I see multiples of the pirate carrier for sale in the black market of almost every decently-sized system, which is probably not good. I've yet to see it in an actual fleet, though.
You may also want to do a stat balance pass on the ships eventually. There's a lot of problems all over the place here; one of the most obvious examples is the drone carrier, which is only 4 logistics (the minimum baseline for a one-deck carrier, essentially) but has a PD drone system better than the Astral's, competent flux stats, and 90 speed. The other really obvious ones are the base freighter, which at 500 cargo cap/logistics is more efficient than an Atlas (~300), and the tug, which only uses 0.6 (!!!) fuel/ly.
