Key Intelligence Findings

AIS Blackout Confirmed — 5 Events

Deliberate AIS transponder deactivation detected. Each event represents a period where OSLO BULK 12 was operating outside electronic surveillance. Consistent with covert cargo transfer or evasion operations.

Evasion Navigation — 13 Zigzag Events

Erratic course-over-ground patterns up to 82.7° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers.
