Plan Z runs into industrial limits

Where would Germany obtain the capacity and experience to build the huge ships imagined under Plan Z?

It would need a much larger shipbuilding industry, new facilities, and trained workers, which could not be created on the proposed timetable.

Germany lacked the maritime infrastructure to build the enormous battleships imagined in these plans. New dry docks and yards would require a trained workforce, while the army and Luftwaffe competed for the resources needed to create that capacity. Foreign construction offered no credible shortcut because the powers with suitable facilities were unlikely to build such a fleet for Germany. The comparison with China's carrier programme illustrates the difference between a decades-long industrial expansion and the roughly six years envisaged for Germany.
