The video challenges Plan Z's assumption that rival navies would leave their force structures unchanged while Germany built a huge surface fleet and submarine arm. At full scale the plan projected 797 ships by 1948, including 249 U-boats. Britain was already ordering Flower-class corvettes before the war and could build many more escorts while Germany expanded its submarine programme. France and the United States likewise possessed industries and naval plans that would react to visible German construction. Building hundreds of ships would also make technical upgrades harder because each change had to be introduced across a larger, less uniform fleet. A bigger fleet therefore increased both the enemy response and Germany's own infrastructure burden.

Plan Z and the Allied industrial response
A projected 797-ship German fleet could not be assessed in isolation because Britain, France, and the United States would expand escorts and other forces in response.
