A disc-shaped object reportedly hovered over the Pantex nuclear weapons assembly plant in Texas, according to a Department of Energy incident file now publicly accessible through the Pentagon’s rolling declassification of unidentified anomalous phenomena records. The file, designated DOE-UAP-D005, appeared in the second tranche of documents released on May 22, 2026, as part of a government-wide effort known as PURSUE. The record places the sighting near active weapons storage areas, raising pointed questions about whether existing nuclear-site security sensors captured anything during the same window.
A disc over Pantex and why the timing matters
The Pantex Plant, operated under the National Nuclear Security Administration near Amarillo, Texas, is the only facility in the United States that assembles and disassembles nuclear warheads. Any unidentified object lingering above its perimeter carries immediate national security weight, regardless of its origin. DOE-UAP-D005 describes a metallic disc that remained stationary for several minutes before departing at high speed. The incident reportedly took place in 2015, but the file stayed out of public view for more than a decade until the second PURSUE tranche brought it into the open.
PURSUE is a government-wide effort to collect, review, and publish UAP-related records across federal agencies. Materials are released in tranches on a rolling basis, meaning each batch can surface files from different agencies and different decades. The May 22, 2026 release is where the Pantex disc file appeared, grouped with unrelated sightings from other locations and years. The Department of War has stated that additional files will follow on a rolling basis after that date, so DOE-UAP-D005 may ultimately be joined by supporting documents or contextual memoranda that are not yet available.
The practical test for this file is straightforward. The NNSA maintains shift logs, guard-post records, and sensor data at Pantex. If the timestamps in DOE-UAP-D005 overlap with any corroborating radar return, camera capture, or security-post notation in unclassified NNSA records, the disc report gains a second leg of evidence. If no matching sensor data exists, the file remains a single-source account. The agency’s own frequently requested records list Pantex security documentation among its recurring FOIA targets, but no direct excerpts tied to this specific 2015 incident have been published so far.
What the PURSUE files and AARO’s position actually show
The official portal for these records is hosted at WAR.GOV/UFO. The Department of War launched the site with participation from the Office of the Director of National Intelligence, the Department of Energy, the All-domain Anomaly Resolution Office, NASA, and the FBI, according to the department’s own announcement of the initial transparency effort. That interagency roster matters because it means DOE files like the Pantex report pass through a coordinated review process before publication, not a single agency acting alone.
AARO, the Pentagon office responsible for investigating UAP reports, has maintained a clear institutional position: it has found no substantiated signs of extraterrestrial activity or off-world technology in the cases it has evaluated. That statement applies broadly to all sightings the office has reviewed, not specifically to the Pantex case. No public AARO assessment addresses DOE-UAP-D005 by file number, date, or location. The gap between a general institutional finding and a case-specific analysis is where the tension sits. AARO’s blanket conclusion does not tell readers whether analysts examined the Pantex disc report individually or grouped it into a statistical batch that produced no actionable leads.
The documents released through PURSUE so far do not include interagency correspondence between DOE and AARO about this incident. Without that paper trail, it is unclear whether AARO requested sensor data from Pantex, whether DOE flagged the sighting for follow-up, or whether the file sat dormant in a classified archive until the declassification mandate forced it into the public queue. The absence of that context leaves the public with a bare-bones description of the object and its proximity to nuclear infrastructure, but little insight into how seriously internal reviewers treated the event.
That ambiguity extends to classification levels. DOE-UAP-D005 appears in the PURSUE index as a discrete record, but the portal does not specify whether portions of the original report remain redacted. Nuclear-site security documentation is typically compartmented, and it is possible that any detailed discussion of sensors, response protocols, or facility schematics was withheld even as the basic narrative of the disc was released. If so, what the public sees now may be only a sliver of a more extensive internal file.
Sensor gaps and the next files to watch
Several concrete questions remain open. The full PDF text of DOE-UAP-D005 is referenced on the PURSUE landing pages, but no complete primary document with the original sensor descriptions, witness statements, or technical measurements has been independently hosted or quoted in the official press releases accompanying the second tranche. Readers and researchers working from the portal can see that the file exists and that it describes a disc near weapons storage, but the granular detail needed to evaluate the claim, such as altitude, radar cross-section, or duration down to the second, has not been confirmed in publicly available excerpts.
The NNSA’s documentation practices add another layer of difficulty. Pantex security logs are among the most frequently requested records through the agency’s FOIA process, yet the agency provides no direct links or excerpts tied to the 2015 disc incident. That means independent verification currently depends on filing new FOIA requests and waiting for processing, a timeline that can stretch months or years for records involving nuclear facilities. Until at least one such request yields responsive, unredacted material, the Pantex disc will remain largely a matter of trust in the DOE summary rather than a fully reconstructable event.
The Department of War has signaled that more files will follow. Future tranches could include the interagency correspondence, sensor data, or AARO case notes that are missing today. If those materials surface, they would help answer several basic questions: whether the disc was tracked on any government radar; whether it triggered an elevated security posture at Pantex; whether any aircraft were scrambled; and whether investigators ultimately judged it to be a misidentified conventional object, a sensor artifact, or something still unexplained.
For now, DOE-UAP-D005 occupies an awkward middle ground. It is more concrete than rumor, because it is anchored in an official incident file released through a structured declassification program. Yet it is less informative than a full case study, because the underlying data, imagery, and analytic conclusions remain out of sight. As PURSUE continues, the Pantex disc will serve as a test of how far the government is willing-or able-to go in documenting unexplained events that intersect with the most sensitive corners of the U.S. nuclear enterprise.
