Key Intelligence Findings
AIS Blackout Confirmed — 2 Events
Deliberate AIS transponder deactivation detected. Each event represents a period where C-LIBERTY 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 125.3° 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.
