Get all Betty bombers up in the air with bombs. Send them all to the same place. Turn their C.A.P. on, or they will not get close to the target. When all your bombers reach a place before the ships, send them all in on the carrier making them lose their air power. After the carrier is done, go after the destroyers. Then have one air field go after the two battleships. Use torpedoes on the battleships as they are more effective.
