Royal Navy Engineers Opened a German Torpedo — One Depth Flaw Changed the Entire Atlantic War

Royal Navy engineers cracked open a captured German G7e torpedo in Portsmouth, 1939 — and what they found inside changed the entire Battle of the Atlantic. The weapon that was sinking Allied convoys had a hidden flaw its own designers never noticed. A faulty depth valve was sending every torpedo 2.5 metres deeper than commanded. Ships that should have been destroyed survived. U-boat commanders filed baffled reports. And three engineers in a cold workshop, with nothing but hand tools and a draughtsman's notebook, quietly handed the Allies one of the most valuable secrets of the war — without the enemy ever knowing they'd lost it.
