The Chief of Naval Operations Strategic Studies Group (SSG) was established by Chief of Naval Operations Admiral Thomas B. Hayward in 1981. The Group was co-located at the United States Naval War College in Newport, Rhode Island, and received its direction and made its reports only to the Chief of Naval Operations. The SSG was disestablished in 2016 by the Chief of Naval Operations (CNO) Admiral John Richardson.
