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 (NETWARCOM or NNWC)), 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.
In 2009, the Secretary of Defense directed the establishment of U.S. Cyber Command. Each of the services was also directed to establish a supporting command to U.S. Cyber Command. Naval Network Warfare Command was reorganized and its mission revised to operate and defend the Navy's portion of the Global Information Grid and deliver reliable and secure Net-centric and Space warfighting capabilities in support of strategic, operational and tactical missions across the Navy.
