Mazagon Dock completes game-changing Vaghsheer submarine project for Indian Navy

Mazagon Dock Shipbuilders Limited (MDL), a key player in India’s defence manufacturing sector, marked a significant milestone on January 9, 2025, with the delivery of Vaghsheer, the sixth and final Scorpene-class submarine under Project P-75. This milestone represents a major advancement in India’s self-reliance in defence and aligns with the government’s ‘Make in India’ initiative, reinforcing the nation’s position as a formidable force in naval capabilities.

Vaghsheer, which will soon be commissioned as INS Vaghsheer, underwent rigorous trials to meet the Indian Navy‘s demanding operational standards. This achievement not only signifies the culmination of years of technical expertise and strategic planning but also underscores India’s entry into the exclusive group of nations capable of designing and building state-of-the-art submarines.

A Transformative Addition to India’s Naval Strength

The delivery of Vaghsheer strengthens the Indian Navy’s operational capabilities, enhancing its readiness for modern maritime challenges. The submarine is equipped with advanced stealth technology, including acoustic absorption techniques, low radiated noise levels, and a hydrodynamically optimized design. These features provide superior underwater concealment, allowing it to evade detection and remain effective during critical missions.

Designed to execute a range of missions, Vaghsheer is capable of anti-surface warfare, anti-submarine warfare, intelligence gathering, area surveillance, and more. Its integration into naval task forces makes it a potent platform for strengthening India’s maritime dominance. The submarine’s design emphasizes operational versatility, allowing it to perform seamlessly in diverse theatres of operation, including deep-sea and littoral zones.

Cutting-Edge Technology and Indigenization

Vaghsheer incorporates state-of-the-art systems that underscore India’s technological advancements in defence. It is outfitted with a sophisticated Integrated Platform Management System (IPMS) and Combat Management System (CMS), streamlining the operation of its various onboard systems and sensors. These advancements reflect the increasing indigenization of critical defence technologies, a priority for the Indian government.

This submarine also boasts indigenous features that distinguish it from its predecessors. Key upgrades include a domestically developed air conditioning system, internal communication and broadcast systems, and a Ku-band SATCOM (Rukmini) unit. These additions signify a leap in India’s capability to produce high-value components for advanced military applications.

The development of Vaghsheer highlights MDL’s ability to support large-scale projects while modernizing its facilities. The shipyard is now equipped to simultaneously construct up to 10 capital warships and 11 submarines, meeting the growing demands of India’s maritime security strategy.

How Vaghsheer Enhances Submarine Warfare

One of the defining aspects of Vaghsheer is its stealth capability, which is pivotal for successful submarine warfare. Its design minimizes acoustic, optical, electromagnetic, and infrared signatures, making it virtually undetectable in most underwater scenarios. This unique feature allows the submarine to launch precision-guided attacks using torpedoes and anti-ship missiles, either underwater or on the surface.

Additionally, Vaghsheer offers advanced automation features that improve its efficiency and safety during operations. The sophisticated integration of systems ensures optimal performance while reducing the workload on its crew. Its ability to carry out precision strikes and gather critical intelligence data positions it as a transformational asset in submarine warfare.

Expert Insights on India’s Naval Vision

Defence analysts view Vaghsheer’s delivery as a landmark achievement for India’s naval strategy. MDL Chairman and Managing Director Sanjeev Singhal noted that the submarine’s successful delivery reflects MDL’s commitment to self-reliance and technical excellence. Senior naval officials highlighted that the Scorpene-class project represents a turning point for India’s submarine-building capabilities, reinforcing its ability to produce advanced maritime platforms domestically.

The collaborative efforts of MDL, the Indian Navy, and the Department of Defence Production were instrumental in overcoming challenges during the construction and testing phases. These partnerships reflect the government’s emphasis on fostering innovation and collaboration within the defence sector.

The Strategic Role of Vaghsheer

With Vaghsheer joining its predecessors—Kalvari, Khanderi, Karanj, Vela, and Vagir—the Scorpene-class project has significantly bolstered the Indian Navy’s fleet. Each of these submarines has demonstrated unmatched reliability and operational efficiency, providing the Navy with a competitive edge in securing India’s maritime interests.

As maritime conflicts and threats continue to evolve, Vaghsheer’s capabilities will play a pivotal role in enhancing India’s naval deterrence. Its delivery reinforces the Navy’s ability to protect strategic assets, maintain regional stability, and counter emerging security threats.

Future Prospects for India’s Defence Sector

The successful completion of Project P-75 underscores the importance of long-term planning and investment in defence infrastructure. MDL’s modernization initiatives have not only supported the Scorpene-class project but also paved the way for future endeavours. Expansion plans at MDL aim to further enhance its capacity to meet India’s growing maritime needs, ensuring that the shipyard remains a cornerstone of India’s defence strategy.
