Your comment on the difficulty in completing Jean Bart brings up the point of restocking ammunition and big propulsion replacement parts. What elements could be done in North Africa? Or, would the French be forced to sideline some vessels and cannibalize them just for parts and ammunition stores? Though, don't some munitions have relatively short "shelf life" in hot climates?Richelieu shouldn't take that much effort to complete especially since she won't be damaged via a gun duel and air raids. Jean Bart on the other hand is a lost cause as far as completion during the war unless her second turret and the guns for if(and ideally some spares) magically appear in the UK
If cannibilizing some ships isn't sufficient, do they replace with US or British gear, as the large size factories are still operating in those spots?
