08 UNCLASSIFIED All-domain Anomaly Resolution Office CLEARED U.S. Department of Defense Open Publication For Case: “Go Fast” Feb 06, 2025 Case Resolution | February 6, 2025 Department of Defense OFFICE OF PREPUBLICATION AND SECURITY REVIEW Case Overview Case Essentials In January 2015, a U.S. Navy F/A-18F pilot Location: Eastern coast of Florida recorded an object using a Forward Looking Infrared (FLIR) sensor about 13,000 feet Date: January 2015 above the Atlantic Ocean off the coast of Object Altitude (reported): Near ocean’s Florida. surface The video appeared to show the object moving Object Altitude (assessed): 13,000 feet at high speed. AARO cannot definitively identify the object, but it displayed no Object Speed (reported): Appeared to anomalous performance characteristics. move at high speeds Object Speed (assessed): 5 mph - 92 mph The Department of Defense officially released the “Go Fast” video in 2020. It is available Object Shape (reported): Round for public viewing at the Navy’s FOIA Reading Room. Object Shape (assessed): Spherical or oblate ellipsoid Key Findings Reporter: U.S. Navy AARO assesses with high confidence that the Sensor: Forward Looking Infrared object did not move at anomalous speeds. AARO's analysis showed: Reported Behavior: Moved at high speeds near the ocean’s surface • The object’s altitude was Assessed Behavior: An object moving approximately 13,000 feet. between 5 and 92 mph at approximately • The object’s speed ranged from about 13,000 feet 32 m/s (72 mph) to 72 m/s (161 mph) depending on its heading relative to Summary of Findings: High confidence the wind. Compensating for the the object did not demonstrate anomalous wind’s contribution to the object’s performance characteristics speed, its approximate speed range is 2 m/s (5 mph) to 41.3 m/s (92 mph). • The object’s heading deviated as much as 32° from wind direction, though most simulations conducted during AARO’s analysis showed significantly less difference. The object did not move against the wind in any simulation.
