Night Battle Breakdown
If your fleet pursues the enemy into Night Battle (夜戦, yasen), or you enter a special Node such as a Night Node or a Night to Day Node, your fleet will fight at night.
The Night Battle has the following structure:
- Night Contact and Spotting
- Night Shelling Phase
Other phases that may happen before Night Shelling Phase:
- Support Expedition (if the battle starts at night)
- Allied Friendly Fleet Phase
In case neither fleets meet the requirements, the sub-phase will be skipped.
Night Contact and Spotting
When the fleet is equipped with certain equipment, additional effects are triggered for the duration of the Night Battle. The equipment that influence the battle in such ways are Searchlight, Large Searchlight, Star Shell and Night Scout.
More information on the actual effects of each piece of equipment can be found in the Night Shelling Special Attacks section.
Equipment | Effect | Requirement(s) |
---|---|---|
Star Shell | ||
Searchlight |

Skilled Lookouts |

Night Shelling Phase
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 + stats instead of only .
- Heavily damaged (大破) (Taiha?) and sunk ships are unable to participate in battle.
- All types of Aircraft Carriers are unable to participate in battle, unless they are equipped with a Night Operation Aviation Personnel.
- Saratoga Mk.II, Akagi Kai Ni E and 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.
- 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.
- Ships with 0 + stats are unable to participate in battle.
- Currently, this is only observable against the Wa-Class Transport Ship.
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.
In addition to that, Night Battle is not affected by the Day Battle's Engagement form.
Night Special Attacks
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 in 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, etc.
Compared to its Day Battle counterpart Artillery Spotting, Cut-ins require no special conditions such as 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 have no influence on the damage output.
Cut-ins may be activated during a ship's turn and will override its normal single attack.
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 on the remaining slots. Be wary that adding certain equipment may change the Cut-in you would be rolling for. If your setup fulfils 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.

- Note that small caliber such as 10cm Twin High-angle Gun + AAFD and 5in Single Gun Mk.30, as well as Atlanta's 5in Twin Dual-purpose Gun Mount (CD) are not Secondary but Main Guns.

- Note that Minisubs such as Type A Kouhyouteki are not Torpedoes.

"New Type" Cut-ins
The "New Type" Cut-ins are the Cut-ins introduced with the implementation of Saratoga Mk.II onwards. From bottom to top, 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 Carrier Cut-ins require Night Operation capabilities either passively (granted by a specific remodel) or granted by equipping a Night Operation Aviation Personnel. Carriers that can perform Surface Shelling attacks at night will not perform Carrier Cut-ins without said Night Operation capabilities.
If not applicable, ships will skip rolling for "New Type" Cut-ins altogether and only roll for Original Types instead.

- By using a second 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 Tashkent Kai.
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 bottom-most that meet the prerequisites. If this roll fails, the ship will perform a Single Attack.

Mixed Torpedo Cut-in | Additional allowed | 1.3 | 2 | |

Single Attack
If all rolls fail or the ship meets no Cut-in requirements, then it'll perform a Single Attack: a default 1 hit, no damage modifier attack.
Trigger Rates
The chance of successfully rolling a Cut-in and performing the attack is given by:
[math]\displaystyle{ \text{CI %} = \left[ \dfrac{\text{Base}_\text{ship}}{\text{Base}_\text{attack}} \right] \times 100 }[/math]
Where:
[math]\displaystyle{ \text{Base}_\text{ship} = \lfloor 15 + \text{Luck} + 0.75 \times \sqrt{\text{Level}} + \text{Modifiers}\rfloor }[/math] , if the Ship's Luck stat is less than 50.
[math]\displaystyle{ \text{Base}_\text{ship} = \lfloor 65 + \sqrt{ \left( \text{Luck} - 50 \right) } + 0.8 \times \sqrt{\text{Level}} + \text{Modifiers}\rfloor }[/math] , if the Ship's Luck stat is 50 or greater.
Modifiers is the sum of various equipment modifiers. Do note that modifiers change based on the Cut-in that is being used:
Modifier | Value | % | ||||
---|---|---|---|---|---|---|
Gun Cut-in | Mixed Gun Cut-in | Torpedo Cut-in | Mixed Torpedo Cut-in | |||
Placement | Flagship | 15 | 10.7% | 11.5% | 12.3% | 13% |
Other | 0 | |||||
Health | Moderate damage (中破 Chuuha) |
18 | 12.9% | 13.8% | 14.8% | 15.7% |
Any other health state | 0 | |||||
Searchlight | Allied | 7 | 5% | 5.4% | 5.7% | 6.1% |
Enemy | -5 | -3.6% | -3.8% | -4.1% | -4.3% | |
Large Searchlight | Allied | ? | ||||

Star Shell | Allied | 4 | 2.9% | 3.1% | 3.3% | 3.5% |

Skilled Lookouts | Allied | 5 | 3.6% | 3.8% | 4.1% | 4.3% |
Enemy | 0 |
[math]\displaystyle{ \text{Base}_\text{attack} }[/math] is the Value used by each type of Cut-in:
[math]\displaystyle{ \text{Base}_\text{attack} }[/math] | Value | % per Base Value |
---|---|---|
Destroyer Only (Torpedo-Radar-Lookout) | 150 | 0.66% |
Gun Cut-in | 140 | 0.71% |
Mixed Gun Cut-in | 130 | 0.77% |
Destroyer Only (Gun-Torpedo-Radar) | 130 | 0.77% |
Torpedo Cut-in | 122 | 0.82% |
Mixed Torpedo Cut-in | 115 | 0.87% |
Additional Notes:
- Due to the formula's parameters, the effect of 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.
