India Weighs Russia’s S-500 and Su-57 Offers as It Builds Its Own Shield and Stealth Fleet

Russia is offering India two of its most advanced systems: the S-500 Prometheus air-and-missile defence network and the Su-57 Felon fifth-generation fighter. The pitch followed Prime Minister Narendra Modi’s meeting with President Vladimir Putin in Bishkek on 31 August and comes ahead of another meeting in New Delhi around the BRICS summit. India is strengthening air defence and combat aviation while expanding domestic programmes such as Project Kusha and the Advanced Medium Combat Aircraft. Moscow wants a larger share of that modernisation. New Delhi is assessing the offers against systems it already operates, systems it is developing, and the need for timely, reliable capability.
The Russian proposals sit alongside a live expansion of the S-400 fleet, not in place of it. Russia has submitted a detailed bid for five more S-400 squadrons after an Indian tender. The project is estimated at more than ₹50,000 crore. The Defence Acquisition Council cleared the extra five in March 2026, after Operation Sindoor. Under the 2018 contract India ordered five squadrons. Four are in service. The fifth is expected by November 2026. A new contract would add depth on both fronts. Reports say two of the extra units could be produced in India with technology transfer and private-sector participation, with three sourced from Russia. India is also replenishing interceptor stocks with more than 280 additional missiles for current and future batteries.
S-400 in service, S-500 under study
The S-400 earned stronger confidence during Operation Sindoor in May 2025, when Indian batteries engaged Pakistani drones, missiles and aircraft. One long-range engagement against an airborne early warning aircraft was widely reported. Extra squadrons would extend that coverage on the western and eastern fronts and sit inside a layered Indian air-defence architecture.
The S-500 is presented by Russia as the next rung above the S-400, with claimed reach against ballistic missiles, high-altitude targets and, in some accounts, low-orbit satellites, and a faster reaction time than the earlier system. India has been mentioned as a possible first export customer since 2021. New Delhi already has a parallel track. Project Kusha is an indigenous long-range system in the S-400 class, and ballistic missile defence work is well advanced. Any S-500 decision will turn on whether it adds a distinct layer, arrives on a usable schedule, and integrates with Indian sensors and command networks. That is a capability test, not a shortage of options.
Fighters: AMCA on the long runway, Su-57 on the table
The Su-57 conversation has a longer history. India left the joint Fifth Generation Fighter Aircraft programme with Russia in 2018 and put its weight behind AMCA. In June 2026 Putin said Russia had completed the jet independently and was ready to supply it and develop it further with India, including, in some reports, deeper access than a standard export model. HAL’s existing Su-30MKI industrial base at Nashik, Koraput and related sites has been cited as a foundation if co-production were ever chosen.
India’s fighter modernisation is running on several tracks at once: Tejas induction, Su-30MKI upgrades with HAL, additional Rafales, and AMCA. The first AMCA prototype is expected late this decade, with service entry targeted for the next decade. China fields J-20s in growing numbers and Pakistan is expected to receive the J-35. That regional picture is why a limited Su-57 batch has been discussed in some quarters as an interim option. Defence Secretary Rajesh Kumar Singh has said India is not planning a new Sukhoi variant in the near term, language widely read as keeping the focus on AMCA and existing fleet upgrades. Other reports still describe a small off-the-shelf lot as under examination. Adding a new type would have to justify itself against training, maintenance and weapons integration. India already operates a mixed but capable fleet of Su-30MKI, MiG-29, Rafale, Mirage 2000, Jaguar and Tejas. The choice is how best to add stealth while protecting the indigenous programme.
A wider partnership, and a wider market
Russia’s briefcase also includes the Voronezh early-warning radar, a deep upgrade of the Su-30MKI fleet with HAL, and work on Russian-origin Kilo-class submarines. Kremlin spokesman Dmitry Peskov has publicly backed talks on the Su-57. Putin’s coming visit for BRICS gives both sides another chance to compare notes.
India has spent years widening its supplier base across the United States, France, Israel and its own industry, while Russian-origin platforms remain a large and familiar part of the inventory. That mix gives New Delhi leverage. Maintenance and upgrades of systems already in service will continue. New buys will be judged on transfer of technology, delivery certainty, and how they support Make in India.
The MGMM Outlook
India’s evaluation of Russia’s S-500 air defence system and Su-57 stealth fighter reflects a broader strategy of strengthening national security while preserving long-term self-reliance. As New Delhi expands its defence capabilities through additional S-400 squadrons, indigenous Project Kusha, and the Advanced Medium Combat Aircraft (AMCA), every major acquisition is being measured against operational value, technology transfer, and its ability to integrate with India’s evolving military architecture rather than immediate geopolitical considerations.
The discussions with Russia also highlight India’s balanced approach to defence modernisation. While Russian platforms continue to play an important role in the armed forces, India is simultaneously investing in domestic manufacturing, advanced research, and partnerships that support the Make in India vision. The focus remains on building a layered air defence network and a future-ready stealth fleet through carefully selected capabilities that strengthen India’s strategic autonomy and long-term security interests.
