Washington — The Pentagon released 40 new files related to unidentified anomalous phenomena, or UAPs, including a report from a military aviator who described one object as unlike anything he had encountered during 28 years of service.

The release includes 14 documents, 19 videos, four audio files and three images. The material was collected from several federal agencies, including the Pentagon, NASA, the CIA, the FBI and the Department of Energy.

The files were published on the Pentagon’s UAP website as part of a broader disclosure effort ordered by President Donald Trump earlier this year.

Unidentified Object Reported Near Nuclear Facility

One of the most significant reports describes an unidentified object entering restricted airspace near the Pantex nuclear weapons facility outside Amarillo, Texas, in September 2015.

According to the Department of Energy document, the facility was placed on lockdown while two officers attempted to follow the object.

The officers were unable to catch it and eventually stopped their vehicle to observe it with binoculars. They reported that the object produced no sound and showed no visible propulsion system.

After remaining visible for approximately one to two minutes, the object continued north and left the facility’s airspace.

Military Videos Show Unexplained Objects

Approximately half of the newly released files document incidents from 2010 or later. Several include infrared footage recorded by military sensors over the Atlantic Ocean, the western Pacific and the Middle East.

One report describes a 2020 encounter over the Atlantic involving an object that appeared dark maroon and measured an estimated 12 to 15 feet in height.

A Navy weapons systems officer said the object resembled a large, irregularly shaped balloon, although the crew could not confirm its identity before passing it.

The incident was documented in a “range fouler debrief,” a standardized Navy report used to record unauthorized objects or aircraft entering controlled military airspace during operations or training.

Aviator Reports Object Moving at High Speed

Another report documents a 2019 incident over the eastern United States. The object was observed by an experienced military aviator and four additional personnel.

The aviator reported seeing a small object traveling in a straight line at high speed in the opposite direction of the aircraft.

He tracked it for approximately 10 to 15 seconds before recording the encounter. When he increased the camera’s zoom, the object quickly moved out of view and could not be located again.

A later review of the footage suggested that the object may have been rectangular. Other experienced personnel who reviewed the incident were also unable to identify it.

The aviator wrote that the object displayed flight characteristics unlike anything he had seen during nearly three decades of service with the Air Force and Navy.

Recent Incidents Near China

The newest incidents included in the release occurred in 2025 within the U.S. Indo-Pacific Command’s area of responsibility.

One video shows a military sensor tracking an object or area of contrast resembling a six-pointed star over the Yellow Sea. Another records an unidentified object being tracked for several minutes over the East China Sea.

The available footage does not provide enough information to determine what the objects were.

Historical Records Include “Green Fireball” Investigation

The release also includes historical records, including a transcript from a 1949 conference in Los Alamos, New Mexico.

Scientists and physicists, including individuals connected to the Manhattan Project, met to discuss reports of unexplained green fireballs observed near the Los Alamos nuclear laboratory.

Some participants suggested that the objects may have been meteors entering the atmosphere. However, one astronomer noted that the reported behavior did not match known meteorite events.

The conference did not reach a definitive explanation.

Additional Files Expected

The Pentagon said the latest release is not the final disclosure planned under the executive order.

Officials said the department and its partner agencies are continuing to review UAP records and prepare additional files for public release.
