The 2K22 Tunguska (Russian: 2К22 "Тунгуска"; English: Tunguska) is a Russian tracked self-propelled anti-aircraft weapon armed with a surface-to-air gun and missile system. It is designed to provide day and night protection for infantry and tank regiments against low-flying aircraft, helicopters, and cruise missiles in all weather conditions. Its NATO reporting name is SA-19 "Grison".
Development of the system started on 8 June 1970, at the request of the Soviet Ministry of Defence the KBP Instrument Design Bureau in Tula under the guidance of the appointed Chief Designer AG Shipunov started work on a 30 mm anti-aircraft system as a replacement for the 23 mm ZSU-23-4.
 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, guidance and navigational systems by VNII "Signal" and optics were developed by the Leningrad Optical Mechanical Association LOMO.
 However development was slowed between 1975 and 1977 after the introduction of the 9K33 Osa missile system, which seemed to fill the same requirement but with greater missile performance. After some considerable debate it was felt that a purely missile based system would not be as effective at dealing with very low flying attack helicopters attacking at short range with no warning as had been proven so successful in the 1973 Arab-Israeli War. 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 missiles by replacing the eight-beam laser proximity fuze with a radio fuse. Additional modification afforded greater resistance to infrared countermeasures 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 gun and missile system entered production at KBP—a descendant of the Tunguska, the Pantsir system offers even greater performance than its predecessor.
