Key Intelligence Findings

AIS Blackout Confirmed — 2 Events

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

Evasion Navigation — 18 Zigzag Events

Erratic course-over-ground patterns up to 104.4° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers.

◐ Dark Vessel Events

Indicator: AIS-MAN-001 · 2 AIS blackout events detected

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.
