The Naval Security Group (NSG) was established during World War II as a specialized unit responsible for signals intelligence, cryptology, and information security for the United States Navy. Its origins trace back to 1935 with the creation of the Navy's Communications Security (COMSEC) organization, but it formally became the Naval Security Group in 1950. Throughout the Cold War, the NSG played a crucial role in intercepting and deciphering enemy communications, contributing significantly to U.S. intelligence efforts. In 2005, the NSG was disestablished and its functions were integrated into the Naval Network Warfare Command (NETWARCOM), marking the transition to modern cyber and information warfare capabilities.
