Usa Battleship
In this hypothetical development of the Montana-class battleships, the number of 406 mm guns could be increased to sixteen by replacing the three-gun turrets with four-gun ones. While four-gun turrets were initially proposed for battleships of the North Carolina class, they were, however, equipped with 356 mm guns. If the goal were to enhance the firepower of the Montana-class battleships without utilizing a larger caliber, opting for four-gun turrets would be the most logical choice.
