Unidentified objects reported near sensitive U.S. military installations are drawing fresh international attention after the release of declassified government files. The most recent batch of Pentagon UAP files, released on August 7, 2026, contained 41 documents, images and videos in the PURSUE database. According to the reports on which this article is based, black triangular objects were seen at least three times over the past year within the perimeters of sensitive national security sites. Those figures could not be independently confirmed.
Reported speed and size
Eyewitness accounts cited in the reports describe one black triangular object covering about 1.5 miles (2.4 km) in roughly three seconds. That works out to about 1,800 mph (2,900 km/h), comparable to the top speed of advanced fighter jets. The object’s wingspan was reportedly estimated at 9 to 15 feet and its thickness at 1 to 2 feet, and officials are said to have released preliminary sketches. These details are unverified, and visual speed estimates are known to be unreliable.
No engine signature
The reports say the objects made no sound and showed no exhaust. Thermal scans reportedly found no engine heat, and the craft had no visible wings, air intakes or cockpit. Fighter jets flying at supersonic speeds normally produce loud noise and visible exhaust. These specific observations also remain unconfirmed.

Triangular Unidentified Anomalous Phenomena (UAPs), often historically referred to as “Black Triangles,” are a highly prominent class of UAP characterized by large, dark, silent, and geometric hulls with illuminated corners. Reports of these craft have spanned decades, consistently describing flight dynamics that seemingly defy conventional aviation physics, such as instantaneous acceleration or motionless hovering without visible propulsion systems or rotor wash.— UFO mania (@maniaUFO) October 22, 2026
Origin remains unknown
U.S. officials are reported to believe the objects are not American technology. Whether they belong to a rival power such as China or Russia, or have some other origin, remains unanswered, and no evidence supports any attribution. A Pentagon spokesman has said more files will follow on a rolling basis.
