The Torpedo Advanced Light (TAL) Shyena is the first indigenous advanced lightweight anti-submarine torpedo of India, developed by the Naval Science and Technological Laboratory (NSTL) of the Defence Research and Development Organisation (DRDO) for the Indian Navy. The lightweight torpedo can be launched by ships, helicopters and previously the now retired Ilyushin Il-38, named after the divine hawk identified with Agni.
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 Abhay-class corvettes 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).
The Indian Navy has been focusing on developing indigenous platforms, systems, sensors and weapons as part of the nation's modernisation and expansion of its maritime forces.
