Get all Betty bombers up in the air with bombs and 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 to make them lose their air power. After the carrier is done, take out the destroyers. Then, have one air field take out the two battleships. Use torpedoes on the battleships.
