India is poised to significantly enhance its naval power with a record ₹1.06 lakh crore submarine deal, aimed at modernizing its underwater fleet and solidifying its position as a global undersea power. This ambitious plan involves constructing advanced submarines equipped with cutting-edge technology, boosting the Indian Navy's capabilities in response to growing regional tensions.

Project 75I and the Air Independent Propulsion (AIP) System The centerpiece of this massive investment is Project 75I, under which Mazagon Dock Shipbuilders Limited (MDL) will collaborate with Germany's ThyssenKrupp Marine Systems (TKMS) to build six advanced conventional submarines. A key feature of these submarines will be the integration of Air Independent Propulsion (AIP) technology, enabling them to remain submerged for over two weeks, significantly enhancing their stealth and operational effectiveness. The AIP system, which allows a diesel-electric submarine to stay underwater for longer periods, is crucial for maintaining a discreet presence and avoiding detection. The submarines will be built in India, with indigenous content starting at 45% for the first boat and increasing to 60% for the sixth.

Strategic Response to Regional Challenges This substantial investment reflects India's concerns about the increasing presence of the Chinese Navy in the Indian Ocean and aims to address potential threats from both China and Pakistan. By acquiring smarter and stealthier submarines capable of extended patrols, India seeks to maintain a credible deterrent and safeguard its maritime interests.

Partnerships and Technology Transfer The collaboration between MDL and TKMS is central to this project, with the German company providing the design and technology for the submarines. This transfer of technology is expected to contribute to India's goal of self-reliance in defense manufacturing. The submarines will be based on the Class 214 and Class 212CD designs and feature operational AIP systems.

Project Timeline and Indigenous Development The first submarine under Project 75I is expected to be delivered to the Navy seven years after the contract signing, with subsequent submarines delivered at a rate of one per year. The project emphasizes indigenous manufacturing, with a progressive increase in local content, fostering domestic expertise and capabilities in submarine construction.

Additional Projects and Upgrades In addition to Project 75I, MDL is also expected to undertake an add-on project involving the construction of three additional Scorpene-class submarines. Furthermore, the Defence Ministry has signed contracts to retrofit the existing Kalvari-class submarines with AIP systems and integrate electronic heavyweight torpedoes, further enhancing their underwater capabilities.

Boosting Naval Capabilities The acquisition of these advanced submarines, coupled with the modernization of existing vessels, will significantly enhance the Indian Navy's underwater warfare capabilities. These submarines are expected to play a crucial role in maintaining maritime security, protecting trade routes, and ensuring the country's strategic interests in the region.

In summary, the ₹1.06 lakh crore submarine deal represents a major step forward in India's efforts to modernize its navy and strengthen its position as a leading maritime power. By investing in advanced technology, promoting indigenous manufacturing, and fostering strategic partnerships, India is committed to building a formidable underwater fleet capable of addressing evolving security challenges and safeguarding its national interests.
