Unidentified Anomalous Phenomena Records Collection (Record Group 615)

Pursuant to sections 1841-1843 of the 2024 National Defense Authorization Act (Public Law 118-31), the Archivist of the United States established the Unidentified Anomalous Phenomena Records Collection at the National Archives. The collection includes copies of all government, government-provided, or government-funded records relating to unidentified anomalous phenomena, technologies of unknown origin, and non-human intelligence. Agencies are required to identify, organize, and transmit such records for public disclosure with a presumption of immediate release, subject only to specific postponement criteria such as identifiable harm to national security. The collection is assigned Record Group 615 and is being populated on a rolling basis with materials from multiple agencies, including the NSA, OSD, FAA, and others. Digital copies are made available through the National Archives Catalog.
