It is the ESAD standard fighter carrier. I made a couple of concepts but this seemed the best.
There is no fancy deployment like in Battlestar Galactica, they just exit trough the hangar-bay airlocks on each side. Each hangar bay can contain up to 8 fighters on both sides. That is a total of 288 fighters always ready for instant deployment.
