Key Intelligence Findings

AIS Blackout Confirmed — 9 Events

Deliberate AIS transponder deactivation detected. Each event represents a period where KINDRED SPIRIT was operating outside electronic surveillance. Consistent with covert cargo transfer or evasion operations.

Velocity Fraud — 25 Speed Anomaly Events

AIS SOG field manipulated to broadcast physically impossible speeds up to 101.7 knots. Systematic falsification of movement data to corrupt automated tracking algorithms.

Evasion Navigation — 5 Zigzag Events

Erratic course-over-ground patterns up to 130.1° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers.

AIS BLACKOUT

⚠ HIGH SIGNIFICANCE: Dark vessel events represent deliberate AIS transponder deactivation — a primary indicator of intentional surveillance evasion, covert cargo transfer, or sanctions circumvention.
