The Indian Army's long-delayed acquisition of a Self-Propelled Air Defence Gun Missile System (SPAD-GMS) has received fresh momentum.
Following years of procedural delays and a brief pivot toward entirely local designs under the Atmanirbhar Bharat framework, the multi-billion-dollar acquisition programme has been revived.
South Korea's Hanwha Aerospace has capitalised on this restart by positioning its upgraded K-30 SAM Biho and the next-generation Biho-II platforms as the primary contenders for the contract.
Evolution of the Biho System
The base K-30 Biho platform is currently operational within the Republic of Korea Army.It features dual 30mm automatic cannons, advanced electro-optical fire control networks, and integrated short-range surface-to-air missiles designed to neutralize low-altitude threats such as helicopters and unmanned aerial vehicles (UAVs).
The upgraded Biho-II variant incorporates several modern battlefield refinements.
The newer model introduces upgraded target acquisition sensors, advanced combat networking, superior cross-country mobility, and enhanced counter-drone capabilities.
Hanwha has adjusted the vehicle’s design across several global defense exhibitions to deliver an optimized configuration that balances firepower, armored protection, and rapid deployment alongside fast-moving mechanized formations.
Technical Trials and Competitive Edge
During earlier field evaluations conducted by the Indian Ministry of Defence, the South Korean platform reportedly outclassed its prominent Russian rivals, including the Pantsir-S1 and the Tunguska-M1.Independent assessments highlighted that the Biho system delivered superior accuracy against low-flying aerial targets, higher mechanical reliability, competitive pricing, and more dependable delivery schedules.
Furthermore, the Russian bids faced complications regarding offset obligations and projected lifecycle maintenance costs, which ultimately gave Hanwha Aerospace a decisive advantage in early technical rounds.
The L&T Partnership and Local Manufacturing
To comply with New Delhi's stringent technology transfer requirements, Hanwha plans to mirror its existing production strategy used for the K9 Vajra-T 155mm tracked artillery gun.For that project, Hanwha partnered with Indian engineering giant Larsen & Toubro (L&T) to assemble the howitzers locally at L&T’s armored systems complex in Hazira, Gujarat.
The K9 program successfully achieved over 50% to 80% indigenisation, establishing a proven blueprint that Hanwha intends to use for the SPAD-GMS program to secure high domestic content from the first production run.
Strategic Necessity and Program Value
The procurement is expected to cover approximately 104 tracked air defence systems, with an estimated contract value between $2.5 billion and $2.6 billion.The tender framework stipulates that local industrial participation must progressively scale up to 80% as production advances.
The requirement comes at a crucial time for the Indian Army.
Escalating drone activities, loitering munitions, and low-altitude aerial incursions along forward border regions have made mobile, tracked air defence shields a critical priority.
Armored mechanized columns require continuous, all-weather protection while on the move.
The Biho-II’s hybrid gun-and-missile architecture addresses this vulnerability by offering rapid-fire point defence alongside guided missile interception to counter modern, distributed saturation threats.
Indigenous Alternatives and Parallel Tracks
While the Biho-II holds a strong position due to its mature design and previous trial successes, the program operates alongside parallel domestic developments.The Defence Research and Development Organisation (DRDO) has proposed a native Self-Propelled Air Defence Gun Missile System (ADGM-SP) built upon the chassis of the newly developed Zorawar Light Tank.
The DRDO's proposed hybrid platform aims to combine twin 30mm guns with indigenous Very Short-Range Air Defence Systems (VSHORADS) to create a highly mobile system optimized for high-altitude deployment in sectors like Ladakh.
