Well, they update the CV's, but with the new graphics engine maybe something is in store.
to take it a step further, have it so that when a CV takes damage, it can be repaired in some way.. dropping CV supplies from a goon or something.. I.E. the cv takess damage and starts to list.. if left alone it will eventually capsize, but if x number of goons drop CV supplies, "damage control" will repair the damage and the boat will survive.
trying to sneak a goon in to resupply the fleet during combat would probably be a pretty hair raising ride..
