German maritime infrastructure had been badly weakened, and rebuilding industrial and design capacity under treaty oversight was difficult. Shipyards, supporting industries, and accumulated design knowledge had been reduced or lost after the First World War. That background explains the difficulty of producing the ships Germany did. Combat effectiveness still depends on what a ship can withstand and accomplish in its assigned role. Wartime opponents do not adjust for an enemy's industrial disadvantages, so protection, firepower, and survivability remain the relevant standards.

German shipbuilding constraints and combat effectiveness
Postwar loss of yards and maritime capacity helps explain Germany's design constraints. Combat effectiveness still depends on the mission a ship must perform.
