I see the resemblance between the turrets. Also, a PD turret larger than the fighters it\'s going to be swatting? You sure about that? Seems more like an anti-frigate weapon, considering it\'s about the same size as a frigate.
I\'m trying to keep the same style for the ship, glad you noticed. As for the size of the turrets, it\'s for protection agains things that could qualify as treaths (like frigates). I don\'t even think that fighters could crack the shield regen. The titan will also carry multiple fighter sized drones for offensive and deffensive purposes.
