This official history was originally printed in very small numbers in 2002. "Defense's Nuclear Agency, 1947-1997" traces the development of the Armed Forces Special Weapons Project (AFSWP), and its descendant government organizations, from its original founding in 1947 to 1997. After the disestablishment of the Manhattan Engineering District (MED) in 1947, AFSWP was formed to provide military training in nuclear weapons' operations. Over the years, its sequential descendant organizations have been the Defense Atomic Support Agency (DASA) from 1959 to 1971, the Defense Nuclear Agency (DNA) from 1971 to 1996, and the Defense Special Weapons Agency (DSWA) from 1996 to 1998. In 1998, DSWA, the On-Site Inspection Agency, the Defense Technology Security Administration, and selected elements of the Office of Secretary of Defense were combined to form the Defense Threat Reduction Agency (DTRA).

Right after World War II, the United States felt secure in its atomic monopoly. With the American "Pax Atomica" in place, the free world held an apparent strategic advantage over the Soviet bloc and saw itself as a bulwark against communist expansion. But America's atomic superiority in the early postwar years was more fiction than fact. From 1945 until 1950, the U.S. atomic arsenal was poorly coordinated, equipped and funded. The newly formed Atomic Energy Commission inherited from the Manhattan Engineer District a program suffering from poor organization, failing infrastructure and internal conflict. The military establishment and the Air Force's Strategic Air Command little knew what to do with this new weapon. The Air Force and the AEC failed to coordinate their efforts for a possible atomic air offensive and war plans were ill-conceived, reflecting unrealistic expectations of Air Force capabilities and possible political outcomes. This lack of preparedness serves as a case study in the tenuous nature of American civilian-military relationships.

This book discusses the decision to use the atomic bomb. Libraries and scholars will find it a necessary adjunct to their other studies by Pulitzer-Prize author Herbert Feis on World War II. Originally published in 1966. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
