INS Malvan 2026: Mahe-Class ASW Craft to Be Commissioned into Indian Navy
By Vikas Sir, Founder & Senior Faculty – Cosmo Classes | 17 July 2026
The Indian Navy is set to strengthen its coastal defence capabilities with the commissioning of INS Malvan, scheduled for 22 July 2026. INS Malvan is the second vessel of the Mahe-class Anti-Submarine Warfare Shallow Water Craft (ASW-SWC), a new generation of warships designed specifically for operations close to the Indian coastline. This development is an important defence current-affairs topic for UPSC, RPSC, SSC, CDS, NDA and State PSC examinations.
INS Malvan was designed and constructed by Cochin Shipyard Limited (CSL) in Kochi, one of India's premier public-sector shipbuilding yards, and was formally delivered to the Navy on 31 March 2026. The Mahe-class belongs to the ASW-SWC category, which is purpose-built for anti-submarine warfare, mine warfare and Low Intensity Maritime Operations (LIMO) in shallow coastal and littoral waters where detecting enemy submarines is particularly challenging.
In terms of design, INS Malvan is approximately 80 metres long with a displacement of about 1,100 tonnes. A notable engineering feature is its waterjet propulsion system, which gives the craft excellent manoeuvrability and allows it to operate effectively in shallow waters. The vessel is equipped with advanced sensors, torpedoes and multifunctional anti-submarine rockets, making it a potent platform for tracking and neutralising underwater threats near the coast.
One of the most significant aspects of INS Malvan is its indigenous content of more than 80%. The vessel is a strong example of the Aatmanirbhar Bharat (self-reliant India) initiative in the field of naval shipbuilding, which promotes the domestic design and construction of warships. This not only reduces India's dependence on foreign defence imports but also strengthens the country's indigenous defence manufacturing ecosystem and generates skilled employment.
In the fleet, INS Malvan is intended to replace the ageing Abhay-class corvettes, which have long served as smaller anti-submarine platforms in India's coastal and littoral zones. The induction of modern Mahe-class craft ensures that the Navy maintains a technological edge in shallow-water anti-submarine operations, an area of growing strategic importance given the increasing presence of foreign submarines in the Indian Ocean Region.
The commissioning ceremony on 22 July 2026 will be presided over by the Chief of the Air Staff, Air Chief Marshal A.P. Singh, with Vice Admiral Sanjay Vatsayan also in attendance. The event underlines the growing inter-service coordination in India's armed forces and highlights the nation's steady progress towards a self-reliant, technologically advanced blue-water and coastal navy.
