The Alvand class (Persian: کلاس الوند) or Saam class (Persian: کلاس سام) was originally a class of four frigates built for the Imperial Iranian Navy. They were renamed after the Iranian Revolution, and served in the Islamic Republic of Iran Navy during Iran-Iraq War. Three still remain in service. A fourth was sunk by the U.S. Navy in 1988.
