India's naval capabilities are set to strengthen significantly with the approval of a ₹70,000 crore deal for Project 75I, which will see the construction of six advanced submarines equipped with Air-Independent Propulsion (AIP) technology. This technology enables submarines to remain submerged for extended periods, enhancing stealth and operational effectiveness. The construction will be undertaken by Mazagon Dock Shipbuilders Limited in partnership with Germany's thyssenkrupp Marine Systems, marking a significant step in India's defense manufacturing self-reliance. The first submarine is projected to be delivered seven years after the contract is finalized, with one additional submarine to be delivered each year thereafter. The project includes a commitment to increase the proportion of Indian-made components, starting at 45% for the first submarine and rising to 60% for the sixth. This initiative aligns with India's broader defense strategy and its growing collaboration with Germany in defense technology development.
