The Alvand class (also called the Saam class frigate or the 'Vosper Mk 5 type) comprise four Iranian light patrol frigates. Only three are currently in service, although Jane's Fighting ships 2006-07 reports that the wreck of the Sahand is being re-built.

The United Kingdom built all four ships which were originally armed with nine Sea Cat anti-air missiles and five Sea Killer anti-ship missiles. Iranian Navy has replaced the missiles with Chinese variants.

One Alvand-class frigate, the Sahand, was sunk by U.S. forces during Operation Praying Mantis in 1988 after unsuccessfully firing upon an A-6 Intruder flying from the USS Enterprise. It was then struck by Harpoon missiles from this aircraft, and then a coordinated Harpoon attack from its wingman and a nearby surface ship.
