India, France to Co-Develop Engine for Home-Grown Stealth Aircraft

The CSR Journal Magazine

India has taken another major step towards strengthening its defence manufacturing sector and reducing reliance on foreign suppliers. In what is being described as a landmark partnership, India and France have agreed to jointly design and develop a powerful jet engine that will be used in the country’s next-generation stealth fighter aircraft. This project is expected to give a major boost to the indigenous defence industry while also opening a new chapter in Indo-French strategic relations.

The initiative comes at a time when India is firmly pushing its “Atmanirbhar Bharat” vision in the defence sector. While the Defence Research and Development Organisation (DRDO) and Hindustan Aeronautics Limited (HAL) have made progress in building modern fighter jets such as the Tejas, the need for a more advanced powerplant has long been felt. The proposed sixth-generation engine, developed in partnership with French aerospace giant Safran, is meant to power India’s Advanced Medium Combat Aircraft (AMCA), a stealth fighter project already in its development phase.

Experts say that the collaboration will not only involve technology transfer but also enable Indian engineers to master critical know-how in jet engine design, metallurgy, thermal management, and stealth integration. These are areas in which India has been behind major defence powers like the United States and Russia.

A Step Towards Self-reliance

The AMCA, which is being designed by the Aeronautical Development Agency (ADA) under DRDO, is planned as a fifth-generation stealth fighter with features like supercruise capability, advanced avionics, and reduced radar cross-section. However, the biggest challenge has always been the engine, which remains the most complex component of any modern fighter aircraft. Without a reliable, high-thrust engine, the indigenous stealth jet project could face delays or performance limitations.

France’s Safran was identified as a natural partner owing to its decades of expertise in military jet engines. The new powerplant will reportedly deliver upwards of 110 kiloNewtons of thrust, putting it in the same league as engines used in advanced Western fighters. The design work is expected to be shared, with Indian laboratories and production units playing a leading role in prototype development and eventual manufacturing.

This cooperation builds upon the already deep-rooted bilateral defence ties. India has been one of the largest international users of French aircraft, including the Mirage 2000 fleet that played a crucial role in the Balakot operation, and most recently, the Rafale jets inducted into the Indian Air Force (IAF).

Indo-French Defence Ties

Observers note that this deal goes beyond just defence trade. Unlike traditional arrangements where India has purchased equipment off the shelf, this collaboration represents a shift towards co-creation. France has agreed to a level of technology sharing that even some of its closest allies have not received in the past. For New Delhi, this is a diplomatic achievement and a sign of growing trust.

Meanwhile, for Paris, the deal ensures long-term engagement with one of the world’s largest defence markets. The French government has, in recent years, been keen to expand its footprint in Asia, and India stands out as both a reliable partner and an emerging economic power.

This engine project is also being seen as a strategic counter to the growing military-technological dominance of China in the region. As Beijing accelerates its fighter and engine production, India’s ability to develop a self-sufficient aerospace ecosystem becomes critical for national security.

Growing Optimism

While the announcement has generated excitement, experts caution that the journey from agreement to final product will not be easy. Jet engine development is notoriously difficult, requiring mastery over high-temperature materials, precision manufacturing, and long test cycles. India’s own past efforts in this field, such as the Kaveri engine project, faced multiple hurdles and remained short of service-ready standards.

However, officials insist that the partnership with France will bridge these gaps. With timelines aligned to the rollout of the AMCA, the first prototypes could be ready for ground tests in a few years. If successful, the collaboration could place India in the small and elite group of nations that design and produce world-class jet engines domestically.

For now, the development signals India’s determination to build on its recent defence modernisation gains. By working with France to develop technology that will power its first stealth fighter, New Delhi is sending a clear message: the future of Indian defence will be increasingly shaped at home, albeit with trusted partners by its side.
