  • Iran continues its disruption strategy in the Strait of Hormuz, enabling selective access and limited transit.

  • The disruption strategy applies economic pressure while staying below the direct conflict threshold.

  • The transit reportedly followed a route between Larak and Qeshm Island, with vessels passing close to missile bases and a surveillance checkpoint.

  • The Iranian selective corridor poses a risk to oil tankers due to the water depth of under 25 m, suggesting the route may not relieve oil supply challenges. 

  • The arrival of two amphibious assault ships carrying roughly 5,000 Marines suggests a strategic shift in posture from immediate escort deployments to amphibious operations.

  • Airstrikes on strategic terrain such as Kharg, Abu Musa, Lesser Tunb, Greater Tunb, and the coast of Hormuz. 

  • The arrival of the 82nd Airborne in the Gulf.
