AMCA Mk2 Delay Explained: Safran–GTRE 120 kN Engine Timeline

As India accelerates its push toward self-reliance in aerospace and defence, the Advanced Medium Combat Aircraft (AMCA) remains the crown jewel of the country’s fifth-generation fighter ambitions.

However, fresh developments suggest that the AMCA Mk2, the more powerful and fully indigenous variant, could face significant delays—potentially pushing its induction close to 2040.

The primary reason lies not in the airframe, but in the complex and time-intensive development of a next-generation indigenous engine.

Engine Timelines Cast Shadow on AMCA Mk2 Induction

The possible delay stems from revised timelines of the 120 kN-class indigenous fighter engine, being jointly developed by France’s Safran and India’s Gas Turbine Research Establishment (GTRE). This engine is critical for the amca mk2, which was earlier expected to enter service in the mid-to-late 2030s.

While the Safran–GTRE partnership remains strategically vital for India’s long-term defence self-reliance, sources indicate that formal government clearance for the engine programme is now likely only by 2026. This shift has created uncertainty around the AMCA Mk2’s original induction schedule.

Extended and Complex Engine Development Path

According to programme-linked sources, development of the high-thrust turbofan has entered a longer and more technically demanding phase than initially anticipated. The first ground run of the engine’s ‘Dry Core’ configuration is now planned for 2032.

This will be followed by testing of both ‘Dry’ and ‘Wet’ (afterburning) engine prototypes in late 2032 or early 2033, marking the beginning of full propulsion validation. Defence experts caution that these early tests represent only the starting point of a lengthy certification journey.

Flight Testing and Certification Beyond the 2030s

After ground validation, the engine must undergo a demanding series of aerial trials, including:

• Flight envelope expansion
• Thermal and structural stress validation
• Reliability and endurance testing
• Integration with AMCA Mk2 avionics and flight control systems

Even without major design setbacks, sources suggest that engine certification may not conclude before 2037–38, making an indian amca mk2 engine deal induction before 2040 increasingly difficult.

AMCA Mk2: Key Features (Planned)

The AMCA Mk2 is envisioned as a true fifth-generation stealth fighter with enhanced performance and survivability:

• Low-observable stealth design with internal weapons bays
• Supercruise capability enabled by high-thrust engines
• Advanced AESA radar and sensor fusion
• AI-assisted avionics and network-centric warfare capability
• Improved payload and range compared to Mk1
• Designed for deep-strike, air dominance, and penetration missions

Safran–GTRE 120 kN Engine: What Makes It Critical

India is reportedly close to finalising one of its most ambitious aerospace programmes ever—the co-development of a 120–140 kN fighter engine with complete technology transfer and full Indian ownership.

Key features of the Safran–GTRE engine include:

• High thrust (120–140 kN class) suitable for 5th-generation fighters
• Full authority digital engine control (FADEC)
• Advanced hot-section and turbine blade technology
• Designed, tested, and manufactured entirely in India
• Tailored specifically for AMCA and future Indian fighters

If realised, this programme would place India among a select group of nations capable of independently designing and producing high-performance fighter jet engines.

Strategic Significance Despite Delays

While the extended timeline may delay the AMCA Mk2’s operational debut, the long-term gains are substantial. Engine independence remains one of the last major technological gaps in India’s aerospace ecosystem.

Safran’s expertise, amca engine combined with India’s expanding R&D and manufacturing base, could ultimately deliver a bespoke, world-class engine aligned perfectly with Indian requirements.

In strategic terms, a delayed but fully indigenous AMCA Mk2 may still prove far more valuable than a quicker solution dependent on foreign propulsion—marking a decisive step toward true aerospace self-reliance.
