Sort of a light carrier, or maybe an all-in-one System Control Ship, eh? I LOVE this idea. It sort of reminds me of the old Imperial Grand Cruisers from BFG; large-ish vessels that were capable of serving as the nucleus of a small independent force.
I'm wondering if the battlecruiser might be a better stat line to start with? Maybe not in terms of weapns, but DR 5/CR 8/Mv 8"/HP 6/CP 7/AP 4/PD 4, with 2 shields, strikes me as a better fit. Plus, you could make it 1-2 for a squadron instead of 2-3. Weapons wise, I think it would be OK to start with the heavy cruisers, but add a torpedo array perhaps? I would think a price of around 120 would probably be about right to start with, plus wings.
