Fighter Combat
$$\text {Fighter Power} = \sum^\text{All slots} \text{Floor(} \sqrt{\text{Number planes in slot}} \times \text {Plane anti-air stat} + \text{Aircraft Proficiency Bonus} \text{)}$$


 * 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.
 * Aircraft Proficiency is factored into Fighter Power on top of the above formula. The exact formula is under investigation.
 * 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%.
 * As this is applied per slot, 80% of one enemy bomber group can be shot down while a second has 0% shot down.
 * Planes loaded on moderately/heavily damaged carriers can still join this stage of fighter combat.
 * 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 stages can eliminate more bombers.
 * If the enemy fleet launches no fighters and any planes are launched from either side, the result defaults to Air Supremacy. If both sides launch no planes, then the rest of the battle is treated the same as if Air Parity was achieved.

Fleet Anti-air Defense
The Fleet Anti-air Defense system was updated on 14 November 2014, alongside the addition of the Anti-air Cut-in system. It was then patched on 26 June 2015 to fix several bugs.

System Mechanics The numbers of planes shot down are given by the equations below:
 * Each enemy bomber slot is assigned at random to a defending ship.
 * Those ships then, for each assigned enemy slot, have two approximately 50% sequential chances to shoot down enemy planes.
 * The first chance (termed Proportional Air Defense) can shoot down a number proportional to the initial size of the enemy bomber squadron after anti-bomber combat.
 * The second chance (termed Fixed Air Defense) can shoot down a fixed number of enemy bombers determined by stats and equipment only.
 * Finally, one bomber from each enemy squadron will always be shot down regardless of success or failure of the previous two chances.

$$\text{Adjusted AA} = \text{Ship Base AA } + \sum^\text{Defender Slots}\text{Floor(Equipment Modifier} \times \text{(Equipment AA} + 0.7 \times \sqrt{ \text{Equipment Upgrade}}\text{))}$$

$$\text{Proportional } \texttt{\#} \text{ Shot Down} = \text{Floor(Floor(} 0.9 \times \text{Adjusted AA)} \text{/} 360 \times \text{Enemy Bomber Group Size)}$$

$$\text{Fixed } \texttt{\#} \text{ Shot Down} = \text{Floor(}\text{Adjusted AA} \text{/} 10 \text{)}$$

Formation Modifiers

 * As of the 26 June 2015 update, formations affect anti-air defense, but the exact effects are not yet clearly known. Prior to this update, a bug prevented formations from affecting anti-air calculations.

Equipment Modifiers

 * There may be other types of equipment with modifiers that affect the air defense equations which are not yet known.
 * A bug prior to the 26 June 2015 update gave several equipment such as (red) main cannons and Type 3 Shells modifiers of 0. The current values are not yet known.

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 animation (shown on the right) appears before engaging the enemy fighters. However, the effect of an Anti-Air Cut-In does not affect the resulting air control state (AS+, AS, Air Parity or Denial), and calculation wise, it only takes effect after fighters engage bombers in air combat. With an AA Cut-In and a good anti-air composition, it is sometimes possible to obliterate all incoming bombers before they inflict any damage, and even prevent enemy carriers from attacking during the shelling phase (since they have 0 bombers left).

Although several ships can be equipped with an AACI setup in one fleet, only one ship can perform an AACI during the aerial phase. The number of planes shot down is dependent on the ship performing the AACI and their equipment. Bringing more AACI capable ships will NOT increase the number of planes shot down via AACI.

Akizuki-class destroyers and Maya Kai-2 have a hidden bonus to certain AA Cut-in setups which increases the effectiveness tremendously.

In PVP Exercises, opposing fleets can do AA Cut-Ins, but the animation is not shown.
