The Fajr-5 (rarely Fadjr-5,[4] Persian: فجر-۵, "Dawn") is an Iranian 333 mm long-range multiple launch rocket system (MLRS). The Fajr-5 was developed during the 1990s and has since been exported to various armed actors in the Middle East.

The Fajr-5 launcher fires four 6.48 meter long, 333 millimeter-calibre Fajr-5 artillery rockets, with a range of 75 kilometers (50 mi), weighing 915 kilograms each and carrying 175-kg fragmentation warheads with 90 kg of high explosive (HE). Most Fajr-5 rockets are unguided; in 2017 Iran introduced a variant, the Fajr-5C, which adds GPS guidance.

The Fajr-5 is primarily used by the Iranian Army Ground Force to attack large, fixed, high-value targets, like airfields and military bases.[2] In addition, the system is also used by militant groups to target Israel. Finally, the system has a niche role in use by the IRGC-N as an unguided anti-ship rocket system for the Persian Gulf.

Design

[edit]

MLRS

[edit]

The Fajr-5 artillery rocket system is installed on a Mercedes Benz 2631 6×6 forward control chassis.[5] To provide a stable firing platform, four hydraulically operated stabilizers are lowered to the ground before firing.[5] Another fully enclosed cabin to the immediate rear of the cab houses the remainder of the crew. This new chassis was unveiled in 2006;[5] some systems have not been upgraded and are still on older chassis.

The Fajr-5 is normally fired from this truck launcher, but it can also be fired individually.[6] The primary role of this artillery rocket system is the engagement of land targets. A naval surface search radar can be added to allow the system to be used in an anti-shipping role.[1]

Fajr-5 MLRS can be networked together,[1] and have a remote-fire capability in which the command vehicle can fire all nearby Fajr-5 systems.[1]

The Fajr-5's circular error probable (CEP) is not known.[1] The Fajr-5's reliability is not known. The Fajr-5's cost is not known. The number of Fajr-5 rockets produced is not known. Whether the Fajr-5 is still in production is not known.

In 2019, the Defense Intelligence Agency described the Fajr-5 as the "most capable" multiple rocket launcher in Iranian service.[7]

Rocket

[edit]

Basic rocket

[edit]

The rocket is solid fueled and has a fragmentation high explosive warhead.[2] The rocket is 6.485 meters long, 333mm in diameter, and weighs 907 kg.[2] It has wraparound fins for stabilization in flight, which reach a diameter of 710 mm when extended.[2] The rocket's double base propulsion burns for an average time of 5.3 seconds, reaching a peak velocity of 1100 m/s.[2] The rocket's motor has nine launch nozzles arranged in a circle, which are slanted to help create spin-stabilization in flight.[8] The Fajr-5 rocket carries a 175 kg warhead with a fragmentation radius of 500m.[2]

One source reports that Fajr-5 rockets can likely carry (plain) high explosive, submunitions, incendiary, smoke, or chemical payloads as well.[1] The shelf life of a basic Fajr-5 rocket is 15 years.[2]

Two-stage rocket

[edit]

Iran produces a two-stage Fajr-5 rocket with extended range. The two-stage Fajr-5 rocket has a length of 9.4 m and a maximum range of 180 km at sea level.[2] This variant has a diameter of 333 mm, like other Fajr-5 rockets, but has fixed fins, which have a diameter of 561 mm.[2] The two-stage Fajr-5 can reach a maximum altitude of 85 km and carries the same 175 kg warhead with a 500m fragmentation radius.[2] This variant is launched from TELs similar to those used for Zelzal rockets, which only have the capacity for a single rocket.

The shelf life of a two stage Fajr-5 rocket is 15 years.[2]

Fajr-5C

[edit]

In February 2017, Iran revealed a guided version of the Fajr-5, similar to the Chinese SY300, under the name Fajr-5C. It has a firing accuracy of 250 m when using INS and 50 m using GNSS, with range from 40–130 km (25–81 mi).[9]

The guided Fajr-5 rocket was briefly mentioned, and believed to be under development, in 2014.[10] The missile has been delivered to the IRGC Ground Force units as of May 2023.[11]

GR110/GF5LR1

[edit]

In August 2023, Iran revealed a new version of the Fajr-5 at the Ministry of Defense Industry Authority Exhibition 1402.

It has a maximum range of 110km and a weight of 902kg with a warhead weighing 115kg while achieving an accuracy of 25m CEP.

Reloading

[edit]

When the Fajr-5 is reloaded, the launch tubes (in two groups of two) are detached from the launcher and laid on the ground by a crane (an Italian Effer 155-25). Then, a machine called a "Loading machine" is used to mechanically press the heavy Fajr-5 rockets into their launch tubes one by one. When all the tubes are filled, the crane is used to reattach the launch tubes to the vehicle.[2] Because of the long reload time and large size of the "Loading machine" (12m), the Fajr-5 MLRS is supposed to retreat after firing to safer rear battle areas to reload.[2][failed verification] A reload takes 2 minutes per rocket.[2]

History

[edit]

The first Fajr-5 were created when China exported WS-1 MLRS to Iran in the late 1980s/early 1990s.[12] They were then subsequently created and produced by Iran's Aerospace Industries Organization.

Operational history

[edit]

Iran

[edit]

As of 2011, the best estimate for the number of Fajr-5 pieces manufactured was "somewhere around 100" or less.[1]

Lebanon

[edit]

Iran supplied a number of Fajr-5s to Hezbollah in Lebanon beginning in 2002[13][14] or 2001.[15] Sources disagree on whether Hezbollah used Fajr-5 rockets in the 2006 Lebanon War,[16] in part because at the time they were confused with similar Khaibar-1 rockets.

Palestinian territories

[edit]

Fajr-5 rockets are held in the Gaza strip by Palestinian militant groups. The first was fired by Hamas in November 2012.[17] It is believed that manufacture of some sub-components and final assembly may take place in Gaza, but that the critical components of the rocket are furnished by Iran.[8] Iran denied transferring any rockets to Gaza but said they instead transferred technology to manufacture the rocket.[18]

Some Palestinians have named their children after the Fajr-5.[19]

Pillar of Defense

[edit]

In November 2012 during Operation Pillar of Defense, Hamas and Palestinian Islamic Jihad fired Fajr-5 rockets towards Tel Aviv and Jerusalem. At least 14 rockets were fired in total.[8]

Syria

[edit]

On May 10, 2018, the IRGC's Quds Force fired 20 rockets into the Israeli-occupied Golan Heights from Syrian territory. Some of these were Fajr-5s.[20]

In December 2018 some Fajr-5 rockets were destroyed in an IAF airstrike.[21]

Iraq

[edit]

Sporadically, during the US occupation of Iraq (between 2003 and 2011), Iranian Backed militias fired the 333 Fajr-5 at US forces from fabricated rails. In 2015, Iran sent Fajr-5 rockets and launcher systems to Iraq to be used in the War against the Islamic State. It is unknown if they were fired, and the quantity sent is also unknown.[22]

Yemen

[edit]

The Houthis have unveiled a rocket with similarities to the Fajr-5.[23]
