Key Intelligence Findings
AIS Blackout Confirmed — 6 Events
Deliberate AIS transponder deactivation detected. Each event represents a period where LAPEROUSE was operating outside electronic surveillance. Consistent with covert cargo transfer or evasion operations.
Velocity Fraud — 2 Speed Anomaly Events
AIS SOG field manipulated to broadcast physically impossible speeds up to 59.0 knots. Systematic falsification of movement data to corrupt automated tracking algorithms.
Evasion Navigation — 25 Zigzag Events
Erratic course-over-ground patterns up to 152.9° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers or anchor position AIS noise.
