a new ship a airship! more like a hover carrier it would move at the same speed as the uss beast but would be air borne and due to it being a supposed airship it would add a excellent airborne runway and also a great target it could have about 4 gun emplacements to make it challenging but a basic design would be this example:http://i1106.photobucket.com/albums/h367/MonasinghX/Carrier.jpg
