In the quest for world domination, the Nazis built some of the biggest and deadliest pieces of military hardware and malevolent technology in history. With brilliant, dark minds and a legion of captive labor at their disposal, the Nazis believed the path to ultimate victory was to out-build and out-engineer their enemies. To them, bigger definitely meant better, and better meant more lethal. As Hitler's grip on Europe tightened, he ordered men like Wernher von Braun, Ferdinand Porsche and Alfried Krupp to build increasingly outlandish machines and structures to realize his master plan. This is World War II told from a new perspective. This series uncovers the engineering secrets of three iconic mega structures, tells the stories of the evil geniuses that designed them and reveals how these structures sparked a technological revolution that changed warfare forever.
