How many 5-inch Mark 12 guns, 40 mm Bofors, and 20 mm Oerlikons could an Iowa-class battleship carry?
Short answerA great many, but ammunition storage would set the practical limit.
NotesThe battleship has enough size and deck area to carry a large light and medium anti-aircraft battery. Counting mounts alone, however, hides the space required for magazines and ready-use ammunition. Every additional weapon also needs a sustainable supply during combat rather than merely a position on deck. The practical gun count is therefore set by the logistical systems behind the armament.
