STRAIT OF HORMUZ (May 10, 2021) Two Iranian Islamic Revolutionary Guard Corps Navy (IRGCN) fast in-shore attack craft (FIAC), a type of speedboat armed with machine guns, conducted unsafe and unprofessional maneuvers while operating in close proximity to USCGC Maui (WPB 1304) as it transits the Strait of Hormuz with other U.S. naval vessels, May 10. U.S. forces exercised lawful defensive measure after the IRGCN vessels ignored repeated verbal and acoustic warning and closed toward Maui at a high speed and close distance with weapons uncovered and manned.
