To say that Germany had made preparations that would astonish their rival powers on the global stage would be the most severe understatement of the century. After extensive testing and trial by error, the Type XXI U-Boat was finally launched.
Or should I say it was an improved variation of the world's first submarine designed to primarily operate underwater? The first of the months following the completion of the mechanical computerized targeting system, which was arguably the hardest part of the U-Boat to develop.
With the submarine's hull being manufactured via pre-fabricated sections, Bruno had managed to streamline the process to where it took a mere 90 days on average to fully commission a single U-Boat. And considering his shipyards in Danzig and Hamburg were capable of producing multiple submarines at once, this meant that every three months, the German Navy received a dozen or so U-Boats per shipyard.
