Open-source and U.S. intelligence reporting indicate Iran retains sufficient asymmetric assets (mines, drones, fast attack craft) to disrupt commercial transit through the Strait of Hormuz despite recent degradation of larger naval and missile platforms. CIA assessments assess Tehran can sustain a naval blockade for 90-120 days using stockpiles and smuggling networks. Current incidents show continued IRGC capacity of harassment of U.S. warships.
