Expeditions are the backbone of naval economy. They provide a safe and steady income of virtually all common in-game resources with the exception of [[Akashi's_Improvement_Arsenal|Improvement materials]].
+
The '''Expedition (遠征) menu can be accessed from the '''Sortie (出撃)''' button on the main menu. These will be your main source of all in game resources except for improvement materials {{IM}}.  
*The fuel, ammo, steel and bauxite gained from expeditions can accumulate beyond the [[Tutorial:_FAQ#I_heard_about_the_resource_cap._How_much_is_the_limit.3F_Does_that_mean_I_can.27t_gather_resources_exceeding_my_limit.3F | soft cap]]. This makes expeditions the best way to stockpile resources for events.
  −
*Expeditions also provide [[Experience_and_Rank | experience]], making them useful for levelling up weak ships.
  −
*A few expeditions are sortie [[#Support Expeditions | support expeditions]], which provide additional support fire for difficult sorties and events.
  −
*Many expeditions are also [[Quests | quest requirements]].
     −
Expeditions themselves need to be unlocked first, usually by completing other expeditions or quests. Once they have been unlocked, they can be repeated indefinitely. The list of expeditions does not change from one update to another. However, support expeditions for special event maps might be temporarily included during events.
+
* Resources accumulated from expeditions can go beyond the [[Resources#Soft_Cap|resource soft cap]].

===Dispatching Fleets===
 
[[File:Expedition fleet.png|right|thumb|300px|Sending a fleet on expedition]]
 
[[File:Expedition fleet.png|right|thumb|300px|Sending a fleet on expedition]]
To send fleets on expedition:
+
To dispatch fleets on an expedition:
#Access the Sortie screen and click the rightmost, blue button.
+
1. Select the expedition you wish to do from the expedition menu.  
#Select an expedition.
+
2. Click the '''Confirm (決定)''' button to bring up the fleet selection menu.
#Select a fleet to send on the expedition.
+
3. Select the fleet you wish to dispatch using the fleet icons at the top.
#Click the bottom right button to send the selected fleet on the expedition.
+
** '''Remember that the first fleet cannot be dispatched.'''
 
+
4. Click on '''Begin Expedition! (遠征開始!)''' to dispatch the fleet.
Once unlocked, an expedition can be repeated indefinitely without any penalty to subsequent runs. However, an expedition can only be attempted once at any given moment. Multiple fleets can go on different expeditions, but not the same expedition.
     −
'''The first fleet (main fleet) cannot go on an expedition'''; only the second, third and fourth fleets.
+
'''Important Notes'''
*Quest A4 unlocks the second fleet at the same time as expeditions
+
* Up to 3 fleets can be dispatched at once.
*Quest [[Quests#A14 | A14]] unlocks the third fleet
+
** They cannot be dispatched on the same expedition.
*Quest [[Quests#A16 | A16]] unlocks the fourth fleet.
+
** Please see [[Composition#Menu_Functions|Composition]] on how to unlock more fleets.
 +
* Every expedition has specific success conditions. Please [[#Reference_Tables|see below]] for details.
 +
** Not meeting the conditions will cause the expedition to fail and not yield any resources.
 +
** Fuel and ammunition costs will still be applied.
 +
** Experience will still be gained but HQ experience will be reduced by 30%.
 +
* Expeditions only count for quests '''if the quest is active when the fleet returns'''.
 +
** Therefore you only need to activate the quest when the expedition is nearing completion.
 +
* Expeditions can be completed early by returning to the home screen when less than 1 minute remains on the timer.
 +
* Expeditions cost 3 morale.
 +
** Exceptions are [[Support_Expedition#Overview|Support Expeditions]].
 +
* Damage state does not affect success or failure.
 +
** <span style="color:red;">'''Heavily damaged (大破)'''</span> flagships will render the fleet unable to be dispatched.
   −
Every expedition has its own success conditions. Failure to meet the conditions results in a failed expedition and the fleet will still consume fuel, ammunition and the time specified by the expedition but no resources or reward will be returned. [[Experience and Rank#HQ Experience | HQ XP]] gained from failed expeditions is reduced significantly to 30%, however, [[Experience and Rank#Ship Experience | Ship XP]] gained remains unaffected. While this might prove desirable for those who want to suppress their HQ level, it is generally not recommended due to the resource costs involved.
+
===Recalling Expeditions===
 +
[[File:Expedition_Recall.jpg||border|frame|right|Only seen in an active expedition]]
 +
In the event where you have dispaced the wrong fleet on an expedition or dispatched them to the wrong expedtion, you are able to cancel the expedition by clicking the '''Cancel Expedition/Recall Order (遠征中止/帰還命令)''' button.  
   −
Check the top right corner of the home screen for the bubble indicating an expedition has returned, click on the home screen to view the results of the expedition and obtain any rewards.
+
* Cancelled expeditions do not yield any resources or experience.  
*Expedition quests only count when the expedition fleet returns, therefore, one only needs to activate the quest when the fleet returns.
+
* They are counted as failures on your Admiral profile.  
*Expeditions can be completed earlier by entering the main screen when there is less than one minute remaining in the expedition.
+
* A recall '''cannot be cancelled'.
*Ships lose 3 [[Fatigue and Morale | morale]] per expedition.
+
* Support expeditions '''cannot be recalled''.
 +
* Recalled fleets do not return immediately, the return time is calculated as:
   −
Damage state cannot cause an expedition to fail; however, heavily-damaged ships cannot be deployed as flagships.
+
<math>\text{Return Time} = \frac{\text{Time}_\text{min}}{3}</math>
   −
===Recalling an Expedition===
+
Where, <math>\text{Time}_\text{min}</math> is the lesser of '''remaining time''' or ''elapsed time'''.
[[File:Expedition_Recall.jpg||border|frame|right|Only seen in an active expedition]]In the event where the wrong fleet was accidentally sent on expedition, an "Expedition Recall" is possible to cancel the expedition and save the time otherwise would be wasted on expedition.
  −
 
  −
An expedition cancelled in this manner yields no resources, rewards, or experience. It is also counted as a fail in the Admiral's profile. Fuel, ammunition and morale required by the expedition are still consumed. This should be used with care as '''a recall cannot be cancelled'''.
  −
 
  −
The recalled fleet does not return immediately as it will take a while to return to base. The calculation for return call time is as follows:
  −
 
  −
<div align="center" style="margin:20px;"><span style="border:1px red solid;padding:10px;">''The smaller time between '''remaining time''' and '''elapsed time''' / 3.''</span></div>
      
For example, a fleet is sent on expedition #1 (15 minutes), then after 6 minutes, it is recalled.
 
For example, a fleet is sent on expedition #1 (15 minutes), then after 6 minutes, it is recalled.
Line 70: Line 87:  
#The final recall time is 2 minutes.
 
#The final recall time is 2 minutes.
   −
Note that Expedition Recall '''cannot be used''' if the expedition in question is a [[#Support_Expeditions|support expedition]]. The only way to recall such fleet early is to deploy to a map that corresponds with that support expedition.

=Success Conditions=
 
  −
==Success Conditions==
  −
 
   
===Normal Success===
 
===Normal Success===
Meeting all the following conditions guarantees a ''Normal Success'':
+
Meeting the requirements for the expeditions as [[#Reference Tables|detailed below]] will normally result in a '''Normal Success (成功)'''. Failing to meet the requirements will result in a '''Failure (失敗)'''. Please check your fleets against the following checklist to ensure success.
*'''Fleet's supply'''
  −
**Fleets sent on expedition should be fully [[Tutorial:_How_to_Play#Repair_and_Resupply|resupplied]].
  −
***There are reports of success even when the fleet is not fully resupplied, but it is risky.
  −
 
  −
*'''Flagship's level'''
  −
**The level of the flagship (first ship of a fleet) must be greater than or equal to the ''flagship's level'' specified by the expedition.
  −
 
  −
*'''Total level of fleet'''
  −
**The total level of every ship in the fleet must be greater than or equal to the ''total level of fleet'' specified by the expedition, if any.
  −
 
  −
*'''Ship types'''
  −
**Most expeditions require a certain number of ships of specific types. The ships in a fleet can be in any order but the required number of ships in each type must be met. Some ship types can be used as substitutes for other ship types, some remodelled ship types and their old models are not interchangeable, while other types follow a one-way relationship.
  −
***Light aircraft carriers (CVL) and seaplane tenders (AV) can be used as substitutes for standard aircraft carriers (CV).
  −
***Submarine aircraft carriers (SSV) can be used as substitutes for submarines (SS).
  −
***Aviation cruisers (CAV) and heavy cruisers (CA) are not interchangeable.
  −
***Torpedo cruisers (CLT) and light cruisers (CL) are not interchangeable.
  −
***Battleships (BB) and fast battleships (FBB) cannot be used as substitutes for aviation battleships (BBV).
  −
***Light aircraft carriers (CVL) and standard aircraft carriers (CV) cannot be used as substitutes for seaplane tenders (AV).
  −
 
  −
*'''Number of ships in fleet'''
  −
**Fleets sent on an expedition must contain at least a certain number of ships. After ship type requirements are met, wild card ships (denoted as type XX in the expedition tables) can be added to meet the ''minimum number of ships'' condition. Extra ships beyond the minimum number to help with other conditions are allowed.
  −
 
  −
*'''Number of drum canisters and drum carrying ships'''
  −
**Expedition 21, 37, 38 also require [[Drum Canister]]s to be equipped. The total number of drums and the number of ships carrying drums must be greater than or equal to a minimum value.
     −
{{TipBox
+
* '''Supply status''': Fleets should be fully '''[[Supply (Mechanic)|resupplied]]''' before being dispatched. Fleets without enough supplies to meet the expedition cost will fail.
| tip = The '''[[Drum Canister]]''' is obtainable through quests [[Quests#F11 | F11]], [[Quests#F12 | F12]] and via [[Development#Drum_Canister | development]]. Only destroyers, light cruisers, aviation cruisers, amphibious assault ships, and seaplane tenders can equip drums.

[[File:Greatsuccess.jpg|center|500px|Great Success]]
   −
Great success is an advanced form of success. It grants 50% additional resources, twice the Admiral experience, four times the ship experience and great success item reward if applicable. Great success can be achieved when:
+
A '''Great Success (大成功)''' provides 50% more resources, twice the HQ experience, four times the ship girl experience and the great success reward item (if applicable). In additon to meeting [[#Normal Success | Normal Success]] conditions, great success requires either:
*[[#Normal Success | Normal Success]] conditions are met.
  −
*There are a few great success factor(s):
  −
**Fleets containing ships with 50 morale or higher (i.e. sparkling).
  −
**Expedition requiring [[Drum Canister | Drum Canisters]], as well as expeditions #24 and #40 (if drums are equipped).
  −
 
  −
The chance of achieving ''great success'' increases approximately 16% per sparkled ship. Furthermore, expeditions that require Drum Canisters have a chance to produce ''great success'' independently of morale. These two factors can be stacked so as to achieve Great Success with less sparkling.
  −
 
  −
Please note that success rate increased per sparkled ship for drum canister expeditions is less than expeditions without drum canisters. Exceedingly high number of drums (drum overload) affect the ''great success'' chance of these expeditions.
     −
Damage state is speculated to reduce your chances of great success.
+
* '''Sparkling''': Ship girls with 50 or more [[Morale_and_Fatigue|morale]].
 +
** Each sparkled ship girl increases the great success chance by approximately 16%.
 +
* '''Drum Canisters''': Expeditions which require drum canisters have an innate chance of great success.
 +
** The chance is roughly 50%.
 +
** Drum expeditions can be "over drumed" to increase the great success chance further without needing sparkles.
 +
* '''Stats''': Certain expeditions such as 41 have an innate great success chance related to stats.
 +
** Going over the total stat requirement can increase the chance of great success without needing sparkles.

===Ratings and Rewards===
+
=Expedition Rewards=
Expeditions will always yield the primary resources upon success and they will always grant experience unless recalled. However, secondary item rewards are not guaranteed to be obtained upon success.
+
Expeditions will always yield primary resources ({{Fuel}}{{Ammo}}{{Steel}}{{Bauxite}}) upon success. Secondary rewards are not guaranteed.

[[File:Expedition_Secondary_Reward.jpg|border|frame|right|Expedition 12 gives medium box (left) and development material (right)]]
*For expeditions that give only one type of item, there is 50% chance of getting the item.
+
* Items listed on the left always have a 50% chance of being obtained regardless of normal or great success.
*For expeditions that give two types of items, the item listed on the left of the game screen will have 50% chance. The item on the right will always be rewarded upon ''Great Success'', and has a low reward chance with ''Normal Success''.
+
* Items listed on the right are guaranteed on a great success and have a very low chance on a normal success.
   −
The outcome of expeditions depends on several conditions. There exists four possible outcome ratings; each of which has different resource, experience and item reward yield ratios.

===Landing Crafts===
| tip = The '''[[Daihatsu-class Landing Craft]]''' (LC) is obtainable from [[Akitsu Maru]] and [[Abukuma|Abukuma Kai Ni]] as stock equipment. Each equipped LC will net an additional 5% gain in resources from expeditions, up to 20%.
     −
Total resource gain is multiplied with great success bonus. Combined with great success bonus, the net resource gain is calculated as 50%+7.5% per LC. Thus the max resource bonus is an additional 80% with great success and 4 LC.
+
Equipping certain landing crafts will boost the primary resource gain of the expedition. Aside from the Toku Daihatsu, all other landing craft bonuses stack with each other. All landing craft bonuses are '''multiplicative''' with the great success bonus. This means you can gain 1.8x the resources on great success with four daihatsu in your fleet.
   −
[[Akitsu Maru]] can be constructed in [[Construction#Large Ship Construction|Large Ship Construction]]. [[Abukuma]] can be found through drops or construction and will require a blueprint to become kai ni to obtain her '''[[Daihatsu-class Landing Craft]]'''

|[[Daihatsu-class Landing Craft]]
Support expeditions involve sending a fleet into an expedition to provide additional bombardment during the [[Combat | opening stages of Combat]]. There are two types of support expedition; normal support and boss support:
+
|5%
*Expedition 33 is a normal support expedition (15 minutes). It gives support at every node other than a boss node with ~50% chance to trigger at each node.
+
|20%
*Expedition 34 is a boss support expedition (30 minutes). It gives support at a boss node with ~80% chance to trigger.
+
|Obtainable from: [[Akitsumaru]]{{·}}[[Arare|Arare Kai Ni]]{{·}}[{Ooshio|Ooshio Kai Ni]]{{·}}[[Abukuma|Abukuma Kai Ni]]{{·}}[[Kinu|Kinu Kai Ni]].<br>
Events usually come with their own exclusive support expeditions (e.g. Expedition 133 & 134) that can only be used throughout the event. These event expeditions are unlocked by default.
+
Also obtainable from certain [[Quests|quests]].
 
+
|-
Sparkling your ships (mainly flagship) increases the probability to trigger support while using fatigued ships reduces it. Currently, support expeditions '''''only work in World 5 and events'''''. Since 2017, support expeditions can also trigger in nodes that involve night battles. Support expeditions will end if either of these two conditions are fulfilled:
+
|[[Toku Daihatsu-class Landing Craft]]
#Finish a sortie.
+
|+2% to daihatsu bonus.
#The timer runs out.
+
|+6% to daihatsu bonus.
It is recommended to start a sortie immediately after the support expedition has been sent in order to avoid the timer running out halfway through the sortie.
+
|Obtainable from quests or upgrading basic Daihatsu. For details on how the maximum bonus is calculated, please see the equipment page.

===Support Types===

''The support expedition section has been moved due to length.''

Thus, each attack uses the following formula for damage: <math> \text {Modifier} \times \text {((Bomber's Dive Bomb or Torpedo stat)} \times \sqrt {Number \space of \space Planes} + 3)</math>, where Modifier = 1.0 for dive bombers and either 0.8 or 1.5 (50% chance of either) for torpedo bombers.

#Shelling support does not get the Effective Bonus provided by [[Akashi's Improvement Arsenal|improving equipment]] and uses (Firepower + 5) as attack power instead.

===ASW Support Expedition===

As of 2017, Aerial Support can now trigger at nodes containing enemy submarines, provided that the correct set-ups are used. The requirements<ref>https://twitter.com/muu_1106/status/937539281832230912</ref> are as follows:
  −
#Support Expedition must not meet the requirements for either shelling or torpedo support.
  −
#Support Expedition fleet must contain 2DD + 1CVL + 1"ASW Ship" + any other ships (provided that Rule #1 is not violated).
  −
#*The "ASW Ship" '''must''' be 1 of the following: CVL/AV/AO/CL/CT.
  −
#**This rule is can be bypassed if your fleet contains 2DE, but this is generally not worth the trade-off as all of your damage in an ASW Support Expedition will be derived from slot sizes and the ASW power of said ASW Aviation Patrol equipment (see below).
  −
#*The CVL & "ASW Ship" must have one of the following ASW Aviation Patrol equipment in a slot with a slot size of > 0:
  −
#**Torpedo Bomber/Dive Bomber/Seaplane Bomber/Seaplane Fighter/Seaplane Recon/Taitei/[[Ka-type Observation Autogyro]]/[[Type 3 Spotter/Liaison (ASW)]]
  −
#*Further to the above, the ASW Aviation Patrol equipment must have an {{ASW}} value of > 0.
  −
#**For example, the [[Kyoufuu Kai]] will not count as it does not have an ASW stat.
  −
#**As Fighters are not included in the list, a [[Fulmar]] will not have any effect despite having an ASW stat of 2.

Potential ASW output for the expedition is calculated entirely based on ASW stats of the ASW Aviation Patrol equipment, as well as the respective slot sizes for said equipment. This holds true for even for ships that do not fall into the "ASW Ship" category described above, as long as they they have ASW Aviation Patrol equipment equipped (confirmed for BBV/CAV/CV(B)/Taigei/SSV).
  −
 
  −
Sonars and Depth Charges do not fall into the category of ASW Aviation Patrol equipment. Consequently, equipping these does not have an effect on your support expedition's potential ASW output.
     −
At nodes that do not contain enemy submarines, the ASW Support Expedition will trigger as a standard Aerial Support Expedition instead.

Support expeditions are available in World 5 and events. You can dispatch powerful fleets to help assist you during sorties in those areas. Please see [[Support Expedition]] for more details on what they are and how they work.
