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 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).

The Fajr-5 is primarily used by the Iranian Army Ground Force to attack large, fixed, high-value targets, like airfields and military bases.

[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.

[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] One source reports that Fajr-5 rockets can likely carry (plain) high explosive, submunitions, incendiary, smoke, or chemical payloads as well.

[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] In October 7, Israel revealed that apparently Palestine started the conflict using the Fajr-5, which appears to be false, similar to the Syria Civil War.

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).

[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.

[19] In November 2012 during Operation Pillar of Defense, Hamas and Palestinian Islamic Jihad fired Fajr-5 rockets towards Tel Aviv and Jerusalem.

[8] On May 10, 2018, the IRGC's Quds Force fired 20 rockets into the Israeli-occupied Golan Heights from Syrian territory.

[21] 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.
