The Anti-Submarine Warfare Shallow Water Craft (ASW-SWC) corvettes, are a class of anti-submarine warfare (ASW) vessels currently being built for the Indian Navy, by Cochin Shipyard (CSL) and Garden Reach Shipbuilders & Engineers (GRSE). They were conceived as a replacement to the ageing s of the Indian Navy, and are designed to undertake ASW duties – including subsurface surveillance in littoral waters, search-and-attack unit (SAU) missions and coordinated anti-submarine warfare operations with naval aircraft. They were also designed to provide secondary duties – including defense against intruding aircraft, minelaying and search-and-rescue (SAR).
