The “39-41-44 problem” comes from reading later wartime fleets backwards and assuming earlier planners should have built exactly the same institutions and equipment. The comparison is especially misleading when the Royal Navy of 1939 and the United States Navy of 1941 are measured against capabilities both had refined by 1944. Geography, likely opponents, treaty-era starting points, and different operational realities shaped what each navy could reasonably prioritize. The rest of the logistics argument follows from that warning.
