Pentagon's New UFO Files Describe Silent Black Triangles Over Secure Sites

Seventh Release Adds 28 Files to Growing Archive

The U.S. Department of War published its seventh tranche of declassified unidentified anomalous phenomena files on Friday, October 23, 2026. According to CBS News and Scientific American, the 28 new PDFs belong to the presidential unsealing and reporting system for UAP encounters, an effort that began releasing records in May and has now grown to 478 files.

Federal Agents Describe a Matte Black Triangle

The centerpiece is a memorandum from two federal special agents with extensive operational experience alongside government agencies. The Guardian reports that the two men were at a sensitive site in the western United States earlier this year when they saw a matte black, triangular object about three miles away, most resembling a delta-wing drone with a continuous, featureless, nonreflective surface.

A Perfectly Vertical Climb in Absolute Silence

The All-domain Anomaly Resolution Office report, quoted by CBS News, says the craft executed a slow, controlled, perfectly vertical ascent of roughly 200 to 300 feet directly over a ridgeline, holding a completely static orientation without tilting, swaying, or wobbling. The ascent occurred, investigators wrote, in absolute acoustic silence. It then hovered, shifted into horizontal flight, and descended toward a canyon drainage. A later ground search found no debris or sign of impact.

Three Seconds, 1.5 Miles, an Estimated 1,800 Mph

The witnesses calculated that the object covered about 1.5 miles in some three seconds, roughly 1,800 miles per hour, before vanishing suddenly and silently within seconds, leaving no exhaust trail. Interesting Engineering reports its estimated wingspan at 9 to 15 feet, depth at 6 to 9 feet, and thickness at 1 to 2 feet, with no normal aviation lights and no sound. One memo variant put its length near 2.7 meters with a 3.9-meter wingspan, crossing 2.5 kilometers in under three seconds to an altitude of 61 to 91 meters.

The Third Triangle Case in Recent Weeks

The release identifies this as the third triangular object observed over a sensitive test site in recent weeks. The tranche also revisits older cases, including an equilateral triangle with a red light at each corner near Colorado Springs in October 2023 that reportedly accelerated to Mach 1 or 2, plus a metallic elliptical object over Sweden in 1953, a 1957 sighting in Saudi Arabia, and flying saucer reports over Catalina Island in California.

Official Line Unchanged, but Pressure for Data Grows

The official position remains that a historical review has confirmed no UAP case as extraterrestrial technology, and that most resolved cases trace to balloons, drones, aircraft, or birds. Still, a silent craft performing such maneuvers above a secure facility raises airspace security questions. Attention now turns to when the next tranche appears, and whether redacted dates, locations, and any radar or video evidence will follow.
