HSL achieves milestone with fastest-ever refit of EKM-Class submarine, eyes future strategic projects

New Delhi: Hindustan Shipyard Limited (HSL) has successfully completed the normal refit of an EKM-class submarine on July 21, marking a significant milestone in the country’s defence manufacturing and maintenance capabilities. The refit was completed in record time, earning commendation from the Indian Navy for being the fastest-ever refit of its kind, significantly enhancing the operational readiness of the submarine.

HSL's Chairman and Managing Director (CMD) Cmde Hemant Khatri attributed the achievement to over three decades of submarine refit expertise, the commitment of HSL’s workforce, and the robust support extended by Naval Dockyard Visakhapatnam and the Eastern Naval Command. He also underlined the role of the growing MSME vendor ecosystem, which contributed to local job creation and skill development—advancing India’s Atmanirbhar Bharat (self-reliant India) mission.

The refit included extensive work, with a landmark achievement being the modification and testing of both escape hatches for Deep Submergence Rescue Vessel (DSRV) integration. This is the first time such an upgrade has been successfully executed on a conventional submarine by an Indian ships yard.

Following this success, HSL is preparing to take up the refit of a modern Scorpene-class submarine. With this growing track record, HSL is positioning itself as a prime contender for upcoming strategic submarine programs, including the Medium Refit-cum-Life Certification (MRLC) of the Sindhughosh class and new submarine construction under the ambitious Project 75(I) and Project 76.

Strengthening its strategic capabilities, HSL has also entered into a Memorandum of Understanding (MoU) with Mazagon Dock Shipbuilders Limited (MDL) to develop dual submarine construction facilities on both the east and west coasts of India. This collaboration aims to improve fleet readiness and accelerate delivery timelines.

On the international front, HSL is in discussions with the Vietnam People’s Navy for submarine refit work, signaling India’s growing role as a trusted defence partner in the Indo-Pacific region.

With its expanding capabilities in both submarine refit and construction, HSL is emerging as a vital player in India’s defence industrial base—delivering high-quality, time-bound solutions in support of national and regional security imperatives.
