What would an F3-style all-forward layout change on a North Carolina-class battleship of the same tonnage?
Short answerIt could marginally improve armor efficiency and speed, but the conventional layout helped the ships blend into the existing battle line rather than stand out as priority targets.
NotesConcentrating the main battery forward could shorten the armored citadel and release weight for slightly broader protection or speed. Those improvements would be marginal. The historical arrangement also had a tactical virtue: North Carolina fitted the visual pattern of the U.S. battle line, whereas distinctive ships such as Nelson and Rodney were easier for an enemy to identify and prioritize.
