HSL Completes Fastest-Ever EKM-Class Submarine Refit, Boosting Indian Navy’s Combat

Hindustan Shipyard Limited (HSL) successfully completed the normal refit of an EKM-class submarine on 21 July 2025, setting a benchmark in quality and turnaround time. The Indian Navy lauded HSL for the fastest-ever completion of such a complex refit, significantly enhancing the vessel’s combat readiness. Speaking on the occasion, Cmde Hemant Khatri, C&MD of HSL, emphasized that this success reflects HSL’s unmatched capabilities—built over three decades of submarine refit experience, the dedicated efforts of HSL employees, and the invaluable support from Naval Dockyard Visakhapatnam and the Eastern Naval Command.

He further highlighted that the development of a strong MSME vendor base during the refit has fostered local economic growth, job creation, and skill development, aligning with India’s vision of *Atmanirbhar Bharat*. The refit involved extensive work. One of the most remarkable accomplishments was the modification and testing of both escape hatches for DSRV integration—a first-ever feat for any conventional submarine refitted by an Indian shipyard. Building on this success, HSL is now gearing up for the refit of a Scorpene-class submarine, showcasing its ability to handle modern, high-end platforms. This track record makes HSL a frontrunner for upcoming strategic programs such as the Medium Refit-cum-Life Certification (MRLC) of the Sindhughosh class and submarine construction under Projects P75(I) and P76. A recent MoU with MDL marks a strategic alliance to create dual submarine construction capabilities across India’s east and west coasts—crucial for fleet readiness and faster project delivery.
