U.S. Cyber Command’s network defense arm has officially been designated as a sub-unified command.

Congress directed Joint Force Headquarters-Department of Defense Information Network (JFHQ-DODIN) to elevate to a sub-unified command under Cybercom in the fiscal 2025 annual defense policy bill.

JFHQ-DODIN was created in 2015 as a subordinate headquarters under Cyber Command to protect and defend the Pentagon’s network globally. It’s led by a three-star general who also serves in a “dual-hat” role as the director of the Defense Information Systems Agency, a much bigger combat support agency providing critical IT services to warfighters.

Secretary of Defense Pete Hegseth directed that JFHQ-DODIN be designated a sub-unified command, effective immediately May 28, and its name has been changed to Department of Defense Cyber Defense Command (DCDC).

The name change was a recognition of the command’s ability to execute authority, direction and control over cyberspace forces, according to Steve Mavica, a spokesman for DCDC.
