New Delhi: In a major push to bolster India’s maritime security, the Indian Navy is set to induct nine next-generation submarines under the ambitious Project 75(India), or P75(I), once it receives final clearance from the Cabinet Committee on Security (CCS).
The project, estimated between ₹90,000 crore and ₹1,00,000 crore, is designed to counter the expanding naval footprint of China and Pakistan in the Indian Ocean Region (IOR).
Six AIP Submarines to Lead the Fleet
As per the current proposal, the first batch will include six submarines integrated with Air Independent Propulsion (AIP) systems. This technology allows extended submerged operations without surfacing, thereby enhancing stealth and survivability in high-risk zones.
The additional three submarines will follow about a year after the main contract is signed, in line with guidelines under the Defence Acquisition Procedure 2020. Construction is expected to begin around three years post-contract, with deliveries spread over a 10-year window.
From France to Germany: A Strategic Shift
Project P75(I) marks a shift from the ongoing Kalvari-class Scorpene submarine programme—developed in partnership with France—to a fresh collaboration between Germany’s ThyssenKrupp Marine Systems and India’s Mazagon Dock Shipbuilders Limited (MDL).
While the Scorpene-class platform has served well, future orders under that line are unlikely due to obsolescence and ongoing delays in indigenous AIP development. The Indo-German collaboration under P75(I) will incorporate advanced hull design, stealth features, and transfer of technology for critical mission systems—all produced largely in India.

Challenges Acknowledged, Strategic Edge Prioritised
Though this transition could lead to short-term losses in workforce retention and revenue at MDL—previously reliant on Scorpene contracts—the government appears committed to long-term strategic imperatives.
The newer submarines will offer broader operational capabilities, including anti-ship, anti-submarine, and land-attack roles. Enhanced endurance, cutting-edge stealth, and networked warfare readiness make them a vital upgrade for India’s submarine fleet.
Regional Deterrence in a Decade
As naval tensions escalate in the Indo-Pacific, the P75(I) submarines will play a key role in strengthening India’s undersea deterrence. With the Chinese People’s Liberation Army Navy expanding aggressively and Pakistan modernising its underwater assets, India’s move to induct nine advanced submarines marks a critical course correction.
Pending CCS approval, Project 75(I) could define the future of Indian naval warfare for the next decade.
