## Prediction

With Iran declaring the Strait of Hormuz closed, expect an immediate forward deployment and visible maneuvering of U.S., UK, and Gulf naval assets at the strait’s eastern and western approaches within 24 hours. Initial confrontations are likely to take the form of aggressive maneuvering, warning shots, and attempted interdictions of tankers rather than immediate ship-to-ship missile engagements. This will test rules of engagement, heighten miscalculation risk, and force commercial operators to decide whether to await escorted convoys or reroute entirely. Confirmation would be AIS/imagery evidence of coalition surface combatants massing near Bandar Abbas, Qeshm, and the Musandam peninsula and formal NOTAMs/NavWarnings restricting transit; denial would be rapid, negotiated Iranian clarification that “closure” is symbolic and that escorted transit continues.

## Drivers

- Flash report that Iran has closed the Strait of Hormuz and launched missiles
- Broad U.S. strikes on Bandar Abbas, Qeshm Island, and IRGC naval bases
- Historical U.S. pattern of deploying surface groups to secure chokepoints in crises
