Boris Morros, formerly a Soviet spy, became an FBI counterspy and reported on the Soble spy ring. Wartime espionage During the Second World War, Soviet espionage agents obtained classified reports on electronic advances in radio-beacon artillery fuses by Emerson Radio, including a complete proximity fuse (reportedly the same fuse design that was later installed on Soviet anti-aircraft missiles to shoot down Francis Gary Powers's U-2 in 1960). Thousands of documents from the National Advisory Committee for Aeronautics (NACA) were photocopied or stolen, including a complete set of design and production drawings for Lockheed Aircraft's new P-80 Shooting Star fighter jet.
