The Project 75I program promises to transform the Indian Navy’s submarine fleet with next-generation capabilities and endurance. The Indian Ocean Region is heating up with strategic competition, making submarine modernization not optional but essential.
Mazagon Dock Limited (MDL) has decisively defeated Larsen & Toubro (L&T) in the P75I submarine program by doing what truly mattered, successfully proving the Air Independent Propulsion (AIP) system in real operating conditions. While L&T couldn’t meet this crucial requirement, MDL delivered where it counted.
What also worked in MDL’s favor is its well-established shipbuilding infrastructure, which gives it the ability to meet the Navy’s timelines without delays. Today, MDL can build up to nine submarines at the same time a remarkable capability that goes beyond just industrial strength. It’s a national asset, supporting India’s growing self-reliance in defense manufacturing.
Why Project 75I Is Critical for Indian Navy’s Future
India’s submarine force currently lacks air-independent propulsion (AIP), a vital technology for modern undersea warfare. With Project 75I, the Indian Navy aims to bridge this technological gap and increase its credibility as a capable submarine power. AIP-equipped submarines offer longer underwater endurance and greater operational range, improving stealth and survivability.
MDL Leads Project 75I as L&T Exits the Race
Initially, two Indian shipyards competed for Project 75I: Mazagon Dock Shipbuilders Limited (MDL) with Germany’s ThyssenKrupp Marine Systems, and Larsen & Toubro (L&T) with Spain’s Navantia. However, L&T failed to meet technical requirements and now stands disqualified.
MDL remains the only Indian shipyard with proven submarine-building experience. It delivered two HDW submarines in the 1990s and six Kalvari-class submarines under Project 75. That unmatched record positions MDL as the sole contender in the current program.
L&T Misses Its Submarine-Building Opportunity
L&T hoped to enter the submarine manufacturing segment through Project 75I. Their objective was to win the contract, if not then secure a workshare arrangement despite being aligned with a rival OEM. However, such an arrangement could create ethical concerns and legal complexities. L&T has not responded to Alpha Defence’s request for clarification on this matter.
Delays May Hurt Indian Navy’s Readiness
Project 75I has already seen multiple delays. Now, fresh attempts to renegotiate the workshare risk pushing timelines even further. As a result, the Navy’s operational readiness could take a serious hit. Recognizing this, the Ministry of Defence has stepped in. It now appears focused on cutting red tape and accelerating the process. By streamlining procurement, the government aims to meet critical naval requirements without more disruption. Every lost month adds pressure on the Navy, especially with growing challenges in the Indo-Pacific.
