=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.
   −
==Aerial Combat Stages==
+
Aerial Combat has the following structure:
−
{| class="wikitable"
+
#LBAS's [[#Jet Assault Phase|Jet Assault]]
 +
#Fleet's [[#Jet Assault Phase|Jet Assault]]
 +
#[[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.

</center>
+
Planes that participate in this phase:
 +
* {{Template:JetFighterBomber2}},{{Template:JetFighterBomber1}} "Jets" (turbojet propelled fighter-bombers)
   −
* {{GreenPlane}} Fighter planes, and specific {{BluePlane}}{{RedPlane}}{{Seaplane}} Torpedo / Dive / Seaplane bombers with an +AA stat participate in the Fighter Combat.  
+
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]].
−
* Recon planes (carrier based{{YellowPlane}} or seaplane recon{{Seaplane}}) will '''NOT''' participate in Fighter Combat.
+
 
−
* The allied fleet and enemy fleet's Fighter Powers are compared to determine the result of Fighter Combat:
+
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{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.

=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:

* 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:

 +
** {{SPB}} seaplanes.
 +
** {{ASWPlane}} [[Liaison Aircraft]] with {{Dive}} Dive Bombing stat.
 +
 
 +
Following Stage 1, the Fleet AA Defense phase allows each fleet to reduce the incoming Airstrike damage by shooting down enemy planes.
 +
* 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.

[[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
 +
* Grant a multiplier to the "Fixed Shootdown" of all allied ships, referred to as the ''K-value'', regardless of what ship triggers it,
 +
* 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.
 +
 
 +
;AACI triggering
 +
* Only one AACI can be performed per battle,
 +
** On '''"[[Node|Aerial Combat Nodes]]"''', AACI can be triggered twice, one per phase.
 +
* 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>.

−
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 [[Combat#Fleet_Anti-air_Defense|Fleet Anti-air Defense formula]], a general consensus suggests the effectiveness scales with the AA stat ({{AA}}) of the ship triggering it.
+
**The resulting trigger rate is 95.22 %.

;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.
   −
====Requirement====
+
See [[Damage_Calculations#Airstrike|Damage Calculations]] for details on airstrike damage.

+
;Notes
−
:* <u>High-Angle mount</u> (any) {{GreenGunDP}} plus either or both:
+
* 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.
−
::* ''<u>RADAR</u> (any kind)'' {{Radar}}
+
* The attack is unaffected by the battle's Engagement and the Fleet's Formation, as well as the Carrier's morale and damage state.
−
::* ''<u>High-Angle mount</u> (any)'' {{GreenGunDP}}
+
* Submarines are untargetable by Airstrike
−
*[[Maya|Maya Kai 2]] may trigger AACI with a unique setup:
  −
:* [[25mm Triple Autocannon Mount (Concentrated Deployment)|'''<u>25mm Triple Autocannon Mount (Concentrated Deployment)</u>''']], plus <u>High-Angle mount</u> (any) {{GreenGunDP}}
  −

====Notes====
+
==Contact==
−
* [[10cm Twin High-angle Mount + Anti-Aircraft Fire Director|10cm Twin High-angle Mount + AAFD]], [[12.7cm Twin High-angle Mount + Anti-Aircraft Fire Director|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.
+
[[file:Contact.png|thumb|right|Tenzan Model 12 (Murata Squadron) performing Contact against the Enemy Fleet.]]
−
* Slots otherwise empty can be equipped with anything else without disabling the Anti-Air Cut-In.
+
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!'').
−
* 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.
+
* 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'''}}.
−
* Does not affect the determination of [[Combat#Fighter_Combat|Air Superiority]].
+
* 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.
−
* Cannot shoot down pure enemy fighters, as usual.
+
** {{SPB}} [[SPB|Seaplane Bombers]] '''cannot''' perform contact.
 +
 
 +
===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.
 +
 
 +
{{Formula
 +
|Title=Contact Trigger Rate Formula<ref name="vita">[[KanColle Kai]] decompile</ref>
 +
|Math=\text{Contact Rate}= \frac{1 + \sum^{\text{All Planes} } \left( \lfloor \sqrt{\text{Plane}_\text{Count} } \times \text{LoS}_\text{Plane} \rfloor \right)} {\text{Mod}_\text{Air State} }
 +
|Var=<math>\text{All Planes}</math> refer only to all planes that can perform Contact ({{Carrier Recon}}/{{SPR}}/{{Night Recon}}/{{LFB}}) '''except''' Torpedo Bombers ({{Torpedo Bomber}}/{{Night Torpedo Bomber}}).
 +
* <math>\text{Plane}_\text{Count}</math> is the current plane's slot size.
 +
* <math>\text{LoS}_\text{Plane}</math> is the plane's displayed {{LOS}} LoS stat.
 +
* <math>\text{Mod}_\text{Air State}</math> is the Air State modifier.
 +
** {{color|green|'''AS+'''}}: 25
 +
** {{color|green|'''AS'''}}: 40
 +
** {{color|red|'''AD'''}}: 55
 +
}}
 +
 
 +
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:
 +
 
 +
* {{Acc}} Accuracy stat, starting from highest.
 +
* The Carrier's position in the fleet, starting from Flagship.
 +
* The Equipment slot position, starting from the first.
 +
 
 +
{{Formula
 +
|Title=Aircraft Selection Formula<ref name="vita"></ref>
 +
|Math=\text{Selection Rate}= \frac{\text{LoS}_\text{Plane} } {\text{Mod}_\text{Air State} }
 +
|Var=<math>\text{Selection Rate}</math> applies only to planes that can perform Contact ({{Carrier Recon}}/{{Torpedo Bomber}}/{{Night Torpedo Bomber}}/{{SPR}}/{{Night Recon}}/{{LFB}}).
 +
* <math>\text{LoS}_\text{Plane}</math> is the plane's displayed {{LOS}} LoS stat.
 +
* <math>\text{Mod}_\text{Air State}</math> is the Air State modifier.
 +
** {{color|green|'''AS+'''}}: 14
 +
** {{color|green|'''AS'''}}: 16
 +
** {{color|red|'''AD'''}}: 18
 +
}}
 +
 
 +
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.

* Provide an AoE blast on all the incoming enemy '''bombers''', from the ship who is triggering it.'' ([http://kancolle.wikia.com/wiki/User_blog:Reikyu/A_brief_look_at_AA_defense_and_AA_cut-in_performance source 1], [http://kankoregouchin.blog.fc2.com/blog-entry-41.html 2], ''[http://kankoregouchin.blog.fc2.com/blog-entry-43.html 3]'')''

==Anti-Air Rocket Barrage==
−
* '''AA stat''' ({{AA}}) 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 ?  ''([http://kankoregouchin.blog.fc2.com/blog-entry-43.html source 1], [http://kankoregouchin.blog.fc2.com/blog-entry-41.html 2])''

Certain ship types have the ability to trigger an "Anti-Air Rocket Barrage" (AARB), completely negating any airstrike damage.
−
* '''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 ??.'' ([http://kankoregouchin.blog.fc2.com/blog-entry-41.html 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. (''[http://kankoregouchin.blog.fc2.com/blog-entry-43.html source]'')
     −
With an AA Cut-In from a ship with high AA stat ({{AA}}), 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.'''
+
* 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.

There are reports that enemy ships in map [[World_6:_%E4%B8%AD%E9%83%A8%E6%B5%B7%E5%9F%9F#6-2|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===

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.
−
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:
+
*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
−
<math>\text{Shot Down} = \text{Floor((Ship AA } + \text{Floor(Fleet Anti-air} \times \text{Formation Modifier))} \times 0.2125\text{)}</math>, where <br><math>\text{Fleet Anti-air} = \text{Floor(} \sum^\text{All slots}\text{Equipment AA Bonus} \times \text{Equipment Modifier)}</math>
+
* 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 "Fleet Anti-Air" bonus is the sum of every equipment slot of every ship in the fleet (including the defending ship).
+
** 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'''.
