PURSUE Release 04: A UFO Put a Nuclear-Weapons Plant on Lockdown

The fourth PURSUE tranche arrived on July 10, 2026: 40 files, split as 14 documents, 19 videos, 4 audio recordings and 3 images, pulled from five agencies, the Pentagon, NASA, the CIA, the FBI and the Department of Energy. The Department of War announced it through Chief Pentagon Spokesman Sean Parnell, and Secretary of War Pete Hegseth framed it as the administration bringing “unprecedented transparency.”

Most of the coverage led with the oldest and the strangest items: a 1949 physics conference and a set of 1996 space-shuttle photographs. Those are worth a look. But the file that actually deserves the headline is duller on the surface and heavier underneath. It is a Department of Energy incident report, and it is about a night a nuclear-weapons plant went on lockdown because of something nobody could identify.

The Pantex file

The document is designated DOE-UAP-D005, titled “Pantex Unidentified Object Incident Report, 2015.” Pantex, near Amarillo, Texas, is the United States’ primary facility for assembling and disassembling nuclear weapons. It is not a place where “we don’t know what that was” is a comfortable sentence.

According to the report, in September 2015 ground surveillance radar detected an object over the site. The facility went to lockdown, and security responders acted under an approved plan for handling unmanned aerial systems. Two officers pursued the object by vehicle. They could not catch it. The detail that has carried the story is what they did next, quoted directly from the file by CBS News:

Although they were unable to catch up to the object, they stopped their vehicle and got out. Once outside, they noted that the object did not make any sound. Furthermore, the [officers] stated that they were unable to identify any type of propulsion system on the object while using binoculars to assess the object. After viewing it for 1-2 minutes, the object then continued north offsite.

Statements, video and other evidence were turned over to the FBI. The report does not identify the object, and the government files it as unresolved.

What makes this one land is not a shape or a maneuver. It is the setting. Radar-confirmed, at a nuclear-weapons facility, with an approved response plan already on the books, meaning this was not the first time the site had thought about aerial intrusions. The file does not say it was extraterrestrial. It says trained responders looked at it through binoculars and could not tell you what moved it.

The rest of the tranche

Two 2025 Navy encounters. Release 04 includes DOW-UAP-PR104, an unresolved report over the Yellow Sea, and DOW-UAP-PR105, over the East China Sea. The Yellow Sea clip drew the most attention for what the government described as “an area of contrast resembling a six-pointed star.” That phrase did a lot of work in the coverage, and it is worth being careful with it: the official wording describes an area of contrast that resembles a star shape, not an object that is star-shaped. Avi Loeb, the astrophysicist now chairing the White House UAP Science Advisory Council, argues the shape is a camera diffraction artifact, an optical effect, not the object’s true form.

A 1949 conference on “green fireballs.” DOE-UAP-D004 is a record from a 1949 Los Alamos conference where scientists tried and failed to explain the green fireballs then being seen over New Mexico. CBS quotes an astronomer at the meeting noting that “nothing like this… has ever been observed in the case of meteorite drops.” The attendees reached no consensus. It is a reminder that the government’s inability to explain an aerial phenomenon is not new, and neither is its habit of writing that down and filing it.

Three 1996 shuttle images. NASA-UAP-D030, D031 and D032 are three images of an unidentified object captured during mission STS-80 aboard the shuttle Columbia, between November 19 and December 7, 1996. Here again the council chair reaches for the mundane: Loeb assesses the object as most likely a fragment of orbital debris, one of roughly 40,000 tracked pieces larger than ten centimeters, rather than anything exotic.

The skeptic is inside the tent now

The most interesting thing about Release 04 is not in the files. It is that the person offering the deflationary read on them, diffraction artifact, space debris, no extraordinary claim required, is the sitting chair of the government’s own UAP science council. When the official science lead’s public commentary is more cautious than the tabloid headlines, the disclosure process has reached an unusual place. That is a good thing for anyone who wants the record kept honestly, and it is worth watching whether that caution survives contact with the files the government has not released yet.

None of this makes the Pantex report less serious. A prosaic explanation may well exist for what two officers watched leave a nuclear facility in 2015; the file simply does not contain one. “Unresolved” is the honest label, and it is the whole point of PURSUE: not a government admitting it has aliens, but a government publishing the cases where its own answer is still a blank. This is one of the less blank-looking blanks.
