Overview
- The Department of Defense posted a fourth tranche of declassified UAP (unidentified anomalous phenomena) files on Friday, July 10, 2026, adding 40 items that include 19 videos, 14 documents, four audio recordings and three images.
- Among the new videos is an 18‑second infrared clip submitted by U.S. Indo‑Pacific Command in 2025 that shows a multi‑pointed, star‑shaped area of contrast tracked over the Yellow Sea by military sensors.
- A Department of Energy report in the release describes a September 1, 2015 intrusion over the Pantex nuclear weapons plant in Texas where officers pursued a silent, diamond‑shaped object during a facility lockdown but did not identify a propulsion system.
- Other notable files document a 2020 infrared recording of a dark, ‘jellyfish‑like’ object over the Atlantic, a 2019 Navy range‑fouler report of a fast rectangular object that outran aircraft tracking, and archival records including 1949 Los Alamos ‘green fireballs’ and 1996 Space Shuttle imagery.
- Pentagon and AARO officials say the materials are informational, partly redacted to protect sensitive details and eyewitnesses, remain officially unresolved because of gaps in sensor metadata and chains of custody, and that further releases and reviews are expected which could affect national‑security and safety assessments.
