Key Data

Type Multi purpose guided missile frigate / destroyer
Builder Marine Industries Group
Operator Iranian Navy
Crew 120-140
Speed 30kt
Displacement 1,420t
Length 94m


Jamaran is the first indigenously built Mowj Class multi-purpose guided missile frigate of the Imperial Iranian Navy. Currently being built by the Marine Industries Group of Defense Industries Organization (DIO), the vessels are locally referred to as destroyers.
The keel for the first vessel, Jamaran, was laid down in 2006. Jamaran was launched in February 2007 and commissioned in February 2010, and is stationed at the Bandar-e-Abbas naval base. The construction of the second frigate, Velayat, commenced in February 2010. It is expected to be commissioned by 2012.

Jamaran multi-purpose guided missile frigate design
The design of the Mowj Class frigate is based on the Alvand Class (Vosper Mk 5) light patrol frigates. The hull form of the vessel does not feature radar signature reducing properties. The displacement of the vessel is 1,420t, which is similar to the size of a light frigate.
The Jamaran warship, which can also be referred as a corvette due to its low displacement, incorporates anti-submarine warfare and other weapon systems to defend surface and air threats. It can accommodate a crew of 120 to 140.
The overall size of the Jamaran is smaller in comparison with the similar warships in its class. The vessel has an overall length of 94m, a breadth of 10m and a draft of 3.1m.

"Jamaran is the first indigenously built Mowj Class frigate of the Iranian Navy."



Jamaran frigate missions
The Jamaran frigates are deployed in range of missions, including surveillance in national territorial waters, early warning, anti-submarine warfare, surface-to-surface and surface-to-air warfare and amphibious operations.
In February 2010, Jamaran accomplished its maiden mission in the waters of the Persian Gulf. The vessel successfully fired missiles against imaginary targets.

Jamaran missiles
Jamaran is armed with Noor long-range anti-ship missiles, four of which are housed in box launchers mounted on the roof of the upper deck level between the radar and main mast. The single-shot kill probability of the missile is as high as approximately 98%.
Iran successfully test-fired the missile from the Jamaran frigate in March 2010. Noor can hit the targets within a range of 200km and is powered by a Toloue-4 engine.
The Mowj Class has four SM-1 surface-to-air missiles for aircraft self-defence. These missiles are fired from box launchers fitted at the main deck close to the helipad.
A new surface-to-surface missile, named the Nour, was test fired from the Jamaran destroyer in March 2010. Launched in the waters of the Persian Gulf, the test was successful with the missile having hit its target from a distance of 100km. Iran is also planning to build an upgraded missile with a 300km range.

Frigate torpedoes
The Jamaran frigate is equipped with a close-in anti-submarine weapon system. Two triple torpedo launchers on either side of the stern can launch 324mm light torpedoes.

Mowj Class guns
The Mowj Class is fitted with two 20mm manned cannons and a 40mm automatic cannon, providing shipboard point-defence against incoming anti-ship missiles and aircraft.
The main gun, a 76mm Fajr-27, is fitted on the forecastle. The Fajr-27 is a multi-purpose gun, which can be used against surface, air and onshore targets. The gun has a range of over 17km and can fire at a rate of 85 rounds per minute.

Jamaran helicopter system
Jamaran is the first helicopter-capable surface combatant of Iran. The flight deck of the frigate accommodates an AB 212 anti-submarine warfare (ASW) helicopter and allows helicopter in-flight refuelling (HIFR) operations. The AB 212 is equipped with a low-frequency variable depth sonar and radars to track the submarines at long range

Jamaran sensors / radars
The sensor suite of the frigate includes a Plessey AWS-1 long range air/surface search and tracking radar, and two navigation radars. Plessey AWS-1 is fitted on the roof of forward of the funnel, while navigation radars are installed on the main mast. Jamaran is also equipped with a fire control radar, which is identical to the one on the Alvand Class frigate.

Jamaran propulsion
The Jamaran Class destroyers are powered by two 10,000hp diesel engines in addition to four diesel generators, which provide auxiliary power. Each genset is rated at 550kW. The propulsion system provides a maximum speed of 30kt

Actually 2 SAM missiles are not enough! because of powerful air forces of our enemies i think we should work on vertical lunching systems which make naval vessels able to carry lots of missiles in different types. i think this technology could be obtained from our tor missile systems which utilize this method for lunching. almost modern naval vessels uses this method. for example Korean navies KDXIII destroyers are able to carry about 80 SM-2 Block IIIB missiles in it's Mk 41 VLS lunching cells!!! moreover these vessels are armed by 48 VLS cells for lounching cruise missiles! if you want to fight in sea you most be heavily armed

yeah its surly is as u say. but i thing we are way far from that technolegy(vertical lunch).tor is a good thing to start for our navy.but at least they could place more missiles for AA combat. just like jamaran1.i never closely looked at velatat to see what is the exact deffrence betwwen these two ships that coused the velayat to have 2 less missiles! what more equipments are in velayat that coused this less spacing???

Till the development of VLS systems, launchers similar to Mk-26/13/22 for RIM-66/harpoon and launcher of 3s-90 (shtil) missiles that have a magazine and can be reloaded automatically, are good solution for launching Mehrab/Raad-1 or even Qader/Noor missiles on Mowj class frigates.

The only problem is availability of enough room for implementing such system.

now that what im talking about guys! look at the secend image. the double luncher. this is a good system until our navy make the VLS sys operational. but the question is: is this so hard to design and build? it looks simple. its jus a stand to lunch the missile. and it realy have less spacing compare to box sys in velayat figate. is that right? and i ask again:
what is the exact deffrence betwwen these two ships that coused the velayat to have 2 less missiles! what more equipments are in velayat that coused this less spacing???

As all of us know, VLS is the best choice, less occupied room, faster response and higher fire power and less weight.

If any project for development of a VLS is underway now, its better to wait for that VLS system, but in the case of facing major technical problem for development of VLS that needs long time and high costs, its good to develop such non-VLS launchers. The problem for using such launchers on Mowj class is availability of enogh internal room in Mowj frigates for magazine and auto-loader of such launchers. In the case of avalability enough internal room , It can be placed behind Fath gun or may be in current position of Mehrab missile launchers on Jamaran-2.


Most likely Iranian experts are developing a VLS for Bavar-373 now, Likely the technology used for launcher of sub-surfaced launched anti ship cruise missiles can be used for development of a VLS too.

actually I think it's not the time to discuss about VLS and the quantity of available AA missiles in our country made vessels , because as the first step , we have to build bigger vessels , much bigger than this to HAVE enough space for storing the missiles and reloading systems in the body


i think they're building a bigger ship (i don't know in what stage they are) about 2000 tons , for navy in Bandar-e Abbas , I think that project would be a big improvement

now that the purpose is designated , and we have stepped on the way to elate our flag in oceans , more than warships , we need some logistics ships , like IRINS Kharg , now that we can build 30.000 ships simply (oil tankers) , we should build some ;)


yet , with all these , I think in next 10 years we would reach many summits and most of the issues we talk here about Martial technology would be solved :applause:

however our navy is getting better and better we most be pragmatic. we most develop our fleet step by step for example utilizing phased array radar in moudge 2 or velayat is a real rise in our navy. I hope navy designers work on bigger vessels which could be equipped better and i hope they replace this radar reflector hull with a nice stealth one!!! I hope

well we are doing good regarding naval tech . the missions for our ships would be sth like: 1- our big naval ships would secure our interests in blue waters and will also provide a great fire power against foreign navies , this for sure includes united states

2 - our small crafts like fast boats or semi-heavy or light subs to defend the naval borders as they are so effective and stealth


we also shouldnt forget the missiles that we have ...


our navy is becoming a blue water navy so we should expect great big achievements in long term

today we can surely defend our coasts BUT :

we shouldn't consider being blue water sth easy. it needs decades of hard work and cold money! for near future, the ability to reach international trade routes of Indian ocean would be enough for us

and this needs many destroyers of which we have none yet .

dear , iran already has short term plans to send warships to us coasts as u know .


this is called a blue water navy


i got your point , its wise but inconsiderate


you should consider the ongoing plans like sabalan which will totally shift our position in blue waters from a non-present country to an active one

haman my friend

any vessel larger than a certain amount can be considered ocean going and can reach U.S. coasts, but this is not considered blue NAVY.

whats more a powerful navy is not only warships

it needs bases, logistics, communication, research and development, industrial capacity and etc.


yes there is shortcuts for defending yourself, specially with Iranian tactics, but a ful scale blue navy that can project power is a different story,
