Iranian frigate Sahand (Persian: سهند) was a British-made Vosper Mark V class frigate (also known as the Alvand class) commissioned as part of a four-ship order. She was launched in 1969. The ship was originally called Faramarz, named after a character in Ferdowsi's Shahnameh. After the 1979 Islamic Revolution it was renamed Sahand, after the Sahand volcano.
