Thirty Air Force UAP Records Reach the National Archives Catalog, 27 August 2026
Thirty Department of the Air Force records covering 1945 to 1969 appeared in the National Archives catalog under Record Group 615, nearly three months after the same files surfaced in the Archives' cloud storage and vanished within a day. The batch contains at least one detailed 1948 sighting report that had never been readily public.
What happened
On 27 August 2026 thirty Air Force records on unidentified anomalous phenomena appeared in the National Archives catalog. The series had been unavailable to the public until that day. The find was reported by a researcher publishing under the name HM05. The series carries National Archives Identifier 656595571 and the title Records from the Department of the Air Force Relating to Unidentified Anomalous Phenomena, October 25, 1945 to December 31, 1969. It sits inside Record Group 615, the Unidentified Anomalous Phenomena Records Collection.
The catalog entry states that the series consists of records compiled in response to the 2024 National Defense Authorization Act, Public Law 118-31, and received from the Department of the Air Force pursuant to the Unidentified Anomalous Phenomena Records Collection Act, 44 U.S.C. 2107 note. It lists the creators as the Department of the Air Force, from 26 September 1947, and its predecessor the War Department Army Air Forces, from 20 June 1941 to 26 September 1947. The holdings are textual records, arranged by assigned identifier, in English. Access is marked Unrestricted and Use is marked Unrestricted. The series is flagged Partially Available in the Catalog, with thirty items and thirty digital objects currently viewable.
The thirty items are a mixture of unit histories, correspondence files and individual documents. They include the 27th Fighter-Escort Wing histories for March 1950 and December 1952, the 57th Fighter-Interceptor Wing history for June 1950, the Curtis LeMay Collection for 1945 to 1947, the History of MacDill Field Florida for July 1947, the 178th Fighter Bomber Squadron history for April 1951, both volumes of the 4602d Air Intelligence Service Squadron history for June 1955 and June 1956, several Air Division histories, the 72d Strategic Reconnaissance Wing history for April 1953, three separate files of Correspondence Regarding Unidentified Flying Objects dated 1947, 1949 and 1952, a January 1953 item titled Lights Seen Over Japan, Air Force Regulation No. 200-2 of 20 July 1962, Headquarters Alaskan Air Command Regulation 200-5 of 24 December 1953, A Survey of Exobiology from March 1963, a Project Blue Book item from 18 April 1966 titled I Once Saw A Flying Saucer, and a Fifth Air Force Daily Intel Summary for June 1952.
Documents and images
What is the official position?
The legal machinery behind this release is on the record and is worth stating precisely, because it sets the deadlines the release has missed. The 2024 National Defense Authorization Act, Public Law 118-31, was signed on 22 December 2023 and carried the Unidentified Anomalous Phenomena Records Collection Act, now codified at 44 U.S.C. 2107 note. The statute required each head of a Government office to review, identify and organize each unidentified anomalous phenomena record not later than 300 days after enactment, with transfer to the Archives due by 30 September 2025 and online availability required within 180 days after that.
The National Archives has published no statement explaining the timing, and none of the individual records carries a public note about it. What the documents themselves show is the declassification authority. The cover sheet of one item in the batch carries a Department of the Air Force, Air Force Declassification Office block reading Authority: FY24 NDAA, now codified at 44 U.S.C. 2107, with the date 5/05/2025, the box Declassified in Full checked, and Case Number 342UAP00005. That is the mechanism running underneath the whole collection: individual Air Force files reviewed and released in full in May 2025 under the NDAA authority, then routed to the Archives.
The sequence in between is the part that has drawn attention, and the account of it comes from the researcher rather than from the government. HM05 reports that on 2 June 2026 thirty Air Force records appeared in the National Archives' Amazon S3 storage, and that by 3 June 2026 the links were dead, the files having been withdrawn before they were ever published to the catalog. The account states that metadata for the records had been obtained through a Freedom of Information Act request on 29 September 2025, that all thirty showed as declassified in May 2025, and that comparable FBI and State Department records released into the same collection went from S3 appearance to publication within a day, making the Air Force withdrawal the only such incident documented. This archive has not independently confirmed the June appearance and removal, which rests on one researcher's contemporaneous account, and says so plainly. What is independently confirmable is the endpoint: the series is in the catalog now, it holds thirty items, and the item this archive downloaded and read carries a May 2025 declassification stamp.
What the people involved say
There is no witness in the usual sense here, because the event is an act of records administration rather than a sighting. The people who matter are the researcher who tracked the files and the two Air Force officers whose report sits inside them.
The researcher publishes as HM05 and posted the finding to the r/UFOs community on 27 August 2026 with a link to the catalog series and to a longer written account. Asked in the thread whether the batch contained anything substantial, they answered candidly rather than promotionally, saying they had not seen anything substantial in the batch and had not dug deeply into all of the records. They then made the observation that explains the shape of the collection better than any official description: a single mention of unidentified anomalous phenomena can qualify a record for inclusion, so a thousand page unit history with one relevant paragraph gets transferred whole, and the researcher has to hunt for the part that matters. Their conclusion was that including such records is still important, but that their inclusion alongside the exclusion of records more directly covering the subject highlights a problem with how these releases are being made. A second commenter added that some of the records are close to unreadable without extra image processing.
That assessment is borne out by the item this archive examined. It is titled Estimate of the Situation, September 8, 1948, a name that collides with one of the most argued about documents in the history of the subject, the Air Technical Intelligence Center estimate that General Hoyt Vandenberg is said to have rejected in 1948. It is not that document. It is a Headquarters Fifth Air Force theater intelligence estimate covering 7 August to 4 September 1948, twenty one pages on Japan, Korea, China, Turkey and French Indo-China, and its relevance to this collection is a single section on page fourteen. That section, headed Spheroid Airborne Objects Sighted over Alaska, is a detailed account of about twenty unidentified objects seen by two officers of the 72nd Reconnaissance at Fielding Lake on 9 July 1948, and it is the most substantive UAP content this archive found in the batch.
Is the Thirty Air Force UAP Records Reach the National Archives Catalog, 27 August 2026 real? The two-pass assessment
Pass one, what is mundane here. Almost all of it, and that is the point rather than a criticism. This is a statutory records transfer working roughly as designed but slowly, and there is no need to reach for anything exotic to explain a government archive missing a deadline. Agencies routinely run late, digitisation queues are long, and a catalog publication is a clerical event. The June appearance and withdrawal is the one element that invites a darker reading, and it should be held loosely: files being pulled from cloud storage before publication is entirely consistent with an ordinary processing error, a metadata problem, or a review that was not finished, and no source has established otherwise. The researcher who documented it does not claim otherwise either.
The collection's contents are also mundane in a specific and useful way. A collection assembled by keyword inclusion produces exactly what this batch is, mostly unit histories and correspondence in which the subject appears in passing. Nothing in the thirty items announces itself as a revelation, and the researcher who found them said so first.
Pass two, what actually changed. Two things, and neither depends on any claim about the phenomenon itself.
The first is that the inclusion rule cuts both ways. A criterion loose enough to sweep in a thousand page wing history for one paragraph is also loose enough to surface material nobody was looking for, and it did. The Fifth Air Force estimate is a routine theater intelligence document that no researcher would have requested, and buried on page fourteen of it is a first hand military account of a twenty object formation with an acoustic signature, together with a line recording that the Air Force checked for fighter formations in the area and found none. That passage is now public, and the sighting it describes has its own case file in this archive.
The second is a caution about titles. Estimate of the Situation, September 8, 1948 is a catalog entry that will be misread, and predictably so, because the phrase belongs to a famous lost document about flying saucers. The file behind that title is a Far East theater intelligence summary. This archive downloaded the forty eight page scan, read it, and states the identification plainly so that the collision does not propagate. That is the practical lesson of this release for anyone working it: the titles in Record Group 615 describe the parent document, not the anomalous content inside it, and the only way to know what a record holds is to open it.
No tier of the usual kind applies to a records release, and this case is filed Unknown because there is no official narrative to weigh, only a catalog entry and a statute. What can be said without hedging is the verifiable part. The series is real, it is public, it holds thirty items under Record Group 615, its legal basis is Public Law 118-31, at least one of its documents was declassified in full on 5 May 2025 under case number 342UAP00005, and at least one of them contains a detailed 1948 military sighting report that had not previously been easy to find.
