Britain had replacement capital ships under construction when it lost Hood, while Germany had far less depth behind Bismarck. The discussion contrasts that British pipeline with the very limited progress on the H39 ships. German yards also had to be rebuilt to accommodate the proposed battleships. Repeated changes to the designs demanded further alterations to those facilities. A construction program could therefore occupy a yard without delivering ships, while making other production harder.

How H39 design changes could obstruct German shipbuilding
Repeated changes to projected German battleships required further yard alterations, tying up facilities while little ship construction advanced.
