The National Security Agency is divided into two major missions: the Signals Intelligence Directorate (SID), which produces foreign signals intelligence information, and the Information Assurance Directorate (IAD), which protects U.S. information systems.[8]
Headquarters for the National Security Agency is at Fort George G. Meade, Maryland, about 15 mi (24 km) southwest of Baltimore. The NSA has its own exit off Maryland Route 295 South labeled “NSA Employees Only.” The scale of the operations at the NSA is hard to determine from unclassified data; some 18,000 parking spaces are visible in photos of the site. In 2006, the Baltimore Sun reported that the NSA was at risk of electrical overload because of insufficient internal electrical infrastructure at Fort Meade to support the amount of equipment being installed. This problem was apparently recognized in the 1990s but not made a priority, and “now the agency’s ability to keep its operations going is threatened.”[9] Its secure government communications work has involved the NSA in numerous technology areas, including the design of specialized communications hardware and software, production of dedicatedsemiconductors (at the Ft. Meade chip fabrication plant), and advanced cryptography research. The agency contracts with the private sector in the fields of research and equipment.
In addition to its Ft. Meade headquarters, the NSA has facilities at the Texas Cryptology Center in San Antonio, Texas; at Fort Gordon, Georgia, and elsewhere. (See also Friendship Annex.)
On January 6, 2011 a groundbreaking ceremony was held to begin construction on the NSA’s first Comprehensive National Cyber-security Initiative (CNCI) Data Center; the “Utah Data Center” for short. The US$ $1.5 billion data center is being built at Camp Williams, Utah, located 25 miles (40 km) miles south of Salt Lake City. The data center will help support the agency’s National Cyber-security Initiative.[10]
