Russian President Vladimir Putin has renewed Moscow’s push to sell and jointly produce the Su-57 stealth fighter with India, reviving long-standing discussions on fifth-generation combat aviation cooperation and explicitly linking the proposal to the earlier India–Russia Fifth Generation Fighter Aircraft (FGFA) program.
Speaking to global media on the sidelines of the St Petersburg International Economic Forum, Putin described the Su-57 as “fifth-generation technology” and asserted that it represents “the best in the world as of now,” while reaffirming Russia’s readiness to deepen defense-industrial cooperation with India.
“It’s fifth-generation technology — I think it’s the best in the world as of now,” the Russian president said, reiterating Moscow’s openness to export, joint production, and continued development of the platform in partnership with New Delhi.
The renewed pitch comes as global competition in stealth combat aviation intensifies, with four other operational fifth-generation fighters currently in service: the United States’ Lockheed Martin F-22 Raptor and Lockheed Martin F-35 Lightning II, and China’s Chengdu J-20 and Shenyang J-35A.
Putin explicitly referenced the earlier FGFA cooperation framework between Moscow and New Delhi, noting that both sides had once considered jointly developing a fifth-generation fighter but failed to complete the project.
“As far as the Su-57 goes, at one point we proposed to our Indian friends to work together on this technology,” Putin said. “But back then, our Indian friends said: ‘Go ahead on your own, and then we will see — maybe we’ll join’… The aircraft could have been our joint project. We built it independently, but we are ready to work with India in this field.”
The FGFA program, formally tied to the Russian PAK FA initiative, was originally intended to be a co-developed stealth fighter based on Sukhoi’s experimental platform that later became the Sukhoi Su-57. India’s participation was expected to include deep technology sharing, production workshare, and customization for Indian Air Force requirements.
India withdrew from the program in 2018 after years of disagreement over cost, performance expectations, stealth characteristics, and technology transfer conditions. At the time, Indian defense officials cited concerns over radar cross-section performance, engine maturity, and the lack of access to source code and critical design data.
Despite the withdrawal, both sides never formally closed the door on future cooperation.
Russia’s latest proposal builds on a series of evolving offers made to India over the past year. At the Aero India Show in February 2025, Moscow reportedly presented the Su-57E export variant alongside a broad industrial cooperation package that included off-the-shelf aircraft deliveries, licensed production in India, and support for India’s indigenous fifth-generation program, the HAL Advanced Medium Combat Aircraft (AMCA).
Subsequent discussions, involving Russia’s state arms exporter Rosoboronexport, expanded the proposal further to include leveraging India’s existing Su-30MKI manufacturing ecosystem to support local assembly of the Su-57E.
By November 2025, Russian officials reportedly upgraded the offer again, adding full licensed production rights, deeper technology transfer provisions, and the introduction of a twin-seat variant, now undergoing testing in Russia. Some Indian media reports have further suggested — though not independently verified — that discussions may even include access to certain software architecture or source-level integration if joint production proceeds.
These claims have not been confirmed by Russian or Indian authorities.
Beyond the aircraft itself, Putin used his remarks to emphasize Russia’s continued defense partnership with India and to defend New Delhi’s strategic autonomy.
He described India as a “great country” and suggested that external pressure on its defense and energy cooperation with Russia is counterproductive.
“We don’t have any issues with it or any limitations. The same goes for air defense systems,” Putin said, underscoring Moscow’s willingness to expand cooperation beyond combat aviation into broader military systems.
The comments appeared to indirectly reference ongoing Western scrutiny of India’s continued defense ties with Russia, particularly in the context of sanctions regimes and geopolitical tensions following the Ukraine conflict.
India’s defense relationship with Russia has periodically drawn criticism from Washington. The United States has previously warned that major arms purchases from Moscow could trigger sanctions under the Countering America’s Adversaries Through Sanctions Act (CAATSA).
Earlier this year, US officials reiterated concerns about Russian arms deals at a Senate Foreign Relations Committee hearing, describing such transactions as “very concerning” and potentially sanctionable depending on scale and strategic impact.
At the same time, trade tensions between Washington and New Delhi have fluctuated. The United States imposed tariffs on certain Indian imports last year over disagreements linked to Russian oil purchases, though these measures were partially eased earlier this year amid broader negotiations on a trade framework that has yet to be finalized.
Interestingly, Putin’s renewed Su-57 outreach came in a week where US President Donald Trump also made conciliatory remarks toward India, calling Prime Minister Narendra Modi his “good friend” and expressing optimism about reaching a bilateral agreement.
“We will get to a deal because I like your prime minister a lot… He is a good friend of mine,” Trump said, signaling continued engagement despite unresolved trade differences.
Analysts note that the simultaneous messaging from Moscow and Washington highlights India’s increasingly central position in great-power competition, particularly in defense procurement and strategic alignment.
For India, the Su-57 proposal arrives at a critical juncture in its airpower modernization strategy. The Indian Air Force continues to face a widening capability gap as regional adversaries expand their stealth and next-generation fleets.
China currently operates both the Chengdu J-20 and the Shenyang J-35A, while also advancing early sixth-generation prototypes such as the Chengdu J-36 and Shenyang J-50. Pakistan, meanwhile, is reportedly preparing to acquire approximately 40 J-35A aircraft, further altering regional airpower balances.
India’s indigenous AMCA program is not expected to enter operational service until the mid-2030s, leaving a long capability gap in the interim.
This gap has intensified internal debate within India’s defense establishment over whether to pursue an interim fifth-generation platform.
Earlier statements from senior Indian Air Force leadership suggested that an off-the-shelf fifth-generation acquisition remains under consideration, depending on availability, cost, and strategic alignment.
Russia has sought to address earlier criticisms of the Su-57 by introducing incremental upgrades to its design and propulsion systems. A key development is the maturation of the Izdeliye 30 engine family, also known as AL-51F-1, designed to improve thrust, efficiency, and reliability while enabling sustained supercruise capability.
Structural and material improvements have also been introduced, including expanded use of radar-absorbent materials, refined panel alignment, and changes to airframe fasteners to reduce radar signature. Engine nozzle modifications aimed at reducing infrared and radar detectability have also been incorporated.
These enhancements are intended to bring the aircraft closer to Western fifth-generation benchmarks, particularly in low observability and propulsion performance — areas that were previously cited as concerns during India’s withdrawal from the FGFA program.
Despite the renewed push, analysts caution that India’s decision calculus remains complex. Accepting the Su-57 could strengthen short-term capabilities but may risk diplomatic friction with the United States and potential exposure to sanctions pressure.
At the same time, rejecting the offer could deepen reliance on older fourth-generation fleets and widen the capability gap as China accelerates both fifth- and sixth-generation development programs.
India’s parallel engagement in European sixth-generation initiatives — including the Global Combat Air Programme (GCAP) and the Future Combat Air System (FCAS) — adds further complexity, as both programs face delays and internal disagreements that could limit near-term viability.
For Moscow, the Su-57 pitch represents both a commercial opportunity and a strategic effort to maintain India as a key defense partner amid shifting global alignments.
For New Delhi, it revives an unresolved question that has persisted for nearly two decades: whether deeper integration with Russian aerospace technology offers a viable bridge to next-generation airpower, or whether strategic and technological constraints outweigh the benefits.
As geopolitical competition intensifies and fifth-generation fleets become increasingly central to air superiority, the Su-57 proposal ensures that India’s fighter modernization debate remains firmly at the center of global defense diplomacy.
