Development

Development of the system started on 8 June 1970, at the request of the Soviet Ministry of Defence the KBP Instrument Design Bureau

The project which was given the designation "Tunguska" was a response to the observed shortcoming of the ZSU-23-4 (short range and no early warning) and a counter to new ground attack aircraft in development such as the A-10 Thunderbolt II

 which was designed to be highly resistant to 23 mm cannons. Studies were conducted and demonstrated that a 30 mm cannon would require two-to-three times fewer shells to destroy a given target than the 23 mm cannon of the ZSU-23-4, and that firing at a MiG-17 (or similarly at, in case of war, NATO's Hawker Hunter or Fiat G.91) flying at 300 m/s, with an identical mass of 30 mm projectiles would result in a kill probability of 1.5 times greater than with 23 mm projectiles. An increase in the maximum engagement altitude from 2,000 to 4,000 m and increased effectiveness when engaging lightly armoured ground targets were also cited.

The initial requirements set for the system were to achieve twice the performance in terms of range, altitude and combat effectiveness than the ZSU-23-4, additionally the system should have a reaction time no greater than 10 seconds. Due to the similarities in fire control of artillery and missiles it was decided that Tunguska would be a combined gun and missile system. By combining guns and missiles, the system is more effective than the ZSU-23-4, engaging targets at long-range with missiles, and shorter range targets with guns.

In addition to KBP as the primary contractor other members of the Soviet military industrial complex were involved in the project, the chassis were developed at the Minsk tractor factory, the radio equipment at the Ulyanovsk Mechanical Factory Ulyanovsk

. Since the reaction time of a gun system is around 8–10 seconds, compared to the reaction time of missile-based system, approximately 30 seconds, development was restarted.

The initial designs were completed in 1973 with pilot production completed in 1976 at the Ulyanovsk Mechanical Factory. System testing and trials were conducted between September 1980 and December 1981 on the Donguzskom range. It was officially accepted into service on 8 September 1982 and the initial version designated 2K22/2S6, with four missiles in the ready to fire position (two on each side). The Tunguska entered into limited service from 1984 when the first batteries were delivered to the army.

After a limited production run of the original 9K22, an improved version designated 2K22M/2S6M entered service in 1990. The 2K22M featured several improvements with eight ready-to-fire missiles (four on each side) as well as modifications to the fire control programs, missiles and the general reliability of the system.

Tunguska underwent further improvement when in 2003 the Russian armed forces accepted the Tunguska-M1 or 2K22M1 into service. The M1 introduced the new 9M311-M1 missile which made a number of changes allowing the 2K22M1 to engage small targets like cruise missile

s by supplementing the missile tracking flare with a pulsed IR beacon. Other improvements included an increased missile range to 10 km, improved optical tracking and accuracy, improved fire control co-ordination between components of a battery and the command post. Overall the Tunguska-M1 has a combat efficiency 1.3–1.5 times greater than the Tunguska-M.

The Tunguska family was until recently a unique and highly competitive weapons system, though in 2007 the Pantsir

 index, though the army designation 9K22 is a valid alternative. A complete system or battery consists of six 2S6 combat vehicles armed with the 9M311 "Treugol'nik" (triangle) surface-to-air missile and two 2A38 30 mm cannon. These are accompanied by up to three 2F77 transloader trucks. The 9K22 is also associated with a variety of support facilities including the 2F55-1, 1R10-1 and 2V110-1 repair and maintenance vehicles, the MTO-AGZ workshop and the 9V921 test vehicle. These facilities provide maintenance for the 9K22 battery in the field as well as scheduled overhauls.

The 2S6 combat vehicle uses the GM-352 and later GM-352M chassis developed and produced by the Minsk Tractor Plant (MTZ) which has six road wheels with hydropneumatic suspension on each side, a drive sprocket at the rear and three return rollers. The chassis are capable of fording to a depth of 0.8 meters, climbing gradients of up to 60% and side slopes of 30%. The GM-352 can cross a one meter vertical obstacle and a two meter trench. An NBC

A battery of six Tunguska can automatically receive fire control information via an encrypted radio link, this allows targets to be distributed between individual units from a Ranzhir or PPRU battery command post, which can receive target information from either AWACS or early warning radar or in the case of the PPRU its own radar equipment.

Variants

  • 2K22: Original system, with 9M311 (3M87), 9M311K or 9M311-1 missiles. Some of these early versions of the "Tunguska" system were known as "Treugol'nik" (Russian Треугольник—triangle). This system is mounted on the 2S6 integrated air defence vehicle.
  • 2K22M (1986): Main production system, with 9M311M (3M88) missiles. This integrated air defence vehicle 2S6M is based on the GM-352M chassis.
  • 2K22M1 (1988): Improved version with the 2S6M1 combat vehicle on a GM-5975 chassis, using the 9M311-M1 missile (range: 10 km) and with an improved fire control system. Passed state trials in April 2003 and entered service with the Russian armed forces a year later.
  • 2K22M with 57E6: Complete upgrade of system with new 57E6 missile and new radar system, with detection range of 38 km and a tracking range of 30 km. Missile range is increased to 18 km.


Guns

The dual 2A38 30 mm cannons and the later 2A38M were designed by the KBP Instrument Design Bureau and manufactured by the Tulamashzavod Joint Stock Company. The cannons are fired alternatively with a combined rate of fire of between 3,900 and 5,000 rounds per minute (1,950 to 2,500 rpm for each gun), and have a muzzle velocity of 960 m/s. Bursts of between 83 and 250 rounds are fired as determined by the target type, with an engagement range between 0.2 and 4.0 km and to an altitude of 4 km. HE-T and HE-I shells are used and fitted with a A-670 time and impact fuze

 which includes an arming delay and self destruct mechanism. The cannons can be elevated and depressed to +87 to -10 degrees and as such can be used to engage ground as well as aerial targets. The 2K22 can fire its cannons in two primary modes of operation, radar and optical, in radar mode the target tracking is fully automatic, with the guns aimed using data from the radar. In optical mode the gunner tracks the target through the 1A29 stabilized sight, with the radar providing range data. The 9K22 is reported to have a kill probability of 0.8 with cannon.

Missiles

The system uses the same 9M311 (NATO: SA-19/SA-N-11) missile family as the naval CIWS Kashtan
Kashtan
Kashtan is surname of:* Dror Kashtan , Israeli footballer and manager* William Kashtan , general secretary of the Communist Party of Canada- See also :* Kashtan CIWS * Kasztanka* Castanea* Kastania...

 which can engage targets at a range of 2.4 to 8 km and to an altitude of 3.5 km, the Tunguska-M1 uses the improved 9M311-M1 missile with an increased range of 10 km. The missile has two stages, a large booster stage with four folding fins, which boosts the missile to a velocity of 900 m/s, before falling away. The second stage has four fixed fins, and four steerable control surfaces. The complete missile is around 2.56 meters long with a weight of 57 kg.

Guidance is performed by the gunner who uses the 8× magnification (8 degree field of view) 1A29 stabilized sight of the Tunguska to track the target and the missile (using a flare or pulsed beacon) is automatically tracked by the optics. The deviation of the missiles compared with the tracked target is used to calculate guidance commands, the tracking radar being used to send radio commands to the missile, making Tunguska a semi-automatic, radio command, with optical line of sight

 system, consisting of 600 mm long 6 to 9 mm diameter rods with a flower-like cross section. The cross section ensures the rods break into fragments weighing 2–3 grams. The rods form a complete ring about 5 m from the missile. Outside the rods is a fragmentation layer of steel cubes weighing 2–3 grams. The 9K22 is reported to have a kill probability of 0.6 with missiles (9M311).
