The Invisible Weapon That Destroyed 43 U-Boats in a Single Month

#history #ww2 #ww2history
May 1943.
Kapitänleutnant Erich Topp, one of Germany’s most decorated U-boat commanders, heard a sound that shouldn’t exist—an electronic pulse coming from empty sky. Minutes later, Allied aircraft appeared out of nowhere. Three days after that, a destroyer found his submarine in complete darkness. By the end of the month, his boat was sunk—and 43 U-boats had vanished from the Atlantic.
What Topp didn’t know: the Allies had deployed centimetric radar, a technology so advanced that German Metox receivers couldn’t detect it. Every U-boat in the Atlantic was suddenly visible, trackable, and vulnerable—while Naval Command remained unaware.
This is the story of how a 10-centimeter radio wave ended Germany’s submarine campaign and reshaped the Battle of the Atlantic, changing the outcome of World War II.
