Indian Navy’s Mega Submarine Deal Moves Forward: Defence Update for NDA Exam Preparation (4 August 2025)
News Highlights
India is set to finalize its largest-ever defence contract under Project 75 (India) or P-75(I), aimed at procuring six advanced diesel-electric submarines. The Ministry of Defence (MoD) and Mazagon Dock Shipbuilders Limited (MDL), in partnership with Germany’s Thyssenkrupp Marine Systems (TKMS), are leading the negotiations. Valued at approximately ₹90,000–100,000 crore (US$12 billion), these submarines will significantly enhance India’s underwater warfare capabilities, with delivery expected about seven years after contract signing.
These subs will feature cutting-edge Air Independent Propulsion (AIP) technology, allowing them to remain submerged for over two weeks—an important leap from conventional diesel-electric submarines that need to surface every 2-3 days. This enhances stealth and operational endurance in blue-water naval operations across the Indian Ocean. The deal emphasizes technology transfer and indigenisation, aligning with India’s self-reliance goals under the “Make in India” initiative. This development comes amid shifting regional security dynamics, with maritime rivals expanding their naval forces.
Strategic Importance & Technological Features
- Air Independent Propulsion (AIP): Enables submarines to generate power underwater without surfacing for oxygen, extending stealth and operational periods.
- Indigenous Content: Starting at 45% for the first submarine and ramping up to 60% by the sixth, reinforcing India’s defence manufacturing base.
- Technology Transfer: TKMS will share 100% of design and technology, boosting MDL’s capacity to build future submarines domestically.
- Design Base: The submarines are based on the HDW Class 214 design, known for fuel-cell AIP systems and advanced sensors.
NDA Exam Relevance
This update is crucial for NDA aspirants because questions on India’s key defence procurements, submarine technology, and strategic security often feature in General Knowledge and Current Affairs sections. Understanding the P-75(I) program’s strategic benefits and its emphasis on indigenisation will impress during SSB interviews, where awareness of national security initiatives is valued.
