Iranian frigate Jamaran

The primary weapon deployed by Moudge-class vessels is the Sikorsky SH-3 Sea King, which acts in concert with shipboard sensors to seek out and destroy submarines at long range. The Moudge class also carries a close-in anti-submarine torpedo system, a 324 mm (13 in) light torpedo with a 30 kilometres (19 mi) range, mounted in triple torpedo launchers on either side of the stern.[11]

To deal with surface forces, the vessel is equipped with four Noor / C-802 surface-to-surface anti-ship cruise missiles, mounted in box launchers on the roof of the upper deck level between the radar and the main mast pointing towards either sides.[7][12][13] The single shot hit probability of the Noor, with a range of 170 km (110 mi), is estimated to be as high as 98%.[14]

For anti-aircraft self-defense the Moudge class has four medium range Fajr surface-to-air missiles (reversed engineered from the RIM-66/SM-1 standard missile)[15] with 74 km (46 mi) range, and 24.4 km (15.2 mi) flight ceiling, mounted in box launchers at the deck above the main deck level in front of the helicopter landing pad. The Moudge class also carries two 20 mm manned Oerlikon cannons and a 40 mm Fateh-40 autocannon (reverse engineered from Bofors L/70) with 12.5 km (7.8 mi) aerial range, to provide a shipboard point-defense against incoming anti-ship missiles and aircraft.[16]

The main gun on the forecastle is a 76 mm (3 in) Fajr-27 gun.[4] The gun is capable of firing at a rate of 85 rounds per minute at a range of more than 17 kilometers towards surface targets and 12 km (7.5 mi) towards aerial targets. The Fajr-27 is a multi-purpose weapon, capable of dealing with surface, air, and onshore targets. Jamaran has room on the roof of the upper deck level for installing two 0.50 calibre machine guns in the future.[13]

Jamaran possesses chaff and flare systems and electronic warfare capabilities.[17]

The ship is equipped with one Asr passive electronically scanned array long-range radar for air and surface search and tracking, installed on the roof of forward of the funnel.[5] The ship is also fitted with two navigation radars on the mainmast. The ship is equipped with one fire control radar.

The ship's equipment in detail are: S and X band radars, tactical aviation radar, radar processor and fire control systems, subsurface sonar and echo sounder, surface and subsurface communication & internal communication and computer network systems, ECM, ECCM, and navigation systems, electroptical and stabilizer and synchronizer systems, alert system against chemical-microbial attacks and doors and air conditioning system with impenetrability and resistance capability during these attacks, Automated navigation system and some other systems.

The Moudge-class vessels are powered by two 7,500 kW (10,000 hp) engines, and uses four diesel generators which each generate 550 kW (740 hp). The Moudge class can reach a maximum speed of 30 kn (56 km/h; 35 mph).

Jamaran can accommodate a medium-sized helicopter and can also run a helicopter in-flight refueling (HIFR) operation when a helicopter approaches on the landing platform, which is not necessarily suited for landing operations.[18]

On 11 May 2020, reports stated that Jamaran was conducting a test on a new anti-ship missile which mistakenly locked onto and hit the nearby friendly Iranian support vessel Konarak. The Iranian Navy reported 19 sailors dead and 15 others injured in the incident, which took place during a naval exercise in the southern region of Iran near the Straits of Hormuz.[20]
