On certain maps, it is possible to call "support expeditions" to help the fleet during battles. These expeditions are deployed like normal resource expeditions and have a chance of appearing at certain nodes or at the boss.
*Currently, these are only available in [[World 5]] and [[Events]].
Currently these are only available in World 5 and events.

===Expedition List===
Areas that have support expeditions available for use have support expeditions listed under the expedition tab for the corresponding area:
*[[World 5]]:
**Node support
**Boss support
*[[Events]]:
**Node support
**Boss support
It behaves differently than other expeditions:
*Instead of the normal 3 morale reduction for normal expeditions, the morale loss from support expeditions varies:
** Node support: 1-5
** Boss support: 1-10
*The resource cost is '''rounded up''' instead of down.

[[File:Support_Expedition.png|thumb|right|A shelling Support Expedition appears in a night battle node]]
===Steps===
#Deploy the support fleet in the expedition menu,
#Send another fleet in sortie,
#The support expedition will come back automatically once the sortie ends, even if she did not show up.
Support expeditions will always consume resources, '''regardless of whether they have performed a support attack'''.
===Node===
* Node support: 1-5
{{Details|Nodes}}
* Boss support: 1-10
* Nose support may appear on most battle nodes. But not on boss nodes.
** Note that only aerial support can appear on Submarine Nodes or Airstrike Supported Battle.
** Note that aerial support cannot appear during [[night battle]].
* Boss support can appear only on boss nodes.
===Support type===
There are 4 types of support which are determined by the fleet composition:
* Shelling support,
* Aerial support,
** Airstrike support,
** ASW Support,
* Torpedo support,
===Trigger Rate===
===Trigger Rate===
The trigger rate differs between node support and boss support.
The trigger rate differs between node support and boss support.
{{Formula
|Title=Trigger Rate Formula
|Math=\begin{align}
\text{Node %} &= 51 + \text{Mod}_\text{flag} + 5 \times \text{N}_\text{escort} \\
\text{Boss %} &= 86 + \text{Mod}_\text{flag} + 5 \times \text{N}_\text{escort}
\end{align}
|Var=<math>\text{Mod}_\text{flag}</math> is the '''sparkled flagship bonus''' of <math>15</math>.
* <math>\text{N}_\text{escort}</math> is the '''Number of non-flagship sparkled ships'''.
}}
* <math>\text{Mod}_\text{consort}</math> is the '''sparkled ship bonus''' of <math>5</math> for every other ship in the fleet.
;Notes
* The flagship affects the trigger rate disproportionately.
** Always place a sparkled ship as flagship.
* The flagship affects trigger rate disproportionately.
** Always place a sparkled ship as the flagship if you do not have the time to sparkle the rest of the fleet.
* The maximum chance for node support to trigger is '''91%''' and the lowest is '''51%'''.
* The maximum chance for node support to trigger is '''91%''' and the lowest is '''51%'''.
** It is recommended that you sparkle all the ships for node support in order to get the maximum trigger chance.
** It is recommended to sparkle all the ships for node support in order to get the maximum trigger chance.
* Boss support can reach '''100%''' trigger chance with only the flagship sparkled.
* Boss support can reach '''100%''' trigger chance with only the flagship sparkled.
** It is recommended that you at least sparkle the four heavy hitters in order to maximise accuracy.
** It is recommended to at least sparkle the four heavy hitters in order to maximize accuracy.
==Attack Specification==
The support fleet will appear between the [[Aerial Combat]] and the [[Battle Opening]] phase during day battles.
* The exception is night-day nodes where airstrike/ASW support arrives after [[LBAS]] but before [[Aerial Combat]],
* The ships attack random targets in the fleet order.
** To maximize the [[Scratch Damage]], the weakest ships (usually DD) should be placed first.
===Damage===
{| width=100%
{{Details|Damage Calculations}}
Supports use slightly different formulas than regular shelling attacks.
* Only '''visible stats''' are taken into account,
** This means [[Hidden Fit Bonuses]] and [[Improvement]] bonuses are ignored,
** [[Plane Proficiency]] are ignored.
* The damage cap for supports is '''170''' in all cases,
** This means that even if a support shows up in night battle, it does not get the advantage of the 360 damage cap,
* The only modifier are the [[engagement]] and the [[formation]], even in night battles,
* Misses are also displayed on ships that are not 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.
This is the most commonly used support expedition. It is just a shelling attack against the whole enemy fleet.
===Accuracy===
{{Details|Accuracy}}
* Only '''base stats''' are taken into account.
** This means [[Hidden Fit Bonuses]] and [[Improvement]] bonuses are ignored.
** unlike damage Accuracy [[Visible Fit Bonuses]] doesn't work.
* The only modifier are the [[morale]] and the [[formation]].
'''As a consequence, contrary to the rest of the battle, here the accuracy needs to be balanced with the attack power.
===Fleet composition===
<tabber>
|-|Shelling Support=
Meet '''all''' of the following requirements:
* 2 or more (F)BB(V) '''OR''' 4 CA(V),
* No more than 1 CV(B/L)/AV/LHA.
;Recommended Composition
* 2DD, 3(F)BB(V), 1CV(B)
* 1 or more FBB/BB/BBV/CA/CAV in the fleet.
** Note that using 3BBV will trigger Aerial Support. To avoid Aerial Support, use at least one (F)BB.
* Not more than 1 CVL/CV/CVB/AV/LHA.
Ship should be chosen based on '''firepower'''{{firepower}}, '''level''' and '''luck'''{{Luck}}.
'''Recommended Composition'''
|-|Airstrike Support=
* 3BB1CV2DD
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)
Ship should only be chosen based on plane slots.
|-|ASW Support=
Meet '''all''' of the following requirements:
* At least 1CVL present.
* Basic attack power is calculated in the same way as normal for [[Damage_Calculations#Surface_Shelling|surface ships]] and [[Damage_Calculations#Carrier Attacks|carriers]] except that '''firepower is reduced by 1'''.
* At least 1 additional CVL/AV/AO/LHA/CL/CT or 2DE
* [[Hayasui]] uses the surface shelling formula instead of the carrier attack formula for support even when equipped with torpedo bombers.
;Recommended Composition
* 2DD, 2CVL, 2CV(B)
Carriers should only be chosen based on plane slots.
</tabber>
;Notes
<tabber>
|-|Shelling Support=
The attack works similarly to the [[shelling]] phase.
*This support cost huge amount of fuel{{Fuel}} and ammo{{Ammo}}
|-|Airstrike Support=
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.
** But the required fighter power for obtaining air control is reduced by planes lost in earlier air control phases.
* Airstrike support '''costs bauxite {{bauxite}}''' on top of the normal resupply costs because lost planes need to be resupplied.
* Taking [[jets]] on airstrike support still costs steel {{steel}} but does not trigger a jet assault phase.
* Ships that cannot launch bombers '''will not participate in airstrike support'''.
;Bug
*The {{Item/Icon|Provisional Resupply|size=50px}} Provisional Resupply will not resupply aircraft.
'''Equipment Setups'''
|-|ASW Support=
* All planes with an ASW stat will participate in support.
** Fighters, Carrier Recons, and Jets are excluded.
** 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.
** However the [[Damage_Calculations#Anti-Submarine_Warfare|armor penetration]] mechanic from [[Depth Charge]]s still works.{{cite}}
;Bug
*The {{Item/Icon|Provisional Resupply|size=50px}} Provisional Resupply will not resupply aircraft.

'''Q: Why isn't XX composition listed as recommended?
'''A:''' Because it is subpar and not worth your time. You're generally running support if there are tough things en-route that you need taken out. There's no point in cheaping out and increasing the randomness of the outcome.
'''Q: Can I use XX ship with more guns/dive bombers for shelling instead?
'''A:''' It is advisable not to use ships that require too many guns or dive bombers to take to the parallel or head-on cap. Support requires all the accuracy it can muster to be effective.
'''Q: Do I really have to sparkle everyone?
'''A:''' You should have at least 4 ships sparkled for node support and the flagship sparkled for boss support. It is still recommended to sparkle the 4 heavy hitters for boss support because sparkling helps accuracy.
