The German exercise prompts a brief comparison with Imperial Japan. Japan may have had slightly more infrastructure and financial room for naval construction, while the Imperial Japanese Navy stood much higher in its state's procurement hierarchy than the Kriegsmarine did in Germany's. That combination makes a repeated hull fitted either as a capital ship or a carrier institutionally more plausible, although the video does not work through a Japanese production schedule. The aside sharpens the main lesson: standardisation depends on political priority and usable industrial capacity as well as a sound naval design.

Why a common-hull fleet is more plausible for Japan
Japan had more naval priority and slightly more industrial and financial headroom than Germany for repeating one hull as battleships or carriers.
