Transmedium Object — Pacific Naval Zone
UAP entered the ocean without deceleration, tracked by sonar at 900m depth for 11 minutes, re-emerged and departed at hypersonic speed. First officially documented transmedium UAP event.
On February 12, 2023, a U.S. Air Force F-16 Fighting Falcon shot down an unidentified object over Lake Huron, Michigan — the fourth aerial intercept and shootdown of an unidentified object in North American airspace in four days following the balloon episode over South Carolina. The Lake Huron object was tracked by NORAD, engaged by a Sidewinder missile, and fell into the lake. The DoD classified the cockpit video of the intercept. That video was subsequently released in PURSUE Release 02 (May 22, 2026), marking the first publicly available footage of a live UAP intercept and shootdown by a U.S. military aircraft.
The Lake Huron shootdown occurred within a remarkable four-day window of aerial intercepts over North America. On February 4, 2023, a large Chinese surveillance balloon was shot down off the coast of South Carolina after transiting the continental United States. Three subsequent intercepts followed: a cylindrical object shot down over Deadhorse, Alaska on February 10 (described by officials as 'octagonal' with strings attached and no identifiable payload); an object shot down over the Yukon in Canada on February 11, with Canadian CF-18s firing the AIM-9 Sidewinder; and the Lake Huron object on February 12, also shot down by a U.S. F-16 with an AIM-9.
The three objects following the Chinese balloon were notably different in character. They were smaller, operated at lower altitudes (approximately 20,000 feet for Lake Huron), and produced no surveillance payload identification. President Biden subsequently attributed the three non-balloon objects to 'benign' sources — likely private or commercial entities — but acknowledged that the objects' nature had not been definitively determined. AARO was involved in the post-shootdown analysis. The recovered debris from the Lake Huron object was limited due to the water recovery challenge, and no complete reconstruction of the object was publicly confirmed.
The classified cockpit video from the Lake Huron F-16 intercept was released in PURSUE Release 02 (May 22, 2026) as part of the DoD's NDAA Section 1841 declassification obligations. The video represents the first publicly available footage of a U.S. Air Force aircraft shooting down an airborne UAP — a category of footage that the DoD previously treated as categorically classified and not subject to release.
The PURSUE R02 version of the video is AI-analyzed in the Now Declassified archive with tier classification, behavior tagging, and key quote extraction. The file is available at /pursue/release-02 with full context on what the cockpit video shows during the engagement sequence, the missile impact, and the post-intercept observation of debris. The video's release alongside the Sandia nuclear facility report and other R02 materials makes Release 02 arguably the highest-value PURSUE release to date in terms of raw evidential content.
The Lake Huron shootdown has several distinct implications for the archive record beyond the footage itself. First, it established a precedent for government action against unidentified aerial objects in defended U.S. airspace. The shoot-to-down order for objects that could not be identified as non-threatening represents a significant shift in how the U.S. government operationally handles UAP — from passive observation and tracking to active kinetic response. Prior to February 2023, the official position was that UAP did not represent an immediate safety threat and were tracked but not engaged.
Second, the Lake Huron incident forced a degree of public transparency about NORAD's UAP tracking capabilities that had not previously been acknowledged. Officials confirmed that NORAD had been updating its radar filtering parameters to detect smaller objects after the balloon episode — and that this recalibration was revealing many more aerial objects than were previously being tracked. The implication is that the pre-2023 absence of UAP radar returns in NORAD data was partly a function of filter settings rather than object absence, a finding that has significant retrospective implications for the historical UAP archive.
As of the 2026 NARA archive release, the official classification of the Lake Huron object (and the two concurrent Alaskan/Canadian objects) remains unresolved. President Biden's public attribution to 'benign' sources was not accompanied by specific identification of what the objects were, who launched them, or what their payload (if any) was. AARO's case-resolution database does not include publicly accessible individual case determinations for the three February 2023 objects.
The debris recovery from Lake Huron — conducted by the U.S. Navy and Coast Guard — was challenging due to water depth and winter conditions. Official statements indicated that some debris was recovered but a complete reconstruction was not achievable. The classified nature of the full recovery analysis means that the public record for the Lake Huron object is, as of 2026, still the PURSUE cockpit video and the AARO brief summary rather than a comprehensive case investigation comparable to the Nimitz or Gimbal cases. The incident is notable for being one of the few cases in the modern archive where government action (rather than observation) is the primary documented event.

UAP entered the ocean without deceleration, tracked by sonar at 900m depth for 11 minutes, re-emerged and departed at hypersonic speed. First officially documented transmedium UAP event.
USS Nimitz Carrier Strike Group radar operators tracked an unknown object for two weeks before F/A-18 pilots were tasked to intercept. Commander Fravor observed a white 40-foot oblong object with no wings, propulsion, or exhaust hovering over a roiling sea disturbance before it accelerated away instantaneously. FLIR footage declassified by DoD in 2020.
An F/A-18 Super Hornet ATFLIR pod captured a disc-shaped object visibly rotating against the direction of wind at 25,000 feet. The object moved into the prevailing wind and appeared to rotate continuously with no visible means of propulsion. DoD officially released the FLIR footage in 2020; AARO lists it as unresolved.
