PURSUE Release 05: August 2026 UFO and UAP Files
Release Summary
PURSUE Release 05 declassifies historical Department of Energy facility security incident reports, nuclear complex intrusion logs, and retrospective AARO investigative case studies.
Release 05 connects atomic installation surveillance records with modern sensor standards, documenting recurring aerial incursions over sensitive national defense sites including Pantex, Sandia Base, and Los Alamos.

August 21 portal update
The Department of War published Release 05, opening declassified nuclear weapons complex surveillance logs and security incident files.
Department of Energy coordination
Multi-decade physical security records from DOE installations were processed through joint declassification review with AARO and military intelligence.
Scientific and plasma investigation link
Historical correspondence from Los Alamos physicist James Tuck and Pajarito astronomers was integrated into the official dossier.
What this tranche contains
- Declassified security incident reports and intrusion logs from Department of Energy nuclear weapons installations.
- DOE-UAP-D012 multi-site intrusion files and DOE-UAP-D001 Pantex plant unidentified object imagery.
- Historical Sandia Base green fireball investigations (DOW-UAP-D017) and early military scientific inquiry records.
- Correspondence from Los Alamos researchers investigating ball lightning and plasma phenomena as potential sighting causes.
How to read the release
- Verify the original security reporting thresholds used during historical recording intervals versus modern drone encounter standards.
- Separate perimeter security false alarms and drone incursions from instrumented multi-sensor encounters.
- Evaluate historical green fireball data in the context of astronomical observation programs like Project Twinkle.
Official positions to track
Department of War announcement
Affirms ongoing release of multi-agency historical files involving national security infrastructure and sensitive airspace protections.
Department of Energy statement
Confirms nuclear site security teams maintain strict reporting criteria for unauthorized airspace incursions, classifying unresolved events for federal evaluation.
What this release establishes
Release 05 provides documented accounts of recurring unidentified aerial encounters reported near nuclear research, weapons assembly, and storage complexes over multiple decades.
What it does not establish
The presence of unidentified sensor tracks over atomic installations does not establish foreign adversary or non-human origin without material confirmation.
Open research questions
How many historical Department of Energy incident logs underwent cross-correlation with modern military radar archives, and what sensor data was recovered from recent perimeter breaches?
