India’s search for a fifth-generation stealth fighter has gained momentum as Russia formally proposed co-development and manufacturing of the Su-57 with full technology transfer. The offer, made under the “Make in India” framework, includes initial delivery of ready aircraft followed by local production with Hindustan Aeronautics Limited (HAL).

Russian President Vladimir Putin has indicated that there are “no restrictions” on cooperation, including sharing of critical software source code. This would allow India to integrate indigenous weapons and electronic systems, significantly increasing operational flexibility.

The proposal comes at a crucial time when the Indian Air Force currently lacks any operational fifth-generation fighter aircraft, while neighbouring countries continue to advance their stealth capabilities.

Cost Advantage vs Rafale

The Su-57 is estimated to cost between $35 million and $50 million per unit, making it significantly cheaper than many Western stealth aircraft. However, defence analysts caution that the total cost of ownership is much higher once weapons, maintenance, training, and infrastructure are included.

India’s 2016 deal for 36 Rafale jets, signed with France, was valued at approximately ₹59,000 crore, translating to around ₹1,640 crore per aircraft when including full support systems and India-specific upgrades.

Dassault Rafale remains one of India’s most advanced combat platforms, but the Su-57 proposal is being seen as a potential lower-cost entry into fifth-generation technology.

Fifth-Generation Fighter Gap

India’s indigenous Advanced Medium Combat Aircraft (AMCA) program is still under development and is expected to enter service in the 2030s. Until then, the Indian Air Force faces a capability gap in stealth aviation.

Currently, only three countries—the United States, China, and Russia—operate or produce fifth-generation fighter jets. The US F-35 remains the most widely exported stealth aircraft globally, with multiple allied nations already operating it.

Russia’s pitch is strategically positioned at a time when China is also advancing its J-35 stealth fighter program, increasing regional competition in air superiority technologies.

India’s Strategic Calculus

India has historically been cautious about fully committing to US stealth fighter programs due to restrictions on technology access and operational flexibility. American platforms, while highly advanced, often come with strict usage and integration limitations.

The Su-57 offer, on the other hand, is being promoted as a more open architecture system, potentially allowing India to modify and localize systems under its defence production ecosystem.

However, defence experts note that the aircraft’s actual performance record, production scale, and engine reliability remain key factors that India will need to evaluate before making any decision.
