Islamic Republic of Iran Navy (IRIN)

Force in Play

Surface fleet largely destroyed; headquarters demolished

The last time the United States sank Iranian warships was April 18, 1988. Thirty-eight years later, American forces destroyed nine Iranian naval vessels in a single day and demolished the country's naval headquarters at Chabahar, on the Gulf of Oman. The strikes came after Iran attempted to blockade the Strait of Hormuz, the 21-mile-wide passage through which roughly one-fifth of the world's oil supply flows, broadcasting radio warnings that no commercial ship would be allowed to pass.
