This volume focuses on intelligence, the collected and interpreted information about adversaries, which is the basis of wise decisionmaking and war. While intelligence is important to all military operations, it is especially significant to air forces, for the targets we choose and the ability to reach and destroy them often determine whether the speed, flexibility, and power of the aerial weapon is used to its utmost capacity to affect the outcome of combat. 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 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. -- From the foreword, page v.
