Yea, the drones one my ship are just a little extra too (if it was a specialized carrier the number would be in the thousands).I could never taint my girl by strapping hideous drone racks to her hull. I don't mind though, I mean she's not suppose to be a drone carrier. If I REALLY wanted to I could convert the main hangar into drone bays which would give me an even greater capacity than you have, but then I wouldn't know how to launch the things from an interior space and I wouldn't have anywhere to dock normal ships.
Just little something to emphasize the "Better start running now, boy" effect on enemies.
