INS Malvan is the second vessel of the Mahe-class Anti-Submarine Warfare Shallow Water Craft (ASW-SWC) built for the Indian Navy. The ship was designed and constructed by Cochin Shipyard Limited in Kochi and was delivered to the Navy on 31 March 2026.
Mahe-class Anti-Submarine Warfare Shallow Water Craft
The Mahe-class belongs to the ASW-SWC category, which is meant for operations in shallow coastal waters. These vessels are designed for anti-submarine warfare, mine warfare, and Low Intensity Maritime Operations (LIMO).
Design and Technical Features
INS Malvan is about 80 metres long and has a displacement of 1,100 tonnes. The craft uses waterjets for propulsion and carries advanced sensors, torpedoes, and multifunctional anti-submarine rockets.
Indigenous Shipbuilding in India
INS Malvan has more than 80% indigenous content. The vessel is linked with India’s Aatmanirbhar Bharat framework in naval shipbuilding, which promotes domestic design and construction of warships.
Replacement Role in the Fleet
INS Malvan is intended to replace the Abhay-class corvettes in the Indian Navy. The Abhay-class has served as a smaller anti-submarine platform in coastal and littoral waters.
Important Facts for Exams
- Anti-Submarine Warfare Shallow Water Craft are used in littoral and coastal zones where submarine detection is difficult.
- Waterjet propulsion is commonly used in fast naval craft because it supports manoeuvrability in shallow waters.
- Cochin Shipyard Limited is one of India’s major public sector shipbuilding yards.
- Low Intensity Maritime Operations include patrol, surveillance, and limited combat tasks in coastal areas.
Commissioning Details
The commissioning ceremony of INS Malvan is scheduled for 22 July 2026. Indian Air Force Chief Air Chief Marshal A.P. Singh will preside over the ceremony, and Vice Admiral Sanjay Vatsayan will also attend.
