German submarine output suffered under divided authority

How did Germany respond to the Allies building more escort warships?

It needed more submarines, but production improved slowly because control first sat under Göring's Four Year Plan apparatus and only later moved to Speer.

The obvious response to a rising Allied escort force was to build more U-boats, but German production authority was fragmented. Submarine construction sat under Hermann Göring's Office of the Four Year Plan rather than straightforward naval control. Output began to improve after responsibility moved to Albert Speer, although the change took time. Bureaucratic organization constrained an otherwise clear force-structure response.
