The Department of War (DoW) has made public a collection of documents labeled PR71 that detail a 2022 encounter in which a United States Air National Guard F‑16C fighter jet engaged and destroyed an unidentified aerial phenomenon (UAP) above Lake Huron. The release, part of the Pentagon’s PURSUE (Public Release of Unidentified Aerial Phenomena) policy, contains sensor readouts, cockpit audio, and video footage captured during a routine training sortie. According to the file metadata, the aircraft was operating under a redacted callsign and was equipped with an AN/APG‑68 radar system and an AN/ASQ‑213 targeting pod.
While cruising at roughly 15,000 feet, the crew detected an object moving at speeds exceeding Mach 1.2. The UAP displayed no visible propulsion system, wings, or exhaust plume, appearing instead as a bright, oblong shape on the pod’s infrared video feed.
Initial attempts to establish communication using standard hailing frequencies received no response. The object’s flight path was described by the pilot as “erratic” and “not consistent with known aircraft behavior.” After the platform failed to comply with identification protocols, the pilot requested and obtained clearance to engage the target with an AIM‑120 AMRAAM missile. Audio transcripts from the cockpit capture the pilot’s observation that the “contact is maneuvering in ways that don’t make sense,” followed by the clearance to fire. The missile struck the UAP, after which the debris fell into Lake Huron.
No physical remnants have been recovered, and the report does not identify the object’s origin, leaving it classified as either foreign or unknown. The All‑Domain Anomaly Resolution Office (AARO), operating under the Office of the Secretary of Defense, reviewed the material before its release.
AARO officials noted that the engagement had remained classified due to the sensitivity of the aircraft’s capabilities and the nature of the encounter. While the exact date of the incident is omitted, timestamps in the files indicate it occurred in the latter part of 2022. The declassification aligns with a broader DoW effort to increase transparency around UAP incidents involving military assets.
The agency has signaled that it may seek additional information from the Air National Guard unit, including maintenance records and pilot debriefings, and it plans to interview the pilot and other witnesses to gain further insight. Analysts emphasize that, without recovered material, definitive conclusions about the phenomenon’s characteristics remain out of reach.
Nevertheless, the sensor data—radar returns, infrared video, and cockpit commentary—provide a rare glimpse into a high‑speed, high‑altitude encounter that prompted an armed response. The release of PR71 adds to a growing docket of UAP documentation made available under the PURSUE framework, reflecting an ongoing shift toward openness while still protecting operational security. Future examinations of the data may help refine understanding of the object’s flight dynamics, but the lack of tangible evidence means many questions will likely persist.
