The Department of War (DOW) on Friday released its seventh batch of 28 Unidentified Anomalous Phenomena (UAP) files, bringing the total number of archived documents to 478 under the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE) initiative [6][12][14]. This release describes multiple 2026 sightings of mysterious matte black, triangular objects observed near sensitive U.S. sites in the Western United States [6][9][10].

These newly disclosed records detail aerial technology that officials state "exceeds what the United States is capable of creating in the near future" [9]. The nature of these reported objects and their presence near critical national security locations holds significant implications for defense and national security.

## What the Records Show

Documents in this release describe triangular UAPs with seamless, featureless surfaces and estimated wingspans of 9 to 15 feet [6][7][9][10]. These objects were observed performing extraordinary movements, including controlled vertical ascents, silent hovering for about 20 seconds at 200-300 feet, and high-speed horizontal flight up to 1,800 mph [7][9][10]. Maneuvers were described as lasting approximately two to three seconds, all without sound, vapor trails, or aviation lights [9][10][16].

Thermal signature reports varied, with some indicating a "consistent heat signal" or "steady heat signature," while others detected "no heat source," or stated that their "heat signature could not be detected by thermal equipment" [6][12][13][16]. Federal agents and military observers noted the objects vanished suddenly and silently [8][10].

Other documents in this release included reports on alleged paranormal activity at Utah's Skinwalker Ranch, a 2008 Bigelow Aerospace Advanced Space Studies (BAASS) Project Management Plan that revealed efforts to lobby for "biological material of potentially non-human origin," a redacted 2002 Roswell affidavit, and a May 1963 White House-level report discussing public disclosure of recovered space-vehicle fragments [11][16]. Historical UFO sightings from the 1940s and 1950s were also included [6][13]. The release contained no videos, with accompanying images being illustrations [10][16].

## The Transparency Initiative

Chief Pentagon Spokesman Sean Parnell confirmed the release, stating, "Today, the Department of War is publishing the seventh release of declassified and historical Unidentified Anomalous Phenomena (UAP) files as part of the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE)" [12][14]. Parnell added that the Department of War plans to release additional files on a rolling basis, with the department actively working on the next release [14]. President Donald Trump established the PURSUE initiative in February 2026 to increase transparency regarding UAP and alien life information [4][9]. Parnell was named chief Pentagon spokesperson and assistant to the secretary of defense for public affairs in February 2025 [1][2][3].

## What We Could Not Confirm

PrimaryBrief could not confirm the precise locations of the sensitive U.S. sites mentioned in the reports. The files do not definitively state the origin or nature of the described triangular objects. We also could not confirm the reasons for the inconsistent thermal signature reports across different observations of these UAPs.
