UAP Document Archive: Official UFO Files from the US, UK & Brazil

We're reading every declassified government UFO file, page by page, so you don't have to.

US DoD PURSUE Releases · UK MOD & National Archives Files · Brazilian Air Force Records · NSA UMBRA Files

This is where WatchTheStars keeps its primary-source UAP research. We've pulled together the official government document releases — American, British and Brazilian — and we're reading through them systematically, publishing honest, plain-English write-ups of what each file actually says. No embellishment, no hype. Just what's on the page.

What the UAP Document Archive Project Is

Most UFO coverage works from press releases and secondhand summaries. We're trying to do something slower: read the actual documents. Since 2026, several governments have started declassifying and publishing genuine UAP records — thousands of pages between them, plus hours of video and radar footage. We've gathered the official releases we can get hold of and we're going through them properly, case by case, document by document, and writing up what's really there rather than what the headlines say is there.

This page is the index for that project. Below you'll find what each collection is, roughly how much material it contains, and links to the deep-dive pages and articles we've already published from it. It'll grow as we work through more of the archive — think of it as a living catalogue rather than a finished product.

The Collections

Scan the skies yourself

Kit we've tested and reviewed in full

Every file in this archive started with someone looking up and describing exactly what they saw. A decent pair of binoculars is still the best way to turn a strange light into an actual identification — aircraft, satellite, planet, or something worth writing down properly.

Best all-rounder

Opticron Adventurer 10×50

4.7Our full review

Sharp, bright and quick to aim — enough to pick out navigation lights, engine count and direction of travel on a distant aircraft.

For distant, faint targets

Celestron SkyMaster Pro 15×70

4.5Our full review

The extra aperture and magnification that turn "a light on the horizon" into something you can actually describe — which is where every good report starts.

Coverage So Far

These are the deep-dives and articles we've already published straight from the collections above. Each one is built from a specific document or case file, not secondhand reporting.

What the Pentagon's Files Mean for the UK

A British perspective on the US releases, and how they connect to the UK's own MOD files.

What's Coming

We're planning a recurring "document of the week" feature, working through the remaining unpublished files in each collection — starting with the unopened portions of the UK MOD volumes and the parts of the July 2026 US release we haven't covered yet. We'll also be building out dedicated sub-pages for each collection as coverage grows, rather than keeping everything on this one index.

If there's a specific document, case or release you want us to prioritise, the fastest way to reach us is through our about page.

Frequently Asked Questions

Yes. The documents referenced on this page are official releases from US government bodies including the Department of War (formerly the Department of Defense), the Department of Energy, the Department of State, the FBI and NASA, published under the PURSUE transparency initiative that began in 2026. Each file carries an official document reference number (for example DOE-UAP-D005 or DOW-UAP-D095) and was released through official government channels, not leaked or unverified sources.
The US releases are published at war.gov (formerly defense.gov) and referenced by AARO, the Pentagon's All-domain Anomaly Resolution Office. UK files are held by The National Archives at Kew, searchable in their catalogue under the DEFE and AIR series. Brazilian Air Force records are held by the Arquivo Nacional (Brazil's National Archive) in Rio de Janeiro. We link to the relevant official body in each section above rather than rehosting the files ourselves.
The US files are the most recent and the most numerous — four bulk releases of documents and videos through 2026 covering incidents from the 1940s to the present day. The UK files are older, drawn mainly from Ministry of Defence and National Archives records going back to the Cold War, released more gradually over the past two decades. The Brazilian files centre on two specific 1970s–90s cases — the Varginha incident and Operação Prato — and are notable because they include signed military conclusions, not just raw sighting reports.
We're working through them collection by collection rather than claiming to have covered everything at once — there are several hundred documents and dozens of hours of video across these archives, some of it still being processed. Where we've published a full write-up on a specific case or file, it's linked in the "Coverage so far" section above. We'll keep adding to this page as we work through more of the archive.
