Pantex Facility UAP Incident
Silent diamond-shaped object tracked by ground surveillance radar and security personnel at U.S. nuclear weapons facility near Amarillo, Texas.
The Sighting
On September 1, 2015, at approximately 0710 hours, the Pantex Ground Surveillance Radar (GSR) system detected an unidentified flying object traveling west of the facility in a northerly trajectory. The Pantex Plant is a Department of Energy nuclear weapons assembly and disassembly facility near Amarillo, Texas, operated by Consolidated Nuclear Security.
Object Description
The object was described by eyewitnesses as approximately 2 feet high and 4 feet wide with a diamond-shaped configuration, more rounded at the top. Most notably, the object produced no audible sound, and security personnel using binoculars could not identify any visible propulsion system or conventional design features.
Response and Investigation
Two Pantex police force members attempted to intercept the object as it passed over Pantex Drive but were unable to catch up. Security officers tracked the object with cameras for three to five minutes as it flew at an altitude of approximately 100–200 feet above ground level. The incident was documented with statements, video, and photographic evidence, which were subsequently turned over to the FBI for investigation. Sandia National Laboratories, a Department of Energy research facility, later provided enhanced imagery of the object as part of the official analysis.
Declassification and Significance
The Pantex incident remained classified until July 2026, when it was declassified and released as part of President Donald J. Trump's directive for expedited review and public release of UAP-related government records. It appeared in the fourth official UAP data release by the U.S. Department of War, notable for involving radar confirmation at a sensitive nuclear weapons facility with multiple corroborating witness accounts and official government investigation records.
Witnesses
Multiple Pantex security personnel, including two police force members who attempted intercept; facility staff with binocular observations.
Evidence
Ground Surveillance Radar (GSR) detection data, multiple eyewitness testimonies, video recordings tracked over 3–5 minutes, photographic evidence, enhanced imagery from Sandia National Laboratories, official incident report filed with FBI.
