Fighter Combat

[math]\displaystyle{ \text {Fighter Power} = \sum^\text{All slots} \text{Floor(} \sqrt{\text{Number planes in slot}} \times \text {Plane anti-air stat} \text{)} }[/math]

• Fighter planes, and specific Torpedo / Dive / Seaplane bombers with an +AA stat participate in the Fighter Combat.
• Recon planes (carrier based or seaplane recon) will NOT participate in Fighter Combat.
• The allied fleet and enemy fleet's Fighter Powers are compared to determine the result of Fighter Combat:

Fighter Power (FP = Own Fighter Power, EFP = Enemy Fighter Power)	Result	Text Display	% Shot Down	Contact	Artillery Spotting	Night Spotting
FP ≥ 3×EFP or Enemy Failed Detection or EFP=0 and Planes launched	Air Supremacy (AS+)	制空権確保! Seikuuken Kakuho!	0~90%	Allied only	Allied only	Allied only
3×EFP > FP ≥ 1.5×EFP	Air Superiority (AS)	航空優勢! Koukuu Yuusei!	0~80%	Both sides	Allied only	Both sides
1.5×EFP > FP ≥ 2/3×EFP or Aerial Combat Stage did not occur	Air Parity	No text displayed	0~60%	Both sides	Impossible for either side	Impossible for regular combat nodes Both sides for PvP as well as Night Combat Only nodes
2/3×EFP > FP ≥ 1/3×EFP	Air Incapability	No text displayed	0~40%	Both sides	Enemy only	Both sides
FP < 1/3×EFP	Air Denial	制空権喪失! Seikuuken Soushitsu!	0~10%	Enemy only	Enemy only	Enemy only

• 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%.
• As this is applied per slot, 80% of one enemy bomber group can be shot down while a second has 0% shot down.

• 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 triggering Contact.
• Even if allied planes secure air supremacy, planes can still be lost (up to 10%), and the subsequent anti-air defense stage can eliminate more bombers.

Anti-Air Cut-In

An Anti-Air Cut-In

Certain equipment combinations will provide a chance for an Anti-Air Cut-In (AACI) during the aerial combat. When activated, the cut-in CG (shown on the right) would appear before engaging the enemy fighters, but does not appear to affect the resulting air control state (AS+, AS, Air Parity or Denial). Although there's currently no conclusion on how it's applied onto the Fleet Anti-air Defense formula, a general consensus suggests the effectiveness scales with the AA stat () of the ship triggering it.

Requirement

• One of the following sets:
  1. Heavy Main Gun, Type 3 Shell , plus Anti-Aircraft Fire Director (AAFD)
     • Can be supplemented with an AA RADAR
     • Only available for BB(V)s due to Heavy Gun requirement.
  2. High-Angle mount (main gun or secondary) plus AAFD
     • Can be supplemented with an AA RADAR
     • Achievable by any surface ship.
  3. 10cm Twin High-angle Mount + AAFD plus AA RADAR
     • Can be supplemented with an HA mount or another 10cm Twin High-angle Mount + AAFD
     • Available to any ship capable of equipping a Light Main Gun.
  4. 25mm Triple Autocannon Mount (Concentrated Deployment), AA Gun (any) , plus AA RADAR
     • Achievable by any surface ship.
  5. Either 12.7cm Twin High-angle Mount + AAFD or 90mm Single High Angled Gun, plus AA RADAR
     • Can be supplemented with an High-angle Mount + AAFD
     • As both 12.7cm Twin High-angle Mount + AAFD and 90mm Single High Angled Gun are considered secondary guns, only ships capable of equipping them may use this setup.

• Akizuki has a built-in AA fire director, which allows her to trigger AACI without an AAFD with the following setup

• High-Angle mount (any) plus either or both:

• RADAR (any kind)
• High-Angle mount (any)

• Maya Kai 2 may trigger AACI with a unique setup:

• 25mm Triple Autocannon Mount (Concentrated Deployment), plus High-Angle mount (any)

• Can be supplemented with an AA RADAR

Notes

• 10cm Twin High-angle Mount + AAFD, 12.7cm Twin High-angle Mount + AAFD and 90mm Single High Angled Gun can substitute for a regular High-angle mount. Their built-in AAFD functions when paired with an AA RADAR.
• Slots otherwise empty can be equipped with anything else without disabling the Anti-Air Cut-In.
• A maximum of 1 ship will perform AACI per battle (regardless of how many ships are capable of doing so, or whether it is a Combined Fleet engagement), and due to AA stat of the ship performing the cut-in affecting the number of planes shot down, it may be desired to limit the number of ships with AACI setup.
• Successful enemy AACI will not display; typically, greater than normal losses of planes after a battle can be contributed to enemy AACI.
• Does not affect the determination of Air Superiority.
• Cannot shoot down pure enemy fighters, as usual.

Effect

• Provide an AoE blast on all the incoming enemy bombers, from the ship who is triggering it. (source 1, 2, 3)

Trigger Chance

• AA stat () of the ship performing the cut-in (equipment bonuses included) affects trigger rate. The correlation seems to be about +0.4% trigger rate for every point of AA ? (source 1, 2)
• Air radars provide marginal bonuses on AACI:

• For HA + AAFD setup, Air radar on CA does not increase the trigger chance on a large scale ??. (source)
• Type 13 Air radar Kai on Akizuki (and other DDs?) increases the trigger chance by ~10%. When AACI was activated, it also helps with shooting down more bombers. (source)

With an AA Cut-In from a ship with high AA stat (), it is possible to obliterate all incoming bombers before they inflict any damage, and even prevent opposing carriers from shelling since they have 0 bombers left. In PVP Exercises, opposing fleets can do AA Cut-Ins, but the animation is not shown.

There are reports that enemy ships in map 6-2 might be capable of doing AACI. Other than that, there is currently no enemy ship capable to blast all your bombers with AA weapons.

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:

[math]\displaystyle{ \text{Shot Down} = \text{Floor((Ship AA } + \text{Floor(Fleet Anti-air} \times \text{Formation Modifier))} \times 0.2125\text{)} }[/math], where
[math]\displaystyle{ \text{Fleet Anti-air} = \text{Floor(} \sum^\text{All slots}\text{Equipment AA Bonus} \times \text{Equipment Modifier)} }[/math]

The "Fleet Anti-Air" bonus is the sum of every equipment slot of every ship in the fleet (including the defending ship).
