History

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]
