Chief of Naval Operations Strategic Studies Group
The Chief of Naval 0perations Strategic Studies Group (SSG) was established by Chief of Naval Operations Admiral Thomas B. Hayward in 1981. The Group is co-located at the United States Naval War College in Newport, Rhode Island, but receives its direction and makes its reports only to the Chief of Naval Operations.
The current mission of the Strategic Studies Group is to "generate revolutionary naval warfare concepts. Revolutionary implies that the concepts would upset the existing order. Therefore, these concepts are non-consensual. The SSG focuses its efforts on warfighting concepts that appear to have great potential, but Navy organizations are currently not pursuing. In conducting this mission, the SSG is at the leading edge of the Conceptualization Phase of the Process for Naval Warfare Innovation."
