Expeditions

Unlocking Expeditions

You must complete Quest A4 (Have 1 light cruiser as your flagship, 6 ships total in your fleet) to unlock expedition mode. Usually, completing an expedition will unlock the next one in numerical order, but there are some expeditions which will also unlock others.

• Clearing Expedition 5 unlocks Expedition 9.
• Clearing Expedition 18 unlocks Expeditions 22, 25 and 33.
• Clearing Expedition 20 unlocks Expedition 27.
• Clearing Expedition 26 unlocks Expeditions 34 and 35.

Unlocking Expedition 30 and 31 for Quests D5 to D8: Clear 1-5, 9-20, 27-29

Unlocking Expeditions 37 to 39 for Quests D9, 11, 13, 14: Clear 1-5, 9-18, 25-26, 35-36

Unlocking Expedition 23 for Quests D10 and D12: Clear 1-5, 9-18, 22

Notes

• You must meet the minimum flagship level, fleet size and combination requirement as specified in the conditions section in order to complete the expedition.
• After meeting the fleet composition requirements, you may add ships as you please. This can be useful to meet flagship level or combined fleet level requirements.
• You will not be able to use your main fleet for any expeditions. Only Fleets 2-4 can be used for expeditions.
• If all ships have 50 or higher morale (i.e. they are sparkling), then it is possible to achieve great success, which grants 50% more resources, double the experience, and great success item reward if applicable. 
  

  Great Success
  • Chance of great success increases approximately 16% per sparkled ship.
  • Sufficiently high morale can persist for multiple expeditions; see the Morale/Fatigue for tips on how to sparkle effectively.
  • It can be useful to assign or prepare ships for expedition duties.  You can consider low consumption ships as mentioned below and/or ships you sparkle ahead of time to be ready for expedition duties.

• Expeditions that require ships with Drum Canister equipped have a chance of great success without sparkling (50% chance with 0 sparkling ships).  This can be combined with sparkling a few ships to increase chances of great success.
• Remodeled DDs (other than Verniy) have the same fuel/ammo consumption as before remodel. Remodeling and modernizing your DDs makes getting high morale for them much easier.
• Mutsuki class and Tenryuu class (unremodeled) have the lowest consumption for DD/CL.  They can save a lot of resources when used in highly draining expedtions that deplete most of your ammo.  Maruyu (unremodeled) is the lowest consumption ship in the game.  SS have the lowest fuel consumption and can be great for expeditions as well.
• Expeditions will automatically complete if you enter the main screen with less than a minute remaining on the timer.
• Always resupply before embarking on an expedition otherwise you will likely fail.
• For expeditions that give one type of item (Devkit/Bucket/etc), you have a 50% chance of getting it.
  • For ones 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 if you achieve great success, and low reward chance with normal success.
• Equipping ships with a Large Utility Boat (comes with Akitsu Maru after large ship construction) adds a 5% resource gather bonus, which is stackable as more boats are equipped (e.g. 2 equipped boats result in a 10% bonus) up to a maximum of 20% (4 utility boats).
  • This is calculated multiplicatively with the great success 50% bonus, so each utility boat gives a 7.5% increase when great success is achieved. 
• While the amount of Admiral EXP gained is significantly reduced to 30% upon failing an expedition, the amount of Ship EXP gained remains unaffected.

Support Expeditions

Support expeditions involve sending a fleet into an expedition, which will then provide additional bombardment during the first phase. For the November 2013 event and Spring 2014, there were two support expeditions (109/117 and 110/118), and for more veteran admirals, expeditions 33 and 34. You will need to successfully finish expedition 18 to unlock expedition 33, and expedition 26 to unlock expedition 34. Currently, expeditions 33 and 34 work only in world 5.

Note that support expeditions do not work for night battle nodes!

There are two major differences between 109/33/117/125 and 110/34/118/126:

• 109/33/117/125 supports you in general node battles, the amount of battles they help with seems to be random. The activation rate of non-boss support expeditions for all nodes/battles is higher (close to 100%) if you sparkle the first two ships (or more) in the expedition fleet. See this video for an example.
• 110/34/118/126 however is for support in the BOSS NODE ONLY. This is generally the one you go for, and is more or less guaranteed to happen. Note: there have been player reports where it is not 100% activation in event maps (E-6). Consider sparkling ship(s) to increase activation rate and/or damage.

To start a support expedition, you will need to bring a minimum of two DDs (Destroyers) with the other 4 slots comprised of whatever you like, however the composition will affect what type of firepower support is provided.

1. Aerial Support

Sends a number of planes to carry out bombardment and torpedo attacks.

• Condition: 3 or more CV, CVL or seaplane tenders.
• Resources: Bauxite and 4 units of Ammunition

Advantages:

• Damage is spread out, and likely to hit the flagship (good for events)
• Low cost since the only bauxite needed is for planes which were shot down by enemy AA.

Disadvantages:

• Spread out damage is unlikely to sink any particular ship.
• Planes sent are affected by enemy AA, so will be less effective against high AA enemy fleets.

2. Long distance Torpedo Attack

High miss chance and low damage. Currently, no practical use (stated in wikiwiki). Damage is lower than even normal torpedo attacks.

• Condition: At least 4CL, CLT or DD. And has total Torpedo stats above 250.
• Resources: 4 units of Ammunition

3. Support Shelling

If none of the aforementioned conditions are met, support fleet will use their main guns to shell the enemies. Damage depends on Artillery stats. CVs and CVL are counted slightly differently, and use the following formula to calculate their firepower. (Referenced from wikiwiki)

55 + (1.5 × artillery) + (1.5 × torpedo) x slots + (2.0 × divebomb) x slots

e.g. Kaga Kai with 4 slots of Suisei 12A Divebombers:

55 + (1.5 x 49) + (1.5 x 0) x 4 + (2.0 x 10) x 4 = 208, i.e. Kaga will effectively have 208 firepower.

Hence it is advisable to go 2DD 2CV 2BB for the strongest firepower (any more CVs/CVLs will change it to aerial support). CVLs have great cost-performance ratio here (no. of planes don't count, only slots).

• Condition: Not meeting any of the two conditions above.
• Resources: 8 units of Ammunition

Advantages:

• High damage if hit, and likely to sink an enemy ship or badly damage it.

Disadvantages:

• High cost, even if the support wasn't activated during sortie.

Support expeditions will end if either of these two conditions are fulfilled:

1. You finish a sortie.
2. The timer runs out.

Please make sure you run the sortie you wish to do the moment you start the expedition!
