Hitler's Lost Submarine - Episodes One & Two

In 1991, U.S. professional diver John Chatterton descended to a dangerously low level of 230 feet to what he thought was an old barge. What he found instead was a German U-boat with torpedoes and bodies of its crew intact, lying a mere 60 miles off the coast of New Jersey. Follow his quest to discover how the sub got there, why it sank, and what the exact role of subs was in World War II. In a pursuit across the globe for answers that takes over six years and costs three lives, Chatterton comes up with startling information and coincidences.

Search For The I-52 Submarine
This documentary takes viewers on an ocean expedition to find a sunken World War II Japanese submarine and to recover its precious cargo. Meet expedition leader Paul Tidwell, who spent nine years gathering information to locate the sub's whereabouts, three miles below the ocean surface. Watch the deep-sea submersibles, made famous in the movie Titanic, as they catch the first glimpse of the vessel that sank over 50 years ago. Submarine I-52's doomed journey and secret mission is retold through historical footage and interviews with veterans credited with sinking the ship all those years ago

Submarines, Secrets and Spies
For the 40 years of the Cold War, submarines prowled the seas, but only a select few knew of their triumphs and tragedies. Using recently declassified material, the veil is lifted on several tragic and mysterious submarine accidents and some high-risk missions that helped determine the outcome of the war. Join underwater explorer and National Geographic Explorer-in-Residence Robert Ballard as he recounts how he found the U.S. Navy's Thresher, the most advanced nuclear sub of its day, that sank during a test, taking 129 sailors to their graves. Learn about the multimillion-dollar CIA mission to recover a sunken Soviet sub and its secrets off the ocean floor, and other tales of intrigue and tragedy.

Raising of the U534
Off the coast of Norway on May 5, 1945, with World War II all but over, a British Royal Air Force plane, a RAF Liberator, sank a German U-boat, the U534. The sub's crew didn't know its cargo, but rumors were rife: a hoard of gold, stolen and looted art treasures, perhaps even Hitler's mistress, Eva Braun, herself. During the attack, the ship's crew managed to scramble to safety just as the damaged but mostly intact hull of the U534 slipped down into one of the deepest crevices of the freezing sea. After 50 years underwater, and in almost impossible salvage conditions, the U534 reveals its secrets as leading salvage experts raise the wreck and find out what the ship carried in its hold.
