Comments

The Indian Navy’s (IN) Anti-Submarine Warfare Shallow Water Craft (ASWSWC) project of 16 hulls will be split evenly between two shipbuilders, Cochin Shipyard Limited (CSL) and Garden Reach Shipbuilders & Engineers (GRSE).

Each shipyard will build its own variant of a 700t waterjet-powered ASW corvette working to common IN-issued specifications. The ASWSWC is intended for coastal ASW missions, minelaying and maritime security operations within 200nm of the coastline.
