The War Department on Friday released additional declassified and historical Unidentified Anomalous Phenomena files.

The latest release, posted on the Pentagon's UAP website, includes 40 newly declassified files — 14 documents, 19 videos, four audio recordings, and three images — from the War Department, NASA, CIA, FBI and Department of Energy as part of President Donald Trump's executive order directing greater transparency on UAP-related records.

"Today, the Department of War is publishing the fourth release of declassified and historical Unidentified Anomalous Phenomena (UAP) files as part of the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE)," Pentagon spokesman Sean Parnell said in a statement on the Pentagon’s website.

He added that additional files will be released on a rolling basis.

Among the most notable disclosures is a military aviator's account of a 2019 encounter over the eastern United States.

"I noticed an object with flight characteristics unlike anything I had seen in my 28 years of performing for the [Air Force] and Navy," the aviator wrote, describing a fast-moving rectangular object that several experienced personnel were unable to identify, CBS News reported.

Another report details a 2015 incident over the Pantex nuclear weapons facility near Amarillo, Texas, where security officers pursued a silent unidentified object that appeared to lack any visible propulsion system before it disappeared from view.

The release also includes infrared videos captured over the Atlantic Ocean, the western Pacific and the Middle East.

One of the most unusual recordings, highlighted by the New York Post, shows what military analysts described as "an area of contrast resembling a six-pointed star" over the Yellow Sea near China and the Korean Peninsula.

Other files describe a jellyfish-shaped object observed over the Atlantic in 2020 that investigators said resembled a large balloon but could not positively identify.

The historical records stretch back decades, including transcripts from a 1949 conference in Los Alamos, New Mexico, where Manhattan Project scientists debated unexplained "green fireballs" repeatedly observed over the nuclear laboratory.

Researchers at the time were unable to agree on a conventional explanation.

The latest disclosure does not offer proof of extraterrestrial life, and Pentagon officials continue to stress that investigators examine possible explanations ranging from weather balloons to atmospheric phenomena and advanced foreign technology before reaching conclusions.

Trump has repeatedly expressed skepticism about alien life but also has pushed for greater government transparency on unidentified anomalous phenomena.

Earlier this year, he directed federal agencies to declassify historical UAP records after years of public demands for greater disclosure.

The Pentagon said Friday's release will not be the last, with officials confirming additional UAP files are already being prepared for publication under the administration’s transparency initiative.
