2K22 Tunguska

The 2K22 Tunguska was created after Soviet planners concluded that gun-only short-range air defense was no longer enough against attack helicopters and fast aircraft. It replaced the ZSU-23-4 concept with a combined gun and missile system able to engage targets at different ranges. The result was a highly mobile air-defense vehicle intended to accompany maneuver forces.

Tunguska mounted high-rate 30 mm cannon, surface-to-air missiles, search radar, tracking radar, and electro-optical equipment on a tracked chassis. The guns covered close and fleeting targets, while missiles extended reach against helicopters and aircraft. This integrated arrangement reduced the gap between missile minimum ranges and gun maximum ranges in front-line air defense.

Tunguska entered Soviet and later Russian service as a battalion- or regimental-level air-defense asset and was exported to several operators. Its concept anticipated later systems such as Pantsir, which also pair missiles and rapid-fire guns. The system's importance lies in how it adapted Soviet mobile air defense to the helicopter and precision-strike threat of the late Cold War.
