The Silent Diamond at Pantex

It made no sound. A Protective Force lieutenant and a security police officer had tried to get beneath the object as it crossed Pantex Drive. When they stopped and got out they heard nothing, the report says. Through binoculars they could not identify "any type of propulsion system". They watched it for a minute or two and then followed it for several miles north of the plant. It "seemed to increase in speed and changed direction as it was being followed", heading off to the east-north-east before they lost it near County Road G and F.M. 1342.

Ground surveillance radar had found it at about 07:10 south-west of the plant's buildings, moving north at 10 to 15 mph. Every gate into the security areas was locked. Officers in an armoured Bearcat held it on their CROWS camera for three to five minutes at 100 to 200 feet. The pursuing pair called it "diamond" shaped and rounder at the top. Another officer put it at about four feet tall and two feet wide. Some saw it as black. Others saw silver, red and blue.

What is on the record

The record is the plant's own "Pantex Unidentified Object Incident Report", sent to the National Nuclear Security Administration on 9 September 2015 and released by the Department of War on 10 July 2026 as DOE-UAP-D005. Two image pages had appeared in May as DOE-UAP-D001. The report was already public in part: The Black Vault obtained a less redacted copy through a freedom of information request in July 2025.

The report dates the sighting to 1 September in its narrative but to 2 September on its title page and cover letter. Tower video went to Sandia National Laboratories, and the report admits it "does not provide much detail". A Carson County deputy joined the search but did not see the object. All evidence went to the FBI. The plant responded under its drone plan, but nothing released identifies the object. Metabunk forum members have likened the Sandia image to a coaxial drone.

Why it sits where it does

L4 · OFFICIAL RECORD — a released government record names who saw it. The observers are Pantex Protective Force officers on duty, identified by role with their names withheld. No independent testimony sits beside the report in the archive, and the tier measures sourcing rather than truth. What crossed the plant is not resolved here.
