Right now you can afford a gunstar as your starting ship (since it costs 20 Defense).  By spending 20 power, you can buy a second (smaller) fleet, which I want you guys to do for Muse and PiP's characters (plus I've wanted a second carrier).<br/><br/>If you raise your Defense to 30 you can start with a middle of the road battlestar.  Once your "flagship" is chosen it can not be changed, really.  You can upgrade it a little to be more effective, but it can't suddenly become a different type of ship.
