Russia is stepping up efforts to secure India as a potential partner for its export-configured Su-57E fifth-generation stealth fighter, reportedly offering a comprehensive package that extends beyond aircraft procurement to include domestic manufacturing, technology transfer and long-term industrial cooperation. The proposals discussed have included different acquisition options, ranging from small batches of fully assembled aircraft to potential purchases exceeding 100 fighters.
A key element of the reported offer is the local assembly and manufacture of approximately 100 Su-57E aircraft in India. Russia has reportedly proposed using Hindustan Aeronautics Limited’s (HAL) Nashik facility, which has extensive experience in the licensed production, assembly and support of the Su-30MKI fleet.
The proposal seeks to leverage India’s established aerospace infrastructure, domestic supply chains and technical expertise developed through decades of cooperation with Russia on combat aircraft. Reusing these capabilities could help streamline the transition to a new production programme and potentially reduce the time and investment required to establish manufacturing operations.
Another significant feature of the reported package is the proposed transfer of advanced technologies, including access to source code associated with onboard systems and mission software. Such access could give India greater control over aircraft maintenance, software upgrades and modifications to mission systems, while reducing reliance on the original manufacturer for certain future capability enhancements. However, the precise scope and terms of any proposed technology transfer have not been publicly established.
The offer reportedly includes provisions for integrating Indian-developed weapons and subsystems into the aircraft. These could include the Astra beyond-visual-range air-to-air missile family, Rudram anti-radiation missiles and other indigenous precision-guided munitions. The proposed integration would potentially enable the Indian Air Force to adapt the fighter to its operational requirements and expand the use of domestically developed weapons.
Russia has also reportedly discussed incorporating Indian sensors and future Gallium Nitride-based Active Electronically Scanned Array (AESA) radars. If technically and contractually agreed, these modifications could provide greater scope for customising the aircraft’s avionics, radar and mission systems to suit India’s requirements.
Alongside the domestic manufacturing proposal, Moscow has presented options for delivering smaller batches of fully assembled Su-57E fighters directly from Russian production lines. The reported options range from an initial delivery of eight aircraft to potential flyaway purchases of approximately 20–40 fighters.
Such deliveries could provide the Indian Air Force with access to fifth-generation combat aircraft while India’s indigenous fighter development programme continues. However, the operational value of this approach would depend on delivery schedules, acquisition costs, maintenance arrangements, weapons integration and the availability of supporting infrastructure.
The discussions are taking place amid intensifying regional competition in advanced combat aviation. China continues to expand its fifth-generation fighter capabilities, while developments in stealth technology, electronic warfare, sensor fusion and network-centric operations are influencing airpower modernisation across the region.
Despite the scope of Russia’s reported offer, India has not publicly committed to a large-scale Su-57E acquisition. New Delhi continues to balance immediate operational requirements with long-term objectives for domestic aerospace development, fleet modernisation and defence manufacturing.
One of India’s principal priorities is the Super Sukhoi programme, which aims to modernise the Su-30MKI fleet through upgrades to avionics, sensors, weapons and electronic warfare capabilities. The initiative is intended to extend the aircraft’s operational relevance and strengthen its combat effectiveness over the coming decades.
India is also pursuing additional Rafale fighters to reinforce frontline combat capabilities and address shortages in fighter squadron strength. These procurement efforts form part of a broader strategy to maintain operational readiness while indigenous combat aircraft programmes progress.
At the centre of India’s long-term aerospace ambitions is the Advanced Medium Combat Aircraft (AMCA) programme, which seeks to develop an indigenous fifth-generation stealth fighter. The project is considered an important component of India’s efforts to strengthen domestic design, engineering, manufacturing and advanced combat aviation capabilities.
The emphasis on AMCA development also shapes India’s approach to potential foreign fighter acquisitions. A major Su-57E procurement could involve substantial financial commitments, industrial capacity and technical resources, requiring careful consideration alongside the funding and development needs of the indigenous programme.
India’s earlier participation in the Fifth Generation Fighter Aircraft (FGFA) programme, which was based on the Russian Su-57 design, ended after disagreements and concerns involving costs, aircraft capabilities, development responsibilities and technology sharing. Russia’s reported renewed offer appears intended to address some of these earlier concerns through expanded localisation, industrial participation and deeper access to technology.
Overall, the reported Su-57E proposal presents India with several possible pathways to fifth-generation fighter capability, including direct imports, domestic manufacturing and extensive technology cooperation. India’s eventual approach will depend on the terms of the offer, operational requirements, financial considerations and the need to sustain progress on indigenous programmes such as the AMCA.
