Key Intelligence Findings

AIS Blackout Confirmed — 6 Events

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

Velocity Fraud — 1 Speed Anomaly Events

AIS SOG field manipulated to broadcast physically impossible speeds up to 42.9 knots. Systematic falsification of movement data to corrupt automated tracking algorithms.

Evasion Navigation — 82 Zigzag Events

Erratic course-over-ground patterns up to 128.1° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers or anchor position AIS noise.

◐ Dark Vessel Events

Indicator: AIS-MAN-001 · 6 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.

Type Mismatch Assessment

AIS Declared Type

vessel_type=37 (Pleasure Craft)

Behavior Consistency

INCONSISTENT — year-round multi-port operations with 194 anomalous events are not consistent with pleasure craft use
