The Advanced Research Projects Agency, 1958-1974

This document is a comprehensive historical evaluation of the Advanced Research Projects Agency (ARPA) within the U.S. Department of Defense, covering the period from its inception in 1958 through 1974. Commissioned by ARPA to establish an official institutional memory, the study examines the agency's evolution, management style, and major program developments. The report is organized chronologically, detailing the tenures of successive ARPA Directors, including Roy W. Johnson, Austin W. Betts, Jack P. Ruina, Robert L. Sproull, Charles M. Herzfeld, Eberhardt Rechtin, and Stephen J. Lukasik. The study highlights ARPA's origins as a response to the Sputnik 'missile gap' and its initial role as the primary agency for space and ballistic missile defense research. It documents the agency's transition through various phases, including the 'golden age' of the 1960s, the retrenchment and accommodation period, and the eventual shift toward more constrained, low-profile research activities in the 1970s. Key programs discussed include DEFENDER (ballistic missile defense), VELA (nuclear test detection), AGILE (counterinsurgency), and various initiatives in materials science, information processing, and energy conversion. The report emphasizes ARPA's unique management philosophy, characterized by a small, high-quality staff, reliance on Service agents for contracting, and the use of independent technical advisors, particularly the Institute for Defense Analyses (IDA). It also addresses the agency's complex relationship with the Office of the Director of Defense Research and Engineering (DDR&E), the impact of the Vietnam War on its research priorities, and the challenges posed by Congressional scrutiny and changing national security policies. The document concludes with a review of ARPA's role as a 'technological elite' and its efforts to maintain relevance in a changing bureaucratic and political landscape.
