A DRDO team recently visited Naval Group France to discuss the progress of integrating an indigenous Air Independent Propulsion (AIP) system into Kalvari-class submarines. This collaboration marks a significant step towards India’s “Atmanirbhar Bharat” (Self-reliant India) initiative in the defense sector.

Last year, DRDO and Naval Group signed an agreement to equip INS Kalvari with a fuel cell-based AIP system developed by DRDO’s Naval Materials Research Laboratory (NMRL). The agreement includes certification by Naval Group to ensure the safe and effective integration of the AIP system within the submarines.

INS Kalvari is expected to enter mandatory refit at Mazagon Dock Shipbuilders Limited by mid-2025. This refit will include the installation of the AIP module, enhancing the submarine’s underwater endurance and stealth capabilities.

This joint effort between DRDO and Naval Group strengthens India’s maritime defense capabilities while promoting technological self-reliance.
