PURSUE Record — GIMBAL — U.S. Navy infrared UAP encounter, 2015: U.S. Navy · Atlantic Ocean — USS Theodore Roosevelt Carrier Strike Group · January 21, 2015

GIMBAL is a 34-second forward-looking infrared video filed under the U.S. Navy's sensor records and officially declassified by the Department of Defense on April 27, 2020. It captures an unidentified aerial object encountered on January 21, 2015 by aircrew from the USS Theodore Roosevelt Carrier Strike Group over the Atlantic Ocean. Now catalogued as part of PURSUE Release 01 — the May 8, 2026 Department of War declassification effort — GIMBAL remains one of the most technically contested UAP records in the public domain.

What this record contains

The record consists of a single video file (1 part) released by the U.S. Navy. It was filmed from an F/A-18F Super Hornet operating at approximately 25,000 feet, using the aircraft's forward-looking infrared (FLIR) targeting pod. The footage shows a saucer- or capsule-shaped object that appears to rotate against the prevailing wind while the infrared camera tracks it. Accompanying audio captures the aircrew's real-time reactions — most notably the phrase "There's a whole fleet of them, look on the SA" — indicating that radar and sensor displays were showing more than a single contact at the time of the encounter. The "gimbal" designation itself derives from the central interpretive question the footage raises: whether the apparent rotation of the object is a genuine physical motion or an artifact produced by the infrared targeting system's mechanical gimbal lock mechanism.

The public release does not include detailed supporting documentation beyond the video itself — no incident report, no formal case summary — making the footage the primary evidentiary artifact for this record.

Sensor & operational context

FLIR targeting pods aboard F/A-18s are designed for tracking fast-moving airborne and surface targets; they are not scientific instruments, and their data products carry known limitations. The gimbal lock phenomenon in infrared tracking systems occurs when the pod reaches the mechanical boundary of its rotational range, causing the image to spin as the system resets orientation. Skeptics of the GIMBAL footage argue persuasively that the object's apparent counterclockwise rotation is consistent precisely with this artifact, not with any motion of the object itself. This is a legitimate sensor-physics argument grounded in how these systems work. At the same time, the pilot audio referencing multiple objects tracked on the situational awareness display suggests independent corroboration beyond the single FLIR frame — a factor that complicates a pure sensor-artifact dismissal. The USS Theodore Roosevelt CSG was conducting training operations in the Atlantic at the time, providing a well-documented operational backdrop against which the encounter occurred.

What this does and does not prove

What the record documents factually: a U.S. Navy FLIR system captured an object of indeterminate origin on January 21, 2015, and the footage was deemed significant enough to be preserved, formally reviewed, and ultimately declassified. What it does not establish: the nature, origin, or capabilities of the object. The gimbal-lock debate is unresolved in the public record — credible analysts hold both positions, and neither has been definitively validated by the Navy's formal assessment. The pilot audio adds weight to the encounter but does not resolve what was tracked. "Unresolved" in this context means the case has not been explained to the satisfaction of investigators, not that any anomalous or non-human explanation has been confirmed.

How it fits PURSUE Release 01

Within the 162-document PURSUE Release 01 package — which spans 28 videos, 14 images, and 120 PDFs sourced from military sensor archives, NASA records, and FBI files dating to 1947 — GIMBAL represents the contemporary military sensor video category alongside GOFAST and FLIR1 (also from the Roosevelt CSG era). It is one of the release's highest-profile entries precisely because it was already publicly known before May 8, 2026; its inclusion in the formal release gives it official provenance within the PURSUE catalogue and places it alongside dozens of lesser-known cases now entering the public record for the first time.
