The U.S. Fleet Cyber Command is an operating force of the United States Navy responsible for the Navy's information network operations, offensive and defensive cyber operations, space operations and signals intelligence. It was created in January 2010 "to deter and defeat aggression and to ensure freedom of action to achieve military objectives in and through cyberspace". U.S. Tenth Fleet was simultaneously reactivated as its force provider. Since it was founded, the command has grown into an operational force composed of more than 16,000 active and reserve sailors and civilians organized into 27 active commands, 40 Cyber Mission Force units, and 27 reserve commands around the world.
