Russia Renews Su-57E Offer to India as Ambassador Alipov Signals Deep Technology Cooperation

Russia has renewed its pitch for the Su-57 fifth-generation fighter to India, with Russian Ambassador Denis Alipov signalling that Moscow is prepared to offer unusually deep defence-industrial and technology cooperation if New Delhi chooses to pursue the aircraft.

Speaking on September 4, Alipov said India already operates the world’s largest fleet of the Indian-modified Su-30 family and that cooperation around the platform continues, while Russia is also offering its newest fifth-generation Su-57 fighter.

Russian reporting quoting the ambassador said Moscow has “almost no secrets” from New Delhi when it comes to the development and production of weapons, underlining Russia’s effort to distinguish its proposal through technology access rather than presenting the Su-57 simply as an off-the-shelf fighter purchase.

The latest comments continue a sustained Russian campaign to position the Su-57E as a potential option for India’s future combat-aircraft requirements. At Aero India in February 2025, Russia displayed the Su-57E in India for the first time and publicly offered New Delhi the possibility of joining the programme through local production and technology sharing.

Alipov subsequently said Russia was offering not only to sell the fighter but also to co-produce it in India, share technologies, establish the necessary industrial facilities and accommodate configuration changes sought by India.

The proposal received another high-level endorsement this year. Speaking at the St Petersburg International Economic Forum on June 5, 2026, Russian President Vladimir Putin said Russia was fully prepared to supply the Su-57 to India. He recalled that Moscow had originally proposed developing the fifth-generation fighter jointly with India before the earlier programme failed to materialise.

Russia’s wider defence relationship with India provides the background to the offer. The two countries have progressively moved from straightforward buyer-seller arrangements toward licensed production, joint ventures and co-development. The Su-30MKI, BrahMos cruise missile, T-90 tanks and AK-203 rifle programme all involve varying degrees of Indian manufacture or bilateral industrial cooperation.

The December 2025 India-Russia summit joint statement also explicitly said the defence partnership was being reoriented towards joint research and development, co-development and co-production of advanced defence technologies and systems. The two sides additionally agreed to encourage greater manufacturing of Russian-origin defence components in India through technology transfer and joint ventures.

The Su-57 proposal therefore fits into a broader Russian argument: that Moscow can offer India not merely a fifth-generation aircraft but a pathway involving domestic manufacture, technology access and integration with India’s existing aerospace-industrial base.

India’s principal indigenous fifth-generation programme remains the Advanced Medium Combat Aircraft, or AMCA, while the country is simultaneously pursuing the Tejas Mk2 and a major modernisation of its Su-30MKI fleet.

For Moscow, the argument in favour of the Su-57E increasingly centres on what it is prepared to provide alongside the aircraft: localisation, joint manufacturing, configuration flexibility and access to technologies that Russia says it has historically been willing to share with India.

For New Delhi, any future consideration would have to be weighed against its emphasis on indigenous combat-aircraft development, cost, operational requirements and the effect of a foreign fifth-generation acquisition on the AMCA programme.

The Su-57E option therefore remains open from the Russian side. Alipov’s latest comments make clear that Moscow is still actively interested in bringing India into the programme — and that technology cooperation is being presented as the centrepiece of the offer.
