"The Pentagon is three in one. It is a building, an institution, and a symbol. As a building, it is one of the wonders of the modem world, an immense and efficient structure created in a mere 16 months between September 1941 and January 1943 – a remarkable feat of conception, design, and construction. As an institution, it is the nerve center of the U.S. military establishment. To the nation and world it is symbolic of American power and influence."
Dr. Alfred Goldberg, Former OSD Historian, The Pentagon: The First Fifty Years
On 17 September 1947, James Forrestal was sworn in as the first Secretary of Defense. The creation of the position was one of the most significant changes in the history of the US military establishment. Ever since, he and his successors have worked to forge the diverse Services and supporting entities into a stronger and more effective defense organization.
The acquisition of major weapon systems consumes a large share of the defense budget and receives extraordinary attention from lawmakers and the public. Although numerous studies have looked in depth at particular weapons programs, the multivolume series—History of Acquisition in the Department of Defense—is the first to provide an overarching account of defense acquisition from 1945 to the close of the 20th century.
