Key Intelligence Findings

AIS Blackout Confirmed — 16 Events

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

GPS Spoofing — 1 Position Jumps

AIS coordinates fabricated at impossible locations. Maximum jump of 3,111 km confirms the AIS transmitter is broadcasting false positions. Systematic identity concealment is in progress.

Evasion Navigation — 26 Zigzag Events

Erratic course-over-ground patterns up to 98.9° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers or anchor position AIS noise.
