Of higher priority than a second model for CV's are cargo ships. This is primarily for scenarios, but I'd also like them to have a supply function in the game similar to the fuel tanks/ammo bunkers/barracks for land bases. I.e. sinking the ammo ship that's with the fleet would have the same effect on planes launching from the fleet as killing the ammo bunker at a base would have for planes launching from that base.
After cargo ships (Liberty freighters and tankers, I hope), I'd like to see an honest-to-gosh battleship. To go along with that, I'd like to see a real damage model for ships, such that you could disable/destroy selective systems on a ship, such as radar, individual guns, etc.
