The Gimbal UAP Video Explained — Pentagon's Most Studied Declassified Footage
The Gimbal video is the most technically discussed of the three officially declassified Pentagon UAP videos — more contested than the Nimitz FLIR1 and more analytically rich than GoFast. Recorded by an F/A-18 Super Hornet pilot off the U.S. East Coast in January 2015, it shows an object rotating without visible propulsion, defying known aerodynamic constraints. Its release in December 2017 by the New York Times — alongside FLIR1 — opened the modern disclosure era. AARO has designated the Gimbal case officially unresolved after full investigation.
What the Gimbal Video Shows
The Gimbal video was captured by an Advanced Targeting Forward-Looking Infrared (ATFLIR) pod aboard an F/A-18 Super Hornet flying off the U.S. Atlantic coast in January 2015, during the USS Theodore Roosevelt carrier strike group's sustained encounter period. The video shows a dark, roughly elliptical object moving against a cold sky background. Near the end of the footage, the object rotates — or appears to rotate — to a different orientation without any accompanying change in flight path, speed, or observable propulsion signature.
The word 'Gimbal' was the designation given by the naval aviators in the cockpit, heard in the audio: 'Look at that thing. It's rotating.' The name became the video's official identifier. Running approximately 34 seconds in the publicly released version, it was recorded using the same ATFLIR system used to capture the Nimitz FLIR1 footage eleven years earlier.
Declassification and Release History
The Gimbal video was classified after the January 2015 incident and held within the USS Theodore Roosevelt carrier strike group's intelligence reporting chain. Christopher Mellon — former Deputy Assistant Secretary of Defense for Intelligence — obtained copies of the Gimbal and GoFast videos from a source within the military and provided them to New York Times journalists in 2017. They were published alongside the FLIR1 video on December 16, 2017 in the story that revealed the existence of AATIP.
The Pentagon officially confirmed the videos' authenticity in April 2020, when all three — FLIR1, Gimbal, and GoFast — were formally released by the Department of Defense with a statement that they 'had been released to the public to clear up any misconceptions by the public on whether or not the footage that had been circulating was real.' The official release acknowledged only that the objects were unidentified — it did not address the rotation phenomenon or provide any alternative explanation.
The Rotation Debate
The object's apparent rotation is the most analyzed and disputed element of the Gimbal video. Two competing explanations have been proposed, neither fully accepted.
The prosaic hypothesis: the rotation is an artifact of the ATFLIR gimbal mechanism itself — as the pod tracks the object across a temperature gradient boundary, the sensor's internal derotation system could produce the appearance of rotation in the video output, while the object itself is stationary in its orientation. ATFLIR pods use a gimbal system to stabilize the field of view, and some analysts argue the visual rotation is a sensor artifact rather than object behavior.
The anomalous hypothesis: the pod's derotation system compensates for aircraft roll and yaw, not for the tracked object's orientation. If the rotation is tracking an actual change in the object's orientation, it represents controlled rotation of a craft with no visible control surfaces or rotational mechanism — a physical anomaly.
Luis Elizondo, who reviewed the classified full version of the recording as AATIP director, has stated that the sensor artifact explanation does not account for all elements visible in the classified version of the footage. AARO's investigation concluded the case remains unresolved and did not publicly endorse either interpretation.
AARO Investigation and Status
AARO reviewed the Gimbal case as part of its mandate under the 2022 NDAA. The case falls within the USS Theodore Roosevelt encounter cluster (2014–2015), which AARO investigated comprehensively given the quality and quantity of sensor data. AARO's finding: officially unresolved. No prosaic explanation — known aircraft, balloon, atmospheric phenomenon, sensor artifact — was found that accounts for the full observed data record including the multi-platform corroboration from both the Gimbal and accompanying GoFast recordings made in the same operating area.
The Gimbal case is significant in AARO's database for being one of the few cases where a specific physical behavior (the rotation) generated formal analytic disagreement among professional defense analysts with access to classified sensor data — not just public commentators. That internal disagreement, reflected in multiple congressional briefings, is why AARO declined to resolve it in favor of the sensor-artifact hypothesis despite its surface appeal.
