In a boost to India’s maritime capabilities and self-reliance in defence production, the Indian Navy will today commission its first indigenously designed and built Diving Support Vessel (DSV) Nistar at the Naval Dockyard in Visakhapatnam. Defence Minister Rajnath Singh will preside over the commissioning ceremony, marking the formal induction of the state-of-the-art vessel into the Eastern Naval Command.
Designed and constructed by Hindustan Shipyard Limited (HSL), Visakhapatnam, Nistar represents a major milestone in the nation’s pursuit of Aatmanirbharta (self-reliance) in defence manufacturing. More than 120 Micro, Small, and Medium Enterprises (MSMEs) contributed to the construction of the vessel, helping achieve an impressive indigenous content of over 80 percent.
With a length of approximately 120 meters and a displacement exceeding 10,000 tons, Nistar is equipped with cutting-edge technology to support deep-sea diving and submarine rescue missions. It features a Dynamic Positioning System for precise maneuverability, advanced Air and Saturation Diving Systems, underwater Remotely Operated Vehicles (ROVs), and Side Scan SONAR systems.
Significantly, Nistar will serve as the ‘Mother Ship’ for the Deep Submergence Rescue Vehicle (DSRV), marking a major enhancement in India’s submarine rescue capabilities.
Onboard medical facilities further strengthen the ship’s versatility, with an operation theatre, intensive care unit, eight-bedded hospital, and hyperbaric medical infrastructure designed to support critical rescue and diving operations. The vessel also boasts an endurance of over 60 days at sea, helicopter staging capability, and a 15-ton subsea crane.
The new vessel carries forward the legacy of its predecessor – ex-Nistar, a submarine rescue vessel acquired from the erstwhile USSR in 1969, which served the Navy until the early 1990s. The new Nistar inherits her motto: Surakshita Yatharthta Shauryam – “Deliverance with Precision and Bravery.”
