Would it be possibly that it could be a new Carrier that carries the Fighter & bomber? 

1 weapon slot

1 Engine Slot

2 -4 Armor slots

And I don't know perheps 6 -8 slots for fighter & Bomber?

And also the ship design should be unique for every Faction.. Also Every faction may not see Fighter & Bomber tactic as a tactic so they may not build the Carrier.
