=Aerial Combat Breakdown=
Aerial Combat is one of the [[Day Battle]] intermediary phases. In this phase, allied and enemy fleets indirectly fight each other for aerial dominance and airstrike potential, granting either fleet some substantial advantages in the subsequent combat phases.
# Air Control - In this phase, the air control state is determined. This is important for determining if you can perform daytime special attacks and trigger night contact in normal day combat nodes. It also partly determines how many planes you lose.
Aerial Combat has the following structure:
# Contact - In this phase, eligible planes will attempt to trigger contact. If triggered, it will increase the damage of your airstrike.
#LBAS's [[#Jet Assault Phase|Jet Assault]]
#Fleet's [[#Jet Assault Phase|Jet Assault]]
# Airstrike - In this phase, any surviving bombers attack the enemy surface fleet. It is not affected by morale, engagement or formation.
#[[LBAS|Land-Based Aerial Support]]
#[[#Stage 1 - Battle for Air Superiority|Stage 1 - Battle for Air Superiority]]
#[[#Stage 2 - Fleet Anti-Air Defense|Stage 2 - Fleet Anti-Air Defense]]
#[[#Stage 3 - Airstrike|Stage 3 - Airstrike]]
If an [[LBAS]] phase happens before the Aerial Combat phase, the enemy fleet state, such as plane slots and Fighter Power used for the subsequent Aerial Combat, is carried over. This can be used to tamper with the Enemy's Aerial Combat initial conditions.
*''See [[LBAS]] for more details.
In case neither fleets meet the requirements, the sub-phase will be skipped.

=[[Jets|Jet Assault]] Phase=
Planes that participate in this phase:
* {{Template:JetFighterBomber2}},{{Template:JetFighterBomber1}} "Jets" (turbojet propelled fighter-bombers)
If any carrier on either side is equipped with [[Jets]], the '''"Jet Assault" (JA)''' Phase will commence first of all. The JA Phase may only commence during battles where '''Airstrikes''' can be performed. The JA follows the same rules as [[#Stage 3 - Airstrike|Stage 3]].
The defending side is allowed to defend against the Jets following the same rules as [[#Stage 2 - Fleet Anti-Air Defense|Stage 2]], however, Jets possess great [[#Anti-Air Resistance|Anti-Air Resistance]], specifically during the JA, and enemy [[AACI]] cannot be triggered during this phase either.
{| class="wikitable"
Jets also take part in the regular [[#Stage 3 - Airstrike|Stage 3]], but in exchange, they are subject to enemy Anti-Air prior to the JA, and again during [[#Stage 2 - Fleet Anti-Air Defense|Stage 2]].
'''Steel Cost:''' every time the Jet Assault Phase is triggered, {{Steel}} is ''automatically subtracted from the stockpile''.
<math>\text{Jet Phase Cost} = \sum^{\text{All Jets}} \lceil \text{Plane}_\text{Count} \times \text{Steel Cost} \rceil</math>
* <math>\text{Plane}_\text{Count}</math> is the current plane count '''at the start of the battle'''.
* <math>\text{Steel Cost}</math> is the steel cost per plane.
** [[Kikka Kai]]: '''2.6'''
** [[Jet Keiun Kai]]: '''2.8'''
=Stage 1 - Battle for Air Superiority=
[[File:Air_Superiority_Aquired.png|thumb|right|Green text at the bottom of the screen indicating an Air Supremacy result.]]
Planes that participate in this phase:
* Fighters:
** {{Fighter}}/{{Night Fighter Aircraft}} carrier-based,
** {{SeaplaneFighter}} seaplanes.
** {{IconText|{{ASWPlane}}|Hayabusa|8}} ASW Hayabusa
* Bombers
** {{Dive Bomber}}/{{Torpedo Bomber}}/{{Night Torpedo Bomber}}/{{JetFighterBomber1}}/{{JetFighterBomber2}} carrier-based,
** {{SPB}} seaplanes.
Following a possible Jet Phase, the fight for Air Supremacy will begin. The main objective of this phase is to define the '''Air State''' imposed on each fleet, by comparing each fleet's Air Power, more commonly referred to as '''Fighter Power (FP)'''.
*The Air State achieved can be critical, especially to trigger certain mechanics like [[Artillery Spotting]]/[[CVCI]], [[#Contact|Contact]], or [[Night Battle#Night Contact and Spotting|Night Contact]].
Fighter Power is defined by each plane equipped in the fleet that participates in this phase.
{{Formula
|Title=Fighter Power Formula
|Math=\text{Fighter Power} = \sum^{\text{All planes} } \left[ \left(\text{AA}_\text{Plane} \times \sqrt{\text{Plane}_\text{Count} } \right) + \text{Mod}_\text{proficiency} \right]
|Var=<math>\text{AA}_\text{Plane}</math> is the {{AA}} AA stat of the plane, including [[Improvement]]s.
** [[Visible Bonus]]es are not counted.
* <math>\text{Plane}_\text{Count}</math> is the number of planes in the slot prior to Stage 1's start.
* <math>\text{Mod}_\text{proficiency}</math> is the fighter-power proficiency bonus. For maxed proficiency {{Double Chevron}} planes it is:
** '''25.464''' for {{Fighter}} carrier-based [[Fighter]]s, {{SeaplaneFighter}} [[Seaplane Fighter]]s, and {{IconText|{{ASWPlane}}|Hayabusa|8}} {{Equipment/Link|Type 1 Fighter Hayabusa Model II Kai (20th Squadron)|Type 1 Fighter Hayabusa Model III Kai (Skilled/20th Squadron)|link=Liaison Aircraft|text=ASW Hayabusa}},
** '''9.464''' for {{SPB}} [[Seaplane Bomber]]s,
** '''3.464''' for all other planes.
** See ''[[Plane Proficiency]]'' for more details.
}}
After Fighter Power is calculated for each fleet ('''FP''' and '''EFP''' for allied and enemy fleets, respectively), the values are compared, and Air State is determined, based on the following:

;Notes
* Aircraft will be launched regardless of the carrier's state (except Sunk).
* The Air States between the allied and enemy fleets are mirrored. For example, attaining AS+ imposes AI to the enemy fleet.
* If both sides launch no planes, the Air State will be Air Parity.
* By solely using planes with no {{AA}} AA stat, an enemy fleet might start Air Supremacy Combat with 0 total Fighter Power.
** In such case, the allied fleet will attain AS+ even if no planes are launched.
=Stage 2 - Fleet Anti-Air Defense=
Planes that participate in this phase:
* Bombers
** AS: ≤5
** {{Dive Bomber}}/{{Torpedo Bomber}}/{{Night Torpedo Bomber}}/{{JetFighterBomber1}}/{{JetFighterBomber2}} carrier-based,
** AP: ≤3
** {{SPB}} seaplanes.
** {{ASWPlane}} [[Liaison Aircraft]] with {{Dive}} Dive Bombing stat.
** AD: 1
** Sunk carriers are ignored.
Following Stage 1, the Fleet AA Defense phase allows each fleet to reduce the incoming Airstrike damage by shooting down enemy planes.
[[file:Contact.png|thumb|right|The Tenzan (Murata Squadron) over the enemy Fleet Formation field shows that the plane successfully aquired contact]]
* Each bomber is assigned to a random enemy ship.
** Ships are picked regardless of damage state, ship class, and position in the fleet have no influence.
*** Even ships that cannot be targeted by airstrikes such as submarines can be chosen to defend against a given bomber.
*** Sunk ships cannot be chosen to defend<ref>https://twitter.com/Divinity_123/status/1564593185824841729</ref>, but sunk enemy ships can still activate [[#Anti-Air Cut-in|Anti-Air Cut-in]] for the fleet<ref>https://twitter.com/Divinity_123/status/1565631534362664960</ref>
* When a ship defends against a bomber, it rolls two concurrent but independent events, each with 50 % chance of success:
** The first roll, denominated '''Proportional Shootdown''', or '''Prop''' for short, reduces the slot size by a given % value.
** The second roll, denominated '''Fixed Shootdown''', or '''Fixed''' for short, reduces the slot size by a given X value.
** There is therefore a chance of 25 % to trigger both effects, 25 % to trigger only Prop, 25 % to trigger only Fixed, and 25 % to trigger neither, for each bomber.
** Player-side ships are also guaranteed to shoot down at least +1 plane in addition to this, see [[#Anti-Air Cut-in|Anti-Air Cut-in]] for details.

==Adjusted Anti-Air==
Adjusted Anti-Air is a set of values derived from each ship and the entire fleet. For a single ship, this value '''Ship Adjusted AA''' applies weights on different pieces of equipment to further increase its effectiveness against enemy air threats. For the fleet, this value '''Fleet Adjusted AA''' has the objective of further increasing the influence of particularly high Anti-Air ships on either side by strengthening the entire fleet's air defense performance.

===Anti-Air Resistance===
{{Category:Planes with Anti-Air Resistance}}
==Anti-Air Cut-in==
[[File:AkizukiAACI.png|thumb|right|Akizuki performing the ID 1 AACI.]]
Using special equipment setups, ships may perform one of multiple special Anti-Ait Cut-In mostly referred to as '''AACI''', during Stage 2.
;AACI types
*Each AACI is defined by its '''"ID"''' (its API value), and is arbitrary (''see the [[#AACI|below table]]'').
** They are then mostly referred to by their '''"ID"'''.
** ''Some older AACI may be referred to by their abbreviation, such as BBR for AACI 5.
* For all AACI, the '''"ID"''' therefore fully determines:
** The setup of the AACI and the ships able to trigger it,
** The "Trigger Rate" and the "Priority Order",
** The "K-value" and "shot down per slot" value,
;AACI effects
** AS+: <math>0.07</math>
* Grant a multiplier to the "Fixed Shootdown" of all allied ships, referred to as the ''K-value'', regardless of what ship triggers it,
** AS: <math>0.06</math>
* Remove a fixed number of planes from each enemy bomber slot ("shot down per slot").
These effects make depleting the entirety of enemy planes much more feasible.
'''Important Info'''
;AACI triggering
* If all planes fail to be selected, '''contact will fail to trigger'''. This means there are two points where your fleet can fail contact.
* Only one AACI can be performed per battle,
* If multiple planes share the same accuracy stat, the one equipped on the ship with the higher position in the fleet is checked first.
** On '''"[[Node|Aerial Combat Nodes]]"''', AACI can be triggered twice, one per phase.
* If a ship has multiple planes with the same accuracy stat, the one equipped in the higher equipment slot will be checked first.
* Only a ship equipped with proper AACI setups can trigger one (''see the [[#AACI|below table]]''),
* If multiple ships are equipped with AACI setups, each ship will roll their available AACI in '''ID's "Priority Order"''' (''see the [[#AACI|below table]]'').
** If IDs are tied, priority goes by fleet order from top to bottom.
** Thus, for a given fleet & setup, some ships will take priority over others always the same way.
** If one ship fulfills the requirement for multiple setups at once, then it will be able to roll each individual AACI in '''ID's "Priority Order"'''.
* The trigger rate is unaffected by [[Stats]] like the [[Stats#Health|damage status]], Fleet AA, Ship AA, Adjusted AA, Air State, or any other parameter like Luck and LoS.
* It is possible for all AACI rolls in a fleet to fail, triggering no AACI.
* If the enemy fleet has a valid setup, it may as well activate an AACI. If that happens, no animation will be shown, but the effects will function normally.
** It can activate during the regular airstrike phase, but not during other phases like the [[Jet Assault]]s, [[LBAS]] phases, [[OASW]], or [[Shelling]] phases.
** There is a bug that allows enemy ships to activate AACI even if they were sunk<ref>https://twitter.com/Divinity_123/status/1565631534362664960</ref>.

;Sequential AACIs
The '''Sequential AACIs''' were the AACIs introduced with the implementation of [[Johnston]], allowing to a single ship to roll multiple AACI IDs at once, greatly increasing the trigger rate. Since the [[Game Updates/2023/May 26th|26/05/2023]] update, this mechanic is defunct, being available to all ships.
*''See [[Sequential AACI|here]] for more details.

=Stage 3 - Airstrike=
Planes that participate in this phase:
* {{Seaplane}} Reconnaissance Seaplanes
* {{Carrier Recon}} Carrier-based Reconnaissance Aircraft
* {{Torpedo Bomber}}{{Dive Bomber}}{{JetFighterBomber2}} Carrier-based Bombers
* {{Seaplane}} Seaplane Bombers
* {{ASWPlane}} [[Liaison Aircraft]] with {{Dive}} Dive Bombing stat.
With both preliminary phases executed, the final Aerial Combat Stage, Airstrike, is performed. In this phase, each bomber from the Allied Fleet and Enemy Fleet that still possess a slot size higher than 0 selects a ship to attack. The attack target is randomly picked following the same rules as [[Shelling]] target selection. The targeted ship is '''not necessarily''' the ship that has defended against said bomber during Stage 2.
See [[Damage_Calculations#Airstrike|Damage Calculations]] for details on airstrike damage.
* To start, each bomber slot is randomly assigned to an opposing ship that will perform the defense.
;Notes
* Each bomber is assigned to a single ship and performs exactly one attack. The same ship may be selected to be attacked by multiple different bombers.
* The attack is unaffected by the battle's Engagement and the Fleet's Formation, as well as the Carrier's morale and damage state.
* Submarines are untargetable by Airstrike
** This only applies for active player fleet.
* Abyssals have their own anti-air formulas that are weaker than the ship girl ones. Please see [[Anti-Air_Fire#Abyssal_Anti-Air|Abyssal Anti-Air]] for details.
=Airstrike=
==Contact==
[[file:Contact.png|thumb|right|Tenzan Model 12 (Murata Squadron) performing Contact against the Enemy Fleet.]]
Contact is a special mechanic that increases the damage of '''all bombers''' participating in the Airstrike Phase. Specifically, it may be triggered during Stage 1, but has no effects until Stage 3. When successful, the Squadron performing Contact will be shown on top of the opposing fleet's "Radar", together with the text '''Making contact!''' (触接中!, ''shokusetsu-chū!'').
* Contact may be triggered only under {{color|green|'''AS+'''}}, {{color|green|'''AS'''}}, and {{color|red|'''AD'''}}. It '''cannot''' trigger under '''AP''' and {{color|red|'''AI'''}}.
* At least one {{Carrier Recon}} [[Carrier Recon]], {{Torpedo Bomber}}/{{Night Torpedo Bomber}} [[Torpedo Bomber]], {{SPR}}/{{Night Recon}} [[SPR|Seaplane Recon]], or {{LFB}} [[Large Flying Boat]] must be present.
** {{SPB}} [[SPB|Seaplane Bombers]] '''cannot''' perform contact.
'''Important Notes'''
===Step 1: Contact Trigger===
This step determines if any contact can trigger at all. Each plane that can perform Contact '''except''' {{Torpedo Bomber}}/{{Night Torpedo Bomber}} [[Torpedo Bomber|Torpedo Bombers]] contributes an independent trigger rate based on the plane's {{LOS}} LoS stat and slot size. The Final Trigger Rate is determined using the sum of all independent trigger rates, and is also affected by Air State.
* If only {{Torpedo Bomber}}/{{Night Torpedo Bomber}} [[Torpedo Bomber|Torpedo Bombers]] are present, there is still a very small chance Contact Trigger can succeed.
* The accuracy of the airstrike is fixed at around 95%.

A single roll is performed using the Final Trigger Rate. If successful, Contact advances to Step 2.
===Step 2: Aircraft Selection===
After a successful Step 1, each plane will roll a Selection rate to be allowed to perform contact. The rolls are performed for each plane independently following a set priority, from highest to lowest. The priority for Aircraft Selection is:
* <math>\text{AA}_{adjusted}</math> is the adjusted AA of the ship. For information on how it is calculated, please see [[Anti-Air Fire#Adjusted Anti-Air|Anti-Air Fire]].
* {{Acc}} Accuracy stat, starting from highest.
* <math>\text{Luck}</math> is the ship's {{Luck}} stat.
* The Carrier's position in the fleet, starting from Flagship.
* The Equipment slot position, starting from the first.
* <math>\text{Mod}_\text{Ise-class}</math> is the [[:Category:Ise Class|Ise-class]] bonus of <math>25</math>.

'''Important Notes'''
The first Squadron that succeeds to be selected will perform Contact. If all planes fail to be selected, '''Contact will not trigger''', even if Step 1 was successful.
If successful, then Contact will grant an additional damage multiplier based on the selected aircraft's {{Acc}} stat.

==Anti-Air Rocket Barrage==
Certain ship types have the ability to trigger an "Anti-Air Rocket Barrage" (AARB), completely negating any airstrike damage.
* The '''only''' ships types able to trigger this mechanic are:
** [[BBV]], [[CV]], [[CVB]], [[CVL]], [[CAV]], and [[AV]].
* The ship must be equipped with a '''{{Equipment/Link|12cm 30-tube Rocket Launcher Kai Ni}}'''.
** It is often referred to as "RLK2" or "Rosa Kai Ni" for short.
{{Formula
|Title=AARB Trigger Rate Formula
|Math=\text{AARB %} = 100 \times \frac{\text{AdjAA}_\text{ship} + {0.9} \times \text{Luck} }{400 - \left( 40 \times \text{N}_\text{rocket} + \text{AdjAA}_\text{RLK2} + 30 + \text{Mod}_\text{Ise-class} \right)}

}}
[[File:Anti-Air Rocket Barrage.png|thumb|right|Ise triggers AARB, while Choukai triggers a AA Shell barrage, during the Airstrike Stage.]]
If the AARB triggers on a ship, the ship will slide forward, and '''Rocket Barrage Successful''' (噴進弾幕成功, ''funshindan maku seikō'') will be displayed over its card.
*If the ship does not take any damage during the airstrike, the same animation will also be played, even if the AARB failed to trigger or the ship was not targeted by any bomber.
*Generally when a ship is targeted by any bomber and takes no damage, the text "'''miss'''" will be displayed over the ship's card, but if the AARB actually triggered, nothing will be displayed instead.
;Notes
* It is possible to achieve more than 100 % activation rate.
* There is another anti-air barrage animation in-game for only {{AA Shell}} [[AA Shell]]s. ''No effects were found for it.''
** The combination of a [[AA Shell]]s and the {{Equipment/Link|12cm 30-tube Rocket Launcher Kai Ni|text=RLK2}} is also supposed to have extra effects. ''No effects were found for it.''
** The uselessness/cosmetic-only role of AA Shells in this mechanic might be an historical reference to the real T3 shells, being extremely ineffective in their AA role, and being compared to simple "fireworks".
* [[Smoke]]s reduce the AARB trigger rate, either directly or by reducing the '''Adjusted AA'''.
