IRGC Fast-Boat Shadowing of U.S. and Commercial Shipping Near Kharg Within 24 Hours
Theater: Northern Persian Gulf

Moderate confidence (70%)
Risk direction: escalatory · Impact: HIGH
Full prediction
Within the next day, IRGC naval units are likely to begin aggressive shadowing and close-approach maneuvers against U.S. and selected commercial vessels operating near Kharg Island and inside the northern Gulf. Expect laser illumination, flyovers by drones and helicopters, and temporary course-interference without live fire, calibrated to signal red lines after the U.S. strike on the Iranian tanker. This will heighten collision and miscalculation risk but likely fall short of direct attacks on U.S. hulls as Tehran gauges Washington’s response threshold. Confirmation would come via AIS anomalies, shipowner incident reports, or CENTCOM statements on unsafe Iranian maneuvers; denial would be a continued pattern of only distant observation and radio warnings.
