How did turbine production constrain Plan Z?
Short answerGermany was already struggling to supply turbines for existing capital ships, so new yards alone would not enable the larger programme.
NotesAdditional dry docks and building slips would not solve every obstacle to Plan Z. Germany also needed enough manufacturing capacity to supply ships' turbines. Engine production and installation were already delaying Bismarck, Tirpitz, and Graf Zeppelin, so expanding the fleet required more than providing places to assemble hulls.
