A Strategic Boost to Naval Power
On December 30, 2024, India’s Ministry of Defence (MoD) sealed two landmark contracts totaling Rs 2,867 crore, aimed at supercharging the nation’s submarine fleet. This move, part of the Atmanirbhar Bharat initiative, integrates cutting-edge Air Independent Propulsion (AIP) systems and Electronic Heavy Weight Torpedoes (EHWT), enhancing stealth and strike capabilities for the Kalvari-class submarines. As geopolitical waters turn choppy, these upgrades position India as a formidable player in the Indo-Pacific, signaling self-reliance in defense tech.
Breaking Down the Deals
The first contract, worth Rs 1,990 crore, goes to Mazagon Dock Shipbuilders Limited (MDL), Mumbai, for constructing and integrating the AIP plug for the DRDO-developed AIP system. This technology allows submarines to operate submerged for longer without surfacing for air, extending endurance from days to weeks—a game-changer for underwater missions.
The second, Rs 877 crore, is with France’s Naval Group for EHWT integration on the six Kalvari-class (Scorpene) submarines. These advanced torpedoes, with superior range and guidance, replace older systems, improving lethality against surface and underwater threats.
These deals, announced amid the Semicon India 2025 buzz, align with India’s push for indigenous manufacturing, reducing import dependence in a sector where foreign tech once dominated.
Why This Matters Now
India’s submarine fleet, vital for maritime security, faces evolving threats in the Indian Ocean. The AIP system addresses diesel-electric submarines’ key limitation—limited underwater time—while EHWT torpedoes ensure precision strikes. These upgrades, executed by domestic firms like MDL, cut costs and build expertise, with the first AIP-equipped sub expected by 2026.
Example: The Kalvari-class, already operational, gains stealth for extended patrols, crucial amid South China Sea tensions.
Table: Key Contract Details
| Contract | Value (Rs Cr) | Partner | Focus Area |
|---|---|---|---|
| AIP Plug Integration | 1,990 | Mazagon Dock Ltd. | Submerged Endurance |
| EHWT Integration | 877 | Naval Group, France | Precision Strikes |
Broader Implications for Defense
This deal reinforces India’s self-reliance, with Rs 2,867 crore invested in homegrown tech. It aligns with the 2021 Semiconductor Mission, fostering innovation in electronics for defense. Globally, it positions India against rivals, enhancing naval deterrence.
