Would the Royal Navy have been better off building Renown-type battlecruisers instead of the Revenge-class battleships?
Short answerPerhaps for World War II, but the Revenge class was more useful for the First World War the navy was then fighting.
NotesRenown-type battlecruisers could look more useful when judged against World War II requirements. The Revenge-class battleships were more useful for the First World War. Replacing one with the other therefore changes which conflict the fleet is best equipped to fight.
