based on a review from yesterday it was Stated 3 Fleets can be placed per planet. so with that info you technically have 60 Pop Cap For ships per planet if you hve the galactic population to handle it. However, that is assuming that a fleet can only have 20 pop units... While this is a reasonable assumption, it might not actually be correct. The recent FAQ says while there is a 20 pop cap in space, you can call in reinforcements during the battle. I'm not sure about how hyperspace in EAW works, but in the SW universe ships have different travel speeds. Which means fleets have different travel speeds. Seeing as how movement is 'drag and drop' and the game is supposed to be real time, I think coordinating three fleets to arrive at a system at the same time might be hard. So it's also reasonable to assume that a fleet can have a much larger amount of ships and the three fleet spots would be there for when you want to completely seperate fleets... Like for when you have one fleet which is only stopping by and plans to be moved and another which is a permanent garrison.
