How a 2-Foot British Hook Pulled 8 U-Boats to the Surface—Germany Called It Devil's Work

In 1943, the Battle of the Atlantic was on a knife's edge. U-boats were sinking Allied ships faster than they could be built — and the weapons designed to stop them kept missing. Then British engineers at the Admiralty Research Laboratory produced something nobody expected: a 2-foot acoustic homing device that could chase a submarine through the dark at 60 metres depth, with no further human guidance needed. Germany had no explanation for what was happening to their boats. Survivors described a sound that followed them. Getting louder. Then nothing.
This is the story of the Mark 24 — the secret weapon that changed the mathematics of submarine warfare, and why the engineers who built it called it simply "the hook."
