Case No. 293·United States
1976–2024·DOE nuclear complex — Los Alamos and Sandia (NM), Pantex (TX)
United States.DOE · UAP records from the nuclear complex (Pantex, Los Alamos — PURSUE R02)
Three Department of Energy documents declassified in PURSUE Release 02 (May 22, 2026) share a thread: sustained interest in UAP within the U.S. nuclear-weapons complex. DOE-UAP-D001 is a 'Pantex Unidentified Object Incident Report' (marked UCNI) about the country's sole nuclear-weapons assembly/disassembly plant, with an image captured from a ground surveillance radar tower and enhanced by Sandia National Labs. DOE-UAP-D002 is 1970s correspondence of Los Alamos physicist James L. Tuck (Manhattan Project; later controlled fusion) about anomalous phenomena, ball lightning and the Condon Report. DOE-UAP-D003 is a 1986 invitation from the Pajarito Astronomers of Los Alamos to a talk by physicist Dr. John Warren (LANL) titled 'Why Should a Scientist be Concerned about UFO's?'. Their value is institutional context —they document decades of attention to the phenomenon inside the nuclear apparatus, not that the objects were anomalous.

Limited evidence: single-witness, local or without primary verification. Three independent axes: the «tier» measures the strength of the evidence; the «probability» estimates how genuinely unexplained the case is —a natural phenomenon can remain unexplained, so it does not equal «non-prosaic»—; and the partition of explanations (below) says what it most plausibly was. So a well-documented case can have a possible hoax as its most plausible cause, and a Tier B is not, for that reason, a hoax.

The file in question
PURSUE Release 02 (May 22, 2026) was mostly audiovisual material, but it included six PDF documents. Three of them come from the Department of Energy (DOE) and share a thread rarely documented with primary sources: sustained interest in anomalous phenomena within the U.S. nuclear-weapons complex and its national laboratories. They are heterogeneous in form and weight, but coherent in theme.
DOE-UAP-D001 — 'Pantex Unidentified Object Incident Report'. Pantex, near Amarillo (Texas), is the country's sole plant for the final assembly and disassembly of nuclear weapons, operated by Consolidated Nuclear Security, LLC. The released extract (two pages, marked UCNI — Unclassified Controlled Nuclear Information, pages 5-6 of a 6-page report) contains an image captured from a ground surveillance radar tower at the site and, on the next page, 'Sandia National Labs Enhanced Images of the Object'. That is: an unidentified object over the most sensitive nuclear-weapons facility in the country, documented by site security and with the image enhanced by Sandia. The continuity with the historical pattern of UAP over nuclear infrastructure —the Sandia/Los Alamos green fireballs of 1948-49, Malmstrom in 1967— is direct.
DOE-UAP-D002 — correspondence to and from James L. Tuck, a British-American Los Alamos physicist (he worked on the Manhattan Project's explosive lenses and later led the Project Sherwood controlled-fusion effort). The 1970s letters show his personal interest in the anomalous: he discusses ball lightning, mentions the Condon Report (Dr. Edward U. Condon), cites James M. McCampbell's book 'UFOLOGY' (1976), and speculates about Einstein's unified field theory and propulsion. Tuck is a through-line: he had taken part in the New Mexico green-fireball investigations around 1949 alongside Lincoln La Paz, so his 1970s correspondence extends a decades-long Los Alamos engagement with the question.
DOE-UAP-D003 — a one-page invitation, dated May 20, 1986, from the Pajarito Astronomers, the Los Alamos amateur-astronomy club, to its May 29, 1986 meeting in the Ranch Room at Fuller Lodge. The guest speaker was LANL physicist Dr. John Warren (division AT-6), with the talk 'Why Should a Scientist be Concerned about UFO's?'. It is the most tangential of the three —a club talk, not an incident— but it documents that the question was circulating inside the Los Alamos scientific community.
All three are embedded in the case viewer as self-hosted PDFs (same-origin), with a link to the official war.gov original: since war.gov blocks third-party framing, the embeddable binary was obtained from a public mirror and is served from the repo.

Why this case moved the needle
The value of these three documents is institutional context, not evidence. None proves an anomalous origin: the Pantex extract is redacted and trimmed to two pages with no kinematic data or published chain of custody; Tuck's correspondence is a scientist's personal interest, not an official investigation; and the Pajarito Astronomers invitation is, literally, the announcement of a club talk. Taken separately, they are minor pieces.
Taken together, however, they document with primary sources a fact often asserted and seldom cited: that the U.S. nuclear-weapons complex —the DOE and its labs, Los Alamos, Sandia, Pantex— has engaged with the UAP question across decades, from the green-fireball era to a contemporary security incident at Pantex. The Pantex report is the most substantive (security-grade documentation + Sandia image enhancement over a top-tier nuclear site); the Tuck and Pajarito pieces are softer evidence of sustained scientific attention. The calibrated reading: these are records of attention, not of anomaly —but they fill a provenance gap, anchoring the 'UAP over nuclear facilities' pattern to primary DOE documents released by PURSUE.

What's left on paper
Documented evidence
- DOE-UAP-D001 — 'Pantex Unidentified Object Incident Report' (UCNI), image from a ground surveillance radar tower + 'Sandia National Labs Enhanced Images of the Object'; Pantex is the sole U.S. nuclear-weapons assembly plant
- DOE-UAP-D002 — 1970s correspondence of Los Alamos physicist James L. Tuck on ball lightning, the Condon Report and 'UFOLOGY' (McCampbell, 1976); Tuck took part in the 1949 green-fireball investigations
- DOE-UAP-D003 — invitation (May 20, 1986) from the Pajarito Astronomers of Los Alamos to a talk by Dr. John Warren (LANL, AT-6): 'Why Should a Scientist be Concerned about UFO's?' (May 29, 1986, Fuller Lodge)
