On 22 December 2023, President Joe Biden signed Public Law 118-31, the National Defense Authorization Act for Fiscal Year 2024. Subtitle C of Title XVIII created an Unidentified Anomalous Phenomena Records Collection at the National Archives and Records Administration (NARA), required government offices to identify and review UAP-related records, and established standards for transmission, public disclosure and postponement.
The law marked a shift from agency-by-agency possession of UAP material towards a centralised archival system. It required the Archivist to begin establishing the collection within 60 days, directed agencies to review and organise their holdings within 300 days, prohibited destruction or alteration of responsive records, and required public-release decisions to be made under specific statutory standards. The collection's defined scope extends beyond records labelled 'UAP' to government, government-provided and government-funded records relating to UAP, technologies of unknown origin and non-human intelligence, excluding temporarily non-attributed objects.
The enacted provisions were narrower than the July 2023 Schumer-Rounds proposal. The Senate version had included a presidentially appointed review board, a controlled-disclosure campaign and federal eminent-domain authority over alleged recovered technologies and biological material. The conference agreement retained the records collection, transfer requirements and disclosure standards but removed those mechanisms.
Chronology
July 2023 Senators introduced the broader UAP Disclosure Act proposal.

Context and mandate
From the UAP Disclosure Act to the FY2024 NDAA
On 14 July 2023, Senators Chuck Schumer and Mike Rounds, joined by Marco Rubio, Kirsten Gillibrand, Todd Young and Martin Heinrich, introduced the UAP Disclosure Act of 2023 as an amendment to the FY2024 NDAA. The proposal was explicitly modelled on the President John F. Kennedy Assassination Records Collection Act and was designed to centralise UAP records, create a presumption of disclosure and establish an independent review structure.
The proposed act was unusually ambitious. It would have created a UAP Records Review Board composed of presidential appointees confirmed by the Senate; given that board authority to recommend immediate release or postponement; required a controlled-disclosure campaign for withheld material; and directed the federal government to exercise eminent domain over any recovered technologies of unknown origin or biological evidence of non-human intelligence held by private persons or entities.
The Senate adopted the broader architecture, but the House had no comparable provisions. The FY2024 NDAA conference report records that the House receded only with an amendment. The final agreement kept the government-wide records collection, transfer duties and disclosure-review standards, while dropping the independent review board, its staff, the controlled-disclosure process and eminent-domain authority.
22 December 2023: what Congress enacted
The final law placed the UAP provisions in Subtitle C of Title XVIII, Sections 1841 through 1843. Those sections form a linked archival process: Section 1841 creates and defines the collection; Section 1842 directs government offices to identify, review, preserve and transmit records; and Section 1843 specifies when disclosure may be postponed.
Section 1841: a dedicated National Archives collection
Section 1841 directed the Archivist to commence establishment of the Unidentified Anomalous Phenomena Records Collection within 60 days of enactment. It also required preservation of the physical integrity and provenance of records and directed NARA to prepare a subject guidebook and index.
The scope is deliberately broad. The collection is to contain record copies of government, government-provided and government-funded records relating to unidentified anomalous phenomena, technologies of unknown origin and non-human intelligence, or equivalent subjects under other names, with a specific exclusion for temporarily non-attributed objects. This language determines what records must be searched for and organised; it does not operate as a finding that any particular technology or intelligence category exists.
Section 1841 also requires the collection to be preserved, digitised and made available through NARA, including its online database. Congress assigned continuing oversight jurisdiction to specified Senate and House committees, creating a durable legislative interest in the collection rather than a one-time declassification exercise.
Documentary analysis
Section 1842: government-wide identification, preservation and transfer
Section 1842 places the principal workload on the agencies that hold the records. Each government office must identify and organise responsive material, prepare it for transmission to NARA and retain custody while review is under way. Within 300 days of enactment, agencies were required to review and organise each UAP record in their custody for public disclosure and transmission.
The preservation rules are unusually explicit. Responsive UAP records may not be destroyed, altered or mutilated. Records that had already been publicly released before enactment may not be reclassified, newly redacted or withheld under the new process. The law also gives priority to records not previously public, records most directly related to UAP, technologies of unknown origin and non-human intelligence, records already subject to Freedom of Information Act litigation, and older records where feasible.
NARA was directed to create a standard identification aid so records could be catalogued uniformly across agencies and formats. This requirement later became a detailed metadata system specifying identifiers, titles, dates, originators, classification/restriction status and other descriptive fields.
Disclosure and the 25-year rule
The statute requires agencies to transmit records that can be publicly disclosed and to transfer postponed records into the protected portion of the collection. Postponed and redacted records are subject to periodic review. Continued postponement requires an unclassified written explanation supplied to the Archivist and published in the Federal Register.
A notable feature is the 25-year disclosure rule: each UAP record is to be released in full no later than 25 years after its first creation by the originating body, unless the President certifies that continued postponement is necessary because an identifiable harm to military defence, intelligence operations, law enforcement or foreign relations outweighs the public interest in disclosure. For older records, that creates a presumption that any continuing restriction requires an affirmative justification rather than indefinite inertia.
Section 1843: grounds for postponement
Section 1843 does not require indiscriminate declassification. It permits postponement where the original classification authority finds clear and convincing evidence that disclosure would create sufficiently grave harm under specified categories, including protection of intelligence agents, sources and methods; military or foreign-relations interests; personal privacy; law-enforcement activity; and confidential cooperation with foreign governments.
The significance lies in the structure of the test. The law pairs a broad collection mandate with stated withholding grounds and periodic review, rather than leaving UAP records solely within ordinary agency filing systems. That framework creates a traceable archival process even when a record cannot initially be released in full.
Outcomes and legacy
What did not survive the conference
The conference report is explicit about the elements removed from the Senate version. The final law did not create the proposed independent UAP Records Review Board, did not establish a board staff or executive director, did not retain the controlled-disclosure campaign, and did not enact federal eminent-domain authority over alleged recovered UAP material.
Schumer and Rounds addressed the compromise on the Senate floor on 13 December 2023. In their colloquy, both described the records collection as meaningful progress while identifying the absence of an independent review board and material-acquisition authority as major shortcomings.
This distinction is central to the historical record. The enacted statute created a legally significant archival and disclosure framework, but it left initial disclosure determinations with the government offices and original classification authorities that hold the records. The more independent JFK-style adjudicative mechanism proposed in July 2023 was not enacted.
Implementation: 2024–2025
NARA began implementation quickly. A 6 February 2024 memorandum instructed federal records managers to begin identifying responsive records and previewed the metadata NARA would require. On 9 May 2024, NARA issued detailed agency guidance and a standardised identification system for digital copies and metadata.
By October 2024, NARA had established a transfer schedule for publicly releasable material and assigned responsive records to a dedicated archival group. The agency later confirmed the establishment of Record Group 615, Unidentified Anomalous Phenomena Records Collection, and began receiving records from federal agencies on a rolling basis.
On 24 April 2025, NARA announced a substantive public release of records transferred from ODNI, the Office of the Secretary of Defense, the Federal Aviation Administration and the Nuclear Regulatory Commission. The release demonstrated that the 2023 statute had moved beyond an abstract mandate into an operating records-transfer system. Subsequent transfers expanded the collection to additional agencies.
Historical significance
The FY2024 NDAA is one of the most consequential transparency statutes in the modern U.S. UAP chronology because it changes the location and lifecycle of the documentary record. Earlier UAP initiatives concentrated on reporting, analysis and investigation. Sections 1841-1843 instead address preservation, identification, archival custody and public access across the federal government.
The law also creates a durable research infrastructure. A centralised collection with standardised metadata allows records from different agencies and eras to be compared without relying solely on agency-specific FOIA searches or scattered historical holdings. That has direct value for reconstructing institutional history even where individual records contain conventional explanations or remain partially restricted.
At the same time, the final compromise matters as much for what it retained as for what it removed. Congress enacted centralisation and structured disclosure review, but not an independent review board. The resulting system therefore increases archival visibility while preserving substantial agency control over classification and postponement decisions.
Evidence assessment
The documentary confidence for this event is very high. The operative text is contained in Public Law 118-31, the conference report identifies the provisions retained and removed during negotiation, and NARA's subsequent guidance shows how the statute was translated into a functioning archival process. The event is therefore unusually well suited to a records-based assessment rather than inference from participant recollection.
First, the enacted law represents a genuine structural change in U.S. UAP transparency. Unlike earlier one-off reporting requirements, the statute created a permanent archival process: It required a permanent National Archives collection, government-wide record identification, preservation rules, standardised cataloguing, transfer procedures, public-access mechanisms and recurring review of withheld material. Those features change how UAP records are managed across agencies and create an archival trail that can be tested over time.
Second, the breadth of the statutory search terms is historically notable. Congress required agencies to capture records relating not only to UAP but also to 'technologies of unknown origin' and 'non-human intelligence' or equivalent subjects. The evidential significance of those phrases is procedural: they prevent potentially responsive records from escaping review because an agency used different terminology. Their presence in the statute is evidence of the scope Congress wanted searched, not an adjudication that such technologies or intelligence had been established.
Third, the final conference compromise materially weakened the independence of the proposed disclosure process. The Senate's UAP Disclosure Act would have created a presidentially appointed, Senate-confirmed review board modelled on the JFK Assassination Records Review Board. That mechanism would have placed an external body between agency classification decisions and final disclosure recommendations. The conference agreement removed it, leaving the original classification authorities and existing executive mechanisms central to postponement decisions. This is the clearest substantive difference between the July proposal and the law enacted in December.
Fourth, the statute still contains meaningful disclosure pressure. Previously public records cannot be pulled back into secrecy through the new process; postponed records require periodic review; continued postponement must be explained; and the 25-year rule creates a presumption of full release for older material unless the President certifies a specific continuing harm. These provisions are stronger than a simple instruction to agencies to 'review for declassification,' although their effectiveness depends on agency compliance, resourcing and the quality of NARA's oversight.
Fifth, the implementation record confirms that the law had practical effects. NARA issued government-wide guidance, standardised metadata, established Record Group 615 and began receiving material from multiple agencies. The April 2025 public release provides a concrete implementation marker. The size, completeness and historical value of the collection remain open empirical questions that can only be assessed as transfers continue.
The available evidence therefore supports treating the 22 December 2023 enactment as a major archival and transparency milestone. Its strongest evidential significance is institutional: Congress converted a long-standing public demand for UAP records into a cross-government preservation and disclosure process housed at the National Archives. The law is less expansive than the original Schumer-Rounds proposal, but it created infrastructure capable of changing the documentary basis on which future historical claims are evaluated.
