Why was Vanguard's bridge such a leap compared with King George V or rebuilt Queen Elizabeth-class ships?
Short answerIt reflected wartime experience, Lion design influence, and the realization that battleships would often serve as command assets.
NotesVanguard's bridge looks more advanced because the design absorbed wartime lessons and elements from the Lion design path. By that point, a battleship was less likely to serve only as a line-of-battle gun platform. Shore bombardment and fleet action both demanded improved control spaces. Command duties placed additional weight on communication and coordination.
