WASHINGTON — The Trump administration on Friday released a tranche of declassified documents related to Unidentified Aerial Phenomena (UAP), fulfilling a promise the president made publicly just days before. The release, coordinated through the Office of the Director of National Intelligence and the Pentagon, includes assessments dating back to the 1940s as well as more recent military encounter reports.

President Trump had told reporters on Tuesday that the files would be 'pretty interesting,' signalling the release was imminent. Administration officials confirmed Friday morning that the documents were being published on a dedicated government portal, with officials from the All-domain Anomaly Resolution Office (AARO) available to brief select congressional committees.

Among the materials released are previously redacted versions of internal Air Force Project Blue Book follow-up analyses, as well as more recent classified annexes to the 2021 and 2023 congressional UAP reports. Several documents reference encounters by Navy pilots in the Pacific and Atlantic that were not included in prior public disclosures, according to officials familiar with the release.

Experts and advocacy groups including the nonprofit UAPx and several former intelligence officials said the release represents the most substantive disclosure since the 2017 New York Times investigation that reignited public interest in the subject. However, some researchers cautioned that key documents from the CIA and NSA remained withheld on national security grounds, suggesting the full picture remains incomplete.

The release is expected to prompt immediate reaction from allied governments, particularly the United Kingdom and Australia, whose military personnel appear in some of the newly declassified encounter reports. Congressional oversight committees have already signalled they will hold hearings within weeks to question AARO and Pentagon officials about the contents.
