The VT (Variable Time) proximity fuze was one of the most important weapons secrets of World War II. Developed by the Johns Hopkins University Applied Physics Laboratory, it used a miniaturized radar transmitter and receiver to detonate shells automatically when they passed close to a target — eliminating the need for a direct hit. Deadly against aircraft and shore targets alike, the fuze was a closely guarded secret throughout the war. These two pages from All Hands, November 1945, reveal the secret weapon to the public for the first time.
