What is INS Mangrol?

INS Mangrol is an Anti-Submarine Warfare Shallow Water Craft (ASW-SWC) indigenously designed and built by Cochin Shipyard Limited for the Indian Navy. These vessels are specialised for detecting and neutralising submarines in shallow coastal waters, a critical role in India’s maritime defence strategy. The ship is named after the coastal township of Mangrol in Gujarat, following the tradition of naming naval vessels after coastal cities.

INS Mangrol is equipped with modern systems including lightweight torpedoes, indigenous ASW rockets, and advanced shallow-water sonars. The vessel is part of a class of eight such craft being constructed under the ‘Make in India’ initiative, highlighting the navy’s commitment to indigenous shipbuilding.

Why is INS Mangrol in News?

INS Mangrol has been in the news because it is the third vessel of its class to be delivered, following the delivery of the first two vessels earlier. This delivery is a milestone in the Indian Navy’s modernisation plan, enhancing its anti-submarine warfare capabilities in the littoral waters. The induction of these vessels is part of the navy’s larger strategy to counter submarine threats in the Indian Ocean region, where China and Pakistan have been expanding their underwater fleet.

The vessel’s indigenous design and construction also underscore India’s progress in self-reliance in defence manufacturing. The delivery of INS Mangrol is a testament to the capabilities of Indian shipyards. For official updates, refer to the PIB release on the delivery.

Key Features of INS Mangrol

• Shallow Water Operations: Designed for coastal waters, capable of detecting and neutralising submarines in shallow depths.
• Indigenous Sonar: Equipped with advanced shallow-water sonar systems for effective underwater surveillance.
• Weapons Suite: Carries lightweight torpedoes and indigenous ASW rockets for anti-submarine warfare.
• Indigenously Built: Constructed at Cochin Shipyard Limited, showcasing India’s shipbuilding capabilities.
• Strategic Naming: Named after Mangrol, a coastal town in Gujarat, reflecting regional ties.

Challenges in Maritime Security

• Submarine Proliferation: Increasing number of submarines in the region, particularly from China and Pakistan, poses a significant threat.
• Underwater Surveillance: Detecting modern quiet submarines requires advanced sensor technology.
• Indigenous Production: Ensuring timely delivery and quality of indigenously built warships remains a challenge.
• Coastal Security: Protecting India’s vast coastline from asymmetric threats like terror attacks via sea routes.

Way Forward for Naval Modernisation

The induction of INS Mangrol is a step forward, but India needs to accelerate its naval expansion to maintain a credible deterrence. The government’s focus on ‘Make in India’ should be complemented with technology transfer and joint ventures with global players to bring in cutting-edge capabilities. Strengthening underwater surveillance networks and investing in unmanned underwater vehicles are also crucial.

As per the Indian Navy‘s long-term plan, the service aims to have over 200 ships by 2030. Achieving this will require sustained funding, streamlined procurement, and a robust domestic shipbuilding industry.
