The mystery of unidentified aerial phenomena (UAP)—known to the general public as UFOs—is once again taking center stage in international news, following the release of a new batch of declassified U.S. documents that include reports of incidents near high-security military facilities and areas related to the U.S.United States.

The fourth consecutive release was posted on Friday on the U.S. Department of Defense website, accompanied by the message that “it is time for the American people to see for themselves,” thereby expanding the public record that has been established regarding UAPs.

The Incidents
Among the new materials, several military videos stand out that were recorded by infrared sensors on U.S. military platforms.

One of them, 18 seconds long, was recorded in 2025 over the Yellow Sea and shows a mysterious object with a shape described as eight-pointed or star-like hovering intermittently over East Asia.

In other footage, recorded in 2020, a dark, “jellyfish”-like object appears to be drifting across the sky over the Atlantic Ocean. According to a report from U.S. Northern Command to the All-Domain Anomaly Resolution Office (AARO), the object was approximately 12 to 15 feet tall and was moving with the wind, with analysts noting that it could even have been a large, misshapen balloon. The Department of Defense itself points out that the release of the video does not constitute an official conclusion regarding the object’s identity.

Of particular interest is a 1996 video from the Navy’s former UAP Task Force, which shows a circular object with wing-like protrusions moving over a mountainous region on the western side of the United States, while being tracked by a military aircraft.

The incident at the Pantex
nuclear complex Among the most significant documents is a report by the Department of Energy on an incident that occurred in September 2015 at the Pantex nuclearPantex Nuclear Weapons Plant in Texas, the U.S.’s primary facility for the assembly and disassembly of nuclear weapons.

According to the report, radar detected an unidentified object flying at an altitude of just 100 to 200 feet above the heavily guarded facility. The security personnel who were dispatched described it as silent, diamond-shaped, and lacking any apparent propulsion system.

The object was tracked for several miles before disappearing, and the footage was analyzed by Sandia National Laboratories; all data was forwarded to the FBI. The release includes radar tracks, surveillance images, and processed still frames from the investigation.

Footage from 2023 and 2024
The new batch of documents also includes nearly two minutes of infrared video recorded in 2024, in which an elongated object appears, after zooming in with the sensor, to split into multiple bright spots moving diagonally.

Meanwhile, a video lasting just 10 seconds from 2023 captures two unidentified objects moving simultaneously in opposite directions, with no official explanation given for their origin.

The Historical Dimension of the Declassified Documents
The disclosure is not limited to contemporary events. Among the historical records is the transcript of a secret meeting held in 1949 at Los Alamos, where military officials and leading scientists discussed the wave of sightings of so-called “green fireballs” over New Mexico, many of which had been observed near nuclear facilities.

At the meeting, astronomer Lincoln LaPaz argued that the objects did not exhibit the characteristics of conventional meteors, while it was revealed that not even the Air Force itself could explain the phenomenon.

At the same time, documents from the infamous 1948 “Project Sign”—the U.S. Air Force’s first major classified investigation into reports of “flying saucers”—were made public.

The investigators, examining approximately 100 incidents, noted significant similarities in the testimonies, with objects described as disc-shaped or oval, capable of hovering, accelerating abruptly, and, according to some reports, exceeding the speed of sound. Although they did not reach a definitive conclusion, they noted that the available evidence was substantial enough to warrant further investigation.

The COMETA Report and Hegesez’s
Statements The archive also includes the well-known COMETA Report, a study conducted by retired French generals and defense experts. The report argues that, for some of the most unexplained incidents worldwide, the hypothesis of extraterrestrial origin is one of the possible explanations, urging governments to treat the issue as a matter of national security.

For his part, U.S. Secretary of Defense Pete Hegese, stated that the department is fully cooperating with President Donald Trump to achieve “unprecedented transparency” regarding UAPs.

“These files, which remained classified for years, fueled speculation. It’s time for American citizens to see them with their own eyes,” he said.

No Definitive Conclusions
Despite the breadth of the material released, the Pentagon clarifies that most incidents are still under evaluation and that the release of the videos and documents does not constitute confirmation of extraterrestrial origin or a specific explanation for the recorded phenomena.

According to the Department of Defense, the website hosting the declassified files has already garnered more than 1.7 billion visits worldwide, a fact which, it states, reflects the unprecedented international interest in research into Unidentified Anomalous Phenomena.
