I suspect Hitech would have to rewrite the rebuild function for strat like objects which the CV acts like one. Since we don't loose fighter hangers, fuel, ord or troops. And in real life when your CV got hit, it left the battle as soon as feasibly possible for a repair depot. Our CV in it's own simple way is functioning like real life, even better than real life, since the deck stays open for air operations until the ship is sunk.
