Theater: Strait of Hormuz
Time horizon: 24h

Moderate confidence (65%)
Risk direction: escalatory · Impact: HIGH
Full prediction
In the next 24 hours, at least one additional close encounter between US naval or unmanned vessels and IRGC assets is likely in or near the Strait of Hormuz, though both sides will try to avoid a mass-casualty event. Expect aggressive maneuvering, lasing, warning shots, or non-lethal attempts to interfere with drones and unmanned surface vessels. Such actions increase miscalculation risk and could trigger rapid US retaliatory strikes on IRGC boats or shore positions if a US crewed asset is threatened. Confirmation would be new Pentagon or IRGC statements about unsafe interactions or minor skirmishes; disconfirmation would be conspicuous mutual messaging emphasizing deconfliction and a visible reduction of US unmanned platforms in the chokepoint.
