Rolls-Royce to Collaborate with Indian Navy on First Electric Warship

10 October, 2025

British engineering firm Rolls-Royce has announced its intention to partner with the Indian Navy to design and develop the country's first all-electric warship. Citing its expertise in integrated hybrid-electric and full-electric propulsion systems, such as the MT30 turbine used in the UK's aircraft carriers, the company aims to support India's naval modernisation and self-reliance goals. This collaboration marks a significant technological step for the Indian Navy, moving towards more sustainable and advanced naval power.

Unpacked:

What is the Rolls-Royce MT30 turbine, and why is it significant for naval propulsion?

The Rolls-Royce MT30 is a marine gas turbine known for its high power density and reliability, producing up to 36–40 MW per unit. It is a benchmark in modern naval propulsion, enabling fewer turbines to deliver more power, increasing efficiency, and simplifying ship design. The MT30 powers major vessels like the UK’s HMS Prince of Wales, demonstrating its capability to support demanding naval operations.

How does this partnership align with India’s broader defence and industrial goals?

This collaboration supports India’s push for naval modernisation and 'Atmanirbhar Bharat' (self-reliant India) by integrating advanced, sustainable technologies. Rolls-Royce aims to expand local supply chains and manufacturing, helping India reduce dependence on foreign defence imports and build indigenous capability in cutting-edge naval systems.

What are the potential environmental and operational benefits of all-electric warships compared to conventional ones?

All-electric warships offer reduced emissions, lower noise (improving stealth), and greater fuel efficiency. Their integrated electric propulsion allows flexible power distribution, enhancing operational reliability and enabling advanced weapons and sensor systems. Such ships are seen as a step toward more sustainable and capable naval fleets.

Have other nations adopted similar electric or hybrid-electric propulsion systems for their navies, and what has been their experience?

Yes, the UK’s Royal Navy uses integrated full-electric propulsion (IFEP) systems, notably in its Queen Elizabeth-class carriers, which are powered by Rolls-Royce MT30 turbines and diesel generators. Other nations, including the US and China, are also investing in electric and hybrid propulsion, reporting benefits in efficiency and operational flexibility, though challenges remain in scaling and maintaining such advanced systems.
