The updated Russian aviation initiative offers India unrestricted access to the complete Su-57 family, including the two-seat Su-57D command variant, to bypass the standard operational limitations found in the earlier Su-57E export package. This strategic technology transfer is positioned to address the Indian Air Force`s current deficit of roughly 11 to 13 fighter squadrons while the domestic Advanced Medium Combat Aircraft program progresses toward its projected mid-2030s operational introduction.

On June 5, 2026, Russian President Vladimir Putin publicly said at the St. Petersburg International Economic Forum that Russia is ready to supply Su-57 fighters to India, highlighting for the first time the possibility of unrestricted access to the Su-57`s core systems rather than just the delivery of the controlled Su-57E export configuration. Russia is therefore prepared to grant complete access to source code, mission software, radar, and electronic warfare architecture, weapons integration interfaces, maintenance data, upgrade pathways, and production technologies to India, all of which are normally withheld from foreign operators.

India previously withdrew from the FGFA program largely because it was dissatisfied with the level of access and influence it would receive relative to the financial and industrial commitments required. If Moscow is now prepared to remove those restrictions and allow India to independently integrate domestic weapons, modify mission systems, conduct upgrades, and participate in future development, the proposal would represent a fundamentally different offer from earlier arrangements since India left the FGFA program in 2018. The offer matters because Putin did not limit the wording to the Su-57; he also linked the proposal to joint work, local production, Indian weapons integration, a two-seat version, and cooperation without stated limitations.

For India, that wording could radically change the current question around the potential purchase of the Su-57: whether New Delhi would receive a restricted export aircraft or obtain partial entry into the baseline Su-57 production, software, weapons, sensor, and upgrade structure. The timing is also relevant because the Indian Air Force is operating at about 29 to 31 fighter squadrons against an authorized strength of 42.5, while the AMCA, India’s planned indigenous fifth-generation fighter, is unlikely to enter operational service before the 2030s and more likely around 2035. The practical issue is therefore not only whether India needs a fifth-generation fighter before AMCA, but whether Russia can offer terms that overcome the same cost, access, performance, and industrial disputes that caused New Delhi to leave the earlier FGFA effort.

Putin’s remarks placed the offer within a long Russian-Indian combat aviation relationship. He said India has traditionally bought Russian aircraft and helicopters and added that Indian pilots are satisfied with this equipment, a reference that points to the Indian Air Force’s long use of Russian-origin combat aircraft, especially the Su-30MKI and MiG-29. He also said Russia had previously proposed joint work on the Su-57, but India did not proceed, after which Russia completed the aircraft independently. He then said Russia is now ready to supply the fighter to India, saying that "[Russia is] ready to work with India. We don`t have any issues or limitations. Same goes for air defence systems." Ezoic

Putin also referred to the Su-57D, a version with two pilots, and said such an aircraft could function as a command post, which would give a second crew member responsibility for managing sensors, weapons employment, communications, electronic warfare tasks, or coordination with other aircraft. That point is not minor because a two-seat Su-57 would be closer to the Indian Su-30MKI operating model than the Su-57 single-seat air-superiority fighter, and it could be relevant if India wants a command aircraft for mixed packages of manned fighters, strike aircraft, and unmanned systems such as the Ghatak. The Sukhoi Su-57 is Russia’s most modern fighter jet developed under the PAK FA program, while the Su-57E is the export variant intended for foreign customers.

In practical terms, an export variant of the Su-57, such as the one delivered to Algeria, would normally carry limits on radar modes, electronic warfare libraries, encryption, datalinks, mission software, weapons interfaces, source code access, and upgrade authority. For India, those limits would affect whether the stealth fighter can use Indian weapons without Russian control over each integration step, whether Indian engineers can manage mission data files, whether maintenance can be performed independently at scale, and whether future upgrades can be made inside India. A standard Su-57E purchase would likely resemble a controlled export acquisition, with Russia retaining authority over many sensitive functions.

A Su-57 joint production would be closer to the abandoned FGFA concept, especially if it includes access to mission computers, radar and EW configuration, software tools, production workshare, weapons clearance authority, and upgrade rights. The decisive content would become the contract annexes that determine what India can modify, produce, integrate, export, and sustain without returning to Moscow for every major change. The Su-57 itself is a twin-engine fifth-generation fighter developed by Sukhoi, with production at the Komsomolsk-on-Amur Aircraft Plant in Russia’s Far East. Its first flight took place on January 29, 2010, and it entered Russian service in 2020.

For now, Russia has a contract for 76 aircraft intended to equip three regiments, with deliveries planned through 2028. The fighter uses internal weapons bays to reduce radar signature during combat missions, while external stores would increase radar return and reduce the value of its low-observable shaping. Its main design features include reduced radar signature, an AESA radar complex, a supercruise requirement, thrust-vectoring engines, an electronic warfare suite, and an air-to-air and air-to-ground mission set. For India, these features would have to be assessed against maintainability, sortie generation, production quality, available weapons, engine maturity, radar performance, and the degree of Indian control over mission systems.

The Su-57’s value would be reduced if India could not integrate its own weapons or adapt the fighter to Indian operational requirements over a service life that could last three decades. The Su-57’s sensor package would be one of the first areas of Indian scrutiny. The Su-57 Felon uses the N036 Belka AESA radar suite, including a forward radar, side-looking arrays, and L-band arrays, giving it a more distributed radar layout than fighters relying only on a nose-mounted array. The aircraft’s internal carriage is central to its low-observable role because radar signature rises once large weapons or fuel tanks are carried externally. Early aircraft used AL-41F1 engines, while the second-stage engine, usually associated with Izdeliye 30 or AL-51F1, remains central to future Russian performance claims.

That engine issue matters because propulsion affects range, acceleration, supercruise, infrared signature, maintenance intervals, spare-parts demand, and lifecycle cost. The aircraft is designed for advanced Russian air-to-air and air-to-ground weapons, but Indian weapons integration would require access to software, interfaces, mission computers, weapons control architecture, and certification procedures. India would likely examine radar maturity, engine reliability, low-observable maintainability, mission-system access, and production consistency because these were also among the categories that weakened confidence during the earlier FGFA period.
