The curriculum of the US Army Air Corps Tactical School in the 1930s developed and taught the theory that a future war with a great power could be settled by precise long range air attacks on that power's industrial base. Phil Haun offers a guided tour through the most salient lectures of the curriculum, highlighting the key elements of the theory, including the presumed ability of the bomber to easily penetrate enemy air defenses, the expected accuracy of bombing from high altitude, and the supposed fragility of modern economies and civilian morale. This was the only air power theory to which a generation of young US Army Air Corps officers was exposed, ensuring that these ideas would be well tested in World War II. In an incisive closing chapter, Haun reviews the strategic bombing campaigns against Germany and Japan and demonstrates how wrong the theory proved to be in practice, critically examines claims of additional dividends, and illuminates the more plausible successes of the bomber offensives.

This book fills a void that has long plagued the historiography of American strategic bombing. Phil Haun has selected the most important lectures from the Air Corps Tactical School that guided the interwar development of American bombing doctrine, and his careful analysis and editing of those lectures are an enormous plus for anyone who wants to know the origins of air power theory for today's US Air Force.
~Mark Clodfelter, author of Beneficial Bombing: The Progressive Foundations of American Air Power, 1917–1945
Phil Haun has rendered a major contribution to our understanding of the thinking that lay behind the American intellectual preparations for future air campaigns at the Air Corps Tactical School in the period before World War II with this selection of lectures given at the school by its faculty members. These lectures, as well as Haun's commentary, will prove of value not only to students, but to scholars as well. Anyone interested in the history of air power should find the book of great interest and use.

Phil Haun's edition of pre–World War II Air Corps Tactical School lectures provides a fascinating firsthand look at planning for known unknowns. Their authors knew that a new war was coming, that airpower would play a major role in its conduct, and that the United States wouldn't be able to avoid getting involved. How these things would happen, though, couldn't yet be known. That made it a clear necessity to envision an unclear future. This book shows how—and how well—that was done.

Phil Haun leverages his 29-year career in the US Air Force, including multiple combat tours as an A-10 pilot, and his broad formal education, to lay out the United States' understanding of air power and evaluate its originality, strengths, and limitations. His crystalline analysis of reprinted lectures delivered in the 1930s at the Air Corps Tactical School (ACTS) reveals a uniquely American approach to air power that the ACTS faculty then operationalized in World War II. The book strips away the myths about US versus British air power to show its essential but not decisive role in the war's outcome and reveals the ACTS lectures as the origin and foundation of US theories of air power.

With the publication of this volume, Phil Haun has done a great service to the study of air power strategy. He has retrieved the original set of lectures delivered at the Air Corps Tactical School (ACTS) in the late 1930s—lectures that have never been published before and laid the foundations for the strategy of high-altitude daylight precision bombing employed by the United States against Germany. Together with his excellent introduction and conclusion, these essays provide great insight into the evolution of air power strategy before World War II.
~Robert J. Art, author of A Grand Strategy for America
I would recommend [this book] highly to anyone interested in the U.S. Army Air Force in World War II, as it provides important background for our bombing strategy in that conflict.
