Overview
- The Pentagon published the fourth PURSUE tranche on Friday, July 10, 2026, adding 40 files that the Department of War says will be followed by further releases.
- The tranche contains 19 videos, 14 documents, four audio recordings and three images drawn from the Pentagon, NASA, CIA, FBI and the Department of Energy.
- Among the newly disclosed items is an 18‑second 2025 infrared video from U.S. Indo‑Pacific Command showing a multi‑pronged, star‑shaped area of contrast over the Yellow Sea.
- The release also includes a newly detailed DOE report on a September 2015 object that entered restricted airspace over the Pantex nuclear weapons plant and prompted a lockdown and security response.
- Officials and the posted files stress the materials remain largely unresolved, include redactions to protect identities and sensitive sites, and are being reviewed for conventional explanations and potential national security implications.
