Description
The 2S6 Tunguska 2K22 (NATO code SA-19 Grison) is a Russian-made self-propelled air defence system which combines gun and missile armament. The development of the 2S6 Tunguska began in 1970 after a request by the Russian army for a new self-propelled anti-aircraft weapon system to replace the old ZSU-23-4 self-propelled anti-aircraft gun. The first version entered service in 1986 were only four missiles, two either side, in the ready to launch position. The second version to enter service with the Russian army, and the current production model vehicle, is designated the 2S6M or 2K22M, he has eight missiles, four to each side of the turret. The Tunguska vehicle uses a tracked chassis GM-352M which is also used for the ground-to-air missile system Buk-M1 SA-11 Gadfly. A typical 2K22/2K22M battery would consist of six 2S6/2S6M self-propelled air defence vehicles, six reload vehicles and associated support and maintenance vehicles. The 2S6 Tunguska is intended to protect tank and motorized units from low-flying aircraft and helicopters, some types of cruise-missile, as well as to engage light armour ground targets and manpower of the enemy.
 
Variants
- 2S6: first version of the vehicle with four missiles, two either side of the turret.
- 2S6M: the production version with eight missiles
- 2S6M1: digital interface Ranzhir automated command-and-control system, new fire control system, new missile 9M311M with a maximum range of 10 km. Existing 2S6M Tunguska will be gradually upgraded to the new standard.

Armament
The turret of 2S6M Tunguska is mounted in the center of the chassis and armed with two 30mm 2A38 twin cannons, one to each side of the turret. The 30 mm 2A38M cannon are built by the Tulamashzavod Joint Stock Company; each is fired in turn to give a maximum rate of fire of between 1,950 and 5,000-rds/min. The high rate of fire allows effective engagement of fast-moving targets that are within the zone of fire even for short time. The high accuracy of laying owing to a stabilized line of fire and automatic target tracking makes the gun armament highly effective in engaging air targets, including firing on the move. The 30 mm (2A38M) cannon are water-cooled, gas-operated, electrically fired weapons and each barrel has an automatic muzzle velocity measuring device that feeds data to the fire-control computer. The cannons can fire two types of ammunition, HE-T ( High-Explosive Tracer) and HE-I (High-Explosive Incendiary), which are normally belted together both fitted with the A-670 impact/time fuze. Mounted outwards and below the 30 mm cannon is a bank of four 9M311 SAMs (Surface-to-Air Missile) in two blocks of two, which can elevate vertically independently of each other. The 9M311 can engage aerial targets with altitudes between 15 and 3,500 m and from 2,400 to 8,000 m in slant range with the target having a maximum speed of 500 m/s. Russian sources quote the crossover range as being up to 4,000 m. The 9M311 is a bi-caliber two-stage air defense missile with a separable solid-propellant booster. The missile 9M311 is highly agile which allows it to engage fast and maneuvering targets. It's guided by radio commands.
Design and protection
The hull and turret of the 2S6M Tunguska are made in all-welded steel armour which provides a protection against small arms firing and shell splinters. The driver is seated in the left front side of the chassis with the engine at the right. There are three crew members in the turret, the radar operator who is seated in the left front side of the turret, the commander on the right side and gunner to the rear in the centre.
Propulsion
The 2S6M is based on the tracked chassis of the GM-352M which is also for the Buk-1M (NATO reporting name SA-11 Gadfly) and `Tor' SAM ground-to-air defense missile systems. The hydro-pneumatic suspension consists of each side with six dual rubber-tyres road wheels with idler at the front, drive sprocket at the rear and three track-return rollers. A hydraulic track tensioning system is fitted as standard and this allows the driver to adjust the track tension without leaving his seat. The 2S6M Tunguska is motorized with a 4-cycle V12 water-cooled turbocharged diesel Model V-46-4 developing 780 hp at 2,000 rpm. The 2S6M Tunguska can run at a maximum road speed of 65km/h with a maximum road range of 500 km. The 2S6M Tunguska can negotiate a maximum vertical slope of 60% and side slope of 30%. It can cross a trench of up to 2 m width and vertical obstacle of 1 m. The 2S6M Tunguska can ford a depth of 0.8m without preparation.
Accessories
The 2S6M is equipped with E-band surveillance parabolic radar, which is mounted on the turret rear. This has a maximum detection range of 18 km. J-band tracking radar is mounted on the front of the turret. This has a maximum tracking range of 16 km. The complete radar system is designated the 1RL144M. When a target is detected by the surveillance radar at a range less than 8 km, this can be transferred automatically to the tracking radar on the front of the turret. The commander uses a console to select type of weapons and to then engage the target. The commander or the gunner can open fire. The radar operator has three consoles which he uses to control the tracking and fire-control radar which sends information such as range, bearing and elevation to the fire-control computer which in turn computes the laying commands for the weapons. Standard equipment of 2S6M Tunguska includes a heating system, 1V16 internal communications system, fire detection and suppression system, land navigation system, NBC system, night vision aids and internal and external communications equipment.
Combat use
The 2S6M Tunguska-M system battery comprises 2S6M combat vehicle (six in a battery), 9M311 air defense missiles (eight pieces for each launcher vehicle), 30mm artillery rounds and 2F77M transloaders (up to three in a battery), maintenance facilities and training aids.
