Questions on fleet ships:
1) Can fleet modules be obtained in any other way other than purchase for zen or EC on the exchange?
2) Do you need a ship token (space) for your fleet ship like any other ship, and if you do, can you delete a lower level ship to make room for that slot?
1) I guess someone could give you one but otherwise no.
2) You need a space for your ship for any ship you obtain whether it is a fleet ship, lock box ship, or one you buy off the C-Store. Yes you can delete lower level ships to free up their slots, make sure you pull anything you want to save off them first though as it will destroy the equipment when you delete them.
