#Areas that have support expeditions available for use have support expeditions listed under the expedition tab for the corresponding area. For a list of support expeditions, please [[Support_Expedition#Expedition_List|see below]].
+
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 sortie fleet must encounter an eligible node '''before the support expedition timer runs out''' in order for support to appear.
+
**Node support
−
#* If the timer runs out, 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'''.
+
*[[Events]]:
−
#* 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.
 
−
#* 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]]
−
==Shelling Support==
+
===Steps===
−
This is the most commonly used support expedition. It is just a shelling attack against the whole enemy fleet.
+
#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===
 +
{{Details|Nodes}}
 +
* 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 supports:
 +
** Airstrike support,
 +
** ASW support,
 +
* Torpedo support,
 +
 
 +

 +
* The {{FCF}} {{Equipment/Link|Fleet Communication Antenna|Communication Equipment & Personnel|text=Communication equipment}} give a bonus '''only''' when equipped on the '''first or second ship''' of the support fleet.
 +
** All related bonuses are unclear yet.
 +
* The flagship affects the trigger rate disproportionately.
 +
** Always place a sparkled ship as flagship.
 +
* The maximum chance for node support to trigger with no communication equipment is '''91 %''' and the lowest is '''51 %'''.
 +
**With {{FCF}} communication equipment, it can reach ~96 %
 +
** 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.
 +
** 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===
 +
{{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]] is ignored,
 +
** For ASW support only, the ASW [[Visible Fit Bonuses]] are also 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.
 +
 
 +
===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]] do not 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.

−
* It costs the most out of all the support types.
+
The attack works similarly to the [[shelling]] phase.

* Try to aim for 147 displayed firepower on battleships to meet the parallel cap (184 for head-on).
+
|-|Airstrike Support=
−
* For carriers, 52 displayed firepower is needed to meet the parallel cap with a single 10{{Dive}} plane (77 for head-on).
+
The attack will go through the normal [[Aerial Combat]] phases.
−
** It is 39 for parallel and 64 for head-on with two 10{{Dive}} planes.
+
* 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'''.

==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.

** 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.
 
−
* 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.

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.

Overview

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.

A shelling Support Expedition appears in a night battle node

Steps

  1. Deploy the support fleet in the expedition menu,
  2. Send another fleet in sortie,
  3. 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

For more information on this topic, see Nodes.
  • 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 supports:
    • Airstrike support,
    • ASW support,
  • Torpedo support,

Trigger Rate

The trigger rate differs between node support and boss support.

Trigger Rate Formula
The base trigger rate for each support is as follow:
[math]\displaystyle{ \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} }[/math]
With
  • [math]\displaystyle{ \text{Mod}_\text{flag} }[/math] being 15 if the flagship is sparkled .
  • [math]\displaystyle{ \text{N}_\text{escort} }[/math] the number of non-flagship sparkled ships.

The following is still under investigation, being approximative

When a Command Facility Fleet Communication AntennaFleet Communication Antenna (FCA) is used, a second trigger roll will be held if the 1st one failed:

[math]\displaystyle{ \text{2nd Roll %} = 5 + 5 \times \text{N} + \text{Mod}_\text{CEP} + 2 \times \bigstar }[/math]
With
  • [math]\displaystyle{ \text{N} }[/math] the number of sparkled ships,
  • [math]\displaystyle{ \text{Mod}_\text{CEP} }[/math] being 20 when using a Command Facility CEPCommunication Equipment & Personnel,
  • [math]\displaystyle{ \bigstar }[/math] the Improved improvement level of the Command Facility FCAFleet Communication Antenna.

[1]

Notes
  • The Command Facility Communication equipmentFleet Communication Antenna
    Communication Equipment & Personnel     give a bonus only when equipped on the first or second ship of the support fleet.
    • All related bonuses are unclear yet.
  • The flagship affects the trigger rate disproportionately.
    • Always place a sparkled ship as flagship.
  • The maximum chance for node support to trigger with no communication equipment is 91 % and the lowest is 51 %.
    • With Command Facility communication equipment, it can reach ~96 %
    • 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.
    • 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

For more information on this topic, see Damage Calculations.

Supports use slightly different formulas than regular shelling attacks.

  • Only visible stats are taken into account,
  • 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.

Accuracy

For more information on this topic, see Accuracy.

As a consequence, contrary to the rest of the battle, here the accuracy needs to be balanced with the attack power.

Fleet composition

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)
    • Note that using 3BBV will trigger Aerial Support. To avoid Aerial Support, use at least one (F)BB.
Ship should be chosen based on firepowerFirepower, level and luckLuck.

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.

Meet all of the following requirements:

  • At least 1CVL present.
  • At least 1 additional CVL/AV/AO/LHA/CL/CT or 2DE
Recommended Composition
  • 2DD, 2CVL, 2CV(B)
Carriers should only be chosen based on plane slots.

Notes

The attack works similarly to the shelling phase.

  • This support cost huge amount of fuelFuel and ammoAmmunition

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 Card Provisional Resupply.png Provisional Resupply will not resupply aircraft.

  • 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.
Bug
  • The Item Card Provisional Resupply.png Provisional Resupply will not resupply aircraft.

Equipment Setups

Any eligible ship type not mentioned in this table is subpar not recommended for use in support. The order of the equipment is for illustrative purposes only. Can be placed in any order.

It is not recommended to run airstrike support with more than 1 fighter because it is better to run shelling support when encountering that much enemy airpower.

Bombers should be placed in the largest slots.

Long Range Torpedo Support

It is the cheapest support but also by far the weakest. In addition, there is a bug that massively reduced the accuracy of this support[1].

Trigger Requirements
  • Do not meet any of the requirements for shelling, airstrike, or ASW support.
Notes
  • Do not bother using this type of support, since it is by design inferior to the previously mentioned ones.


FAQ

Q: Why didn't my support show up?

A: Double check that you have:

  1. Sent the support to the right area.
  2. Sparkled a sufficient number of ships.
  3. Have the correct composition for support to appear.
  4. You resupplied the fleet before sending them off.

If all those are checked, it was just bad luck.


Q: I used 4BBV, why didn't support show up?

A: Because that triggers airstrike support. If you had no seaplane bombers, that causes airstrike support to fail.


Q: Does support work in night battle nodes?

A: Yes, but only shelling support.


Q: Which support should I use?

A: Generally shelling. Airstrike and ASW support only have niche uses.


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.


Q: Why is my morale going down so fast?

A: Node support costs 1-5 morale and boss support costs 1-10.


Q: Can I try torpedo support?

A: No.
