Declassified UAP & UFO Documents: Global FOIA Repositories

Location: Entirely online at the CIA website (cia.gov/readingroom). FOIA correspondence and inquiries are directed to the Information and Privacy Coordinator, Central Intelligence Agency, Washington, DC 20505. (CIA headquarters is in Langley, Virginia; the Reading Room itself is a digital public portal, not a physical research facility.)

Conditions of access to archival material:
Free and open public online access to documents previously released under the Freedom of Information Act (FOIA), Mandatory Declassification Review, and other CIA release programs. Materials are searchable via the site’s search tools and organized into collections. Documents are typically provided as PDFs and may contain redactions under applicable FOIA exemptions. No registration is required to view or download released records.

New FOIA requests can be submitted online or by mail/fax to the address above. The Electronic Reading Room is provided as a public service by the Directorate of Digital Innovation’s Information Management Services. Not every CIA record is in the Reading Room; researchers may also submit new requests for additional material.

Description of the CIA:
The Central Intelligence Agency (CIA) is the United States’ principal foreign intelligence service, responsible for collecting, analyzing, and disseminating foreign intelligence and conducting covert action as directed. The FOIA Electronic Reading Room is an official public-access portal maintained by the Agency to make available documents released under FOIA and related declassification programs. It supports transparency by providing online access to previously classified or withheld records once they have been reviewed and cleared for release.

Description of the CIA archive generally:
The CIA FOIA Electronic Reading Room is an online repository of declassified and FOIA-released CIA documents, including topical historical collections, the large CREST (CIA Records Search Tool) archive of 25-year-program records, and materials on a wide range of intelligence subjects. It serves as the primary public portal for reviewing Agency records that have been released to the public.

Description of UAP specific material:
The principal UAP/UFO resource is the “UFOs: Fact or Fiction?” collection. According to the CIA’s own description, this collection catalogues Agency information on the subject from the 1940s through the early 1990s. Most of the documents consist of CIA cables reporting unsubstantiated UFO sightings appearing in the foreign press and intra-Agency memoranda about how the Agency handled public inquiries about UFO sightings.

The collection page directs readers to the 1997 Studies in Intelligence article “CIA’s Role in the Study of UFOs, 1947–1990” by Gerald K. Haines (Center for the Study of Intelligence) for the most comprehensive official historical overview available at the time of the collection’s presentation. That study, based on an Agency-wide file review ordered in late 1993 by DCI R. James Woolsey, concludes that while CIA concern over UFOs was substantial until the early 1950s (including monitoring of Air Force investigations and participation in the 1953 Robertson Panel), the Agency thereafter paid only limited and peripheral attention to the phenomena. The review found no evidence of a direct national-security threat from the reported objects and no evidence of extraterrestrial visits. A significant portion of 1950s–1960s sightings were later assessed as related to classified high-altitude reconnaissance flights (U-2 and OXCART/A-12 programs).

Official title: Unidentified Anomalous Phenomena Records Collection (Record Group 615), established under sections 1841–1843 of the 2024 National Defense Authorization Act. The broader research portal is titled “Records Related to Unidentified Flying Objects (UFOs) and Unidentified Anomalous Phenomena (UAPs) at the National Archives.”

Location: Primary research facility is the National Archives at College Park, 8601 Adelphi Road, College Park, MD 20740-6001. The National Archives Building (headquarters and museum) is at 700 Pennsylvania Avenue NW, Washington, DC 20408. Most UAP/UFO research materials and electronic records access are handled at College Park.

Conditions of access to archival material
Publicly releasable digital copies are made available online through the National Archives Catalog (catalog.archives.gov) on a rolling basis as agencies transfer them. Items in the Catalog are downloadable and may be republished with attribution to NARA. Bulk downloads (ZIPs of digital objects plus JSON metadata) are also offered for UAP-related Catalog content.

Some materials (especially certain moving images, sound recordings, or items with donor/copyright/IP restrictions) are not online and require onsite viewing in the appropriate research rooms at the National Archives at College Park. Research room hours are typically Monday–Friday, 9 a.m.–5 p.m.; appointments are highly encouraged. Publicly releasable records are unrestricted once released; agencies must transfer both redacted public-use and full-text versions where redactions apply. Contact inquire@nara.gov for reference inquiries.

Physical size of material:
Project Blue Book textual records (RG 341 and related) are described by NARA as approximately 2 cubic feet of administrative/project files, 37 cubic feet of case files, and 3 cubic feet of related Office of Special Investigations records (roughly 42 cubic feet total; a cubic foot is about 2,000 pages). Access to the main textual case files is via 94 rolls of 35 mm microfilm (Publication T-1206). Motion pictures, sound recordings, and still pictures are held separately in specialized branches.

RG 615 is digital-only (NARA accepts only digital copies; original source records remain with the originating agencies under their disposition schedules). Overall physical size of all NARA UAP-related holdings is not quantified beyond the Blue Book figures, as materials are dispersed across multiple record groups and media types.

Description of NARA
The National Archives and Records Administration (NARA) is an independent federal agency established in 1934. Its mission is to preserve, protect, and share the historical records of the United States to promote public inquiry and strengthen democratic participation. It identifies, preserves, and provides public access to historically valuable records of the federal government (typically only 1–3% of all records created), including textual records, photographs, moving images, electronic records, and more. NARA operates the National Archives Building in Washington, DC, the National Archives at College Park, Presidential libraries, regional facilities, the Office of the Federal Register, and related programs. It is the nation’s official record keeper for permanent federal

NARA maintains permanent federal records of historical value across numerous record groups. For the UAP topic, this includes longstanding holdings (especially Air Force Project Blue Book and related investigations) plus the new dedicated Record Group 615 for digital copies of UAP records transferred from federal agencies under the 2024 NDAA. A dedicated research topic page organizes access to both.

Description of UAP specific material

NARA’s UAP/UFO holdings fall into two main categories:

1. Pre-existing records across multiple record groups (documented on the main UAP topic page and subpages for textual/microfilm, moving images/sound, presidential libraries, and by record group). The largest and best-known is Project Blue Book (U.S. Air Force UFO investigation program, 1947–1969), which logged 12,618 sightings of which 701 remained unidentified at closure. Holdings include administrative files, chronological case files, OSI-related records, microfilm (T-1206), motion picture films, sound recordings, and some still pictures/artifacts. Related materials appear in RG 341 (Headquarters U.S. Air Force/Air Staff), RG 342 (Air Force Commands), and others. Additional records come from the CIA, NASA, FAA (e.g., Japan Airlines Flight 1628 materials), Office of the Secretary of Defense, Navy installations, Allied WWII headquarters, U.S. Information Agency, and more. These include reports, correspondence, photographs, films (e.g., Major General John A. Samford’s 1952 “Flying Saucers” statement), and Roswell-related source files. Many are cataloged with National Archives Identifiers and some are digitized.
2. Record Group 615: Unidentified Anomalous Phenomena Records Collection. Created specifically under the 2024 NDAA, this consists of digital copies of “all Government, Government-provided, or Government-funded records relating to unidentified anomalous phenomena, technologies of unknown origin, and non-human intelligence (or equivalent subjects by any other name with the specific and sole exclusion of temporarily non-attributed objects).” Agencies identify records in any format, create digital copies (with required metadata), and transfer them to NARA on a rolling basis. NARA accessioned these into RG 615 and makes publicly releasable copies available online in the Catalog. Series received or listed include materials from the Federal Aviation Administration, U.S. Nuclear Regulatory Commission, Office of the Director of National Intelligence, Office of the Secretary of Defense, National Security Agency, Department of State, Federal Bureau of Investigation, Department of the Air Force, and U.S. Customs and Border Protection. Content includes reports, annual assessments, historical documents, videos (e.g., CBP infrared footage), and other agency records. The collection continues to expand as additional transfers arrive. NARA issued guidance to agencies on identification, preparation, and transfer (including handling of redactions).

A dedicated bulk-download page supports large-scale research on digitized and born-digital UAP-related Catalog objects. The overall portal (including subpages for different media types and RG 615) serves as the central public finding aid.
