About Mahe- Anti-Submarine Warfare Shallow Water Craft
The Indian Navy received the Mahe Anti-Submarine Warfare Shallow Water Craft (ASW SWC) on October 23, 2025. Built by Cochin Shipyard Limited (CSL), it is the first of eight such vessels being constructed by CSL as a replacement for the aging Abhay-class corvettes. 
Key features

• Design and construction: The Mahe was indigenously designed and built in India, reflecting the government's "Aatmanirbhar Bharat" (self-reliant India) initiative. It was constructed under the supervision of the classification society Det Norske Veritas (DNV).
• Capabilities: The corvette is engineered to conduct a range of coastal defense and warfare tasks, including:
  • Anti-Submarine Warfare (ASW) and detection of underwater threats in coastal waters.
  • Underwater surveillance.
  • Mine-laying operations.
  • Low-Intensity Maritime Operations (LIMO).
  • Search and rescue operations.

• Armament and sensors: The Mahe is equipped with:         
  • Torpedoes.
  • Multi-functional anti-submarine rockets.
  • Advanced radar and sonar systems for threat detection.

• Technical specifications:
  • Length: 78 meters.
  • Displacement: Around 1,100 tons.
  • Propulsion: A diesel engine-waterjet combination, making it the largest Indian naval vessel to use this system.
  • Indigenous content: More than 80% of the vessel's components are indigenous. 

The ASW SWC project
The Mahe is part of a larger, 16-ship ASW SWC program for the Indian Navy. The contract was signed with Cochin Shipyard and Garden Reach Shipbuilders & Engineers (GRSE) in 2019, with each company building eight ships. 
The induction of these crafts will substantially boost the Indian Navy's capabilities in shallow water anti-submarine warfare, enhancing India's maritime security in its littoral zones.
