Three Iranian vessels harass a US Navy's Cyclone-class patrol ship in the straight of Ormuz

According to information published by the U.S. DoD on June 20, 2022, three fast attack crafts from Iran’s Islamic Revolutionary Guard Corps Navy (IRGCN) interacted in an unsafe and unprofessional manner as U.S. Navy ships transited the Strait of Hormuz.

Patrol coastal ship USS Sirocco (PC 6) and expeditionary fast transport ship USNS Choctaw County (T-EPF 2) were conducting a routine transit in international waters when three Iranian fast inshore attack craft approached.

One of the IRGCN vessels approached Sirocco head-on at a dangerously high speed and only altered course after the U.S. patrol coastal ship issued audible warning signals to avoid a collision.

The Iranian vessel also came within 50 yards of the U.S. Navy ship during the interaction, and Sirocco responded by deploying a warning flare.

The full interaction among all vessels lasted one hour and ended when the IRGCN craft departed the area. U.S. Navy ships continued their transit without further incident.
