Declassification and Transparency

As NSA/CSS reviews records under the Freedom of Information Act or Mandatory Declassification Review provisions of Executive Order 13526, we will make the material available to the public via the NSA.gov website on the Internet. In addition, NSA/CSS periodically conducts “Special Topical Reviews” of categories of records, such as the Gulf of Tonkin, USS Liberty, UKUSA, and posts those records to this site. Lastly, in accordance with the federal Open Government initiative, we will identify subjects and records for which there is a general public interest. We will meet transparency goals by reviewing those records and including them on this web page.

Under the provisions of Executive Order 13526, (Classified National Security Information), dated 29 December 2009, NSA reviews for declassification all permanently classified documents 25 years or older.

An index of 4,923 entries containing approximately 1.3 million pages of previously declassified documents, which have been released to NARA is provided. The documents are from the pre-World War I period through the end of World War II.

An index of entries containing over 50,000 pages of declassified documents which have been released to NARA in April 2011 is provided. These documents cover a time frame from before World War I though the 1960s.

UFO Documents Index

The documents listed on this page were located in response to the numerous requests received by NSA on the subject of Unidentified Flying Objects (UFO). In 1980, NSA was involved in Civil Action No. 80-1562, “Citizens Against Unidentified Flying Objects Secrecy v. National Security Agency”. Documents related to that ligitation are marked with “*”. “XXXXX” has been inserted in a title if a portion of the title has been deleted prior to release. To select a document click on the document title, and wait for the PDF version to be downloaded to your local viewer. Approximate file sizes are given after each selection for user convenience.
