India’s fighter jet engine dream nears reality with Safran–DRDO push

India’s long-standing ambition to build a fighter aircraft powered by a home-grown engine is gathering momentum, with key policy decisions and industrial partnerships bringing the project closer to reality. Defence analysts believe the convergence of a proposed Safran–DRDO joint venture, the revival of indigenous engine development and greater private sector participation has transformed the idea from a political vision into a structured national programme.

Indigenous Vision Gains Shape

Prime Minister Narendra Modi had called for an Indian fighter aircraft equipped with an indigenous engine during his Independence Day address in 2025. Nearly a year later, that vision is beginning to translate into concrete steps. On the aircraft side, the Advanced Medium Combat Aircraft (AMCA) programme has entered a competitive phase, with Tata, Bharat Forge and Larsen & Toubro (L&T), each partnering with public sector companies, shortlisted for the project. Simultaneously, a proposal for a Safran–Gas Turbine Research Establishment (GTRE) joint venture to develop a new fighter engine is awaiting approval from the Cabinet Committee on Security (CCS), with clearance expected before Independence Day. The proposed engine is expected to generate 120 kN thrust initially. After prototype testing and certification, an upgraded 140 kN version is planned to power future fifth- and sixth-generation combat aircraft. Unlike earlier foreign engine acquisitions, India is expected to retain complete intellectual property rights over the design, marking a significant shift towards technological independence.

Breaking Technology Dependence

For decades, India has relied on imported fighter engines from Russia, France and, more recently, the United States. While these partnerships included varying degrees of manufacturing cooperation, the most critical technologies—including hot-section metallurgy, single-crystal blade technology and source codes—remained outside India's reach. The proposed Safran–GTRE collaboration is expected to address that gap. Defence experts argue that ownership of core technologies would provide India with greater strategic autonomy by reducing dependence on foreign suppliers for upgrades, maintenance and critical spares during crises. France had previously invited India to participate in advanced engine development programmes linked to the Rafale's M88 engine and Europe's Future Combat Air System (FCAS). However, those opportunities were not pursued, leaving India dependent on imported propulsion systems for successive generations of combat aircraft. If the current programme succeeds, India would join a select group of countries capable of designing and manufacturing advanced fighter jet engines.

Long Road To Delivery

Developing a modern fighter engine remains one of the most technologically demanding defence projects. The programme will require multiple prototypes, extensive ground and flight testing, and years of certification before operational deployment. The eventual objective is to integrate the upgraded 140 kN engine into the AMCA and future twin-engine naval fighters. Analysts view the project as a long-term investment that could fundamentally alter India's aerospace capabilities despite the lengthy development timeline.

China Raises Pressure

India's urgency is shaped partly by China's rapid advances in military aviation. Beijing has steadily progressed from reverse engineering foreign engines to developing indigenous powerplants such as the WS-10 and the more advanced WS-15. The WS-15 reportedly powers China's J-20 fifth-generation stealth fighter, which has been deployed at multiple airbases near the Line of Actual Control following tensions that escalated after 2020. Combined with platforms such as the J-10 and JF-17, China's engine development has strengthened its long-range air combat capability. Defence observers argue that India must accelerate decision-making, reduce project delays and improve execution if it hopes to narrow the technological gap.

Reviving The Kaveri Project

Alongside the Safran partnership, India is also reviving its indigenous Kaveri engine programme. The original engine achieved around 40 kN thrust, well below operational fighter requirements. The renewed effort targets an 80 kN version that could serve as a technology demonstrator while helping Indian engineers acquire critical expertise for future engine development. Modern fighter engines are estimated to cost between $10 billion and $15 billion to develop, making sustained investment essential for long-term success.

GE Partnership Continues

India's immediate fighter fleet modernisation will continue to depend on American engines. GE F404 engines will power the Tejas Mk1A fleet, while the more powerful F414 engine is planned for the Tejas Mk2 and the first AMCA squadrons. HAL and General Electric have agreed to manufacture the F414 in India, although reports suggest the technology transfer will cover only part of the overall design. As with previous engine deals, sensitive technologies such as source codes and critical metallurgy are expected to remain with the original manufacturer. Timely production under the joint venture will be crucial for maintaining India's fighter induction schedule.

Future Combat Choices

India's broader air power strategy extends beyond engine development. The Indian Air Force currently lacks an operational fifth-generation fighter, while China has already inducted the J-20. Potential acquisitions such as the American F-35 or Russia's Su-57 remain under discussion. However, recent conflicts have also highlighted the growing effectiveness of precision missiles and unmanned combat systems against expensive stealth aircraft. This has triggered a wider debate over defence priorities, balancing investments between fifth-generation fighters, long-range precision missiles and unmanned combat aerial systems (UCAS), all within limited defence budgets.

Towards Strategic Autonomy

Defence experts believe India's future air power will depend on a combination of indigenous engines, imported technologies where necessary, advanced missile systems and expanding drone capabilities.

The growing participation of private industry in aircraft manufacturing, engine development and missile production is expected to complement public sector expertise and strengthen the country's defence industrial base. The proposed Safran–GTRE programme therefore represents more than an engine development project. It is widely seen as a test of India's ability to achieve genuine technological self-reliance in military aviation and reduce long-term dependence on foreign defence suppliers.
