Why Bismarck-class ships begun in 1942 would never finish

When would Bismarck-class ships started in 1942 be completed?

Never, because Germany could not spare the resources to finish them.

Bismarck-class ships laid down in 1942 would not reach completion. Germany could barely find enough resources for the submarines it was already trying to build. New capital ships would demand far more steel, machinery and skilled labour while competing with urgent wartime programmes. Beginning the class that late would create unfinished hulls rather than an operational surface force.
