Expeditions

Introduction

Expeditions button in your sortie screen

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.

• Resources accumulated from expeditions can go beyond the resource soft cap.
• Expeditions provide exp.

Menu Functions

• Expedition List - Displays all the expeditions you have unlocked.
• Resources Yield - Displays the resources that can be earned from that expedition.
  • A rough indication of the magnitude of resources earned can be found on the right under the resource cost.
• Sample Composition - Displays the minimum required composition to succeed in that expedition.
• Resource Cost - Displays the vague fuel and ammunition cost of the expedition. It is displayed as either:
  • None (なし)
  • Little (少量)
  • Normal (普通)
• Confirm - Allows you to select an expedition and brings up the fleet selection menu.
• Begin Expedition - Allows you to send the selected fleet on an expedition.

The Dot System

On each expedition, the amount of resources earned are displayed with 0 to 4 dots, 0 meaning that the resource is not found on the expedition, and each additional dot approximately show the resources generated with the following rule :

	0 dot	1 dot	2 dots	3 dots	4 dots
resource range	0	1-240	240-480	500-650	750-2000

• Those values do not take great success or the use of DLC or drums into account.

In those cases, the limits of the ranges are inclusive, so for instance, an expedition giving 240 resources can have either 1 or 2 dots, for no apparent reason.

This dot system being very approximate, you may refer to the Reference Tables.

Unlocking Expeditions

The Expedition menu is locked at the start. You will need to complete Quest A4 to unlock it.

Expedition Page of World 5. The number 3 marker denotes the third fleet is on this expedition

Normally, completing an expedition will unlock the next one in numerical order. The exceptions are:

• Expedition 5 unlocks Expedition 9.
• Expedition 18 unlocks Expeditions 22, 25 and 33.
• Expedition 20 unlocks Expedition 27.
• Expeditions 1 through 8 unlock Expedition 32.
• Expedition 26 unlocks Expeditions 34 and 35.
• Expedition 8 and A1 unlocks Expedition A2.
• Expedition 24 and A2 unlocks Expedition A3.
• Expedition B1 unlocks Expedition 41.
• Expedition A4 and 41 unlocks Expedition 44.
• Expedition A4 and B4 unlocks Expedition B6.
• Expedition 32 unlocks 45 and D1.

Certain expeditions also require clearing maps in addition to completeing other expeditions:

• Clearing 1-5, Expedition 9-20 and 27-29 unlocks Expedition 30 and 31 (for Quests D5, D6, D7 and D8).
• Clearing 1-5, Expedition 9-18, 25, 35 and 36 unlocks Expeditions 37, 38, 39 (for Quests D9, 11, 13 and 14).
• Clearing 1-5, Expedition 9-18 and 22 unlocks Expedition 23 (for Quests D10 and D12).

Performing Expeditions

Dispatching Fleets

Sending a fleet on expedition

To dispatch fleets on an expedition:

1. Select the expedition you wish to do from the expedition menu.
2. Click the Confirm (決定) button to bring up the fleet selection menu.
3. Select the fleet you wish to dispatch using the fleet icons at the top.

• Remember that the first fleet cannot be dispatched.
  

4. Click on Begin Expedition! (遠征開始！) to dispatch the fleet.

Important Notes

• Up to 3 fleets can be dispatched at once.
  • They cannot be dispatched on the same expedition.
  • Please see Composition on how to unlock more fleets.
• Every expedition has specific success conditions. Please 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 Expeditions.
• Damage state does not affect success or failure.
  • Heavily damaged (大破) flagships will render the fleet unable to be dispatched.

Recalling Expeditions

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.

• Cancelled expeditions do not yield any resources or experience.
• They are counted as failures on your Admiral profile.
• A recall cannot be cancelled'.
• Support expeditions cannot be recalled.
• Recalled fleets do not return immediately, the return time is calculated as:

[math]\displaystyle{ \text{Return Time} = \frac{\text{Time}_\text{min}}{3} }[/math]

Where, [math]\displaystyle{ \text{Time}_\text{min} }[/math] is the lesser of remaining time' or elapsed time.

For example, a fleet is sent on expedition #1 (15 minutes), then after 6 minutes, it is recalled.

1. The remaining time is 9 minutes.
2. The elapsed time is 6 minutes.
3. The smaller number of the two, 6 minutes elapsed time in this case, is divided by 3.
4. The final recall time is 2 minutes.

Success Conditions

Normal Success

Meeting the requirements for the expeditions as 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.

• Supply status: Fleets should be fully resupplied before being dispatched. Fleets without enough supplies to meet the expedition cost will fail.
• Flagship level: The flagship must have a level greater or equal to the required flagship level of the expedition.
• Fleet level: Certain expeditions also have a sum total of fleet level requirement that must be met.
• Composition: Certain expeditions require certain ship types and/or certain numbers of ship girls to be dispatched.
• Drum Canisters: Certain expeditions such as 21 require a certain number of Drum Canisters to be equipped by the fleet.
• Stats: Certain expeditions such as A2 have certain sum total of fleet stat requirements that must be met. Required stats can be firepower , Torpedo , ASW , Line of Sight or Anti-Air .

Great Success

A Great Success (GS) (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 conditions, great success requires either:

• Sparkling: Ship girls with 50 or more 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%.
  • Even with 6 sparkled girls, these expeditions still have a chance to not have a GS. The minimum requirement to guarantee GS is to "over drum" the fleet and sparkle at least 4 girls.
  • The following are the "over drum" requirements:
    • 21 - 4 drums on 3 girls
    • 24 - 4 drums on 1 girl
    • 37 - 5 drums on 3 girls
    • 38 - 10 drums on 4 girls
    • 40 - 4 drums on 1 girl
    • 44 - 8 drums on 3 girls
    • E2 - 6? drums on 3 girls

• Level: Certain expeditions have an innate great success chance related to flagship level.
  • Using a higher levelled flagship will increase the base great success chance of those expeditions.
  • The formula for determining the GS chance is as follows:

[math]\displaystyle{ \text{GS%} = 16 + ( 15 \times \text{No. Sparkled} ) + (\sqrt{\text{Flag Lvl}} + \frac{\text{Flag Lvl}}{10}) }[/math]

• • • The base GS rate with a level 175 flag and no sparkled ships is 46%.
    • A level 128 flag with 4 sparkled ships has a 100% GS rate.
    • A level 33 flag with 5 sparkled ships has a 100% GS rate.
  • The following expeditions are those affected by the "flagship level" rule.
    • World 1 - A2, A3, A4, A5, A6
    • World 2 - B3, B4, B5, B6
    • World 7 - 41, 43, 45
    • World 4 - 32, D1, D2, D3
    • World 5 - E1

Expedition Rewards

Expeditions will always yield primary resources () upon success. Secondary rewards are not guaranteed.

Expedition 12 gives medium box (left) and development material (right)

• Items listed on the left always have a 50% chance of being obtained regardless of normal or great success.
• Items listed on the right are guaranteed on a great success and have a very low chance on a normal success.

See below for a summary:

Result	Resources	Experience		Rewards
		HQ XP	Ship XP	Left	Right
Recall	None	None	None	None	None
Failure		x0.3	x1 or x2 (50% chance)
Normal Success	x1	x1	x1 or x2 (50% chance)	50%
Great Success	x1.5	x2	x2 or x4 (50% chance)	50%	Guaranteed

Notes

• Flagships get 1.5x exp modifier as per usual
• If the right reward can give more than 1 item, it will be a random quantity between 1 and its maximum possible. (Eg. If right reward is 3 buckets, it can be 1-3 buckets randomly)
• As of Phase 2 rewards are not ordered in Left/Right format, and the terminology is kept only for reference to expedition tables within the wiki.

		B88	Type 2 Seaplane Fighter Kai		Seaplane Fighters are important, you want up to 8 of them. Type 2 Seaplane Fighter Kai can be can be converted from Type 0 Reconnaissance Seaplane. This gives you an easy quick one and saves time & screws. PBY-5A Catalina is a LBAS range extender which is useful and important, though just a worse version of Type 2 Large Flying Boat. However PBY-5A Catalina is currently only obtainable from here and may not be obtainable at all in the future. No obvious choice here but I lean on recommending picking PBY-5A Catalina and then making at least two Type 2 Seaplane Fighter Kai through Akashi.
			PBY-5A Catalina
		B89Less important quest	Improved Kanhon Type Turbine		The boiler and its better version are stock equipment of many ships. For some, Turbines may be harder to come by. However both are for increasing the speed of ships though. Both craftable development.
