Key Intelligence Findings
AIS Blackout Confirmed — 2 Events
Deliberate AIS transponder deactivation detected. Each event represents a period where INDIGO RAY was operating outside electronic surveillance. Consistent with covert cargo transfer or evasion operations.
Evasion Navigation — 19 Zigzag Events
Erratic course-over-ground patterns up to 138.7° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers.
