Ship building facilities

I'll admit, I haven't played very many games, and those were small ones just to try and get a feel for it. I'm actually waiting til release to see what the missing 4X features will be comprised of... Anyways, the few that I have played I've noticed that I only had the two intial ship building facilities (for capital ships and light frigate ships)... Is this the way the game plays out always, or do you eventually get the abilitiy to build more ship building facilities at other locations? Sorry it's such a n00b question, but alas, that's me.. the Sins n00b...
