Naval Combat would be sweet.
Carriers- mobile spawn points for Libs, Reavers and Mosquitos
Submarines- Torpedos and perhaps slow fireing cruise missles
Destroyers or Frigates- ASW and small shore bombardment batteries
Battleships- Naval/moblie versions of the Flail
Gunboats- Small and fast and mounting 20mm recoiless cannons and perhaps a mortor laucher
Tenders- Naval nano supply for the rest of the "fleet" which allows repawning of aircraft or replenishment of ammunition used.
