Sukhoi vs F-35: Which Fighter Jet Should India Choose?
Introduction
India is continuously modernizing its air force to maintain aerial superiority against evolving threats. With the rising tension in geopolitics and regional security challenges, the selection of a new fighter jet is a critical decision. Two major contenders often discussed in defense circles are Russia’s Sukhoi Su-57 and the US-made F-35 Lightning II. But which one is better suited for the Indian Air Force (IAF)? This blog explores the capabilities, advantages, and challenges of each fighter jet to determine the best option for India’s defense strategy.
Overview of Sukhoi Su-57
The Sukhoi Su-57, developed by Russia’s United Aircraft Corporation, is a fifth-generation stealth multirole fighter. Designed for air superiority and ground attack missions, it is the most advanced Russian fighter aircraft.
Key Features:
- Stealth Capabilities: Reduced radar cross-section (RCS) for enhanced survivability.
- Supercruise: Can sustain supersonic speeds without afterburners.
- Advanced Avionics: Equipped with AESA radar and electronic warfare (EW) systems.
- Maneuverability: Highly agile with thrust vectoring engines for superior dogfighting.
- Armament: Can carry long-range air-to-air missiles, hypersonic weapons, and ground-attack munitions.
Advantages:
✔ Cost-effective compared to the F-35.
✔ Compatible with India’s existing Russian defense systems like S-400 and Su-30MKI.
✔ Excellent maneuverability in close combat situations.
✔ Greater weapons payload capacity.
Disadvantages:
✖ Limited stealth capabilities compared to Western counterparts.
✖ Delays in production and lack of operational experience.
✖ Less advanced avionics and sensors than the F-35.
Overview of F-35 Lightning II
The Lockheed Martin F-35 is one of the world’s most advanced stealth multirole fighters, developed under the Joint Strike Fighter (JSF) program. It is known for its cutting-edge network-centric warfare capabilities.
Key Features:
- Full Stealth Design: Extremely low radar signature.
- Advanced Sensor Fusion: Shares real-time battlefield intelligence with allied forces.
- Supercomputing & AI Integration: AI-powered predictive maintenance and combat strategies.
- Vertical Takeoff and Landing (VTOL) (F-35B variant): Enables operations from aircraft carriers.
- State-of-the-art Avionics: High-end AESA radar, electro-optical targeting, and sensor fusion.
Advantages:
✔ Superior stealth compared to the Su-57.
✔ Best-in-class situational awareness with data-sharing capability.
✔ Proven combat performance with NATO and allied forces.
✔ Access to advanced Western weapons technology.
Disadvantages:
✖ Extremely expensive ($80-100 million per unit).
✖ High maintenance costs and complex logistics.
✖ Restrictions on technology transfer due to US export policies.
Suitability for India
India’s fighter jet acquisition must align with its strategic goals, budget constraints, and geopolitical alignments. Below is a comparative analysis based on critical factors:
Operational Requirements
- The IAF needs a combination of stealth, agility, and multi-role capabilities.
- Su-57 offers high maneuverability, while F-35 excels in stealth and network warfare.
Cost & Maintenance
- Su-57 is more affordable with lower lifecycle costs.
- F-35 has high procurement and maintenance expenses.
Technology & Upgrades
- India prefers technology transfer and co-development, which Russia is more willing to offer.
- The US restricts technology sharing with the F-35.
Geopolitical Considerations
- India has strong defense ties with Russia, but Western alliances are growing.
- Buying F-35 may impact India’s defense deals with Russia (S-400, Su-30MKI, BrahMos missiles) due to US sanctions (CAATSA law).
Alternative Options for India
Apart from the Su-57 and F-35, India is considering:
- AMCA (Advanced Medium Combat Aircraft) – India’s indigenous fifth-gen fighter under development.
- Dassault Rafale – Proven in combat, already in IAF service.
- Eurofighter Typhoon – Another advanced European option.
- F-15EX & F/A-18 Super Hornet – High-end American fourth-gen fighters.
Final Verdict: Which Fighter Jet Should India Choose?
India’s decision depends on a balance between affordability, technology access, and operational needs:
- If India prioritizes stealth and advanced avionics, the F-35 is the better choice.
- If India values cost-effectiveness, high maneuverability, and strategic independence, the Sukhoi Su-57 is a practical option.
- India may also focus on developing its own AMCA for long-term self-reliance.
Conclusion
India’s air power strategy must factor in both immediate needs and long-term defense goals. While the F-35 offers unparalleled stealth and network capabilities, the Su-57 provides affordability and strategic flexibility. Given geopolitical realities and India’s defense policy, a combination of Rafale, AMCA, and advanced upgrades to existing aircraft may be the best path forward. The final decision will shape India’s air dominance for decades to come.
