“GoFast” is an infrared targeting-pod recording made by a U.S. Navy F/A-18 aircrew off Florida in January 2015. In the clip, operators work to lock the sensor onto a small target while the ocean appears to sweep rapidly below it. Their excited reaction and the video’s visual geometry helped create the impression of an object traveling extremely fast just above the water. The Defense Department formally released the clip with “Gimbal” and “FLIR” in April 2020 and retained its characterization as unidentified at that time.

The image creates a classic parallax problem. A moving aircraft observes a target against a much more distant background, so the line of sight can traverse the ocean rapidly even when the target itself is moving modestly. Range, viewing angle, aircraft motion, wind, and target altitude must be combined before screen motion becomes physical speed. Without that reconstruction, the memorable name “GoFast” is a description of appearance, not a measurement.

AARO later published a case-resolution analysis using telemetry visible in the video and wind data. It estimated the object at roughly 13,000 feet rather than near the surface and calculated a possible groundspeed of about 5 to 92 miles per hour, with the wind near 69 miles per hour at that altitude. The office assessed with high confidence that the target did not demonstrate anomalous performance and said a lightweight object could account for its motion. It also noted that missing precise aircraft-position data prevented an exact target position, an uncertainty that remains relevant to independent reconstructions.

GoFast is therefore unusually useful within sensor evidence and military video: it shows how a genuine, authenticated encounter can look extraordinary before geometry is solved. The official assessment addresses the speed suggested by the public clip; it does not retroactively tell viewers exactly what object was recorded or resolve every contextual account from that training period. Together with the Gimbal video, it helped transform UAP into a major public issue. Its later analysis also demonstrates why released telemetry and explicit methods matter more than either a dramatic nickname or an argument from authority.
