Diving Support Craft are unglamorous but necessary. They provide the platform from which naval divers carry out underwater inspection of hulls and harbour installations, search for and recover objects from the seabed, and conduct salvage and rescue work. Completing a five-ship class means the capability is available across naval commands rather than concentrated at one station. The builder is the more notable detail: Titagarh Rail Systems is best known as a rolling stock manufacturer, and its shipbuilding arm taking on a full naval class illustrates how defence orders have been distributed beyond the traditional public sector shipyards under the indigenisation push.
