Associate Justice of the U.S. Supreme Court Lewis F. Powell, Jr., was one of a small group of people specially selected to accept and integrate ULTRA, the most secret signals intelligence from intercepted and decoded German military radio transmissions, with intelligence from all other sources. From May 1944 to the end of the war in Europe, he served as the ULTRA officer on General Carl Spaatz's United States Strategic Air Forces staff. Earlier, Colonel Powell had served as an intelligence officer with the 319th Bomb Group, the Twelfth Air Force, and the Northwest African Air Forces. He finished the war as Spaatz's Chief of Operational Intelligence in addition to carrying out his ULTRA duties. The Air Force is grateful to Justice Powell for his generosity in giving his time and recollections so that his experiences can be of benefit, through the medium of history, to the Service today and in the future.
