The Pentagon has released the sixth tranche of records under its PURSUE UAP disclosure initiative, ending a six-week wait since the previous release. Unknown Country is reviewing the new material and will report separately on significant findings.
(Unknown Country) — The Pentagon released a sixth tranche of declassified Unidentified Anomalous Phenomena records Friday, Sept. 18, 2026, just before 8 a.m. EDT adding another collection of government material to the growing public archive established earlier this year under the Presidential Unsealing and Reporting System for UAP Encounters, or PURSUE.
The release comes exactly six weeks — 42 days — after the fifth tranche was published Aug. 7, marking the longest interval between PURSUE releases so far.
The Pentagon began publishing records through PURSUE on May 8, following President Donald Trump’s February directive calling for federal agencies to identify and release government files concerning UAP, UFOs and purported extraterrestrial life. A second tranche followed May 22, with subsequent releases June 12, July 10 and Aug. 7. The intervals between those releases were 14, 21, 28 and 28 days, respectively. Release 06 breaks that pattern after a six-week pause.
PURSUE is being overseen by the Pentagon with support from the Office of the Director of National Intelligence as part of a government-wide effort to locate, review, declassify and publicly release UAP-related records held across federal agencies. The department has described the undertaking as involving dozens of agencies and potentially tens of millions of records spanning decades, including material that exists only on paper.
The government has also emphasized that the records included in the PURSUE archive concern unresolved cases. Their inclusion in the database does not mean the government has determined that an observation represents extraterrestrial technology or any other particular explanation. According to the Pentagon, cases can remain unresolved for several reasons, including insufficient data to make a definitive determination.
__________
The first five releases have brought together material from agencies including the Pentagon, FBI, NASA, Office of the Director of National Intelligence and other parts of the federal government. The archive has included historical documents as well as imagery, video, audio and records connected with more recent UAP reports. By the fifth release, the searchable PURSUE database contained hundreds of individual files.
The Pentagon has said the disclosure process is ongoing rather than a finite release of a predetermined collection. Its PURSUE directive states that new material will be released on a rolling basis as records are located and declassified, with additional tranches expected “every few weeks.”
Unknown Country is reviewing the newly released files in detail. As that analysis continues, we will provide additional reporting, context and commentary on significant records contained in Release 06 — including what is genuinely new, how the material relates to earlier releases and what questions may remain unanswered.
The complete PURSUE archive, including the newly released material, is available through the Pentagon’s Department of War website.
