Key Intelligence Findings
AIS Blackout Confirmed — 4 Events
Deliberate AIS transponder deactivation detected. Each event represents a period where SEAWAYS GATUN was operating outside electronic surveillance. Consistent with covert cargo transfer or evasion operations.
Velocity Fraud — 4 Speed Anomaly Events
AIS SOG field manipulated to broadcast physically impossible speeds up to 102.2 knots. Systematic falsification of movement data to corrupt automated tracking algorithms.
Evasion Navigation — 29 Zigzag Events
Erratic course-over-ground patterns up to 149.2° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers or anchor position AIS noise.
