UFO files release 4, July 10, 2026

The fourth batch of government UFO files, published on July 10, 2026. It includes a 1949 transcript on the green fireballs seen over Los Alamos.

The short answer

Release 4 of the UFO files came out on July 10, 2026. The Department of War published it at war.gov/UFO. CBS News counted 40 files: 14 documents, 19 videos, 4 audio files and 3 images, from the Pentagon, NASA, the CIA, the FBI and the Energy Department. Nothing in the release says any object was non-human.

The oldest headline item is a 1949 scientific conference transcript. The newest are 2025 military sensor tracks over the Yellow Sea and the East China Sea. Every release also sits in the Disclosure Ledger, and the program is set out on the PURSUE files page.

What the department said

Sean Parnell’s statement confirmed the fourth release and said the department and its agency partners were “actively working on the next release of UAP files.” It made no claim about the contents. The descriptions below come from CBS News, which reviewed the batch on the day it was posted.

What was in release 4

These are the files news outlets singled out on the day. They are a sample, not the whole batch, and the descriptions are the outlets’ summaries of the records.

A 1949 transcript of a Los Alamos conference on the “green fireballs” seen near the nuclear laboratory, attended by leading scientists including Manhattan Project veterans (CBS News).
September 2015, the Pantex nuclear weapons plant near Amarillo, Texas: officers reported an object that made “no sound” and said they could not identify any propulsion system (CBS News).
2020, Atlantic Ocean: a maroonish object about 12 to 15 feet tall that a crew said looked like a large, deformed balloon, which they could not confirm (CBS News).
2019, eastern United States: an aviator describing a fast rectangular object with flight characteristics unlike anything in 28 years of service (CBS News).
2025: a military sensor track over the Yellow Sea resembling a six-pointed star, and an object tracked for several minutes over the East China Sea (CBS News).

Exhibit · Release 4 claim checked

The claim, checked

The line about this release that travels furthest, set against what the record supports.

FALSE AS WORDED
“Los Alamos scientists concluded the green fireballs were alien.”
What the record shows
According to CBS News, the 1949 conference failed to explain the fireballs. One theory put forward was meteors, and a prominent astronomer said nothing like them had been seen in meteorite falls. That is a record of scientists who could not explain something. It is not a conclusion that it was alien, and the coverage we read reports no such conclusion.

Reading release 4

This release shows why the incident date matters more than the release date. A 1949 transcript and a 2025 sensor track arrived in the same batch, from different agencies, collected for different reasons.

It also shows how often the witnesses themselves reach for ordinary words. The 2020 Atlantic crew said their object looked like a balloon. When a file records a doubt, keep the doubt when you retell it.

What it does not show

It does not show an explanation for any of its headline cases, and it does not show a finding that any of them was non-human. Every case CBS News described from this batch remains unresolved. For the claims made about all six releases together, read did the UFO files confirm aliens?

Sources

File counts are news tallies, credited to the outlet that made them. The department’s own pages were read through a mirror of its release text and a copy of war.gov/UFO, because war.gov blocked direct requests.
