India faces a critical decision: Russia’s offer of Su-57 stealth fighters and S-500 air defence systems could plug immediate capability gaps, but the deal’s value depends on full technology transfer, source-code access, and co-production to avoid long-term dependence. Major Gaurav Arya stresses that India has only a limited strategic window to negotiate such terms in an interview with Times of India.

Russia has placed the Su-57 and S-500 at the centre of its defence pitch to India. The Su-57 is a fifth-generation stealth fighter combining low observability, advanced avionics, long-range weapons, and supermanoeuvrability.

India’s Air Force currently suffers from depleted squadron strength, with only 29 operational squadrons against a sanctioned strength of 42. The indigenous Advanced Medium Combat Aircraft (AMCA) program is unlikely to see its first flight before 2029–30, leaving a dangerous stealth gap as China expands its J-20 fleet and Pakistan prepares to induct J-35 fighters.

Major Arya argues that India should not restrict itself to a token Su-57 purchase. Instead, a larger order could provide meaningful deterrence while strengthening India’s bargaining position for deeper industrial cooperation. He emphasises that India must demand complete transfer of technology, access to source code, and localisation rights. Without these, India risks repeating past mistakes of importing platforms without mastering their ecosystems.

The S-500 Prometheus represents Russia’s most advanced long-range air and missile defence system. With an interception range of around 600 km and capability against ballistic missiles, hypersonic threats, and near-space targets, it would add a higher-tier shield above India’s existing S-400 batteries. 

Russia has reportedly offered co-production of the S-500 in India, which could transform the acquisition into an industrial partnership with local manufacture, sustainment, and even third-country exports.

India’s operational experience with the S-400 during Operation Sindoor, where it successfully countered Pakistani aerial threats, has already validated Russian air defence technology.

However, Arya cautions that India must avoid overlapping with indigenous programs such as Project Kusha, which aims to deliver a homegrown long-range air defence capability. The decision must weigh whether the S-500 fills a genuine capability gap or risks duplication.

Russia has also proposed an $11 billion upgrade of India’s Su-30MKI fleet into “Super Sukhois”, with AESA radars, modern avionics, electronic warfare systems, and new engines. This would complement any Su-57 acquisition but also add to India’s already diverse fighter inventory, which includes Su-30MKI, MiG-29, Rafale, Mirage-2000, Jaguar, and TEJAS. Each type brings its own logistical burden.

The strategic pressure is undeniable. China’s expanding stealth fleet and missile arsenal, combined with Pakistan’s expected J-35 induction, compress India’s timelines. Arya insists that India cannot afford to wait passively for AMCA. A negotiated Su-57 and S-500 package, with ironclad guarantees of technology transfer and industrial participation, could bridge the gap while strengthening indigenous capability.

Yet the risks are substantial. Importing another Russian fighter type enlarges training, maintenance, and supply-chain complexity. The S-500’s integration into India’s existing command architecture, sensors, and indigenous systems remains uncertain. Financial costs, delivery schedules, and long-term dependence on Russian logistics are unresolved.

The limited strategic window lies in the current geopolitical context. With Russia seeking to offset Western sanctions and India diversifying suppliers, Moscow is more likely than ever to concede deeper cooperation. Arya concludes that India must seize this moment to negotiate hard, ensuring that any Su-57 or S-500 deal is not just about buying platforms but about building sovereign capability.
