The Indian Navy commissioned INS Nistar, a diving support vessel (DSV), India first indigenously constructed, in Visakhapatnam. The 118-metre ship is built by Hindustan Shipyard Ltd. and is fitted to work with deep-sea saturation diving and submarine rescue. The ship enhances the ability of India to serve as a regional maritime security partner and the Aatmanirbhar Bharat initiative. Possessing ROVs, hyperbaric lifeboats, and compression rooms, it is capable of working in a depth of up to 300 metres. The INS Nistar will serve as a mother to Deep Submergence Rescue Vessels (DSRVs) that are applied in cases of submarine disaster.<\/p>\n
