U.S. Fleet Cyber Command (FLTCYBER) is anoperating force of theUnited 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". TheU.S. Tenth Fleet (C10F) was simultaneously reactivated as its force provider.^[4] 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.

FLTCYBER serves as the Navy's Service Cyber Component (SCC) toUnited States Cyber Command (USCYBERCOM) and the Navy's Service Cryptologic Component to theNational Security Agency/Central Security Service. FLTCYBER also reports directly to theChief of Naval Operations as anEchelon II command and is responsible for Navy information network operations, offensive and defensive cyberspace operations, space operations and signals intelligence.^[5][6]

Headquartered atFort George G. Meade, Maryland,^[7] FLTCYBER exercises operational control of globally-deployed Cyber Mission Forces (CMF) through a task force structure aligned to C10F. FLTCYBER is also designated as the JFHQ-C element supportingU.S. Indo-Pacific Command (USINDOPACOM) andU.S. Southern Command (USSOUTHCOM) for the development, oversight, planning and execution of full spectrum cyber operations aligned with other traditional warfighting lines of operation.^[8]

FLTCYBER's roots are in the namesake of its force provider, C10F, which was organized in 1943 to coordinate the allied response to the German U-boat threat and ensure access to the shipping lanes of the Atlantic.

Today, FLTCYBER and the modern U.S. Tenth Fleet ensure the Navy and the Nation have access to systems in the cyber domain.

Department of Defense cyber operations came together under a single organization on 1 October 2000, when United States Space Command (USSPACECOM) formally took control of the Department of Defense computer network attack activities from the Joint Staff. USSPACECOM was eventually dissolved and some its functions merged into the reorganized United States Strategic Command (USSTRATCOM) 1 October 2002.^[9][10]

Navy Cyber operations were originally the responsibility of Naval Computer and Telecommunications Command, Naval Security Group andNaval Space Command, which were combined with 20 other commands into the Naval Network Warfare Command (NETWARCOM) in 2002 to unify network operations, offensive and defensive cyberspace operations, space operations and cryptologic/signals intelligences.

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 command for information operations, networks and space.^[11]

After extensive study, Secretary of Defense Robert Gates directed the creation of a new sub-unified command, USCYBERCOM on 12 November 2008, to operate under the authority of USSTRATCOM.

FLTCYBER was officially created as the Navy SCC to USCYBERCOM on 29 January 2010.^[12] Chief of Naval Operations AdmiralGary Roughead named VADM Bernard J. McCullough III as the commander of both FLTCYBER and C10F, and all subsequent commanders have led FLTCYBER and C10F simultaneously.

In August 2017, President Donald J. Trump announced the elevation of USCYBERCOM from a sub-unified command under USSTRATCOM to a Unified Combatant Command responsible for cyberspace operations. FLTCYBER remains the Navy SCC to USCYBERCOM.^[13]

In April 2019,Navy Space Command (NAVSPACECOM) was established as the service component of theUSSPACECOM, while being commanded by the head of FLTCYBER. Since 2019 the Commander, FLTCYBER, has also simultaneously been Commander, NAVSPACECOM, though the latter post was not formally established until January 2023.^[14][15]
