An amazing family story by ENS Ray Kethledge, USN. ENS Kethledge is currently attending the Cryptologic Warfare Officer Basic Course (CWOBC) at Corry Station Pensacola.
"During the early years of World War II, my great-grandfather, Raymond W. Ketchledge, earned his bachelor’s and master’s degrees in electrical engineering from the Massachusetts Institute of Technology. After graduation, he joined Bell Telephone Laboratories—a leading technology company in those days—to design military devices.
In the winter of 1942, my great-grandfather traveled to upstate New York to visit his parents for Christmas. That year had been a trying one for the Allies: Nazi Germany occupied most of Europe, from France to western Russia. And America—which had been in the war for only a year—already faced intense naval battles in both the Pacific and Atlantic oceans".

The Battle of the Atlantic would soon turn in the Allies’ favor, and in no small part because of my great-grandfather’s invention. At Bell Labs, he had built the first acoustically-guided torpedo for use against enemy submarines. The “Mark 24 mine,” as it was called (the name was deceptive to hide its true purpose) had a design revolutionary for its time: it contained four hydrophones that could hear a submarine’s propellers and automatically steer the torpedo towards them–both in direction and in depth. And the battery-powered torpedo traveled faster than any submarine could while submerged.
