Jamaran (frigate)

Jamaran is the name of a domestically produced Moudge class guided missile frigate  launched in early 2010 in Bandar-e-Abbas, Iran. Iran said that the design and building of Jamaran and the missile boat IRANIAN MISSILE BOAT Paykan were among the greatest achievements of the Iranian Navy and the ship's launch marks a major technological leap for Iran's naval industries. It is the first ship from four in its class. More ships in its class are under construction to be added to the Iranian Naval fleets in the Caspian Sea and the Persian Gulf soon. The ship is designed for a crew of 140. The Jamaran class combines anti-submarine assets with other systems of weapons capable of dealing with surface and air threats as well.

Weapons systems
The primary weapon deployed by Jamaran-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 Jamaran-class also carries a close-in anti-submarine torpedo system, the 324 mm light torpedo with 30 km 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 Jamaran-class has four medium range Fajr Surface to Air Missiles (reverse engineering of RIM-66/SM-1 standard missile) with 74 km range, and 24.4 km flight ceiling, mounted in box launchers at the deck above the main deck level in front of the helicopter landing pad. The Jamaran-class also carries two 20 mm manned Oerlikon cannons and a 40 mm Fateh-40 autocannon (reverse engineering of Bofors L/70) with 12.5 km 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 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 kilometers towards aerial targets. The Fajr-27 is a multi-purpose weapon, capable of dealing with surface, air, and onshore targets. The Jamaran has room on the roof of the upper deck level for installing 2 × 0.50 cal machine guns in the future.

Countermeasures
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 aircondition system with impenetrability and ressistance capability during these attacks, Automated navigation system and some other systems.

Propulsion
The Jamaran-class vessels are powered by two 10,000 hp engines, and uses four diesel generators which each generate 550 kW. The Jamaran-class can reach a maximum speed of 30 knots.

Helicopter Landing Platform
The Jamaran can accommodate a medium size 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 the 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".
