Reliance and Rolls-Royce to Develop Indigenous Combat Engine for India’s AMCA Program

Reliance Industries Limited and Rolls-Royce have announced a strategic intent to work together on a sovereign, indigenous combat engine for India’s Advanced Medium Combat Aircraft (AMCA) programme, a move aimed at strengthening the country’s ability to build advanced military propulsion systems at home.

The announcement was made on August 14, 2026, and outlines a proposed collaboration that would combine Rolls-Royce’s experience in advanced propulsion and engineering with Reliance’s capabilities in technology, manufacturing, scale and project execution. The two companies said the goal is to develop critical aero-engine capabilities within India.

At the centre of the plan is the possibility of creating a dedicated Aero Gas Turbine Complex in India. The facility is expected to serve as a centre of excellence for power and propulsion technologies and could cover the full chain of activity from design and development to manufacturing, testing and production of advanced aero-engines.

Anant Ambani, Executive Director of Reliance Industries Limited, said the company’s strategic focus is on building sovereign capabilities in critical technologies. He said the proposed partnership would bring together Rolls-Royce’s expertise in advanced propulsion and Reliance’s industrial and manufacturing strengths to establish an indigenous aero-engine ecosystem in India.

Rolls-Royce CEO Tufan Erginbilgic also welcomed the proposed collaboration, saying the company would combine its experience in advanced engineering and power technologies with Reliance’s industrial capabilities. According to Rolls-Royce, the partnership could help contribute to a stronger and more self-reliant aerospace ecosystem in India.

The proposed engine effort carries particular importance for the AMCA, which is India’s next-generation stealth fighter aircraft programme. A high-performance indigenous combat engine has long been one of the most demanding elements of advanced military aviation, and developing one domestically could reduce dependence on foreign propulsion technology.

If the initiative moves forward, the proposed Aero Gas Turbine Complex would aim to build capabilities across the entire propulsion ecosystem, including research and development, engineering, manufacturing, testing and production. The source said this could also help create a wider industrial base involving Indian component manufacturers, technology companies and aerospace suppliers.

The collaboration fits into India’s broader push towards Aatmanirbhar Bharat in defence and aerospace, where indigenous propulsion is viewed as a critical requirement for greater technological sovereignty in combat aviation.

If realised, the Reliance-Rolls-Royce partnership could become an important step towards building a domestic ecosystem capable of supporting advanced aero-engine development and Indian ambitions in fighter aircraft and aerospace propulsion technology.
