NEW DELHI, DECEMBER 2025 – To ensure a robust multi-layered air defense shield, the Government of India is in advanced negotiations with Russia for a major missile procurement deal valued at approximately ₹10,000 crore.
This strategic acquisition aims to significantly replenish and expand the missile inventory for the S-400 ‘Sudarshan’ Triumf air defense systems currently operational with the Indian Air Force (IAF).
Key Strategic Developments:
Operational Success: The procurement follows the highly successful performance of the S-400 system during the May 2025 conflict (Operation Sindoor), where it reportedly neutralized multiple high-value aerial threats at ranges exceeding 300 km.
Stockpile Replenishment: The deal focuses on the acquisition of 300 interceptor missiles, including very long-range (400 km) and medium-range variants, to replace stocks used during recent operations and build a decisive reserve.
Logistics & Maintenance: Alongside the missile purchase, India and Russia are establishing a dedicated Maintenance, Repair, and Overhaul (MRO) facility in India to ensure the long-term sustainability of the S-400 squadrons.
Future Readiness: While three S-400 squadrons are already operational, the remaining two from the 2018 contract are expected to be delivered by August 2026. Discussions are also exploring the potential induction of the next-generation S-500 Prometheus system.
Strategic Significance:
The ‘Sudarshan’ system remains the cornerstone of India’s Anti-Access/Area Denial (A2/AD) strategy. By fortifying its missile reserves, India reinforces its strategic autonomy and maintains a qualitative edge in regional air superiority, despite shifting global geopolitical dynamics.
