India Signs $47M Deal for Russian Tunguska Air Defense to Counter Drones and Missiles.

India moved to close a critical gap in its air defenses on March 27, 2026, signing a $47 million deal with Russia’s JSC Rosoboronexport to acquire Tunguska air defense missile systems in New Delhi. The purchase delivers a mobile, dual gun-and-missile capability designed to intercept aircraft, drones, and low-flying cruise missiles in real time.

The acquisition sharpens India’s short-range air defense at a time of rising aerial threats, giving ground forces a layered shield against fast, low-altitude attacks. By integrating combined firepower on a single platform, the Indian Army gains faster response times, greater engagement flexibility, and stronger protection for frontline units in contested environments.

The agreement was formalized at Kartavya Bhawan-2 in the presence of Defence Secretary Rajesh Kumar Singh, thereby reinforcing India’s layered air defense architecture amid rapidly evolving aerial threats. The procurement directly enhances battlefield survivability of forward-deployed units and deepens Indo-Russian defense industrial cooperation.

India’s ground-based air defense network is structured as a dense, multi-layered system exceeding 728 surface-to-air missile systems, designed to defeat threats across altitude and range bands. At the medium range, the indigenously developed Akash SAM provides area defense with engagement ranges of 25–30 km, supported by phased-array radar and integrated command networks. The legacy 2K12 Kub system continues to supplement this layer, offering additional medium-range coverage and redundancy in critical sectors.

The short-range and point-defense layer, comprising more than 500 systems, forms the backbone of protection against low-altitude and high-speed threats. The 9K33 Osa-AKM provides autonomous, radar-guided interception capability on a mobile platform, while the 9K31 Strela-1 and 9K35 Strela-10 deliver highly mobile low-level air defense. Man-portable systems such as Igla-1 and Igla extend coverage to dispersed units, and the Starstreak missile introduces a very high-velocity interception capability against fast jets and UAVs, particularly in counter-drone roles.

Within this architecture, the 2K22 Tunguska occupies a critical role as a self-propelled anti-aircraft gun missile system, with up to 80 units already in Indian Army service prior to this contract. It is specifically designed to protect armored formations and maneuver units against close-range aerial threats that penetrate outer air defense layers. Its hybrid design integrates missile and gun systems on a single tracked platform, ensuring continuous engagement capability across very short to short ranges.

The missile component of Tunguska consists of the 9M311 series surface-to-air missiles, NATO designation SA-19 Grison. These are two-stage missiles featuring a solid-propellant booster for rapid acceleration and a sustainer stage carrying a fragmentation warhead. The missile uses radio-command guidance, with the system’s tracking radar and electro-optical sensors continuously guiding it to the target. This guidance method enhances resistance to electronic countermeasures and allows precise engagement of maneuvering targets.

The 9M311 missile has an effective engagement range of approximately 2.5–8–10 km and can intercept targets at altitudes up to around 3.5 km. It is optimized to defeat low-flying aircraft, attack helicopters, cruise missiles, and increasingly unmanned aerial systems, including small drones and loitering munitions. Its proximity fuze and fragmentation warhead increase lethality against small and agile aerial targets, which are typically difficult to intercept.

Complementing the missile system are twin 2A38M 30 mm automatic cannons with a combined rate of fire of up to 5,000 rds/min. These guns are effective at ranges of up to 4 km and provide a last line of defense when targets penetrate within the missile engagement envelope. The ability to rapidly switch between missile and gun engagements allows Tunguska to maintain continuous defensive coverage without engagement gaps.

The system is equipped with a 360° search radar and a dedicated tracking radar, enabling autonomous detection and engagement of targets. An electro-optical sight enables passive operation in high-electronic-warfare environments, reducing vulnerability to jamming. Mounted on a tracked GM-352 chassis, Tunguska offers high mobility and can operate alongside tanks and infantry fighting vehicles, ensuring protection during both offensive maneuvers and defensive operations.

Operationally, Tunguska fills a critical gap between man-portable air defense systems and larger platforms such as Akash. While medium-range systems provide area coverage, they are less effective against sudden, low-altitude threats emerging close to frontline units. Tunguska addresses this vulnerability by delivering immediate, high-density firepower capable of countering saturation attacks, including drone swarms and precision-guided munitions.

The procurement reflects India’s growing focus on countering emerging aerial threats, particularly along contested borders where drones and low-observable weapons are increasingly prevalent. Strengthening the close-in air defense layer enhances the survivability of combat units and complicates adversary targeting strategies.

From a strategic perspective, the deal underscores India’s continued reliance on Russian-origin systems for critical battlefield capabilities while maintaining a broader diversification strategy. By expanding its Tunguska fleet equipped with 9M311 missiles, the Indian Army reinforces its layered air defense doctrine, ensuring that each tier from long-range interception to point defense remains effective against the full spectrum of modern aerial threats.
