Russia Proposes Dual-Seat Su-57 Variant to India with Full Technology Transfer to Revive Stalled FGFA Partnership


In a significant move to reclaim its position as a primary aerospace partner for New Delhi, Russia has offered India an advanced dual-seat version of its Su-57 stealth fighter.

This proposal, presented during the Wings India 2026 exhibition and recent high-level bilateral engagements, includes a comprehensive "full technology transfer" (ToT) package aimed at reviving the long-dormant Fifth Generation Fighter Aircraft (FGFA) collaboration.

A Strategic Pitch to Re-engage India​

The United Aircraft Corporation (UAC) of Russia has reportedly detailed a plan that would allow India to manufacture critical components of the fifth-generation platform domestically.

This "unrestricted" offer covers high-value technologies, including:
  • Next-generation engines (specifically the Izdeliye 30 / AL-51F1).
  • AESA radar systems and advanced optical sensors.
  • Source code access, allowing for the integration of indigenous Indian weaponry like the Brahmos and Astra missiles.
  • Artificial Intelligence (AI) elements for combat automation.
India originally withdrew from the FGFA programme in 2018, citing frustrations over spiralling costs, inadequate work-share for Indian engineers, and doubts regarding the aircraft’s stealth and engine performance.

Since then, the Indian Air Force (IAF) has prioritised the indigenous Advanced Medium Combat Aircraft (AMCA).

However, with the AMCA prototype flight targeted for 2029 and mass production not expected until the mid-2030s, Russia is positioning the Su-57 as a vital "strategic bridge" to fill India's widening stealth capability gap.

The Power of Two: A New Tactical Concept​

The centerpiece of the Russian offer is a multifunctional two-seat variant, which analysts believe may be designated as the Su-57M.

Unlike American fifth-generation jets like the F-22 or F-35, which utilize single-seat configurations, Russia argues that a second crew member is essential for modern Manned-Unmanned Teaming (MUM-T).

In this arrangement, the rear-seat operator functions as a mission commander or "mini-AWACS." This officer would manage a "loyal wingman" drone swarm—such as the S-70 Okhotnik stealth UCAV—while the pilot focuses on flight manoeuvres and air-to-air engagements.

Patent documents filed by UAC describe the rear cockpit as an "airborne command post" equipped with panoramic displays designed for complex network-centric warfare.

Developmental Milestones and Future Outlook​

The Russian defence industry indicates that the airframe for this twin-seat prototype is already under assembly at the Komsomolsk-on-Amur Aircraft Plant (KnAAZ).

FeatureSpecification / Status
EngineIzdeliye 30 (AL-51F1) - Flight testing since late 2025
SpeedExceeds Mach 2; capable of sustained supercruise
RoleStealth strike, pilot training, and drone coordination
Prototype FlightProjected for late 2026 or early 2027

While the IAF has shown renewed interest in the upgraded Su-57M1E configuration, New Delhi remains cautious.

Sources suggest the IAF might prefer a limited direct purchase of roughly two squadrons (40 jets) to maintain operational readiness while ensuring that the indigenous AMCA programme remains the primary long-term focus of India’s defence strategy.

Regional Dynamics​

This renewed push comes as regional competitors accelerate their own stealth programmes.

China has successfully inducted over 200 J-20 fighters, and reports suggest it may supply the J-31/J-35 variant to Pakistan.

For India, the decision involves balancing the urgent need for a fifth-generation fleet with the desire for absolute industrial sovereignty.
 
Russia can't deliver on time
Even vikramditya was delayed 7 years and double cost over runs.
France is transparent but costly
 
No foreign deal is suitable in current condition of the world. Only AMCA and Tejas mk2 can be trusted now.
 
We Indians have the best brains and the worst too in the world. High time to erradicate hindrances and beaurcracy and just go private. Help the pvt. Induatry like you help HAL. Hal unfortunately is just a white elephant dissolve it go private not tomorrow , TODAY.

Sensible. India might get a 5G fighter 5 years earlier than AMCA Mk1.
 
L&T + BEL is going to deliver production ready AMCA in next 4 years. No need for stop gap arrangement.

Could you list the steps required for that to happen and the schedule?

At a guess

2026 Prototype builder selected
2027 Prototype contract awarded
2028 Prototype assembly started
2030 Prototype rollout
2032 Testing completed
2032 Production contract awarded
2035 First AMCA delivery

So my guess is delivery in 9-10 years. Yours is 4 years? Or 4 years + time to produce and test first production aircraft ready for delivery?

Sirji, France and the entire West have obsolete defence tech. It's in display in the Persian Golf and Ukraine. France has sent an aircraft carrier to help Israel. Strangely it is hiding somewhere in the Mediterenian. The great US carrier which as had gone into the Persian Gulf with big show. Have sailed far corners of the Indian Ocean licking their wounds. Russia is our best option as for deliveries we should makd the jet in India.Su57 is the best 5th Gen fighter in the world. None in the west have 3d thrust vectoring or can they carry as many missiles, as Su57. Hope good sense prevails. Jai Hind.

You are right about thd brains but about the pvt may not be wise. Pvt can be taken over by foreign company which is not desirable. If you have noticed only four countries have hypersonic missiles. The pvt companies in the are still struggling to have a successful test. The white elephants should be disciplined and rewarded to get the work do. PSU are owned by the citizens of India. As intelligent people we should make OUR companies are managed properly. Hope good sense prevail. Jai Hind.
 
Crying anything. HAL only wants US made engines. Let there be delay by another 100 years
To be fair to HAL, GOI/DRDO/GTRE failed to produce a working engine in time for Tejas. American and European engines are better than Russian. Is it a surprise that F404 was chosen as a substitute for Kaveri?
 
For th ex AMCA wd should have the engines from Russia. Best to keep away from the fragile, feeble obsolete ones from the west. Jai Hind.

So you think F135 is feeble and obsolete. You think the engine being developed for F-47 will be feeble and obsolete. What about the engine SAFRAN will (one hopes) develop for AMCA? Will that also be feeble and obsolete? I won't ask what you think about the engine being developed for GCAP.

A tip: if you want to persuade someone to believe your product is best, you don't do that by knocking the opposition unrealistically.

PS The 'fragile' RM12 engine is based on the' fragile' F404 used in Tejas. The RM12 engine, used in the Saab JAS 39 Gripen (C/D), is exceptionally reliable, with over 300,000 flight hours and a track record of zero in-flight engine failures.

Respected Sir, One UK air force was caught in Indian airforce Radar. After being detected the pilot claimed emergency and requested landing . (So much for their stealth,) It landed at a commercial airport in Keralam. Then a plane load ox equipment and techie and engineers flown in struggled God 37 days to the th his bird back in the air. The F35 has a affinity for water, a very significant number have taken the dive off the deep end. The also attract a log oc friendly fire. Next in all our wars including thd recent Sindoor Op. US supports Pakistan, yet were seek to please the Americans!? None of the US engine have 3d thrust vectoring. Another point to note is all western jets need pristine firl and glass smooth landing strips. Susceptible to bird hits. Hope good sense prevails. Jai Hind
