Over the past twelve years, the base infrastructure of the United States Air Force (USAF) has shrunk rapidly to accommodate force downsizing engendered by the ending of the Cold War. Still more radical changes are necessary to efficiently support the agile forces required to wage the "Global War on Terrorism." Historically, the ebb, flow, and utilization of Air Force installations are interconnected to changes in the size, composition, and capabilities of major flying and nonflying organizations. As a result, the number of USAF installations has fluctuated according to the complex interaction of the perceived global threat, technology, strategy, tactics, and projected force structure. This study describes military, technical, economic, and political reasoning that has influenced the location, or basing, of major flying and nonflying units in the continental United States, excluding Alaska, between 1907 and 2003. Specifically, it deals with the basing of bomber, fighter, airlift and missile units, training installations, logistic centers, and product centers. Locating flying and nonflying organizations involves assigning them to installations, usually Air Force bases that are compatible with their missions. So closely related is the expansion, contraction, and relocation of USAF force structure to the utilization of base infrastructure that the two subjects must necessarily be considered together. This volume, a preliminary, groundbreaking effort planned and produced within a prescribed period of time, is intended as a reference work offering historical perspective on current basing issues.

"Military history helps provide a realistic perspective on warfare. Through the study of past events, we gain insight into the capabilities of armed forces and, most importantly, a sound knowledge of the policies, strategies, tactics, doctrine, leadership, and weapons that have produced success in battle. Each of us, in broadening our knowledge of air power's past, helps to maintain the most effective Air Force possible, now and in the future."-Foreword. Early in June 1984 some thirty-five of the retired four-star generals of the United States Air Force gathered in Washington, D.C., for the annual Senior Statesmen Conference. Each year since the early 1960s the Air Force has invited its retired four-star generals to Washington. From that group in 1984, the Office of Air Force History invited four general officers—Generals Curtis E. LeMay, Leon W. Johnson, David A. Burchinal, and Jack J. Catton—to participate in a group oral interview on the history of strategic air warfare. They accepted and on June 15, 1984, at Bolling Air Force Base, the four discussed for nearly three hours the development and evolution of strategic air warfare. Because the session ended without time for a discussion of the Cuban Missile Crisis and the Vietnam War, the four conferred again, this time by telephone, to discuss these and other issues not considered earlier. This interview was the third in a series begun by the Office of Air Force History with the "senior statesmen," the first in 1982 covering air superiority in World War II and Korea, the second in 1983 discussing the type of aerial interdiction used in World War II, Korea, and Vietnam.
