Department of Energy UAP Records — Pantex, Los Alamos, Sandia
The U.S. Department of Energy's declassified UAP record concentrates on the nuclear-weapons complex: Pantex Plant radar imagery (DOC-138), James Tuck Los Alamos correspondence (DOC-139), and the 1986 Pajarito Astronomers Club invitation (DOC-140) — all released under PURSUE Release 02 on May 22, 2026.
The U.S. Department of Energy (DOE) — the federal agency responsible for the nuclear-weapons stockpile, the National Nuclear Security Administration, and the national laboratories at Los Alamos, Sandia, and Livermore — joined the Pentagon's PURSUE program in Release 02 on May 22, 2026 with three previously-classified records tied to the U.S. nuclear-weapons handling complex. DOE-UAP-D001 (UAP.WATCH ID DOC-138) is a Pantex Plant ground-radar imagery report from the National Nuclear Security Administration's primary nuclear-weapons assembly and disassembly facility in Texas. DOE-UAP-D002 (DOC-139) is four pages of 1970-era correspondence to and from Dr. James L. Tuck, a Manhattan Project veteran at Los Alamos National Laboratory. DOE-UAP-D003 (DOC-140) is the 1986 Pajarito Astronomers Club invitation to Dr. John Warren of LANL's AT-6 division. All three concentrate on UAP activity near U.S. nuclear-handling facilities.
“Recipe that was used for the simulated atomic bomb demonstrations.”
DOC-138: Pantex Plant ground-radar imagery
DOE-UAP-D001 is a Pantex Plant ground-radar imagery report. Pantex, located 17 miles northeast of Amarillo, Texas, is the U.S. National Nuclear Security Administration's primary facility for assembling and disassembling nuclear weapons in the active stockpile. The PURSUE Release 02 entry catalogs Pantex ground-radar captures of unidentified objects near the facility, with redactions consistent with the (b)(1) national-security classification marker.
DOC-139: James Tuck Los Alamos correspondence
Dr. James L. Tuck was a British-American physicist who worked on the Manhattan Project at Los Alamos and led ball-lightning research at Los Alamos National Laboratory. DOC-139 contains three letters: a handwritten 1970 eyewitness account to Tuck describing 'green lights weaving in and out of Mountain peaks' over Los Alamos and the Jemez Mountains during 1948-1951, all reported to the LANL Protective Force; Tuck's typed December 16, 1970 letter to the U.S. Army Engineering School at Fort Belvoir requesting 'the recipe that was used for the simulated atomic bomb demonstrations' to study atmospheric vortices per the Condon Report; and an undated note enclosing UFO researcher James M. McCampbell's commentary on ball lightning.
DOC-140: 1986 Pajarito Astronomers Club invitation
DOE-UAP-D003 is a one-page declassification of a 1986 invitation issued by the Pajarito Astronomers Club of Los Alamos. The invitation announces a May 8, 1986 talk by Dr. John Warren of Los Alamos National Laboratory's AT-6 (Accelerator Technology) division, titled 'Why Should a Scientist be Concerned about UFO's?' The full talk title is readable from the PDF but truncated in the war.gov CSV.
DOE's UAP-near-nuclear concentration
All three DOE records released under PURSUE concentrate on UAP activity near U.S. nuclear-handling facilities — a thematic concentration that mirrors the 1948-1950 Sandia Base green-fireball phenomena documented in the 116-page DOC-141 USAF bundle. The DOE record is small in volume (three records, 70MB total) but historically dense, tying mainstream nuclear physics to the early UFO investigation record.
