Proposed Aerospace Gas Turbine Complex aims to build end-to-end propulsion capabilities for India’s fifth-generation fighter programme
Reliance Industries and Rolls-Royce have announced a strategic intent to partner on the design, development, manufacturing and long-term support of an indigenous combat engine for India’s Advanced Medium Combat Aircraft (AMCA) programme, marking a significant step in the country’s ambition to build sovereign propulsion capabilities for its next-generation fighter aircraft.
The proposed collaboration combines Rolls-Royce’s advanced aero-engine expertise with Reliance’s manufacturing and industrial execution capabilities, while supporting India’s broader Atmanirbhar Bharat vision of strengthening domestic defence and aerospace manufacturing.
Building a sovereign propulsion ecosystem
As part of the proposed partnership, the two companies will explore establishing a dedicated Aerospace Gas Turbine Complex in India. The facility is envisioned as a centre of excellence for power and propulsion technologies, bringing together capabilities across engine design, development, manufacturing, testing, production and through-life support.
Unlike traditional manufacturing partnerships focused solely on production, the proposed complex aims to create an integrated propulsion ecosystem that supports military aerospace programmes throughout their operational lifecycles.
For the aerospace aftermarket, this is particularly significant, as indigenous engine development creates opportunities not only in manufacturing but also in long-term maintenance, repair and overhaul (MRO), component support, testing infrastructure, spare parts production and lifecycle sustainment.

A major step for the AMCA programme
The Advanced Medium Combat Aircraft is India’s flagship fifth-generation stealth fighter programme and is expected to play a central role in the Indian Air Force’s future combat fleet. The government has increasingly opened the programme to greater private-sector participation as it seeks to accelerate development and reduce dependence on imported defence technologies.
The Reliance-Rolls-Royce announcement comes as India continues to reshape its defence industrial model by encouraging collaborations between domestic companies and global technology leaders for strategically important programmes.
Leadership sees long-term capability building
Commenting on the partnership, Anant Ambani, Executive Director of Reliance Industries, said India’s strategic autonomy requires sovereign capability in critical propulsion technologies, adding that the collaboration aims to combine Rolls-Royce’s world-leading engine expertise with Reliance’s manufacturing scale to build an indigenous aero-engine ecosystem.
Tufan Erginbilgic, CEO of Rolls-Royce, described the proposed partnership as an opportunity to combine the company’s advanced propulsion expertise with Indian industrial capabilities, saying the collaboration could become an important milestone in strengthening India’s aerospace ecosystem.
While the announcement centres on future engine development, its implications extend across the aerospace aftermarket.
Combat engines require decades of sustained support, including depot-level overhauls, component repair, performance upgrades, testing, digital health monitoring and logistics support throughout their service life. Building these capabilities domestically would strengthen India’s defence MRO ecosystem while reducing long-term reliance on overseas sustainment.
The proposed Aerospace Gas Turbine Complex could also create opportunities for specialised suppliers, advanced manufacturing companies, testing facilities and skilled workforce development, reinforcing India’s ambition to emerge as a global aerospace manufacturing and maintenance hub.
As India’s defence aviation programmes become increasingly indigenous, propulsion technology is emerging as one of the country’s most strategically important frontiers—and this partnership signals another step toward building a self-reliant aerospace ecosystem that extends well beyond aircraft production into lifetime engine support.
