Germans Mocked Britain’s Hedgehog Mortar — Until It Started Destroying Their U-Boats

Germans Mocked Britain’s Hedgehog Mortar—Then Their U Boats Started Disappearing Discover the extraordinary British weapons, war machines, military operations, and forgotten stories that helped shape World War II. In 1941, Britain was losing the Battle of the Atlantic, and the depth charge had a deadly weakness: the attacking ship often lost sonar contact just before reaching a U-boat. Then British engineers created the Hedgehog anti-submarine mortar. It looked awkward, fired forward, and produced none of the spectacular explosions sailors expected when it missed. But that silence was its greatest advantage. By preserving sonar contact and detonating only on impact, Hedgehog transformed the mathematics of submarine hunting and became one of the Royal Navy’s most effective answers to the U-boat threat. 00:00 The Fatal Problem With Depth Charges 06:34 Britain Is Losing the Atlantic 13:08 Why U-Boats Were So Difficult to Kill 19:42 The Sonar Blind Zone 26:16 Britain Searches for a New Weapon 32:50 The Hedgehog Is Born 39:24 Why Sailors Distrusted It 45:58 Twenty Four Bombs Fired Forward 52:32 The Secret Behind Contact Detonation 59:06 Silence Becomes an Advantage 1:05:40 Hedgehog Enters Combat 1:12:14 The Kill Rate Begins to Change 1:18:48 U-Boats Lose Their Escape Window 1:25:22 Britain Turns the Atlantic Battle 1:31:56 Why Silence Was the Real Weapon #HedgehogMortar #UBoats #BattleOfTheAtlantic #RoyalNavy #WWII #AntiSubmarineWarfare #GermanUBoats #NavalHistory #WW2History #HistoryDocumentary Subscribe here:    / @britishrecords-d9x
