THE DOCUMENT
(Unchanged: CIA-UAP-D001, “Intelligence Information Report, USSR, 1973”, a document from the U.S. Department of War’s PURSUE Release 02, published at war.gov/ufo on 22 May 2026. It is a CIA intelligence information report, the agency’s first document to appear in either PURSUE release.)
Why this one is worth your time
The arrival of the first Central Intelligence Agency file in PURSUE will draw attention on the letterhead alone. CIA-UAP-D001 is worth a briefing partly for that reason and partly for the opposite one: it is a low-stakes example of a document type that is easy to overrate, the raw intelligence report. This briefing sets out the small UAP observation buried inside the file and explains what an intelligence information report is and is not, so that the next time a “CIA UFO document” surfaces, the letterhead does not do more work than it should.
What the document says
CIA-UAP-D001 is an intelligence information report, an IIR. The bulk of this particular report concerns human intelligence gathering inside the Soviet Union and has nothing to do with UAP. The UAP content is a single passage, section 14.
What an IIR is, in the document’s own terms. An IIR is raw intelligence: information collected from a human source, written down, and circulated, so that analysts elsewhere can weigh it against everything else they know. It is the intelligence equivalent of a witness statement at the raw-reporting stage. This is why CIA-UAP-D001 carries language characterising its own content as informational and not finally evaluated. That is the document telling you, in its own words, what stage of the process it belongs to: an IIR records that a source said something and that the agency thought it worth filing.
Where the UAP material sits. It is genuinely a single section of a longer, unrelated report. UAP information inside intelligence archives rarely arrives as a dedicated study; here it arrives as section 14 of a document about something else, picked up because a source happened to mention it.
The observation in section 14. In the summer of 1973, somewhere in the USSR, the source described an airborne, luminous, bright green object of unknown nature. Over several minutes, concentric circles formed around it. Then it dissipated. There was no sound. The source offered no opinion on what it was and could give no further detail.
What the document does not say
It does not say what the object was. The account is single-source, uncorroborated, undetailed, and explicitly unevaluated by the agency that filed it. The document supplies no time, no precise location and no direction.
It does not, in its own characterisation, claim to be a finished assessment. The CIA filed it as raw reporting; the file records that a source described something, not that the agency confirmed it.
It is the first CIA document in either PURSUE release, and the only one to date. No second CIA file accompanies it in these releases.
From the record
“Intelligence Information Report, USSR, 1973.” The document’s own title
A luminous, bright green object of unknown nature, with concentric circles forming around it over several minutes before it dissipated, silently. Section 14, the source’s account
The content is informational and not finally evaluated. The report’s own characterisation of its tier
Where the case connects
The colour recurs: as Release 02 Briefing 3 set out with the New Mexico green fireballs, green is a recurring colour across these reports. The way the UAP content appears here, one section of an otherwise unrelated report, is also typical of how such material sits inside intelligence archives, where it is picked up incidentally rather than studied directly. Release 02 Briefing 1 covers the Release 02 chain-of-custody caveat, and Briefing 1 of Release 01 covers PURSUE and the tier system.
The file also leaves its own loose ends. It is single-source and the source could add no detail; it carries no time, location or direction that would let anyone test the account; and the agency itself left it unevaluated. Any later tranche that releases corroborating reporting, or a CIA assessment of this observation, lands in this series when it does.
