in<ref name="Lyco">Will use the surface shelling animation when attacking the [[Lycoris Princess]] or the [[Abyssal Jellyfish Princess]], useless using a cut-in or NOAP.</ref>.
 +
**Using the surface shelling animation: {{Ship/Link|Graf Zeppelin|Graf Zeppelin/Kai|text=Graf Zeppelin/Kai}}, the {{Ship/Link|Saratoga}} (base),
 +
 
 +
* This attack '''can be triggered''' even when {{color|orange|'''moderately damaged (中破)'''}}.
 +
* The attack power is relatively weak.
 +
* [[Plane Proficiency]] will not affect the critical rate.
 +
* If the carrier can carry [[ASW Shelling]], it will focus on submarines if any are present.
 +
* May be set up to activate [[#Original Cut-ins|Cut-Ins]] like the Double Attack.
 +
 
 +
;Swordfish Night Attack
 +
* This is just limited to {{Ship/Link|Ark Royal|Ark Royal/Kai|text=Ark Royal/Kai}} when equipped with a {{Equipment/Link|Swordfish|Swordfish Mk.II (Skilled)|Swordfish Mk.III (Skilled)|text=Swordfish}}.
 +
* This attack '''cannot be triggered''' when {{color|orange|'''moderately damaged (中破)'''}}.
 +
* The attack power is calculated using the [[Damage_Calculations#Surface_Night_Battle|'''surface night battle''']] damage formula but '''only taking into account''' Ark Royal's base firepower and the Swordfish's stats and {{star}} improvements<ref>https://twitter.com/myteaGuard/status/1360886212274216963</ref>.
 +
** All other equipment stat/bonuses are ignored.
 +
** Swordfish fit bonuses are also ignored<ref>https://twitter.com/myteaGuard/status/1358025976374939649</ref>.
 +
** Will send a plane attack animation<ref name="Lyco"/>.
 +
* [[Plane Proficiency]] still affects the critical rate.
 +
* May be set up to activate [[#Original Cut-ins|Cut-Ins]] like the Double Attack.
 +
On a side note, unlike the browser version, on the [[Kancolle Arcade|arcade]] version the attack is very powerful.
 +

In addition to that, Night Battle is not affected by the Day Battle's Engagement form.
+
;Carrier Night Air Attack
 +
* When equipped with a {{AviationPersonnel}} '''{{Equipment/Link|Night Operation Aviation Personnel|Night Operation Aviation Personnel + Skilled Deckhands|text=NOAP}}''' along with at least one {{PurpleFighter}}{{PurpleBomber}}[[Night Plane]], all carriers are able to perform carrier night air attacks.
 +
**{{Category:Night Carriers}} They are {{Ship/Link|Saratoga Mk.II}}, {{Ship/Link|Akagi Kai Ni E}}, {{Ship/Link|Kaga Kai Ni E}}, and {{Ship/Link|Ryuuhou Kai Ni E}}.
 +
* Like day battle, CV(L) '''cannot trigger''' the attack when {{color|orange|'''moderately damaged (中破)'''}}, but CVB still can.
 +
* The attack power is calculated using the [[Damage_Calculations#Carrier_Night_Air_Attacks|'''carrier night air attack''']] formula.
 +
** Only the base stats of the carriers, the stats of the night planes, and the count of each night plane are taken into account.
 +
** Planes in 0-size slots are ignored.
 +
* [[Plane Proficiency]] still affects the critical rate.
 +
* It can trigger regardless of the result of the [[Aerial Combat#Fighter Combat|fighter combat]] phase in day.
 +
* It can trigger even if no bombers are left.
 +
* CV(L) will ignore submarines to target surface ships with this attack.
 +
** Uniquely, {{Ship/Link|Gambier Bay Mk.II}} will focus on submarines using a shelling attack
 +
** If the carrier can also natively carry out "Standard Shelling", and no other valid target is available, the carrier will switch back to the shelling against submarines.
 +
* May activate [[#"New Type" Cut-ins|Night Carrier Cut-Ins]].

=Night Special Attacks=

When using special equipment setups, ships may perform one of multiple special attacks at night. These attacks are often referred to as '''Cut-Ins''' due to the way the equipment is displayed on the screen before the attacks are performed. Particular cut-ins are often referred to by their acronym, such as TCI for Torpedo Cut-In, GCI for Gun Cut-In, DA for Double Attack, etc...

Compared to Day cut-ins (''[[Artillery Spotting]]''), Night cut-ins do not require any particular [[Air State]], relying solely on the equipment restrictions and the stats of the ship performing it.

* By using a second {{EquipmentLink|12.7cm Twin Gun Mount Model D Kai 2|text=12.7cm Model D Kai 2}} when performing a Destroyer Cut-in, an additional bonus of '''1.125x''' is applied multiplicatively to the attack. This setup can only be deployed on {{ShipLink|Tashkent/Kai}}.
+
;Derivated set-ups
 +
When using an {{Equipment/Link|Skilled Lookouts|text=SLO}} or {{Equipment/Link|Torpedo Squadron Skilled Lookouts|text=TSLO}} in the [[Reinforcement Expansion]], it is possible to "mix" the Destroyer Cut-ins, making 2 cut-ins available to trigger at once, and so increasing the odds of having at least one that activates during Night Battle.
 +
 
 +
Those set-ups are:
 +
*'''"GTRL"''': {{Light Gun}}{{TorpedoWeapon}}{{Surface Radar}}{{SurfaceShipPersonnel}}
 +
*'''"DTRL"''': {{Drum}}{{TorpedoWeapon}}{{Surface Radar}}{{Equipment/Card|Torpedo Squadron Skilled Lookouts|size=40px}}
 +
 
 +
''GTRL is sometimes referred to as "GUiTaRSolo" for "Gun, Torp, Radar, and Skilled Lookouts (SLO)".''
 +
 
 +
Do note that if a DD is equipped with a {{Surface Radar}} [[Surface Radar]] '''AND''' a {{SurfaceShipPersonnel}} {{EquipmentLink|Skilled Lookouts|Torpedo Squadron Skilled Lookouts|text=Skilled Lookout|link_category=Surface Ship Personnel}}, then it gain a post-cap [[Evasion|evasion bonus]] during Night Battle.

===Original Cut-ins===
 +
In contrast with the "New Type" Cut-ins, "Original" Cut-ins are only rolled once, even if multiple setup prerequisites are met. The setup used will be the '''top-most''' that meets the prerequisites. If this roll fails, the ship will perform a '''Single Attack'''.
  
In contrast with the "New Type" Cut-ins, Original Cut-ins are only rolled once, even if multiple setup prerequisites are met. The setup used will be the bottom-most that meet the prerequisites. If this roll fails, the ship will perform a '''Single Attack'''.

Night Battle Breakdown

The screen after Day Battle. Clicking "夜戦突入" on the right will begin Night Battle

When the fleet pursues the enemy into Night Battle (夜戦, yasen), or enters special Nodes such as Night Nodes or Night to Day Nodes, the fleet will fight at night.

The Night Battle has the following structure:

  1. Friendly Fleet (event only)
  2. Support Expedition (if the battle starts at night only)
  3. Night Contact and Spotting
  4. Night Shelling Phase

In case neither fleets meet the requirements, the sub-phase will be skipped.

Night Contact and Spotting

Star Shell, Searchlight, and Night Recon activated. The Night Recon is displayed on top of the Enemy "Radar".

When the fleet is equipped with certain equipment, additional effects are triggered for the duration of the Night Battle. The relevant equipment and their effect are listed below.

Equipment Effect Requirements

Night Reconnaissance Seaplane Night Recons
  • The recon cannot trigger on a slot of size 0.
  • The success rate is dependent on the level of the ship it is equipped on.
  • Trigger is determined by:
[math]\displaystyle{ \text{Triggers %} = 4 \times \bigg\lfloor \sqrt{\text{LoS}} \times \sqrt{\text{LV}} \bigg\rfloor }[/math]
  • With:
    • [math]\displaystyle{ \text{LoS} }[/math] the base LoS Line of Sight of the recon (excluding Improvements Improved and fit bonuses),
    • [math]\displaystyle{ \text{LV} }[/math] the Level of the ship carrying the Night recon.
    • Like Day Contact, if multiple night recons are in the fleet, each will have a chance to trigger, in base accuracy order.
  • If the Night Battle was preceded by a day battle:
    • The Air State must be AD, AS or AS+.

Night Shelling Phase

Example of engagement order during Night Battle

Following the battle preliminary stages, Night Shelling proper will begin. Similar to Day Battle, attacks performed by ships are shelling attacks.

Some rules are applied to shelling attacks:

  • Attack power is defined by Firepower + Torpedo Attack stats instead of only Firepower.
    • It is often represented with the Night Battle Power "Night Battle Power" (Yasen) icon.
    • If the enemy is unaffected by torpedoes, such as installations, only Firepower is used instead.
  • The Shooting Order is altered, with notably Heavily Damaged, evacuated, and sunk ships performing an actionless turn.
  • CV(B/L) are unable to participate in night battles, unless specific requirements are met (see below).
  • Shelling attacks that target submarines will always deal Scratch Damage, making it impossible to sink submarines during Night Battle.
    • This rule is void if the player's fleet is a Combined Fleet.
    • Friendly Fleets can also ignore this rule, and may damage submarines.

In addition to that, Night Battle is not affected by the Day Battle's Engagement, but is still affected by the Formation.

Carrier Night Attacks

Normally carriers cannot attack at night unless certain conditions are fulfilled. There are three different kinds of carrier night attacks: Standard Shelling, Swordfish Night Attacks, and Carrier Night Air Attacks.

This is not to be confused with Carrier Cut-In Attacks which are for daytime shelling.

Trigger Requirements

Standard Shelling
  • This attack can be triggered even when moderately damaged (中破).
  • The attack power is relatively weak.
  • Plane Proficiency will not affect the critical rate.
  • If the carrier can carry ASW Shelling, it will focus on submarines if any are present.
  • May be set up to activate Cut-Ins like the Double Attack.
Swordfish Night Attack
  • This is just limited to Ark Royal/KaiArk Royal
    Ark Royal Kai
    when equipped with a SwordfishSwordfish
    Swordfish Mk.II (Skilled)
    Swordfish Mk.III (Skilled)
    .
  • This attack cannot be triggered when moderately damaged (中破).
  • The attack power is calculated using the surface night battle damage formula but only taking into account Ark Royal's base firepower and the Swordfish's stats and Improved improvements[2].
    • All other equipment stat/bonuses are ignored.
    • Swordfish fit bonuses are also ignored[3].
    • Will send a plane attack animation[1].
  • Plane Proficiency still affects the critical rate.
  • May be set up to activate Cut-Ins like the Double Attack.

On a side note, unlike the browser version, on the arcade version the attack is very powerful.

Carrier Night Air Attack
  • When equipped with a Aviation Personnel NOAPNight Operation Aviation Personnel
    Night Operation Aviation Personnel + Skilled Deckhands
    along with at least one Night FighterNight Torpedo BomberNight Plane, all carriers are able to perform carrier night air attacks.
  • Like day battle, CV(L) cannot trigger the attack when moderately damaged (中破), but CVB still can.
  • The attack power is calculated using the carrier night air attack formula.
    • Only the base stats of the carriers, the stats of the night planes, and the count of each night plane are taken into account.
    • Planes in 0-size slots are ignored.
  • Plane Proficiency still affects the critical rate.
  • It can trigger regardless of the result of the fighter combat phase in day.
  • It can trigger even if no bombers are left.
  • CV(L) will ignore submarines to target surface ships with this attack.
    • Uniquely, Gambier Bay Mk.IIGambier Bay Mk.II will focus on submarines using a shelling attack
    • If the carrier can also natively carry out "Standard Shelling", and no other valid target is available, the carrier will switch back to the shelling against submarines.
  • May activate Night Carrier Cut-Ins.

Night Special Attacks

When using special equipment setups, ships may perform one of multiple special attacks at night. These attacks are often referred to as Cut-Ins due to the way the equipment is displayed on the screen before the attacks are performed. Particular cut-ins are often referred to by their acronym, such as TCI for Torpedo Cut-In, GCI for Gun Cut-In, DA for Double Attack, etc...

Compared to Day cut-ins (Artillery Spotting), Night cut-ins do not require any particular Air State, relying solely on the equipment restrictions and the stats of the ship performing it. Do note that the specific equipment being shown during the cut-ins animation have no influence on the damage output.

Cut-ins may be activated during a ship's turn and will override its normal single attack.

In addition, all "Special Attacks" (Touches) can trigger at night, with the "Kongou-class Night Assault" being only available during night battle.

Setups and Attack Types

Different setups have different conditions, trigger rates, damage, and number of hits. Cut-ins are solely determined by the attack's prerequisites.

For a given cut-in, any other equipment can be added to the remaining slots. Be wary that adding certain equipment may change the Cut-ins rolled for. If the setup fulfills multiple prerequisites, the Cut-in closer to the bottom of the list will be used. Additionally, each ship will roll for "New Type" Cut-ins first, if possible.

Special attacks that hit twice will roll independently to determine hit, critical chance, and armor penetration. Although their animations appear as single hits, Torpedo Cut-In, and Mixed Torpedo Cut-In are actually composed of 2 separate hits, with their damage added together in-game.

"New Type" Cut-ins

Uranami performing a DD-exclusive Torpedo/RADAR/Lookout Cut-in, or TRL for short.

The "New Type" Cut-ins are the Cut-ins introduced with the implementation of Saratoga Mk.II onwards. From top to bottom, each eligible Cut-in will be rolled if the previous roll has failed. If all rolls fail, then an additional single roll for a "Original Type" Cut-in is performed.

Do note that Night Carrier Cut-ins require a CV(L/B) with Night Operation capabilities by either equipping a NOAPNight Operation Aviation Personnel
Night Operation Aviation Personnel + Skilled Deckhands
or being a CVN.

  • Carriers that can perform Surface Shelling attacks at night will not perform Carrier Cut-ins without said Night Operation capabilities.
Night Zuiun CI
  • Can only be triggered on BBV, CAV, CL, or AV[1].
  • The ship must not be more than lightly damaged (小破).
  • Performs 2 attacks against random enemies.
    • The same enemy can be targeted twice.
  • Drops a Star Shell during the attack.


If not applicable, ships will skip rolling for "New Type" Cut-ins altogether and only roll for "Original Types" instead.

Derivated set-ups

When using an SLOSkilled Lookouts or TSLOTorpedo Squadron Skilled Lookouts in the Reinforcement Expansion, it is possible to "mix" the Destroyer Cut-ins, making 2 cut-ins available to trigger at once, and so increasing the odds of having at least one that activates during Night Battle.

Those set-ups are:

  • "GTRL": Small Caliber Main GunTorpedoesSurface RADARSurfaceLookout
  • "DTRL": Drum CanisterTorpedoesSurface RADARSurfaceEquipment Card Torpedo Squadron Skilled Lookouts.png

GTRL is sometimes referred to as "GUiTaRSolo" for "Gun, Torp, Radar, and Skilled Lookouts (SLO)".

Do note that if a DD is equipped with a Surface RADARSurface Surface Radar AND a Lookout Skilled LookoutSkilled Lookouts
Torpedo Squadron Skilled Lookouts
, then it gain a post-cap evasion bonus during Night Battle.

Original Cut-ins

In contrast with the "New Type" Cut-ins, "Original" Cut-ins are only rolled once, even if multiple setup prerequisites are met. The setup used will be the top-most that meets the prerequisites. If this roll fails, the ship will perform a Single Attack.

Single Attack

If all rolls fail or the ship meets no Cut-in requirements, then it will perform a "Single Attack", a default 1 hit shelling attack, with no particular damage or accuracy modifier.

Trigger Rates

Trigger rate formula
[math]\displaystyle{ \begin{cases} \text{Trigger %}_\text{Cut-in} = & \dfrac{\lfloor 15 + \text{Base}_\text{ship} + \text{Modifier} \rfloor }{\text{Base}_\text{attack} } \times 100 \\ \text{Luck} \lt 50 & \text{Base}_\text{ship} = 0.75 \times \sqrt{\text{Level} } + \text{Luck} \\ \text{Luck} ⩾ 50 & \text{Base}_\text{ship} = 0.80 \times \sqrt{\text{Level} } + 50 + \sqrt{\text{Luck} - 50 } \end{cases} }[/math]
With
  • [math]\displaystyle{ \text{Level} }[/math] the ship's level ,
  • [math]\displaystyle{ \text{Luck} }[/math] the ship's Luck luck stat,
  • [math]\displaystyle{ \text{Modifiers} }[/math] is the sum of various equipment modifiers (see the below table for value).
    • Modifiers change based on the cut-in that is being used.
    • Modifiers can affect the enemy fleet.
  • [math]\displaystyle{ \text{Base}_\text{attack} }[/math] is the Value used by each type of Cut-in. See the above tables for value.
Notes
  • The effect of Luck over 51 is negligible due to diminishing returns, thus going above such value is generally discouraged.
  • The formula used above was datamined from KanColle Kai and is corroborated by test results in the browser version.
