India's biggest warship builder, Mazagon Dock Shipbuilders Ltd (MDL), on Friday (October 17), said it has signed an exclusive Memorandum of Understanding (MoU) with Naval Group, France, on October 16 to jointly offer evolved submarines to a friendly foreign nation as part of its ongoing submarine acquisition programme.

Back in July this year, Mazagon Dock Shipbuilders had entered into a formal agreement with Naval Group for the transfer of technology to install indigenous energy system plugs on the Indian Navy’s Kalvari-class submarines.

Under the agreement, Mazagon Dock will integrate the energy system plugs, developed by Defence Research and Development Organisation (DRDO), into the Indian Kalvari submarines using technology developed by France’s Naval Group for Scorpene submarines.

The process known as Jumboisation involves precision cutting of the hull, safe insertion of the energy plug and re-joining of the structure to ensure a fully operational submarine. As the original equipment manufacturer, Naval Group will provide technical oversight, proprietary materials and specialised training to MDL engineers.

In December 2024, the Defence Ministry signed two contracts worth approximately ₹2,867 crore to enhance the operational capabilities of Indian submarines.

The first contract, valued at ₹1,990 crore, was inked with Mazagon Dock Shipbuilders for the construction of an air-independent propulsion (AIP) plug. The second contract, worth ₹877 crore, was signed with Naval Group, France, for integrating an electronic heavyweight torpedo (EHWT) system, developed in collaboration with DRDO.
