What if Imperial Germany's pre-1914 naval industrial capacity reappeared alongside the Kriegsmarine's existing capacity in 1936?
Short answerGermany could build more and heavier ships, but Britain would respond with orders that preserved shipyard capacity and intensified the naval arms race.
NotesThe restored infrastructure gives Germany more ways to build ships and heavy guns, including an established 15-inch weapon tradition. Much of the inherited equipment and design thinking remains rooted in the First World War. Germany also has little time to turn the added capacity into completed ships. Britain would recognize the reappearance of infrastructure that Versailles had tried to suppress while naval negotiations were breaking down. British yards facing closure could receive orders before restrictive covenants were imposed. Palmer and Beardmore are named as examples of the lost capacity, while the last prewar covenant is dated in the discussion to June 1939. The distinction matters to the scenario: orders in 1936-37 could prevent further closures and restrictions before they took effect. The result becomes a race to expand production, with Britain able to draw on an ongoing design program.
