Sources differ in recording characteristics of Parvin class vessels.
According to Jane's Fighting Ships, the ships have a standard displacement of 100 tonnes (98 long tons) and 150 t (150 long tons) at full load.[1] Conway's All the World's Fighting Ships puts the numbers at 105 tonnes (103 long tons) and 146 tonnes (144 long tons).[2]
The class design is 30.8 m (101 ft) long, would have a beam of 6.5 m (21 ft) and a draft of 2.5 m (8 ft 2 in) on the report of Jane's,[1] while Conway's mentions the dimensions as 30.5 m (100 ft) × 6.7 m (22 ft) × 3.1 m (10 ft).[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.[1] The system can reach a top speed of 15 knots (28 km/h) as stated by Conway's,[2] albeit Jane's mentions 22 knots (41 km/h).[1] The ranges given for the class are 1,140 nmi (2,110 km) at 17 knots (31 km/h)[1] and 1,500 nmi (2,800 km) at 10 knots (19 km/h).[2]
Original armament of the ships reportedly included five guns: 12.7mm and 20mm each two and one 40mm.[2] French sources give one 40mm and four 20mm machine guns, as well as a pair of Mk22 Mousetrap and DC racks.[2] As of 2015, they are reported to be armed with five guns consisting an old variant of Bofors 40 mm/60, a couple of Oerlikon GAI-BO1 20mm in addition to two 12.7 machine guns.[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.[1]
The original radar was model 303 of Decca Radar,[2] while the current surface search system is known to be working on I-band.[1] The sonar is a high-frequency hull-mounted active attack SQS-17B[1][2] but is allegedly unlikely to be serviceable per Jane's.[1]
Crew on each ship of this class totals 20 officers and men.[1][2]
