Areas that have support expeditions available for use have support expeditions listed under the expedition tab for the corresponding area:
#The type of support fleet that appears depends on the composition of the fleet. Please see the [[Support_Expedition#Support_Types|various support types]] for more details.
+
*[[World 5]]:
#The a sortie must be started '''before the support expedition fleet returns to port''' in order for support to appear.
+
**Node support
#* If the expedition fleet has returned to port, support fleets will not appear.
+
**Boss support
#Shelling and torpedo support can '''appear in night or day nodes''' but airstrike and ASW support can '''only appear in day nodes'''.
+
*[[Event]]:
#* No support will appear in air raids, air battles, or radar ambush nodes.
+
**Node support
#The support fleet will appear after the [[Aerial Combat]] phase during day battles.
+
**Boss support
#* The exception are night-day nodes where airstrike/ASW support arrives after [[LBAS]] but before [[Aerial Combat]].
  −
#The damage cap for support is '''170''' for all cases.
  −
#* This means that even if support shows up in night battle, it does not get advantage of the 360 damage cap.
  −
#* The cap during '''head-on engagement''' is 212.
  −
#Only '''visible stats''' are taken into account.
  −
#* This means any hidden modifiers from upgrades or gun fit are ignored.
  −
#When the sortie fleet returns, the support fleets will return as well.
  −
#* They will return regardless of if they have performed any support attacks.
  −
#* The timer must be waited to expire like normal expeditions.
  −
#Support expeditions will always require resupplying '''regardless of if they have performed a support attack'''.
  −
#Instead of the normal 3 morale reduction for normal expeditions, the cost for support expeditions vary.

===Damage===
 +
{{Details|Damage Calculations}}
 +
The support use slightly different formula than the counter part
 +
*Only '''visible stats''' are taken into account.

*The damage cap for support is '''170''' for all cases.
 +
* This means that even if support shows up in night battle, it does not get advantage of the 360 damage cap.
 +
*The only modifier are the [[engagement]] and the [[formation]].
 +
* Misses are also displayed on ships that aren't targeted.
 +
 
 +
* [[AO]] use the surface shelling formula instead of the carrier attack formula for support even when equipped with torpedo bombers.
 +
** Enemy ships sunk in earlier combat phases '''are still counted''' towards contesting air control for airstrike support.

{{Details|Accuracy}}
 +
*Only '''base stats''' are taken into account.
 +
** This means [[Hidden fit bonus]] and [[improvement bonus]] are ignored.

;Notes
 
;Notes
* Shelling support deals the highest damage among all support types.
+
<tabber>
** It is the most likely to sink enemy ships.
+
|-|Shelling Support=
* It costs the most out of all the support types.
+
 
** This is due to the requirements for battleships and heavy cruisers.
+
 
** Costs can be controlled by using cheaper battleships and light carriers but '''it is not recommended to use heavy cruisers'''.
+
|-|Airstrike Support=
* Try to aim for 166 displayed firepower on battleships to meet the parallel cap (209 for head-on).
+
* The attack will go through the normal [[Aerial Combat]] phases.
* For carriers, 52 displayed firepower is needed to meet the parallel cap with a single 10{{Dive}} plane (77 for head-on).
+
** This means that damage can be reduced by plane losses through the air control and anti-air fire phases.
** It is 39 for parallel and 64 for head-on with two 10{{Dive}} planes.
+
** Planes in airstrike support appear to have some shoot-down resistance that helps them survive anti-air fire.
 +
*** But the required fighter power for obtaining air control is reduced by planes lost in earlier air control phases.
 +
* Airstrike support '''costs bauxite''' on top of the normal resupply costs because lost planes need to be resupplied.
 +
* Taking jets on airstrike support still costs steel but does not trigger a jet assault phase.
 +
* Ships that cannot launch bombers '''will not participate in airstrike support'''.
 +
 
 +
|-|ASW Support=
 +
* All planes with an ASW stat will participate in support.
 +
** Fighters, Carrier Recons, and Jets are exluded.
 +
** They will not even contribute to determining air control, but they will not be shot down.
 +
** Seaplane fighters and fighter bombers will participate.
 +
* Although DDs and DEs are included in the fleet, they '''do not participate''' since it is a variant of airstrike support.
 +
* It only takes into account '''plane ASW''', equipping sonars and depth charges will be a waste.

==Airstrike Support==
+
|-|Airstrike Support=
Airstrike support functions much like a normal airstrike with a few major differences as detailed below.
+
'''Bombers should be placed in the largest slots'''.
 
  −
;Trigger Requirements
  −
Meet '''one''' of the following requirements:
  −
* At least 2 or more CV(B/L)/AV/LHA in the fleet,
  −
* 1 or more CV(B/L)/AV/LHA and no (F)BB(V)/CA/CAV,
  −
* 2 or more BBV/CAV/AV/LHA/AO and no (F)BB/CA.
  −
 
  −
;Recommended Composition
  −
* 2DD, 4CV(B/L)
  −
 
  −
;Details
  −
* Every plane slot targets a random enemy ship.
  −
** This gives airstrike support up to 16 chances to hit.
  −
* The attack will go through the normal [[Aerial Combat]] phases.
  −
** This means that damage can be reduced by plane losses through the air control and anti-air fire phases.
  −
** Planes in airstrike support appear to have some shoot-down resistance that helps them survive anti-air fire.
  −
** Enemy ships sunk in earlier combat phases '''are still counted''' towards contesting air control for airstrike support.
  −
*** But the required fighter power for obtaining air control is reduced by planes lost in earlier air control phases.
  −
* Airstrike support '''costs bauxite''' on top of the normal resupply costs because lost planes need to be resupplied.
  −
* Taking jets on airstrike support still costs steel but does not trigger a jet assault phase.
  −
* Ships that cannot launch bombers '''will not participate in airstrike support'''.
  −
* Though the standard cost of airstrike support is 40% ammo, this only applies if '''there are 3 or more CVL/CV/CVB/AV''' in the fleet. Support will cost 80% ammo otherwise.
  −
* Only visible stats are considered for airstrike support.
  −
** This means all bonuses from upgrades or plane proficiency are ignored.
  −
* Damage is calculated slightly differently compared to normal airstrikes. Please see [[Damage_Calculations#Airstrike|airstrike damage]] for details on the variables used.
  −
 
  −
 
  −
<math>\text{Airstrike Support} = \biggl\lfloor \biggl\{ \text{Type} \times \bigl( \left( \text{DB or TP} \right) \times \sqrt{\text{Count}_\text{Plane}} + 3 \bigr) \biggr\} \times \text{Mod}_\text{crit} \biggr\rfloor \times 1.35</math>
  −
* The [[Damage_Calculations#Damage_Formula|damage cap]] of 170 is applied to the result between <math>\{ \ \}</math>.
  −
* <math>\text{Type}</math> is the bomber's type modifier, similar to airstrikes.
  −
** <math>1.0</math> for dive bombers and seaplane bombers.
  −
** Either <math>0.8</math> or <math>1.5</math> for torpedo bombers.
  −
* The critical modifier and the 1.35x airstrike support modifier are both '''post-cap'''.
  −
 
  −
* Like airstrikes, damage is unaffected by formation or engagement.
  −
* The accuracy appears to be lower than normal airstrikes.
  −
* It does not appear in night battle nodes.
  −
** But does appear in night-day nodes once the battle shifts to day.
  −
 
  −
;Notes
  −
* This support is useful for dealing with multiple lightly armored ships or for racking up chip damage on high HP, high armor enemies.
  −
* Because it follows after LBAS and regular airstrikes, carriers can bring more bombers due to the reduced air control requirements.
  −
* It is one of the cheapest supports to run as long as 3 or more carriers are used.
  −
* Since slot size matters for damage, the carriers with the largest slots should be used to maximize damage.
  −
* Due to damage being calculated off remaining planes, airstrike support can be reduced '''the more nodes it appears in''' due to plane losses.
  −

==Anti-Submarine Support==
+
|-|ASW Support=
Anti-Submarine support functions exactly like [[Support Expedition#Airstrike Support|airstrike support]]. Everything about airstrike support applies to ASW support with a few key differences. 
+
'''Bombers should be placed in the largest slots'''.
 
  −
;Trigger Requirements
  −
* At least 1CVL present. 
  −
* At least 1 additional CVL/AV/AO/LHA/CL/CT or 2DE
  −
 
  −
;Recommended Composition
  −
* 2DD, 2CVL, 2CV(B)
  −
 
  −
;Details
  −
* All planes with an ASW stat will participate in support.
  −
** Fighters, Carrier Recons, and Jets are exluded.
  −
** They will not even contribute to determining air control, but they will not be shot down.
  −
** Seaplane fighters and fighter bombers will participate.
  −
* Although DDs and DEs are included in the fleet, they '''do not participate''' since it is a variant of airstrike support.
  −
* If it encounters a mixed surface/sub fleet, only submarines will be attacked.
  −
** It will still attack surface fleets with airstrike support if equipped with bombers.
  −
* It only takes into account '''plane ASW''', equipping sonars and depth charges will be a waste.
  −
** However the [[Damage_Calculations#Anti-Submarine_Warfare|armor penetration]] mechanic from [[Depth Charge]]s still works.{{cite}}
  −
* Damage is calculated slightly differently to airstrike support:
  −
 
  −
<math>\text{ASW Support} = \biggl\lfloor \biggl\{ \bigl(\text{ASW} \times \sqrt{\text{Count}_\text{Plane}} + 3 \bigr) \times \left(0.9 + \text{Rand} \right) \biggr\} \times \text{Mod}_\text{crit} \biggr\rfloor \times 1.35</math>
  −
* The [[Damage_Calculations#Damage_Formula|damage cap]] of 170 is applied to the result between <math>\{ \ \}</math>.
  −
* <math>\text{Rand}</math> is a random number from 0 to 0.75 inclusive.
  −
* The critical modifier and the 1.35x airstrike support modifier are both '''post-cap'''.
  −
 
  −
;Notes
  −
* Because slot size matters, carriers make much better ASW support ships than light carriers.
  −
* It has a chance of triggering at every node so consider the enemy compositions of all nodes when running ASW support to help with submarine nodes.
  −
** A full ASW support setup that runs into enemy airpower will get destroyed.
  −
* Because even the autogyros and liaison aircraft participate in aerial combat, they can be shot down.
  −
* It can be useful for chipping down submarines to reduce the number of opening and closing torpedoes faced by the fleet.
