Mine would be a 3.7km long fleet carrier with similar deployments to the Secutor.
It would be shaped very closely to the Centurion Battlecruiser (picture will be posted at the bottom), with a single massive hangar bay on the bottom, and two hangars at each of its otherwise heavily plated flanks. It would have a large array of maybe 5 Ion Cannon Batteries at the front? With about 20 Light Turbolaser Batteries along the sides of the ship. It would have point defense arrays spread across the topside, and quad lasers defending each of the five hangars. The main weapons would be the 6 Quad Turbolaser Batteries surrounding the bridge, leaving it somewhat defensible at the rear. The bulges? Yeah, those have concussion missile launchers.
It's compliment? 4 Squadrons ARC-170s, 4 Squadrons TIE Defenders, 6 Squadrons TIE Avengers, 1 Wing TIE Interceptors, 1 Wing TIE/ln Starfighters, and 5 Squadrons of TIE Bombers.
