The Parvin (Persian: پروین) is a class of large patrol craft operated by the Islamic Republic of Iran Navy.

They ships in the class are modified versions of PGM-71 vessels, all built by the American shipyard Peterson Builders.

[2] Both sources agree that the ships are powered by eight General Motors diesel engines totaling 2,040 horsepower (1.52 MW) that rotate a pair of shafts, but the engine models are variously cited GM 8-71[2] and GM 6-71.

[2] French sources give one 40mm and four 20mm machine guns, as well as a pair of Mk22 Mousetrap and DC racks.

[1] They are also equipped with four racks of depth charge (with eight US Mk 6), and two missile launchers of unknown type are installed on them after refit.
