German Admirals Examined A Captured Radar Set — Then Understood Why Their U-Boats Were Vanishing

Video Description

Discover the untold story of how German admirals examined a captured British radar set in February 1943 and realized why their U-boats were vanishing in the Battle of the Atlantic. When a Royal Air Force Stirling bomber crashed near Rotterdam carrying the revolutionary H2S radar system with its cavity magnetron, German scientists at Telefunken headquarters made a devastating discovery. This World War 2 documentary reveals how General Wolfgang Martini and his team uncovered Allied radar technology operating at 9.1 centimeter wavelengths—completely invisible to German Metox detectors. Learn about the Rotterdam Gerät examination, Black May 1943 when 43 U-boats were lost, Admiral Karl Dönitz's withdrawal order on May 24, 1943, and the personal tragedy of Peter Dönitz aboard U-954. Featuring historically accurate accounts from U-boat commanders Werner Henke, Herbert Werner, and Peter Cremer, this video explains how British cavity magnetron technology created an electromagnetic advantage that changed naval warfare forever. Explore detailed convoy battles including HX 229/SC 122, ONS 5, and SC 130, the 75% U-boat casualty rate, Type XXI submarines, schnorkel systems, and how Allied centimetric radar won the Battle of the Atlantic. Based on declassified interrogation reports, German naval archives, and authenticated World War II historical sources. Perfect for history enthusiasts interested in WWII technology, submarine warfare, radar development, and the decisive turning points that shaped the outcome of World War 2.
