India is reportedly engaged in advanced discussions with Russia over the potential acquisition of the Su-57E, the export variant of Moscow’s fifth-generation stealth fighter jet. If finalized, the deal would mark a watershed moment for the Indian Air Force (IAF), which has long sought to fill its fifth-generation capability gap.
What makes this development particularly significant is the possibility of pairing the Su-57E with Russia’s cutting-edge 3M22 Zircon hypersonic missile. Such a combination—stealth fighter plus Mach 9 missile—would alter the strategic equation in South Asia and beyond, potentially reshaping how India projects power and deters adversaries.
While India has traditionally balanced Russian military platforms with Western acquisitions, the reported talks underscore New Delhi’s enduring reliance on Moscow for advanced combat aviation technology, even as India simultaneously develops its own next-generation programs.
The Su-57E is Russia’s flagship fifth-generation fighter, designed to rival the U.S. F-22 Raptor and F-35 Lightning II. Its key characteristics:
-
Stealth technology: Advanced shaping, radar-absorbent coatings, and internal weapons bays to reduce radar cross-section.
-
Supercruise capability: Ability to sustain supersonic speeds without afterburners, improving efficiency and combat endurance.
-
Advanced avionics and sensors: Integration of active electronically scanned array (AESA) radar, infrared search-and-track (IRST) systems, and sensor fusion for enhanced situational awareness.
-
Multirole functionality: Designed for both air superiority and precision ground-attack missions.
For the IAF, which currently operates fourth-generation fighters like the Su-30MKI, Mirage-2000, MiG-29UPG, and Rafale, the Su-57E would fill a glaring void. India has no operational fifth-generation aircraft, despite ambitions for its indigenous Advanced Medium Combat Aircraft (AMCA).
With China deploying its J-20 stealth fighter in increasing numbers and Pakistan leaning heavily on Chinese military support, the absence of a fifth-generation fighter in India’s arsenal has become a strategic vulnerability.
While the Su-57E alone would boost India’s air power, it is the potential integration of the 3M22 Zircon hypersonic missile that makes this prospective deal revolutionary.
-
Speed: Capable of reaching Mach 8–9 (over 11,000 km/h), reducing enemy reaction time to mere seconds.
-
Range: Reported to exceed 1,000 kilometers, enabling stand-off strikes deep into hostile territory.
-
Maneuverability: Scramjet propulsion and high-altitude flight path make interception extremely difficult, if not impossible, with existing air defence systems.
-
Versatility: Originally developed as an anti-ship missile, the air-launched Zircon variant can also strike high-value land targets.
If deployed aboard the Su-57E, the Zircon would offer India a first-strike capability against key adversary targets—airbases, radar stations, naval vessels, and command centers—without exposing the launching aircraft to enemy air defences.
Russian media has hinted at successful test integrations of the Zircon with the Su-57 platform. If confirmed, this pairing would represent one of the most formidable offensive packages in global military aviation.
India’s interest in the Su-57E and Zircon must be viewed against the backdrop of intensifying regional competition:
-
China’s air power expansion: The People’s Liberation Army Air Force (PLAAF) has fielded increasing numbers of J-20 stealth fighters, alongside H-6K bombers armed with long-range cruise missiles. China is also investing heavily in hypersonic weapons, having demonstrated systems like the DF-17 ballistic missile with hypersonic glide vehicle.
-
China–Pakistan military nexus: Pakistan remains the largest importer of Chinese arms, according to the Stockholm International Peace Research Institute (SIPRI). The jointly developed JF-17 fighter is undergoing continuous upgrades, while reports suggest future collaboration on more advanced aircraft.
-
Two-front challenge for India: The prospect of simultaneous confrontation with both China and Pakistan has driven India to accelerate defence modernization. The Doklam standoff (2017), Galwan clashes (2020), and repeated border skirmishes underline the volatility of India’s security environment.
In this setting, the Su-57E–Zircon combination offers India not just parity, but potentially a qualitative edge over regional adversaries.
-
Deterrence through uncertainty
The ability to strike undetected and at hypersonic speeds complicates adversary planning. Even if India never uses the system in combat, the mere existence of such a capability would force rivals to reconsider aggressive actions. -
Extended reach in the Indian Ocean
India has long sought to strengthen its dominance in the Indian Ocean region, where Chinese naval activity has been rising. Su-57E fighters armed with Zircon missiles could strike Chinese vessels far from Indian shores, bolstering India’s maritime deterrence. -
Power projection
Beyond deterrence, the platform would allow India to project power deep into hostile territory, supporting India’s aspirations as a regional security provider and counterweight to China. -
Technological leap
Operating a stealth fighter–hypersonic missile combination would place India in an exclusive club, currently led by the U.S., Russia, and China. It would also expose Indian engineers and tacticians to advanced concepts of networked, fifth-generation warfare.
A particularly noteworthy element of the reported discussions is the possibility of local manufacturing in India. This would align with Prime Minister Narendra Modi’s “Make in India” initiative, aimed at bolstering domestic defence production.
-
Role of Hindustan Aeronautics Limited (HAL): Having previously assembled the Su-30MKI under license, HAL could leverage its experience to participate in Su-57E production.
-
Technology transfer: If Russia agrees to significant transfer of technology, it would enhance India’s indigenous capabilities, potentially benefiting the AMCA program as well.
-
Indigenous customization: Local assembly would allow integration of Indian-made avionics, sensors, and weapons, reducing long-term dependence on foreign suppliers.
However, Russia has historically been cautious about transferring its most sensitive technologies, especially for cutting-edge systems like stealth coatings and engine design. Negotiations on these issues are likely to be complex and protracted.
While the strategic appeal is clear, several challenges could complicate India’s decision:
-
Cost considerations
Fifth-generation fighters are notoriously expensive. The Su-57 program itself has been plagued by delays and cost overruns. India will need to balance this investment against other priorities, including the indigenous AMCA project and acquisition of additional Rafales. -
Technology transfer hurdles
Russia may hesitate to share its most advanced stealth or hypersonic technologies. Without sufficient transfer, local assembly could be limited to lower-end tasks, undermining the “Make in India” vision. -
Integration with Indian systems
The IAF places a premium on interoperability with existing platforms and indigenous systems. Integrating Indian avionics, electronic warfare suites, and weapons into the Su-57E could pose technical hurdles. -
U.S. factor
India’s deepening defence ties with the United States complicate matters. Washington has sanctioned countries for purchasing Russian systems under CAATSA (Countering America’s Adversaries Through Sanctions Act). While India previously avoided sanctions after acquiring the S-400 system, the risk remains. -
AMCA dilemma
India’s indigenous Advanced Medium Combat Aircraft (AMCA) project aims to field a fifth-generation fighter by the early 2030s. Critics argue that investing heavily in the Su-57E could divert resources and focus away from AMCA.
Defence analysts are divided on the merits of India acquiring the Su-57E and Zircon package.
-
Supportive voices argue that India cannot afford to wait for AMCA, given the rapid modernization of Chinese and Pakistani forces. The Su-57E provides an immediate solution.
-
Skeptical voices warn against overreliance on Russia, whose defence industry faces sanctions and resource constraints due to the Ukraine conflict. They also highlight the risk of technological dependence undermining India’s long-term self-reliance goals.
Air Marshal (Retd.) Anil Chopra, a noted Indian defence commentator, recently wrote that while the Su-57E could provide India with a fifth-generation stopgap, “the IAF must remain focused on building indigenous capability through AMCA and related projects.”
India’s defence procurement strategy has long been characterized by balancing foreign buys with indigenous development. The Su-57E–Zircon option fits this pattern but raises familiar dilemmas: immediate capability versus long-term self-reliance, Russian partnerships versus U.S. alignment, and budget constraints versus strategic necessity.
The decision will not be taken lightly. With India’s regional rivals pressing ahead with advanced systems, however, the pressure to move quickly is greater than ever.
The reported talks between India and Russia on the Su-57E stealth fighter and Zircon hypersonic missile represent more than a procurement decision. They touch on the very future of India’s air power, its strategic posture in Asia, and its role in the emerging global military balance.
If finalized, the acquisition would place India among a select group of nations capable of fielding stealth fighters armed with operational hypersonic weapons. It would strengthen deterrence against China and Pakistan, enhance India’s ability to project power in the Indian Ocean, and accelerate the modernization of the IAF.
