Iranian frigate Jamaran

Weapons systems

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. 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. The single shot hit probability of the Noor, with a range of 170 km, is estimated to be as high as 98%. 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) 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. The main gun on the forecastle is a 76 mm (3 in) Fajr-27 gun. 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.

Countermeasures

Jamaran possesses chaff and flare systems and electronic warfare capabilities.

Sensors & Equipment

The ship is equipped with one Plessey AWS-1 long range air and surface search and tracking radar, installed on the roof of forward of the funnel. The ship is also fitted with two navigation radars on the main mast. The ship is also 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.

Propulsion

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).

Helicopter Landing Platform

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.

Classification

While Jamaran has been described by the press as a guided missile destroyer, within some western military analysis circles such as Jane's Information Group and Globalsecurity.org it has instead been designated a frigate based on its displacement; the latter acknowledged that there are no "rules in these matters". Furthermore, Globalsecurity.org states: 'Iran calls these ships "destroyers" but they would be classed as a light Frigate by the reckoning of all other countries.' PressTV and Iranian military are themselves describing Jamaran as a "frigate class ship" in the same article where they claim it as a "destroyer".
