| The Shahab Thaqeb or Tagheb weapon system is a Iranian made short-range and low-altitude air defence missile system. This missile system was revealed in 1999. The main mission of the system is the intercepting of attacks from incoming flight targets. The Shahab Thaqeb is a dual role, high lethality 12 km, air defense missile with impressive self-defense anti-aircraft, has taken advantage of IR proximity fuse, 14 kg fragmentation warhead, and a good guidance accuracy. The Shahab Thaqeb is designed to be easily integrtaed with other host platforms. The Iranian Defence Industry has developing this air defence missile system based to French Thomson-CSF Airsys Crotale system which was captured during the Gulf War with Iraq. The technology of the Shahab Thaqeb comes also from the Chinese short range air defence missile system HQ-7 (FM-80). Most of the time, the Shahab Thaqeb operates with Oerlikon Contraves Skyguard radar fire-control and guidance system. The system has proven its accuracy, effectiveness, and ease operation when operated with a Sky Guard search and tracking system. Shahab Thaqeb and Sky Guard showed superior performance in acquisition and tracking during firing exercises against combat aircraft. |

| Missile support |
|
The Shahab Thaqeb air defence missile launcher is mounted on wheeled trailer. The configuration of the firing unit turret is similar to that of the French Crotale and Chinese FM-80 - a pedestal carrying two missile launch tubes mounted on either side of a centrally-mounted missile tracking radar and electro-optical device. Replacement missiles have to be reloaded manually using a truck- mounted crane, the technique used for Crotale and HY-7/FM-80.

The Shahab Thaqeb missile employs a radio command guidance system and it can fly at a speed of mach 2.2, guided by the rear and undetectable by the targets. The flight of the Shahab Thaqeb is guided according to the three point's method, also called the line-of-sight method (LOS). The Shahab Thaqeb is 2.93 m in length and weighs 85.1 kg. Improved countermeasures are fitted which allow the weapon to use a combination of radar/TV/infra-red command to line-of-sight guidance against low-level targets and radar/infra-red guidance against medium-altitude targets. Maximum effective range is stated to be 12,000 m against targets with velocities in excess of 400 m/s, 10,000 m against targets at 300 m/s and 11,000 m against rotary aircraft. Maximum effective engagement altitude is 5,500 m. The Single Shot Kill Probability using a single round is stated to be 0.8, which increases to 0.96 when a pair of missiles is used against a single target.

| Radar and control systems |
|
The Shahab Thaqeb air defence system operates with the Oerlikon Contraves Skyguard radar fire-control and guidance system. Iran took delivery of these radars a number years of ago to control its Oerlikon Contraves twin 35mm GDF-series towed anti-aircraft guns. The Swiss radar was developed to control ground-launched Sparrow surface-to-air missiles, so its known to be suitable for SAM applications. Operated by a crew of two, it is a trailer-mounted system whose sensor package consists of search radar, tracking radar and electro-optical devices that include a TV tracker.

| Combat use |
|
The Shahab Thaqeb air defence system cannot operate on the move but takes less than 5 minutes to become operational once it has stopped. Once the target has been detected the missile can be launched within about 5- 6 seconds. A single missile launch is claimed to have an 80% kill probability. and two missiles have a 96% kill probability with maximum target speed of up to 440m/sec. The Shahab Thaqeb has been Improved completely and equiped with laser range-finders and electro-optical systems.
