By spearheading the domestic marine gas turbine program for the Indian Navy, Bharat Heavy Electricals Limited (BHEL) has made a significant contribution to India’s progress towards propulsion self-reliance.
The goal of this project, which was authorized under the Defense Acquisition Procedure 2020’s esteemed “MAKE-I” category, is to provide a 24–28 MW class engine specifically designed for frontline warships.
The American General Electric LM2500 and the Ukrainian Zorya-Mashproekt turbines are two examples of the propulsion systems that the Indian Navy has long relied on. Although dependable, these imports exposed India to high costs, geopolitical concerns, and supply chain weaknesses.
Previous attempts at indigenization, such the Gas Turbine Research Establishment’s (GTRE) Kaveri Marine Gas Turbine project, made some headway but were unable to create an engine that could be used in an operational setting.
HAL-GE and BHEL-Zorya Mashproekt technology transfer agreements did not result in complete autonomy either. With more resources, coordination, and national focus, the new program is an innovative, all-encompassing strategy.
For destroyers, frigates, and upcoming big combatants, the target power range of 24–28 MW is essential. These ships require propulsion systems that can accelerate quickly, maintain endurance, and maneuver during combat.
Marine engines, in contrast to aviation turbines, must endure corrosive, salt-filled maritime environments and extended continuous operation, which makes indigenous development a challenging engineering task.
BHEL plays a key role by utilizing its heavy engineering experience and working with DRDO’s Naval Science and Technological Laboratory and Gas Turbine Research Establishment.
Four prototypes will be developed as part of the plan for thorough testing and assessment. A minimum order of forty engines is designated for induction into naval platforms after validation. It is anticipated that private business leaders, R&D institutions, and public sector initiatives like BHEL and HAL will play crucial roles.
Additionally, the initiative integrates high-temperature metallurgy, precise engineering, and sophisticated materials, all of which will bolster India’s broader aerospace and defense ecosystem.
By removing dependency on foreign OEMs, the domestic marine gas turbine strategically guarantees operational independence. It protects sovereignty over availability and lifecycle management, lowers long-term procurement and maintenance costs, and strengthens resilience during times of conflict when foreign supply chains can break.
If this effort is successful, it might establish India as a supplier of cutting-edge propulsion technologies and create export prospects to friendly navies around the Indian Ocean Region and beyond.
Through agreements with DRDO’s NSTL, including technology transfer for the LM2500 Gas Turbine Infrared Suppression System, which lowers infrared signatures and improves naval platform survivability, BHEL has already increased its defense footprint.
BHEL’s position as a strategic defense producer is strengthened by its diversification outside of its conventional power industry. With order inflows of almost ₹75,000 crore in FY26, the company’s solid financial performance supports its ability to complete such complicated projects.
Bharat Heavy Electricals Limited (BHEL) emphasizes its broad knowledge of gas turbine technology, especially with regard to marine applications.
With more than 230 installations globally and a history of producing Heavy Duty Gas Turbines (HDGT) with capacities ranging from 10 MW to 300 MW since 1986, the company has more than 30 years of experience in the gas turbine industry.
BHEL’s dedication to self-reliance in vital technologies is demonstrated by the complete indigenization of gas turbines up to 40 MW. The company’s integrated approach is further strengthened by its internal capacity to develop and produce gearboxes for gas turbine applications.
BHEL may use its domain expertise for naval requirements because many of the fundamental technologies used in HDGTs are immediately transferable to Marine Gas Turbines (MGTs). With this foundation, BHEL is well-positioned to help the Indian Navy over the long term and indigenize marine gas turbines.
The company’s proficiency in developing and producing metallic gas turbine blades of various sizes and forms highlights its capacity to produce precise parts that are crucial to turbine performance.
To satisfy international standards, mastery of high-pressure ratios, sophisticated cooling methods, blade metallurgy, and economical fuel use is crucial. However, the program’s organized development strategy and linkage with the Atmanirbhar Bharat goal demonstrate India’s resolve to overcome these obstacleThe domestic marine gas turbine project is a strategic step toward safeguarding India’s maritime sovereignty, not just a technical endeavor.
