Key Intelligence Findings
AIS Blackout Confirmed — 8 Events
Deliberate AIS transponder deactivation detected. Each event represents a period where H A SKLENAR was operating outside electronic surveillance. Consistent with covert cargo transfer or evasion operations.
Evasion Navigation — 25 Zigzag Events
Erratic course-over-ground patterns up to 129.8° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers or anchor position AIS noise.
