INS Mangrol: Indigenous Anti-Submarine Warfare Vessel
The Indian Navy is scheduled to commission INS Mangrol on 12 October 2026 at the Naval Dockyard in Mumbai, strengthening India’s coastal anti-submarine warfare capabilities. Vice Admiral Sanjay Vatsayan, Flag Officer Commanding-in-Chief of the Western Naval Command, is scheduled to preside over the ceremony. Built by Cochin Shipyard Limited (CSL), INS Mangrol is an Indigenous Anti-Submarine Warfare Shallow Water Craft (ASW-SWC) featuring more than 80% indigenous content. The vessel reflects India’s efforts to enhance maritime security and promote self-reliance in defence manufacturing.
Anti-Submarine Warfare in Shallow Waters
Anti-submarine warfare (ASW) involves operations to detect, track and counter hostile submarines. Shallow-water ASW focuses on coastal and littoral zones, including approaches to ports, harbours and other strategically important maritime areas.
INS Mangrol is designed to operate in these waters and respond to submarine threats. Its major systems include:
- Abhay hull-mounted sonar: Helps detect and track underwater targets.
- Lightweight torpedoes: Provide an offensive capability against submarines.
- Indigenous anti-submarine rocket launcher: Supports underwater threat engagement.
- Mareech Advanced Torpedo Decoy System: Designed to divert incoming torpedoes away from the vessel.
Together, these systems enhance the vessel’s underwater detection, threat-response and defensive capabilities.
Indigenous Shipbuilding and ASW-SWC Project
INS Mangrol is part of a programme to construct 16 Anti-Submarine Warfare Shallow Water Craft for the Indian Navy. The construction work is divided equally between two Indian shipyards:
- Cochin Shipyard Limited (CSL): Eight vessels.
- Garden Reach Shipbuilders & Engineers (GRSE): Eight vessels.
INS Mangrol is identified as the third ASW-SWC and the seventh vessel commissioned under the overall project. With indigenous content exceeding 80%, the vessel contributes to the development of domestic shipbuilding capabilities, defence manufacturing and technological self-reliance.
Why Is INS Mangrol Significant?
India’s extensive coastline and maritime trade routes make coastal security an important component of national defence. Shallow-water naval vessels can operate in areas where larger warships may face operational constraints. Vessels such as INS Mangrol can strengthen surveillance and anti-submarine operations near ports, coastal installations and important sea approaches.
The vessel also continues a naval naming legacy. It is named after Mangrol, a coastal town in Gujarat’s Junagadh district. An earlier vessel, INS Mangrol (M85), served the Indian Navy as a minesweeper until 7 April 2004. Minesweepers are naval vessels designed to detect and clear naval mines.
