NSA/CSS UFO Document Release

The National Security Agency Central Security Service, which leads U.S. Government efforts in cryptology for signals intelligence and cybersecurity, provides on its website an extensive list of documents in response to numerous UFO-related Freedom of Information Act requests received by NSA. The release of certain documents on the list was prompted by 1980 civil litigation, “Citizens Against Unidentified Flying Objects Secrecy v. National Security Agency.” The files are provided for download in PDF format.
