In 2002, some 23 organizations from several commands, including the former Naval Space Command, Naval Computer and Telecommunications Command, Fleet Information Warfare Center, and Navy Component Task Force - Computer Network Defense were brought together to form Naval Network Warfare Command, emphasizing the organization's focus on the operation and defense of the Navy's networks.
In 2005, with the alignment of Naval Security Group, NETWARCOM brought the former Naval Security Group Activities (NSGAs) under its umbrella and the mission of the command fundamentally changed, making it the Navy's lead for Information Operations, as well as Networks and Space.
The assumption, alignment and integration of Fleet Intelligence Type Commander duties, responsibilities and functions at NETWARCOM in 2008 began a measured and evolutionary process to improve integrated Fleet Intelligence and ISR readiness. This alignment provided a single Fleet champion for ISR and positions Fleet Intelligence for better and timelier support to fleet operations.
In 2009, the Secretary of Defense directed the establishment of U.S. Cyber Command and the establishment of supporting commands to U.S. Cyber Command by each of the services. The chief of naval operations (CNO) officially established U.S. Fleet Cyber Command (FCC) and recommissioned U.S. 10th Fleet on 29 January 2009 in response to this direction.
With the establishment of U.S. Fleet Cyber Command / U.S. 10th Fleet, Naval Network Warfare Command was reorganized and its mission revised to operate and defend the Navy's portion of the Global Information Grid and to deliver reliable, secure Net-centric and Space warfighting capabilities in support of strategic, operational and tactical missions across the Navy.
