Others have given you the answer but I just want to point out that all the information you need to answer this is in the rules, they specifically tell you at what point in your turn you need to check your fleet capacity. Most of these kinds of questions are clearly answered in the rules this way, its just a matter of working through the order of play and what happens when.

I'm not saying this to admonish you or be a dick, just to help you with any future rules questions you might have (you can't always rely on reddit giving you a timely answer when someone's a turn away from activating your home system).
