India’s second Indigenous Aircraft Carrier (IAC-2) is set to mark a significant leap in naval propulsion technology by incorporating an Integrated Electric Propulsion System (IEPS) powered by Rolls-Royce MT-30 gas turbines. This next-generation propulsion system aligns with global advancements and represents a shift from the four US-supplied LM2500 engines currently powering the IAC-1, INS Vikrant, which delivers 88 MW for a top speed of 28 knots.
The Rolls-Royce MT-30, regarded as one of the world’s most power-dense marine gas turbines, will serve as the backbone of the IAC-2’s IEPS. The MT-30’s exceptional power output has already been proven on advanced platforms such as the Royal Navy’s HMS Queen Elizabeth and HMS Prince of Wales. These aircraft carriers utilize the MT-30 in conjunction with electric propulsion systems, enabling operational flexibility, reduced noise, and enhanced efficiency.
The MT-30 gas turbine debuted in 2008 aboard the USS Freedom, a Littoral Combat Ship (LCS) of the US Navy. With its compact design and ability to generate up to 36 MW of power per turbine, the MT-30 can drive ships to speeds exceeding 40 knots when combined with diesel engines.
India and the UK have established a Joint Working Group on Electric Propulsion Capability Partnership to foster collaboration and knowledge exchange in the field of electric propulsion. This forum promotes industrial cooperation and strengthens the likelihood of Rolls-Royce propulsion systems becoming a mainstay in the Indian Navy’s future fleet, including destroyers, frigates, corvettes, and landing platform docks (LPDs).
This collaboration underscores India’s intent to transition away from traditional propulsion systems sourced from the US, Russia, and Ukraine, which currently power many of the Indian Navy’s warships. By embracing Rolls-Royce marine gas turbines, the navy aims to enhance performance, reduce maintenance costs, and align with global best practices in propulsion technology.
The adoption of Rolls-Royce’s MT-30 in IAC-2 not only modernizes India’s aircraft carrier capabilities but also sets a precedent for equipping the navy’s future vessels with advanced integrated electric propulsion systems. Such systems are valued for their operational advantages, including better fuel efficiency, reduced acoustic signature, and enhanced stealth.
