The Pantex Plant UFO Incident

The Pantex Plant UFO incident refers to a September 2015 encounter at the Pantex nuclear weapons facility near Amarillo, Texas, in which security personnel tracked a diamond-shaped unidentified object by ground surveillance radar, photographed it, and sent the images to Sandia National Laboratories for analysis. A partial declassification in May 2026 released two pages of the six-page incident report — including the radar image and Sandia's enhanced photographs. The conclusions from that analysis remain classified.

The Pantex Plant doesn't appear in many news stories. That's largely by design. It sits on the flat plains of the Texas panhandle, visible from miles away but reachable only through multiple security checkpoints. Officially, it assembles and disassembles U.S. nuclear warheads. Unofficially, it is the most nuclear-sensitive piece of real estate in America — every warhead that enters or leaves the U.S. nuclear arsenal passes through there.

On the morning of 22 May 2026, the Department of War published its second batch of declassified UAP documents. Buried among diplomatic cables and Cold War intelligence reports was a two-page partial release from the Department of Energy: DOE-UAP-D001, labelled "ENHANCED PANTEX IMAGERY." It showed a ground surveillance radar image with an object circled, and two Sandia National Laboratories enhanced photographs of something dark, solid, and unidentified in the sky above the facility. Almost everything that might explain what the object was — or wasn't — had been blacked out.

What Is the Pantex Plant?

Pantex was built in 1942 as a conventional bomb plant to support the Second World War. After the war it was mothballed, then reactivated in 1951 at the start of the nuclear arms race. Since then it has been the single point through which all U.S. nuclear warheads pass — whether being assembled for deployment, maintained, or dismantled under arms reduction treaties.

The plant covers roughly 16,000 acres in Carson County, about 15 miles northeast of Amarillo. It is managed by Consolidated Nuclear Security, LLC — a subsidiary of BWX Technologies — under contract to the U.S. Department of Energy. At any given time, Pantex holds a significant portion of the American nuclear arsenal, making it one of the most comprehensively monitored and defended sites in the country. It has its own security force, its own radar systems, and strict protocols for anything that enters its restricted airspace.

The fact that a UFO was tracked over this facility — and that the government chose to release images of it, however redacted — matters. This isn't a sighting near a generic military base. It's a sighting at the place where America assembles and stores its nuclear weapons.

The September 2015 Incident: What the Report Says

The incident report itself was first obtained by journalist Dustin Slaughter of the UAP Register through a Freedom of Information Act request, published in June 2024. The May 2026 declassification released an enhanced version of the imagery.

According to the document, Pantex security personnel were alerted to an unidentified object on 2 September 2015. The object was described as having a "diamond type-shape with it being more round at the top." Personnel were then directed to follow the object and gather as much information as they could.

The object continued travelling north of the facility. Security tracked it for several miles before it was, in the report's words, "no longer visible." It didn't land. It didn't turn around. It simply disappeared from view.

Crucially, the sighting wasn't only visual. The object was picked up by ground surveillance radar — the same systems that monitor the facility's restricted airspace around the clock. It was also photographed from a nearby radar tower, believed to be located at or near Rick Husband Amarillo International Airport. Those photographs were subsequently sent to Sandia National Laboratories for enhancement and analysis.

What the Declassified Images Actually Show

The released document (DOE-UAP-D001) contains pages 5 and 6 of a 6-page report. The first four pages — which would contain the written witness accounts and incident narrative — were not included in this release. What we have are two images.

Page 5 shows the ground surveillance radar image. It's a wide view of the area around the facility, with a small object circled in the upper-right quadrant. The descriptive text explaining what the radar return signified is fully redacted under UCNI provisions.

Page 6 shows the Sandia National Laboratories enhanced imagery — two separate captures of the object. These are more striking. The enhanced images show what appears to be a dark, solid, three-dimensional shape against the sky. It is wider at the top and narrows toward the base, consistent with the "diamond type-shape, more round at the top" described by witnesses. There is a faint haze or corona visible around its outline — possibly an artifact of the enhancement process, possibly something else. Whatever Sandia's analysts made of it, their conclusions are on pages that haven't been released.

The classification status of the released pages — UCNI, or Unclassified Controlled Nuclear Information — is itself notable. UCNI is a specific category that protects information about nuclear facility security: surveillance capabilities, response protocols, vulnerabilities. By citing UCNI as the reason for redaction, the government is signalling that the withheld information says something meaningful about Pantex's security infrastructure. Which means whatever happened there was taken seriously enough to protect.

Pantex UFO Sightings: A History Going Back to 1957

The 2015 incident isn't unusual in the context of Pantex's history. It's just the first to be formally documented in a government report that has since been released.

On the evening of 7 November 1957, plant guards at Pantex reported three disc-shaped craft with bright coloured lights hovering approximately 50 feet above the facility. The Amarillo Globe-Times covered it the next day:

The patrolman who responded said guards told him one of the objects had landed on Farin Road, three miles north of the facility. When they drove to the location, nothing was there — but the officer said he was "convinced that the guards saw something land." Guards had tried turning off their headlights to approach undetected. The report noted the objects "would just slip away from them when they got near."

Multiple former Pantex employees and local residents submitted accounts to the National UFO Reporting Center describing a pattern that continued through the late 1950s and early 1960s. The sightings were frequent enough that fighter jets from Amarillo Air Base were scrambled on multiple occasions. Two witnesses who lived within a few miles of the plant described the same behaviour repeatedly:

Another witness described approximately 100 sightings over the same period: "Always the same type of object — that changed colors." When jets closed to within two miles, the object would climb vertically and wait until the aircraft returned to base. Then it came back.

Why Do UFOs Keep Appearing Over Nuclear Weapons Facilities?

Pantex sits within a well-documented pattern. For more than 70 years, declassified records have consistently shown unusual aerial activity around nuclear weapons facilities — not isolated incidents, but repeated, documented encounters across multiple sites, multiple decades, and two superpowers.

The pattern begins as early as January 1945, when declassified FBI and Air Force records confirm reports of unusual objects over the Hanford plutonium processing plant in Washington State — before Hiroshima, before the world knew what was being built there. From December 1948, brilliant green fireballs appeared repeatedly over Los Alamos, Sandia, and Kirtland Air Force Base. In 1967, ten Minuteman nuclear missiles at Malmstrom Air Force Base went offline simultaneously while guards reported a glowing object overhead. In 1982, personnel at a Soviet missile base in Ukraine watched their launch codes briefly activate without authorisation while a sphere hovered above the facility.

AARO — the Pentagon's All-domain Anomaly Resolution Office — has formally logged at least 18 UAP reports near U.S. nuclear weapons sites. Lue Elizondo, former director of the AATIP programme, stated plainly to Congress: "There is a relationship between UAP and our nuclear equities. This has been going on for decades."

Pantex is not an anomaly in that pattern. It is the latest confirmed entry in it.

What the Declassified Pantex UFO Documents Don't Tell Us

The UAP Register has filed additional FOIA requests for Sandia's full analysis and is considering litigation to compel further disclosure. The Department of Energy has not responded to requests for comment, including whether the investigation into the Pantex incident remains open.

More releases from the PURSUE programme are expected on a rolling basis. Whether the first four pages of the Pantex report are among them remains to be seen.
