Why the Kriegsmarine remains third in line

The common-hull programme sits inside Germany's wider competition for resources. The Army takes precedence because Germany is a continental power, while Hermann Göring's control of the Four Year Plan gives the Luftwaffe another institutional advantage over the Kriegsmarine. Britain reverses that hierarchy: sea and air power protect an island empire, while a smaller mechanised army relies more heavily on mobility and coalition manpower. German naval projects therefore receive only part of the country's apparent industrial capacity, helping explain why even effective U-boat technology did not appear in overwhelming numbers early enough. Allied convoy routing, codebreaking, and signals traffic analysis could exploit that limited submarine force and steer many convoys away from contact. Plan Z remains unattainable because Britain has the yards and funding to begin a post-King George V class before Germany could finish its proposed buildup. Standardisation makes the surface programme more efficient, but it does not move the navy out of third place in the regime's priorities.
