How long would war need to be delayed for the Normandie class to enter service, and what would the ships change?
Short answerA delay to roughly 1918 could bring them into service, but by then the Anglo-Russian relationship might be fraying and their value could shift from fighting Germany to deterring former partners.
NotesThe Normandies likely require peace until about 1918 to join the fleet. By that date Britain may regard the German naval challenge as contained, while Russian pressure toward India could strain or break the Triple Entente. The ships would still strengthen France against the Central Powers, but their longer-term strategic value might lie in a less stable postwar alignment.
