A nine-gun American 18-inch battleship

How might an effective American 18-inch-gun battleship have been designed?

He would scale up an Iowa-like design for nine 18-inch guns, matching American layout preferences while respecting the space demanded by the larger weapons.

The six-gun Georgia concept appears less representative of American capital-ship preferences. A more likely alternative is a scaled-up Iowa-style battleship carrying nine 18-inch guns. That choice fits the United States Navy's established comfort with nine-gun heavy-cruiser and battleship layouts. The later continuation adds that a larger calibre makes ten- or twelve-gun arrangements increasingly difficult because turret and hull space impose sharper penalties.
