India Explores Su-57E Local Production as Fighter Gap Widens
India Su-57E fighter talks have entered a deeper phase as New Delhi evaluates local production of Russia’s fifth-generation stealth aircraft to address growing capability gaps in the Indian Air Force. The discussions come as the United States quietly positions the F-35 as a potential long-term option, highlighting India’s widening set of strategic choices in fighter modernization.
According to reporting by Army Recognition and Indian defense officials, Moscow has proposed assembling the export variant Su-57E in India, potentially under a framework aligned with Make in India defense manufacturing goals. The proposal arrives amid delays in India’s indigenous Advanced Medium Combat Aircraft program and sustained pressure from regional airpower developments in China and Pakistan.
India’s Fifth-Generation Fighter Dilemma
Capability Gaps Drive Urgency
The Indian Air Force currently operates around 30 squadrons, well below the authorized strength of 42. Modernization efforts have been slowed by delays in indigenous programs and limited progress in foreign acquisitions beyond the Rafale fleet.
China’s operational deployment of the J-20 stealth fighter has sharpened concerns in New Delhi, particularly regarding air dominance and long-range strike capabilities. In this context, India’s interest in the Su-57E reflects a near-term attempt to secure fifth-generation capabilities without waiting for domestic development timelines to mature.
The Su-57E is Russia’s export-configured version of its stealth fighter, featuring reduced sensitive technologies compared to the domestic Su-57, but retaining low observability features, internal weapons bays, and advanced sensors.
What Russia Is Offering India
Local Assembly and Technology Access
Moscow’s proposal reportedly includes domestic assembly in India, with possible technology transfer linked to avionics integration, weapons compatibility, and maintenance infrastructure. Russian officials have emphasized flexibility on customization, including the integration of Indian or third-party systems.
India previously partnered with Russia on the Fifth Generation Fighter Aircraft program, a joint derivative of the Su-57, but withdrew in 2018 citing concerns over cost, stealth performance, and engine maturity. The renewed Su-57E discussions suggest both sides are revisiting the concept under revised terms.
For India, local production would support industrial capacity, reduce long-term sustainment risks, and align with strategic autonomy objectives. For Russia, India remains one of the few partners capable of sustaining high-end aerospace cooperation amid sanctions and export restrictions.
How the U.S. F-35 Fits Into the Picture
Strategic Option, Not a Near-Term Deal
While India Su-57E fighter talks are gaining momentum, U.S. officials have increasingly referenced the F-35 as a potential future option. Any F-35 pathway would involve strict interoperability, data security, and political alignment requirements that differ significantly from Russian platforms.
Washington views India as a key Indo-Pacific partner, but an F-35 sale would require long-term policy alignment, interoperability commitments, and potential constraints on India’s existing Russian-origin systems, including the S-400 air defense network.
Defense analysts note that while the F-35 offers proven stealth performance, sensor fusion, and networked warfare capabilities, it remains a strategic rather than immediate option for India due to cost, basing requirements, and political considerations.
Operational and Technical Considerations
Stealth, Engines, and Sustainment
The Su-57E’s current configuration continues to evolve, particularly in engine development and radar cross-section reduction. Russia is working to field the Izdeliye 30 engine, which is expected to improve thrust, fuel efficiency, and thermal management.
Indian planners are expected to closely evaluate sustainment models, mission readiness rates, and lifecycle costs, areas that have historically challenged Russian-origin platforms. Western aircraft typically offer stronger logistics transparency, but at higher acquisition and operational costs.
Any Indian Su-57E variant would also require integration with existing command, control, and sensor networks, including indigenous datalinks and airborne early warning platforms.
Strategic Signaling and Geopolitical Balance
Multi-Alignment in Practice
India’s parallel engagement with Russia and the United States reflects its long-standing multi-alignment strategy. Rather than committing exclusively to one supplier, New Delhi continues to assess competing offers to preserve leverage, operational flexibility, and strategic autonomy.
The Indian Air Force fifth generation fighter decision will carry long-term implications for training pipelines, weapons inventories, and alliance interoperability, particularly as India expands defense cooperation with the United States, France, and Japan.
What Comes Next
Decision Timeline Remains Unclear
No formal contract or request for proposal has been announced. Defense officials indicate that feasibility studies, cost assessments, and operational evaluations are ongoing. Any decision is likely to follow broader reviews of India’s combat aircraft roadmap, including the AMCA and additional Rafale acquisitions.
Observers expect incremental progress rather than a rapid commitment, with India weighing industrial benefits, geopolitical risk, and operational readiness before choosing a path forward.
