Institute for Defense Analyses

The Institute for Defense Analyses (IDA) is an American non-profit corporation that administers three federally funded research and development centers (FFRDCs) – the Systems and Analyses Center (SAC), the Science and Technology Policy Institute (STPI), and the Center for Communications and Computing (C&C) – to assist the United States government in addressing national security issues, particularly those requiring scientific and technical expertise. It is headquartered in Alexandria, Virginia.

Two ideas critical to the birth of the Institute for Defense Analyses, also known as IDA, emerged from World War II. The first was the necessity for unifying the several services into a single, coordinated department. The second was the realization of the strength of the relationship between science—and scientists—and national security. The first reached fruition when President Harry Truman signed the National Security Acts of 1947 and 1949, creating the Department of Defense. (In 1947 the Department of War and the Department of the Navy had been combined to create the National Military Establishment. From it the present Defense Department was created in 1949.)

To give the nascent Office of the Secretary of Defense (OSD) the technical expertise and analytic resources to hold its own and to help make unification a reality, James Forrestal, the Department’s first Secretary, established the Weapons Systems Evaluation Group (WSEG) in 1948 to assist OSD and the Organization of the Joint Chiefs of Staff by:

The demands on WSEG were more than its small staff of military and civilian analysts could satisfy, and by the early years of the Dwight Eisenhower administration, there were calls for change. The several options gradually coalesced into one and, in 1955, the Secretary of Defense and the Chairman of the Joint Chiefs of Staff asked James R. Killian, Jr., then President of MIT, to help form a civilian, nonprofit research institute. The Institute would operate under the auspices of a university consortium to attract highly qualified scientists to assist WSEG in addressing the nation's most challenging security problems. And so, in April 1956, IDA was incorporated as a non-profit organization. In 1958, at the request of the Secretary of Defense, IDA established a division to support the newly created Advanced Research Projects Agency (ARPA), later renamed the Defense Advanced Research Projects Agency (DARPA). Shortly after its creation, the mandate of this division was broadened to include scientific and technical studies for all offices of the Director of Defense, Research and Engineering (DDR&E).
