Iranian frigate Sahand

Iranian frigate Sahand (in Persian سهند), a British-made Vosper Mark V class frigate (also known as Alvand class frigate), was commissioned as part of a four-ship order. The ship was originally called Faramarz, named after a character in Ferdosi's Shahnameh. However after the 1979 Islamic Revolution, it was renamed Sahand, after the Sahand volcano.

The Iranian Navy ship was sunk in Operation Praying Mantis on 18 April 1988. Located by two American A-6E Intruders of Attack Squadron 95 steaming roughly ten miles southwest of Larak Island, she was hit by two Harpoon missiles and two AGM-123 Skipper II laser-guided bombs. A pair of Rockeye cluster bombs from the aircraft and a single Harpoon from the USS Joseph Strauss (DDG-16) finished off the ship. Left heavily aflame, dead in the water and listing to port, the Sahand burned for several hours before fire reached her ammunition magazines and detonated, sinking the ship in over 200 meters (656 feet) of water southwest of Larak Island.

Iran is building a Moudge class ship named Sahand in memory of the original Sahand.
