Aircraft
The Montana-class would have used aircraft for reconnaissance and for gunnery spotting. The type of aircraft used would have depended on when exactly the battleships would have been commissioned, but in all probability they would have used either the Kingfisher or the Seahawk. The aircraft would have been floatplanes launched from catapults on the ship's fantail. They would have landed on the water and taxied to the stern of the ship to be lifted by a crane back to the catapult.
