New Delhi: Malwan ASW SWC was delivered to the Indian Navy by Cochin Shipyard Limited (CSL) on 31 March 2026, marking a major milestone in India’s indigenous defence manufacturing journey. This is the second of eight Anti-Submarine Warfare Shallow Water Craft being built under a strategic naval program.
The delivery strengthens India’s coastal security and highlights the country’s growing focus on self-reliance under the Aatmanirbhar Bharat initiative.
What is Malwan ASW SWC
Malwan is part of a new class of advanced warships specially designed for anti-submarine warfare in shallow coastal waters.
These vessels are compact but powerful, built to detect and neutralize underwater threats near India’s coastline.
- Built by: Cochin Shipyard Limited (CSL), Kochi
- Type: Anti-Submarine Warfare Shallow Water Craft (ASW SWC)
- Role: Detect, track and destroy enemy submarines
- Status: Second vessel in a planned series of eight
The project was approved by the Ministry of Defence to replace older Abhay-class corvettes and modernize India’s naval fleet.
What are the Features of Malwan ASW SWC
Malwan is equipped with advanced technology to operate effectively in shallow waters:
- Length: Around 80 meters
- Displacement: ~1,100 tonnes
- Propulsion: Waterjet system for high agility
- Weapons: Torpedoes and anti-submarine rockets
- Sensors: Advanced sonar systems and radars
- Operations: Anti-submarine warfare, mine warfare, and surveillance
These ships are designed to operate in littoral zones (coastal areas) where traditional large warships cannot perform efficiently.
Indigenous Power: Made in India
One of the biggest highlights of Malwan is its over 80% indigenous content, making it a strong example of India’s defence self-reliance.
- Built using Indian technology and systems
- Involvement of MSMEs and domestic defence companies
- Supports the Aatmanirbhar Bharat initiative
This reflects India’s growing capability in designing and building complex warships domestically.
What is the Importance of Malwan ASW SWC
The induction of Malwan significantly enhances India’s maritime security:
1. Strong Coastal Defence
These vessels act as the first line of defence against submarine threats near Indian shores.
2. Better Underwater Surveillance
Advanced sonar and sensors improve tracking of enemy submarines.
3. Multi-role Capability
Apart from anti-submarine warfare, Malwan can perform:
- Mine laying
- Low-intensity maritime operations
- Coastal patrol missions
4. Future Warfare Ready
Modern naval conflicts are becoming multi-domain, and such vessels ensure India stays prepared.
Part of a Larger Naval Program
Malwan is the second ship after INS Mahe, which was delivered in October 2025.
The full series includes 8 vessels:
- Mahe
- Malwan
- Mangrol
- Malpe
- Mulki
- Munroe
- Makkah
