Reliance Industries and Rolls-Royce announced a strategic intent on 14 August 2026 to explore building a sovereign indigenous combat engine for India's Advanced Medium Combat Aircraft.
The proposed collaboration aims to establish an Aerospace Gas Turbine Complex in India covering design, development, and manufacturing, though no specific financial investment or contract details were disclosed.
The Ministry of Defence and DRDO are not parties to this non-binding agreement, which follows India's long-standing struggles to develop its own indigenous Kaveri engine since 1989.
