DOE UAP Files: 3 Department of Energy Documents
The U.S. Department of Energy contributed three files to PURSUE Release 02 on May 22, 2026 - the first time DOE has appeared in this disclosure program. All three files tie to U.S. nuclear-weapons-complex sites and personnel: an incident report from the PANTEX final-assembly plant, 1970s personal correspondence from a Los Alamos physicist named James Tuck on his UAP interest, and a 1986 Pajarito Astronomers club invitation for a UFO talk by another Los Alamos-affiliated physicist that the laboratory itself did not host. The contents are honest about what they are: paper records of agency personnel and adjacent civilian organizations engaging with UAP, not photographic or sensor proof of anything.
Why all three are tied to the nuclear weapons complex
The Department of Energy is not a generic federal agency for these purposes. It is the cabinet-level department that, since 1977, has held responsibility for the U.S. nuclear weapons stockpile, the National Laboratories that designed those weapons, and the related production and dismantlement infrastructure. The released DOE PURSUE files reflect that scope. None of them are about commercial energy policy or solar grids. All three involve nuclear-weapons-complex sites or the physicists who worked on them:
- PANTEX (DOE-UAP-D001) is the U.S. final-assembly and dismantlement plant for nuclear weapons, located near Amarillo, Texas. It is the only facility of its kind in the country.
- James Tuck (DOE-UAP-D002) was a British-born physicist who worked on the Manhattan Project at Los Alamos during World War II and stayed associated with Los Alamos National Laboratory in the decades after. His personal correspondence on UAP is the subject of the file.
- Pajarito (DOE-UAP-D003) is the high plateau in northern New Mexico on which Los Alamos National Laboratory sits. The Pajarito Astronomers club is a civilian organization based in the area, and the 1986 talk on the file's invitation was by another Los Alamos-affiliated physicist.
This is not a coincidence of file selection. DOE has many sites and many personnel that could in principle have UAP-adjacent records. The agency chose to release three files specifically from the nuclear-weapons production and research infrastructure. The choice is informative regardless of what is in the files themselves.
The three files, file by file
D001The released metadata describes this file as "a PANTEX Unidentified Object Incident Report that includes an enhanced image from ground surveillance radar tower." This is the most concrete of the three DOE files: an incident report tied to the country's only nuclear-weapons final-assembly facility, including imagery from PANTEX's perimeter surveillance infrastructure. The released summary does not say when the incident occurred, what the image shows, or how PANTEX security categorized the event - those details would be in the report's body, which the released summary does not reproduce.
The released metadata describes this file as "personal correspondence to and from James Tuck, a Los Alamos National Laboratory-affiliated physicist, regarding his interest in unidentified anomalous phenomena circa 1970s." Tuck is a real historical figure - a British-born physicist who worked on the Manhattan Project's implosion-lens research at Los Alamos during the war and continued to work on fusion-related and explosives-related projects in the post-war decades. The file is described as "personal" correspondence; the released summary does not say what specific UAP topics Tuck wrote about or to whom, and it does not claim Los Alamos as an institution sponsored or directed the interest.
The released metadata is the most carefully worded of the three DOE files. It describes the document as "a letter to the members of the Pajarito Astronomers club regarding an upcoming meeting featuring a presentation from a Los Alamos National Laboratory-affiliated physicist, Dr. John Warren, titled 'Why Should a Scientist be Concerned about UFOs?' The referenced event was not officially hosted by Los Alamos. The laboratory has no record of the subject matter discussed at the meeting." That is the released summary in DOE's own framing - explicitly distancing Los Alamos as an institution from the talk and explicitly noting the absence of a record. This is the structural opposite of a smoking-gun framing, and the released metadata's care here is worth preserving in any retelling. The event was a civilian-club presentation by an affiliated physicist on his own; the institutional record per DOE itself is "we did not host this and we don't know what was said."
The honest read on the cluster
What the three DOE files establish, taken together, is narrower than the "nuclear-UAP connection" framing some popular literature places on government nuclear-program documents. The released summaries support exactly three observations:
- PANTEX (DOE-UAP-D001) generated an internal Unidentified Object Incident Report with enhanced ground-surveillance imagery. The fact that PANTEX has an incident-report process for unidentified objects is unsurprising given its security mission, but the existence of a categorized file in PURSUE confirms one occurred.
- James Tuck (DOE-UAP-D002), a real Los Alamos-affiliated physicist, maintained personal correspondence on UAP topics in the 1970s. The released summary makes clear this was personal, not institutional. Tuck's professional interests during the period were public scientific work on explosives and plasma physics; his personal UAP interest is what was preserved and released.
- A Los Alamos-affiliated physicist (Dr. John Warren) was invited in 1986 to give a UFO talk to a civilian astronomy club on the Pajarito Plateau. DOE's released metadata explicitly notes Los Alamos did not host the talk and has no institutional record of its content.
What the three files do not establish:
- They do not establish that PANTEX has had multiple UAP incidents (the release contains one report).
- They do not establish that Los Alamos as an institution had a UAP research program, formal or informal. The two Los Alamos-adjacent files are explicitly framed as personal-Tuck and not-officially-hosted-Warren.
- They do not establish what was in the PANTEX surveillance image or what the Tuck correspondence said about UAP.
- They do not establish anything about the older or more famous nuclear-weapons-and-UFO claims surrounding sites like Malmstrom AFB (Air Force, not DOE), Oak Ridge (not in this release), or the Manhattan Project era. Those are different research threads addressed by different files in other archives.
Why these scored 50 on the rubric
All three DOE files default-score to 50 on this site's six-axis open rubric. The components: sensor_quality: eyewitness_only (these are paper records, not instrumented captures - though DOE-UAP-D001 references ground-radar imagery that the released summary does not include directly), witness_credibility: federal_agent (DOE personnel), corroboration: single_witness_instrument (the rubric's universal baseline), kinematic_anomaly: no_kinematic_data (no instrumented measurements published), mundane_explanation_available: weak_mundane_candidate (the rubric baseline), official_disposition: open_after_review (released by DOE through formal review).
The PANTEX file specifically (DOE-UAP-D001) would arguably score higher if the released summary detailed what the ground-radar enhancement showed - that would shift sensor_quality off eyewitness_only. As released, the summary references the imagery but does not characterize it, so the rubric scores it as the document type it is on the surface.
How to verify everything on this page
- Each of the three files links above to its dedicated page on this site, with the released summary, the war.gov source URL, and the SHA-256 verification.
- The released-summary text quoted in the file cards is reproduced from the war.gov-published metadata. The Pajarito file's "not officially hosted by Los Alamos" and "no record of the subject matter" language is verbatim from the released summary.
- The historical context on PANTEX (final-assembly plant near Amarillo), Los Alamos (on the Pajarito Plateau), and James Tuck (Manhattan Project, post-war Los Alamos physicist) is standard publicly-known biographical and geographic record, not anything this site has interpreted from the released files. Where the released file metadata is silent, this site is silent too.

Bottom line
The three DOE PURSUE files are real federal records that document U.S. nuclear-weapons-complex personnel and infrastructure engaging with UAP - through a PANTEX incident report, through Los Alamos physicist James Tuck's personal correspondence, and through a Los Alamos-affiliated physicist's 1986 invited UFO talk to a civilian astronomy club. The releases are honest about scope. The PANTEX file is the most concrete; the Tuck correspondence is explicitly personal; and the Pajarito invitation comes with DOE's own framing that the event was not officially hosted by Los Alamos and that the laboratory has no record of what was discussed. Those framings are released-metadata language, not site interpretation, and they are the correct framings to keep.
