Drain the Oceans - Nazi Secrets
Disney+

Imagine draining the oceans to uncover hidden secrets from World War II. Experts used advanced technology to explore the depths and reveal fascinating stories about Nazi Germany's ambitions and the brave people who fought against them. One story is about the SF Hydro, a ferry that sank in a Norwegian lake while carrying heavy water for the Nazis. Norwegian heroes blew up the ferry to stop the Nazis from getting it. Another tale involves the HMAS Sydney, an Australian warship that disappeared in 1941 after a fierce battle with the disguised German ship Kormoran, which had secret weapons. The Graf Zeppelin, Germany's only aircraft carrier, was raised by the Soviets after the war and used for target practice. Finally, U-480, a German submarine with a special coating that made it invisible to sonar, sank several ships before hitting a British minefield. These stories show how the oceans still hold secrets of the past and the bravery of those who fought for freedom.
