Project-75I: India’s $8 Billion Submarine Modernization and Its Impact on Relations with Pakistan and China | India News

Introduction

NEW DELHI: More than five decades after Indian naval strikes crippled Karachi during the 1971 war, undersea power is once again at the heart of New Delhi’s strategic thinking. The urgency around discussions of Project-75I has intensified, especially with German Chancellor Friedrich Merz’s visit amid a volatile security climate.

Understanding Project-75I

Project-75I is the Indian Navy’s flagship initiative aimed at building six ultra-modern diesel-electric submarines equipped with fuel-cell-based air-independent propulsion. This initiative stems from historical lessons learned, recent tensions with Pakistan, and China’s growing submarine presence in the Indian Ocean.

Significance of the Project

The Ministry of Defence issued a Request for Proposal in July 2021 under the Strategic Partnership Model. The project’s estimated cost, once over Rs 40,000 crore, is now projected at about $8 billion. This investment addresses a critical gap in India’s ageing conventional submarine fleet amidst increasing undersea activity from regional adversaries.

The Choice of German Type-214NG Submarine

The Indian Navy has opted for the German Type-214 Next Generation submarine over Spain’s S-80 Plus due to the maturity of the German fuel-cell-based AIP system, enhanced acoustic stealth, and comparatively lower lifecycle risks. AIP technology allows submarines to remain submerged for extended periods, reducing detection risks in contested waters.

Commitment to Indigenous Development

Under the proposed framework, MDL will build all six submarines, with TKMS providing the necessary design and engineering support. The project aims for a significant rise in indigenous content, starting at 45% and aiming for nearly 60% by the final vessel, aligning with the Atmanirbhar Bharat initiative.

The Historical Context of Naval Power

India’s push for enhanced undersea capabilities is deeply intertwined with historical lessons, notably from the 1971 war when the Indian Navy’s operations against Karachi significantly influenced land operations. This historical precedent underscores the strategic necessity of maritime control.

China’s Expanding Influence

The presence of Chinese submarines in the Indian Ocean and the assistance provided to Pakistan in upgrading its submarine fleet compels India to strengthen its naval capabilities. Project-75I is pivotal in ensuring India maintains a robust undersea presence.

Strategic Timing of Diplomatic Engagements

The timing of Chancellor Merz’s visit aligns with Germany’s wider intent to solidify its strategic engagements in the Indo-Pacific. For India, the submarine deal represents a shift towards diversifying defence partnerships, moving beyond traditional suppliers.

Future Prospects and Impacts

With the induction of the six Type-214NG submarines, the Indian Navy will significantly bolster its covert surveillance, sea denial, and precision strike capabilities. Additionally, the technological advancements from this project promise to strengthen India’s domestic submarine-building capabilities, paving the way for future indigenous designs.

Conclusion

Project-75I marks a transformative phase for India’s naval strategy. It not only addresses past lessons and current challenges but also sets the stage for future indigenization efforts in submarine technology. The current negotiations with Germany reflect the broader strategic vision of India as it navigates its maritime challenges in an increasingly complex regional landscape.
