In a major strategic move that underscores India’s long-term defence priorities, New Delhi is in advanced negotiations with Moscow to procure five additional S‑400 Triumf surface-to-air missile systems. The deal is expected to be finalized before Russian President Vladimir Putin’s visit to India in December 2025, marking a significant deepening of India–Russia defence cooperation amid evolving regional security dynamics and growing threats to Indian airspace.
Building on Operational Success and Strategic Necessity
The programme to acquire additional S-400 systems is being accelerated after the weapons system demonstrated unprecedented effectiveness during Operation Sindoor in May 2025. Pakistan’s components of the Pakistan Air Force refrained from conducting extended air operations after S-400 systems at Adampur, Bhuj and other bases successfully intercepted multiple aerial targets, including an ELINT aircraft that was shot down at a range of over 314 km. The system also neutralized fighters such as F-16s and JF-17s during the operation, forcing enemy aircraft to linger beyond 300 km from the border.
This real-world performance validated India’s earlier decision to sign a $5.43 billion agreement with Moscow in 2018 for five S-400 units. Despite the United States’ sanction threats under Countering America's Adversaries Through Sanctions Act (CAATSA), New Delhi pressed ahead, and now considers additional acquisition essential to plug critical air-defence gaps, particularly along the 7,000 km coastline and northern borders.
Negotiations Focus: Production, Cost, and Deployment
According to defence officials, top-ranking representatives from India’s Ministry of Defence and their Russian counterparts are expected to conclude the new deal weeks before Putin’s December visit. Talks are centered on a hybrid acquisition model in which three of the five systems will be purchased directly from Russia, while the remaining two will be manufactured in India by private defence firms under a technology-transfer agreement.
These arrangements are meant to align with India’s goals of building defence-industrial autonomy and creating a robust maintenance, repair and overhaul (MRO) ecosystem. The cost framework reportedly includes annual escalations based on the 2018 baseline price.
It is noteworthy that rumours of S‑500 Prometey procurement are unfounded, as the system remains in development in Russia. However, the talks on potential future collaboration could evolve once the technology matures.
Complementary Enhancements: Su-30 MKI and Advanced Missiles
Parallel to air-defence bolstering, India is exploring upgrades for its mainstay fighter fleet, the Sukhoi Su‑30MKI. Officials are considering integration of the RVV‑BD missile — with a range exceeding 200 km — as a counter to Pakistan’s deployment of the Chinese PL-15. As part of the Super Sukhoi upgrade programme, the Su-30MKI will be fitted with advanced avionics, AESA radars, digital mission systems and increased indigenous content. These aircraft are expected to remain frontline assets well into the 2050s, thanks to phased upgrades.
Industrialisation and Indigenous Defence Drive
India’s push for additional S-400 units coincides with a broader push towards self-reliance in aerospace and defence technology. As part of its “Make in India” vision, New Delhi is considering launching joint-venture manufacturing lines for long-range air-defence systems, radar installations, and missile subsystems.
Indigenous projects like Project Kusha, an extended-range surface-to-air missile system in development by the Defence Research and Development Organisation (DRDO), are expected to complement foreign systems and reduce long-term dependency on imports. Officials expect Kusha to become operational by 2030, forming part of a layered multi-domain missile defence shield.
Strategic and Geopolitical Implications
The move also carries significant geopolitical implications. It reaffirms India’s long-standing defence partnership with Russia — a relationship accounting for more than 36% of its arms imports between 2020 and 2024. New Delhi has repeatedly refused to cede ground to Western pressure, maintaining defence trade ties while competing for global strategic influence.
The planned procurement may attract renewed scrutiny from Washington, which has previously imposed sanctions over India’s defence dealings with Russia. Nonetheless, Indian officials contend that national security imperatives outweigh external pressures.
The MGMM Outlook
India’s decision to procure five additional S-400 Triumf air defence systems from Russia reaffirms its commitment to national security and strategic independence. The move comes after the system’s extraordinary success in Operation Sindoor earlier this year, where it effectively deterred Pakistani air intrusions and neutralized multiple enemy targets. By reinforcing air defence coverage along both coastal and northern borders, New Delhi is taking a decisive step to ensure that no external power—whether through threat or pressure—can dictate its security policies. This procurement aligns with India’s enduring vision of self-reliance, balancing technological collaboration with Moscow while advancing indigenous production under the “Make in India” initiative.
In our view, this expansion of India’s aerial shield is more than a defence transaction—it’s a declaration of autonomy and preparedness in an increasingly uncertain world. With upgrades to the Su-30MKI fleet, integration of long-range missile technologies, and development of DRDO’s Project Kusha, India is steadily building a multi-layered air defence ecosystem that will protect its skies well into the future. Despite external scrutiny, especially from the West, India’s priorities remain clear: safeguarding sovereignty, deterring threats, and ensuring peace through strength.
