Expedition

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. Unlocking Expedition 30 and 31 for Quests D5 to D8: Clear 1-5, 9-20, 27-29
 * 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.
 * Clearing Expedition 1-8 unlocks Expedition 32.

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

Conditions

 * You can use light carrier (CVL), seaplane tender (AV) instead of standard carrier (CV) for carrier expeditions. However, if the requirement stated that it's needed specific type of carrier, such as CVL or AV, the other type won't count.
 * You can use Aviation SS (SSV) for submarine (SS) expeditions, unless stated otherwise below.
 * Aviation CA (remodeled Mogami-class and Tone-class) will NOT be counted as CA for requirement.
 * Torpedo CL (remodeled Ooi, Kitakami and Kiso) and Traning CL (Katori) will NOT be counted as CL for requirement.
 * Aviation BB (remodeled Ise-class and Fusou-class) will NOT be counted as BB for requirement. Likewise, normal BB class (Kongou-class, Nagato-class, Bismarck-class and Yamato-class) cannot finish an expedition that requires BBV (Aviation BB).
 * To obtain Drum Canister you've to clear quest F11 and F12 or craft equipment.
 * Please see the Glossary for additional information on letter abbreviations.
 * Any ship can be the flagship as long as it's initial requirement of ship composition, level and combined level is achieved (e.g. Expedition 30 you can put 1 DD lvl 60 as flagship and 4 other DDs). Expedition 32 (which required Katori as flagship) is the only one excluded from this rule.

Theoretical Hourly Net Earnings
Best possible income using ships with the lowest resource consumption possible.

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 is for support at the standard nodes with roughly 50% chance to trigger, it can trigger on every node you go through (except the boss) even if it already triggered once. Sparkling slightly raises the chances of it triggering (~5% per ship?)
 * 110/34/118/126 is for support at the boss node with ~80% chance to trigger, appears to be 100% if the flagship is sparkled.

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 the ship's firepower. CVs and CVL are counted slightly differently, and use the following formula to calculate their firepower. (Referenced from wikiwiki)
 * 55 + (1.5 × firepower) + (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: Please make sure you run the sortie you wish to do the moment you start the expedition!
 * 1) You finish a sortie.
 * 2) The timer runs out.
