DOE/NNSA drone-incursion Operations Reports (2018–2021).

Operations Reports filed by the DOE/NNSA Protective Force Division documenting suspected unauthorized drone incidents near Lawrence Livermore National Laboratory and other DOE facilities, May 2018–April 2021, plus correspondence containing historical UAP references. Obtained via FOIA by researcher Douglas D. Johnson; follow-on FOIA work surfaced 57 drone incursions across 24 nuclear sites (2015–2019), including a Sept 29, 2019 large-drone swarm over Palo Verde NGS. Standout reports: the April 30, 2019 LLNL Site 300 'round silver drone' and a March 19, 2018 Sandia sighting (low, silent, alternating white/red LEDs). At least one report described an object without visible lights or flight surfaces. Candidate explanations span foreign (Chinese) reconnaissance to genuinely unidentified objects.
