History

Chair	Mike Rounds Republican

The United States Senate Armed Services Subcommittee on Cybersecurity is one of the seven subcommittees within the United States Senate Committee on Armed Services. It was established in 2017 to provide dedicated oversight of the military's cyber operations, information technology, and cyber-related acquisition programs.^[1]

The subcommittee has legislative jurisdiction and oversight responsibility for policies and programs related to cyber forces and capabilities. Its specific responsibilities include:^[2]

• Oversight of Budget Accounts: Procurement of cyber capabilities; cyber-related "train and equip" programs; science and technology affecting cyber operations; and Information Technology base RDT&E.
• Oversight of DOD Offices: The Department of Defense Chief Information Officer; the Principal Cyber Advisor on Military Cyber Force Matters; and the Chief Information Officers of the military departments.
• Oversight of Commands: United States Cyber Command (USCYBERCOM) and the cyber capabilities of other Department of Defense components.

For the 119th United States Congress (2025–2027), the subcommittee is chaired by Mike Rounds (R-SD) with Jacky Rosen (D-NV) serving as Ranking Member.^[3]

The subcommittee was formed at the start of the 115th United States Congress in January 2017 by Senate Armed Services Committee Chairman John McCain. Its creation was a response to the growing threat of cyberwarfare and the need for focused legislative attention on the cyber domain, distinct from the broader "Emerging Threats" portfolio where these issues previously resided.^[1]
