Operation Deadlight: Where Are the German U-Boats That Disappeared in WW2? In the aftermath of World War II, one of the ocean’s greatest mysteries was born — the disappearance of dozens of German submarines during *Operation Deadlight**. Between November 1945 and February 1946, the Royal Navy carried out a massive mission to scuttle over 100 surrendered **Kriegsmarine U-boats* off the coast of Ireland. But not all went according to plan. Fifty-six submarines vanished before reaching their final destination, lost in violent Atlantic storms, mechanical failure, or something far more mysterious. This documentary-style investigation uncovers what really happened to the U-boats that never made it to the bottom by design. Through declassified naval records, sonar imaging, and underwater expeditions led by maritime archaeologist **Innes McCartney**, we revisit the forgotten graveyard beneath the waves. What McCartney found shocked historians — dozens of intact U-boats resting silently on the seabed, their hulls preserved like underwater tombs. The findings raised new questions: were these submarines really destroyed by weather, or were they deliberately sunk to hide advanced technology and postwar secrets? “**Operation Deadlight: Where Are the Missing German U-Boats of WWII?**” blends authentic history, haunting imagery, and gripping narration to reveal a story of loss, secrecy, and technology buried beneath the Atlantic. Each rusted hull tells a tale of a fading empire, of science and war entangled, and of the silent ocean that became both witness and grave. Dive deep into the mystery of the **lost U-boats**, the secretive Allied operation that erased a fleet, and the underwater discoveries that continue to challenge history itself. The ocean remembers what the world tried to forget. “The events depicted are real and documented. Some dialogues and scenes have been reconstructed from verified historical accounts and sources.”
