Sunday, January 3, 2021

3 January 1977: NARA assigned Record Group 457 (now "Records of the National Security Agency") to declassified NSA records.

The National Security Agency had several predecessor agencies. Records generated or maintained by these predecessors are included in Record Group 457. For this reason, while the NSA was not established until 1952, it includes records of interest to those researching earlier periods. Many of the records in RG 457 were not created by the NSA/CSS. These records were generated by predecessor agencies, and maintained and used by the NSA/CSS.

Predecessor agencies whose records may be represented in Record Group 457 include subdivisions of the War Department, the Department of the Army, the Department of the Navy, the National Military Establishment, and the Department of Defense.

Other agencies that are heavily represented in RG 457 include the Signals Intelligence Service and its subdivisions, the Army Security Agency and its subdivisions, the Armed Forces Security Agency, subdivisions of the Office of Naval Intelligence, and the United States Air Force Security Service, among others.

About Us

The NCMF directly supports the National Cryptologic Museum (NCM), the first public museum in the U.S. Intelligence Community. We think you will agree it is truly a "museum like no other."

Located adjacent to the National Security Agency (NSA) in Maryland, the NCM houses a priceless collection of artifacts that represent our Nation's history in code making and code breaking, as well as a world class library of cryptologic media. The NCMF acquires the best artifacts for the NCM and supports new educational and interactive exhibits.

The NCMF provides exceptional cryptologic programs throughout the year, encourages young minds to explore cryptology and innovation through valued awards, and hosts educational, cryptology-related exhibits at various community events.

As part of the Foundation's partnership with NSA to build the Cyber Center for Education and Innovation - Home of the National Cryptologic Museum (CCEI-NCM), the NCMF also serves as a leader in the field of cybersecurity - striving to provide the best in educational resources and programs.

The NCMF and NCM share a joint three-fold mission to Educate, Stimulate, and Commemorate. Learn more about our MISSION.
