AMCA Engine Development: Powering India’s 5th Gen Fighter
India’s Advanced Medium Combat Aircraft (AMCA) program represents a historic leap toward building the nation’s first indigenous fifth-generation stealth multirole fighter jet. Central to AMCA’s exceptional performance is the development of a cutting-edge jet engine capable of meeting the stringent demands of modern aerial warfare.
Overcoming the Kaveri Engine Challenge
India’s journey began with the Kaveri engine, an ambitious project that laid important groundwork but faced challenges delivering the high thrust and reliability required for a frontline fighter. Despite these hurdles, the Kaveri program’s technological advancements paved the way for future engine innovations critical to AMCA.
The Interim Solution: Partnership with GE
To power the initial AMCA prototype, India has chosen the highly reliable General Electric F414-GE-INS6 turbofan engine. Producing about 98 kN of thrust per engine, this proven powerhouse enables the AMCA Mk1 to reach speeds up to Mach 2.15 and a combat range near 1,620 km. Although this engine lacks supercruise capability, it ensures the aircraft’s operational readiness while indigenous development continues.

The Future is Indigenous: Next-Gen Engine Development
The AMCA Mk2 aims to equip the fighter with a fully indigenous engine delivering between 110 to 140 kN of thrust, co-developed with French aerospace giant Safran under the Horizon 2047 strategic collaboration. This next-generation engine will incorporate:
- Advanced single crystal turbine blades to withstand extreme temperatures and boost efficiency.
- Afterburning turbofan technology optimized for a superior thrust-to-weight ratio.
- Features to minimize thermal and radar signatures, enhancing stealth.
- Thrust vectoring for exceptional maneuverability in combat.
This initiative is designed for full technology transfer to Indian organizations such as DRDO and the Gas Turbine Research Establishment (GTRE), empowering India to design, manufacture, and maintain these engines domestically. The decade-long development plan includes building nine prototypes, ensuring rigorous testing to meet world-class standards.

Strategic Impact and Enhanced Performance
A powerful, indigenous engine will enable AMCA to achieve supercruise—sustained supersonic flight without afterburner—reducing fuel consumption and infrared signature. This capability, combined with improved agility and stealth, will dramatically enhance the AMCA’s operational versatility, including missions such as air superiority, suppression of enemy air defenses, and electronic warfare.
Building this engine domestically reflects India’s commitment to Atmanirbhar Bharat (self-reliance) in defense technology, reducing dependency on foreign suppliers and strengthening strategic autonomy.
