About this Unit
The National Security Agency (NSA), established in 1952, functions as a key intelligence agency for the United States Department of Defense. Charged primarily with signals intelligence (SIGINT) and information assurance, the NSA plays a crucial role in monitoring, collecting, and analyzing foreign communications and data for national security purposes. Throughout the Cold War and into the digital age, the NSA has adapted to emerging technologies, expanding its cyber operations and cryptographic capabilities. While not a traditional military unit, its close integration with U.S. military operations and intelligence communities has made it indispensable to American defense and security efforts.
