Unlocking Expeditions
You must complete Quest A4 (Have 1 light cruiser as your flagship, 6 ships total in your fleet) to unlock expedition mode. Each expedition will become available as soon as the previous expedition is successfully completed.

Conditions

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, there were two support expeditions (109 and 110), 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, only expeditions 33 and 34 work in world 5.

There are two major differences between 109/33 and 110/34: 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.
 * 109/33 supports you in general node battles, the amount of battles they help with seems to be random.
 * 110/34 however is for support in the BOSS NODE ONLY. This is generally the one you go for.


 * 1. Aerial Support
 * Sends a number of planes to carry out bombardment and torpedo attacks


 * Condition: 3 or more CV, CVL or amphibious plane tender.
 * Resources: Bauxite and 4 units of Ammunition


 * 2. Long distance Torpedo Attack
 * High miss chance and High damage. Damage depends on torpedo stats


 * Condition: At least 4CL, CLT or DD. And has total Torpedo stats above 250.

 * 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

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!
