The Indian Navy is set to enhance its submarine fleet with the completion of the Medium Refit with Life Certification (MRLC) for the Sub-Surface Killer (SSK) class submarine, INS Shishumar. Sanjeev Singhal, the Director of Finance at Mazagon Dock Shipbuilders Limited (MDL), recently confirmed that the retrofitting process for INS Shishumar is expected to conclude by the end of this year.

INS Shishumar, the first submarine in its class, has been a stalwart in the Indian Navy since its induction. Built by MDL in 1992, it continues to serve the nation more than 25 years later. The MRLC process aims to not only extend the submarine’s operational life but also equip it with a modernized weapon suite.

The ongoing retrofit of INS Shishumar involves the integration of a new weapon suite, enhancing its combat capabilities. The submarine will be armed with Harpoon Anti-Submarine Countermeasure systems, contributing to its anti-submarine warfare capabilities.

In a parallel development, the Ministry of Defence signed a contract on June 30, 2023, for the MRLC of another SSK class submarine, INS Shankush. This submarine, also built by MDL in 1994, will be undergoing a comprehensive refit that includes life certification. Upon completion, INS Shankush will join the active fleet with upgraded combat capabilities, further strengthening the Indian Navy’s underwater prowess by 2026.
