Question about fleets

Hey all,

       So I finally recieved the game, and am playing through my first round. First off this game is awesome, if not a little daunting. there is so much to take into account when your playing its almost overwhelming, I'm sure I'll get used to it the more I play. Anyway a quick question, first of many I'm sure

How do I raise my logistics to make bigger fleets?

I have all these ships and its kinda a pain in the arse to move them one by one or three by three as it is, Im sure its an easy fix but like i said there so much going on so I must be missing something.

thanks in advance
