Federally Funded Research and Development Centers (FFRDCs) evolved primarily from research facilities designed to meet the special needs of World War II. Presented by the National Science Foundation, this Web site provides a current listing of 36 FFRDCs located in the US, along with descriptions. Users can view the master list, arranged by departments; or view the centers by "geographic location" or "categories of activity," with the latter consisting of three different sections -- research and development labs, study and analysis centers, and systems engineering and integration centers. Also included is a FFRDCs criteria list and a section on "Decertifications, Closures, Renaming, and Other Notes Associated with FFRDCs" between 1968-2001.
