How much weight would three quadruple turrets add to King George V, and might she receive triple 16-inch guns after the war?
Short answerAbout a thousand tons, while a postwar 16-inch conversion would be financially implausible.
NotesThree quadruple turrets would add roughly a thousand tons to the King George V design. The extra mass comes from two more barrels plus ammunition, mechanisms, armor, and structural support high in the ship. Designers would need to compensate elsewhere or accept a larger displacement. A postwar conversion to triple 16-inch guns is dismissed because Britain's financial position after the Second World War was radically worse than after the First.
