DOE-UAP-D001 is a Department of Energy record documenting an unidentified-object detection at the Pantex Plant in the Texas Panhandle. The record was released in PURSUE Release 02 on May 22, 2026, by the Department of War. No incident date or specific geographic coordinates within the facility are recorded in the released material.12
Provenance and Chain of Custody
DOE-UAP-D001 originates from the Pantex Plant, operated by Consolidated Nuclear Security, LLC, and administered under the Department of Energy. Pantex is the United States' primary nuclear-weapons assembly, disassembly, and maintenance facility. Its location in the Texas Panhandle places it among the most security-sensitive installations in the country, and the facility maintains its own ground-based surveillance infrastructure independent of standard military air-defense channels.
The record was not generated by a military radar installation or an aviation safety authority. Instead, it emerged from Pantex's internal surveillance reporting apparatus -- the kind of system maintained to monitor the immediate perimeter and airspace of a nuclear-weapons site. The document carries UCNI (Unclassified Controlled Nuclear Information) markings throughout, which reflects both the nuclear security context and the controlled nature of the information presented. UCNI is a category of information that is unclassified but restricted from public disclosure under the Atomic Energy Act due to its sensitivity to nuclear security.
The release of this record through the Department of War's PURSUE program marks its first public disclosure. No prior FOIA releases of this specific document are referenced in the available record.3
What the Document Contains
The released pages present two categories of imagery derived from the incident: original ground surveillance radar tower imagery, and enhanced images processed by Sandia National Laboratories.
The radar scope display captures a small unidentified object marked with a red circle in the upper right portion of the radar presentation. A large portion of the radar tower image display is redacted under FOIA exemption (b)(3) and UCNI protections, indicating that information withheld may relate to sensitive facility security procedures or technical details about detection capabilities or site vulnerabilities.
Sandia National Laboratories -- a federally funded research and development center operated under the Department of Energy that provides technical support across nuclear security and national security programs -- produced two enhanced images from the original surveillance data:
The upper enhanced image shows a dark object with an irregular, somewhat triangular or multi-lobed shape. The object is surrounded by a blue or cyan thermal halo or glow effect at its perimeter, consistent with processing of thermal or infrared sensor data.
The lower enhanced image shows a smaller, more compact dark circular or oval object exhibiting similar thermal coloration and a characteristic halo effect around its edges.
Both images reflect characteristics consistent with infrared or thermal sensor data processing techniques. The imaging modality is not described explicitly in the released text, but the thermal halo and coloration patterns in both stills are visually consistent with forward-looking infrared or similar sensor output.
The document does not include measurements, object dimensions, precise altitude or range estimates, timing data, or any analytical conclusion regarding the identity or origin of the detected object. It records only what the surveillance systems captured.
Significance of the Referral to Sandia
The escalation from an initial radar detection at a facility security post to technical image enhancement at Sandia National Laboratories is notable. Sandia is not a routine recipient of routine security anomalies; it is a national laboratory with deep expertise in nuclear weapons physics, advanced sensing, and intelligence analysis. Its involvement implies that the Pantex security chain of command considered the detection sufficiently anomalous -- in terms of object characteristics, behavior, or radar return -- to warrant expert technical review rather than dismissal as noise or known traffic.
The released record does not explain what specific characteristics drove the referral, what Sandia's analysts concluded after examining the enhanced imagery, or whether any follow-up investigation was conducted. The absence of a conclusions section or accompanying analytical memorandum within the released pages limits what can be directly inferred from the document.
Classification and Redaction Pattern
The use of UCNI markings throughout, combined with (b)(3) redactions covering substantial portions of the radar tower image display, indicates that information has been withheld beyond what UCNI alone would require. FOIA exemption (b)(3) applies to material specifically exempt from disclosure by statute; in a nuclear facility context, this exemption is frequently applied to restrict information that could reveal vulnerabilities in nuclear facility security or the technical parameters of detection systems. The redaction pattern therefore signals that the full radar presentation -- possibly including sweep parameters, detection geometry, or object track data -- was deemed too sensitive for release.
The enhanced Sandia imagery itself appears to have been released without additional redaction, though the accompanying analysis or conclusions, if any, are not present in the released pages.
Key Entities
The record involves three principal entities. The Department of Energy is the releasing agency and the parent department for the Pantex facility. Consolidated Nuclear Security, LLC is the operating contractor responsible for running Pantex on behalf of the Department of Energy. Sandia National Laboratories is the technical entity that performed image enhancement; it is managed and operated for the Department of Energy by National Technology and Engineering Solutions of Sandia, a wholly owned subsidiary of Honeywell International.
No named individuals appear in the released material. No incident report number beyond the document identifier DOE-UAP-D001 is provided.
What The Record Supports
This document establishes that an unidentified object was detected by ground surveillance radar at the Pantex Plant -- the United States' primary nuclear-weapons facility -- and that the detection was significant enough to prompt referral for technical image enhancement at Sandia National Laboratories. The enhanced imagery produced by Sandia shows a dark object with thermal or infrared characteristics in two distinct still captures.
The record does not establish the identity, origin, altitude, speed, or dimensions of the object. It does not contain a security assessment or determination of whether the object posed a threat to the facility. It does not contain analytical conclusions from Sandia or any other authority. Substantial portions of the underlying radar data remain redacted under UCNI and statutory FOIA exemptions.
The object remains unidentified. The record supports no extraordinary explanation, but it does document that a formal surveillance detection at a nuclear-weapons site generated enough uncertainty to be escalated for expert technical review and retained for eventual declassification and release.
