USS Roosevelt "Gimbal/GoFast"

Analytical Deep Dive

2014–2015

Executive Summary

The Roosevelt incidents involved U.S. Navy aviators operating from the East Coast after the introduction of upgraded radar systems.

Pilots reported repeated detections of unusual targets, including objects that appeared to remain airborne for long periods, travel against strong winds or move in formations. Two short infrared videos became publicly known as "Gimbal" and "GoFast."

The Gimbal video shows a distant infrared object that appears to rotate near the end of the clip. The GoFast video shows a small object tracked over the ocean that appears to move rapidly because of parallax.

AARO's later analysis concluded that GoFast did not demonstrate extraordinary speed. It estimated that the object was travelling roughly 39–46 miles per hour under the central reconstruction, with uncertainty caused by missing aircraft-position and atmospheric data.

The released Gimbal clip remains less definitively resolved. Competing interpretations include a conventional aircraft viewed through infrared glare, a distant object moving with the wind and a genuinely unusual vehicle accompanied by additional radar tracks.

1. Historical Context

During 2014–2015:

• Navy F/A-18 squadrons received upgraded APG-79 active electronically scanned array radars.
• Improved sensor sensitivity increased the detection of small or distant objects.
• East Coast training areas contained aircraft, drones, balloons, ships and classified exercises.
• Pilots reported stigma and uncertainty about how to document unusual contacts.
• Targeting-pod imagery was optimized for combat identification, not scientific measurement of unknown objects.
• The USS Theodore Roosevelt carrier group prepared for deployment to the Middle East.

The incidents later influenced changes in Navy UAP-reporting procedures.

2. Timeline

2014

Pilots began reporting unusual radar contacts off the U.S. East Coast.

Some accounts described:

• Targets appearing at high altitude.
• Objects remaining airborne for many hours.
• Tracks moving against prevailing winds.
• Repeated operations in training airspace.
• Near-collision concerns.

Near-Miss Report

Pilot Ryan Graves later described a case in which two aviators saw a dark cube enclosed in a transparent or translucent sphere pass between their aircraft.

This event was not captured in the publicly released Gimbal or GoFast videos.

January 2015: GoFast

An F/A-18 crew tracked a small infrared object over the ocean.

The video display created the impression of rapid movement across the water.

The crew reacted with surprise when the sensor achieved lock.

Gimbal Encounter

Another crew recorded a distant infrared object.

The clip includes pilots discussing:

• The target.
• A group of additional objects.
• Strong wind.
• Apparent rotation.

One pilot states that there is "a whole fleet" visible on another sensor display.

The publicly released video does not show that alleged fleet.

2017–2020 Public Release

The videos became public through media reporting and were later formally released by the Department of Defense.

The government confirmed that the footage had been recorded by Navy personnel but did not initially provide final identifications.

Later AARO Analysis

AARO analyzed GoFast using displayed range, altitude, sensor angle and aircraft information.

It concluded that parallax created much of the apparent speed and that the object did not exhibit anomalous performance. The office noted that the source file lacked complete georeferenced aircraft-position and atmospheric metadata, limiting precision.

3. Principal Witnesses

A. Ryan Graves

Former F/A-18 pilot.

Reported repeated unusual radar detections and near-miss concerns.

Graves did not personally record every publicly released clip but became a principal witness concerning the broader East Coast pattern.

B. Gimbal Aircrew

Recorded the infrared target and discussed additional objects.

Their real-time reactions show that they considered the event unusual.

Publicly available information does not reveal all sensor displays or classified supporting data.

C. GoFast Aircrew

Tracked the small object over the ocean.

The crew's excitement reflected the apparent difficulty of acquiring and maintaining sensor lock.

The video does not provide a clear visual shape.

D. Additional Roosevelt Aviators

Several pilots later reported objects with varied appearances, including:

• Cubes within spheres.
• Small spheres.
• Unidentified radar tracks.
• Objects apparently stationary in strong winds.

These reports should not automatically be treated as observations of one type of craft.

4. Physical Evidence

Evidence includes:

• The Gimbal infrared video.
• The GoFast infrared video.
• Pilot testimony.
• Radar and targeting-pod reports.
• Operational records.
• Later government analyses.
• Reporting-procedure changes.

No material was recovered.

No public raw radar data show the entire claimed fleet.

No range information is visible in the Gimbal clip sufficient to establish absolute speed and size with certainty.

GoFast includes enough display information for approximate geometric analysis, though key aircraft-location and atmospheric data are absent.

5. Official Investigation

The Navy confirmed that the videos were authentic military recordings.

The incidents were reviewed through UAP-related defence programs and later by AARO.

AARO concluded that GoFast's apparent extreme speed resulted substantially from motion parallax. Its published methodology estimated speeds far below the impression created by the background ocean movement.

The public status of Gimbal has remained more cautious. The video shows a real infrared target, but the released footage alone does not establish extraordinary flight.

6. Skeptical Explanations

GoFast as a Balloon or Slow Object

Strengths:

• AARO's geometric analysis produced moderate speed estimates.
• The object's apparent motion is strongly affected by the fast-moving aircraft and sensor line of sight.
• Small balloons can drift at altitude.
• No propulsion, acceleration or manoeuvre is visible.
• The object may have been moving near wind speed.

Weaknesses:

• Exact wind and aircraft-position data were unavailable.
• The object's precise altitude remains model-dependent.
• The crew believed it was unusual.
• AARO did not publicly identify one specific balloon.

GoFast as a Bird

Strengths:

• The calculated speed is compatible with some birds.
• A bird can appear as a small infrared target.
• Marine birds operate over the ocean.

Weaknesses:

• The estimated altitude in some reconstructions may be high for a bird.
• No wing motion is visible, though resolution is poor.
• The sensor's infrared appearance is indistinct.

Gimbal as a Distant Jet Aircraft

Strengths:

• A jet viewed nearly from behind may appear as a compact infrared source.
• Engine exhaust creates glare larger than the aircraft.
• The dark or bright apparent shape may be an optical artifact.
• Apparent rotation may result from the targeting pod's internal derotation mechanism and glare.
• A distant aircraft could be moving with the wind while appearing nearly stationary.

Weaknesses:

• No conventional aircraft was publicly identified.
• The crew believed the target lacked ordinary flight characteristics.
• Pilots reported a formation of other objects.
• The degree to which sensor mechanics alone explain the apparent rotation remains debated.

Infrared Glare and Sensor Rotation

Strengths:

• Infrared glare can obscure an aircraft's true outline.
• Optical elements in the pod rotate to stabilize imagery.
• Background features may remain stable while the glare pattern changes.
• Similar effects can be reproduced with bright thermal sources.

Weaknesses:

• The object's rotation appears visually striking.
• Supporters argue that image details rotate in a manner inconsistent with glare alone.
• Complete classified sensor metadata are unavailable.

Radar Reflectors or Balloons

Strengths:

• Radar-enhancing balloons can generate strong returns.
• Cubic reflectors may be suspended inside spherical balloons.
• Such devices are used for testing, surveillance and electronic warfare.
• Long endurance and wind-driven movement are natural.
• Radar upgrades would make them easier to detect.

Weaknesses:

• The Navy did not publicly identify a reflector program.
• Some pilots reported movement inconsistent with simple drifting.
• Near-miss objects were perceived as solid and structured.

Classified Testing

Strengths:

• Navy training ranges are used for advanced systems.
• Electronic warfare can create false radar tracks.
• Balloons, drones and decoys may be undisclosed.
• Improved radar could detect previously invisible test equipment.

Weaknesses:

• Allowing unbriefed pilots to approach unknown devices creates safety risks.
• The sightings reportedly continued over long periods.
• Some objects entered active training lanes.

7. Arguments from UAP Researchers

Supporters emphasize:

• Repeated pilot reports.
• Upgraded radar.
• Multiple sensor modes.
• Near-collision claims.
• Objects apparently stationary in high winds.
• The Gimbal rotation.
• The report of a fleet.
• Lack of visible conventional propulsion.
• Duration over weeks or months.

Some analyses reconstruct Gimbal as an object reversing direction at relatively close range.

Other models place it much farther away and interpret it as an aircraft. The available video does not fix the distance decisively.

8. Modern Historical Assessment

The Roosevelt cases should not be treated as one homogeneous event.

GoFast has been substantially demystified: the public footage does not show an object moving at extraordinary speed.

Gimbal remains more ambiguous because:

• Range is uncertain.
• The visible shape is dominated by infrared processing.
• The claimed additional radar formation is not publicly available.
• The apparent rotation may involve sensor optics.

The broader pilot reports deserve aviation-safety attention even if many objects were balloons, drones, reflectors or ordinary aircraft.

9. Critical Analysis Guide

A. Separate the Videos from the Broader Wave

Do Gimbal and GoFast show the same type of object?

Were the cube-in-sphere reports recorded on either video?

B. Calculate Parallax

How much apparent background motion results from the F/A-18's own speed and turn?

What speeds remain after geometry is reconstructed?

C. Determine Gimbal Range

Was the object 10 nautical miles away, 30 miles away or farther?

How does each assumption affect size and motion?

D. Examine Pod Optics

Does the targeting pod rotate internal mirrors at the same moment as the apparent object rotation?

E. Seek Supporting Radar

Is the reported fleet visible in preserved radar data?

Were tracks correlated with known aircraft, balloons or naval exercises?

10. Primary and Secondary Sources

Primary

• Gimbal and GoFast videos.
• Pilot reports.
• Navy operational records.
• Radar data where retained.
• Department of Defense video-release statements.
• AARO's GoFast case-resolution methodology.

Secondary

• AARO technical analysis.
• Interviews with Ryan Graves and other aviators.
• Optical and sensor-system analyses.
• Flight-path reconstructions.
• Studies of radar reflectors, balloons and motion parallax.

Overall Assessment

The Roosevelt encounters raised legitimate reporting and flight-safety concerns.

The released videos, however, do not demonstrate the extraordinary manoeuvres frequently attributed to them. GoFast appears to involve a moderately moving object whose speed was exaggerated by parallax.

Gimbal is still unidentified from the public data but may plausibly depict a distant aircraft whose infrared glare and sensor behaviour created the appearance of a rotating craft.
