Russia Offers India 100 Locally Built Su-57 Stealth Fighters as New Delhi Faces Growing J-20 Threat and Fighter Squadron Crisis

(DEFENCE SECURITY ASIA) — Russia has reopened the most ambitious military aviation proposal offered to India in more than a decade, proposing joint production of at least 100 Su-57 stealth fighters inside India with extensive technology transfer.

The offer arrives when the Indian Air Force faces its deepest combat aviation deficit in decades, operating roughly 30 fighter squadrons despite an officially sanctioned requirement for 42 squadrons.

Moscow is therefore attempting to transform India’s immediate operational anxiety into a strategic industrial partnership, positioning the Su-57 as both a combat aircraft and manufacturing ecosystem.

Russian officials have proposed building the aircraft at Hindustan Aeronautics Limited’s Nashik facility, where the Su-30MKI has been manufactured for years under licence.

HAL Chairman and Managing Director D.K. Sunil confirmed that Russian technical teams have already assessed Nashik’s infrastructure and concluded nearly half the existing facilities remain reusable.

According to D.K. Sunil, the Russians believe approximately 50 percent of Nashik’s infrastructure could support Su-57 production after targeted upgrades, while additional investment would complete the remaining industrial transformation.

The proposal nevertheless exceeds current Indian Air Force preferences, because the service wants a quicker government-to-government acquisition of between 40 and 60 aircraft rather than committing immediately.

That smaller requirement reflects New Delhi’s desire to obtain an interim stealth capability rapidly while avoiding major disruption to indigenous programmes already consuming enormous financial and industrial resources.

India therefore faces a strategic dilemma between accepting Russia’s unprecedented transfer-of-technology package or protecting long-term indigenous ambitions centred upon Tejas, MRFA and the Advanced Medium Combat Aircraft.

The eventual decision could determine whether India’s next-generation fighter strategy remains primarily foreign-assisted, or becomes increasingly dominated by domestic industrial sovereignty and future sixth-generation collaboration.

If Moscow delivers an acceptable quotation, India could suddenly find itself choosing between the world’s largest foreign stealth-fighter localisation programme and its own delayed but politically vital AMCA roadmap.

The stakes therefore extend beyond fighter procurement alone, because whichever option New Delhi selects will shape India’s aerospace-industrial base, regional deterrence posture and long-term strategic autonomy.

Why Russia Wants a 100-Aircraft Production Programme

Russia is insisting upon a minimum order approaching 100 aircraft because anything smaller would struggle economically to justify building a completely new stealth fighter production infrastructure.

Russian planners view a large production run as essential because the industrial investment required for tooling, specialised coatings, avionics integration and engine support would otherwise become financially inefficient.

Moscow has therefore proposed converting HAL’s Nashik complex into a dedicated Su-57 manufacturing hub, potentially replicating the earlier Su-30MKI model on a stealth platform.

The Nashik facility already possesses decades of experience handling Russian-origin fighter designs, logistics systems, technical documentation and licensed manufacturing procedures under highly localised conditions.

Russian teams reportedly concluded that nearly 50 percent of Nashik’s infrastructure can be repurposed directly, significantly reducing the initial cost and construction timeline.

The remaining industrial transformation would require fresh investment into stealth-compatible assembly lines, composite material handling facilities, secure software laboratories and specialised radar-absorbent coating workshops.

Russia has also indicated willingness to permit increasing Indian content over time, beginning with semi-knocked-down kits before eventually expanding domestic manufacturing and subsystem integration.

That localisation pathway mirrors the earlier Su-30MKI experience, where imported Russian components gradually gave way to higher indigenous participation across structures, electronics and maintenance systems.

Why the Indian Air Force Remains Deeply Cautious

Despite the attraction of a near-term stealth capability, the Indian Air Force remains reluctant to commit immediately to Moscow’s far larger industrial proposal.

The service currently favours purchasing between 40 and 60 aircraft directly from Russia because such a government-to-government arrangement would accelerate operational induction.

Indian planners believe a smaller acquisition could provide an immediate counterweight against regional fifth-generation threats while avoiding the financial burden accompanying full-scale local production.

The Indian Air Force is simultaneously financing 180 Tejas Mk1A fighters, roughly 120 Tejas Mk2 aircraft and the long-delayed Multi-Role Fighter Aircraft competition.

That MRFA programme could eventually produce another 114 fighters, potentially including Rafale F4, Rafale F5 or competing Western platforms with advanced sensor integration.

Beyond those commitments, New Delhi still considers the indigenous Advanced Medium Combat Aircraft programme its most important long-term aerospace project.

The AMCA programme is expected eventually to generate more than 120 Indian-designed fifth-generation fighters entering service during the 2030s, creating anxiety about overlapping expenditures.

Indian officials therefore fear that committing billions of dollars to a locally manufactured Su-57 fleet could undermine political momentum and industrial concentration behind AMCA.

Technology Transfer Could Become the Decisive Variable

Russia is attempting to overcome Indian hesitation by presenting what officials describe as an unprecedented transfer-of-technology package unavailable through most Western competitors.

The proposal reportedly includes access to source codes, local integration rights and the possibility of incorporating Indian-designed systems into future Su-57 production.

Moscow has specifically indicated that indigenous Indian weapons such as the Astra beyond-visual-range missile could eventually be integrated onto locally manufactured aircraft.

Russian negotiators have also suggested that future Indian-built Su-57 variants might incorporate indigenous radars, mission computers and electronic warfare equipment.

Such flexibility would address one of India’s longstanding complaints regarding imported fighters, where restrictive foreign intellectual property frequently limits domestic upgrades and modifications.

The renewed Russian offer therefore differs significantly from the earlier Fifth Generation Fighter Aircraft project abandoned by India during 2018.

New Delhi withdrew from that original FGFA arrangement largely because of escalating costs, insufficient technology access and continuing doubts regarding the Su-57’s overall maturity.

Russia is now attempting to reverse those perceptions by emphasising deeper localisation, broader technology sharing and substantially greater Indian control over the final platform.

The Shadow of the Abandoned FGFA Programme

The current negotiations cannot be separated from the legacy of the earlier FGFA project, which remains deeply influential within Indian defence circles.

That previous programme envisioned India and Russia jointly developing a customised derivative of the Su-57, yet disagreements ultimately overwhelmed the partnership.

Indian officials repeatedly complained during the earlier negotiations that Russia remained unwilling to share critical design information, stealth technologies and engine development knowledge.

Those tensions eventually produced India’s withdrawal during 2018, creating a perception inside New Delhi that Russian promises regarding technology transfer required careful verification.

Moscow nevertheless appears determined to revive selected FGFA concepts within the new proposal, albeit under significantly different industrial and operational conditions.

Russian officials have floated a possible twin-seat Su-57E variant specifically configured for commanding unmanned combat drones and distributed battlefield networks.

That concept reflects broader international interest in future crewed-uncrewed teaming, where advanced stealth fighters coordinate large numbers of autonomous supporting aircraft.

Indian enthusiasm for that specific configuration nevertheless appears limited, largely because New Delhi remains focused upon solving immediate squadron shortages rather than experimental operational concepts.

China, Regional Threats and the Strategic Calculation

India’s interest in the Su-57 ultimately reflects growing concern regarding the expanding Chinese inventory of advanced combat aircraft across the Indo-Pacific theatre.

China already operates the J-20 stealth fighter in increasing numbers and is simultaneously expected to introduce the carrier-capable J-35 during coming years.

Indian strategists therefore increasingly fear that the regional balance of airpower could shift decisively unless the Indian Air Force acquires an interim fifth-generation capability.

The Su-57 consequently appears attractive because it could potentially enter Indian service years before the indigenous AMCA becomes operational.

A fleet of 40 to 60 Su-57 fighters could therefore provide a bridging capability while preserving enough resources for eventual AMCA production.

A larger programme involving more than 100 locally produced aircraft would, however, create a dramatically different strategic and financial equation for New Delhi.

Such an arrangement could provide India with long-term stealth manufacturing expertise while simultaneously deepening dependence upon Russian technology, supply chains and industrial support.

No agreement has yet been signed, leaving HAL, the Indian Air Force and the Indian government still awaiting detailed Russian cost estimates, production timelines and investment requirements.

Any delay in those commercial details risks strengthening arguments within India that resources should instead remain concentrated upon accelerating Tejas Mk2 and AMCA development.

Russian negotiators nevertheless appear convinced that India’s worsening squadron shortage and China’s expanding stealth inventory will eventually force New Delhi towards a compromise solution.

If India ultimately accepts even a limited Su-57 acquisition, the aircraft could become the Indian Air Force’s first operational stealth platform and fundamentally alter regional airpower calculations.

Conversely, rejection of the proposal would signal that New Delhi is prepared to tolerate a prolonged near-term capability gap in exchange for preserving complete indigenous control over its future combat aviation architecture.
