You see, I don't think this thing should be put on a cruiser. Artillery is used to take out both large groups of infantry (In our case fighters and bombers) and also strong enough to own a tank (Cruisers and maybe Battleships). I think this idea should be used as a support weapon only, meaning its given this one large gun and 2-4 smaller turrets or guns. I say its given a slower speed due to all of the advance equipment and such and make it vulnerable to close fighting.
