Expanding H-class construction capacity

Could improving additional yards allow Germany to build more H-class battleships simultaneously?

Expansion was possible, but it required trained workers, supply-chain capacity and supporting infrastructure, while diverting resources from other construction.

Blohm and Voss took five months to move from launching Bismarck on 14 February 1939 to beginning H on 15 July. Other proposed yards lacked recent experience with warships of comparable size and complexity, while the O-class battlecruisers also needed construction space. Preparing more yards could increase simultaneous H-class starts, but the required workforce and supply chains were not ready for four starts in 1939. Physical improvements alone would leave training and production constraints unresolved. A larger programme remained possible, although the continual design changes made the optimistic timetable unlikely. Assigning a yard and its supporting resources to H-class construction also displaced other work.
