The Indian Navy has officially taken delivery of Nistar, the country’s first indigenously designed and constructed Diving Support Vessel (DSV). The vessel was handed over by Hindustan Shipyard Limited on July 8, 2025, at Visakhapatnam, marking a major stride towards India’s maritime self-reliance.
Nistar has been meticulously built under the classification rules of the Indian Register of Shipping (IRS), ensuring high standards of design and safety. This specialized warship is equipped to undertake complex Deep Sea Diving and Rescue Operations, a niche capability held by only a few navies worldwide.
The name “Nistar” is derived from Sanskrit and translates to liberation, rescue, or salvation — perfectly echoing the vessel’s primary purpose. Measuring 118 meters in length and weighing approximately 10,000 tons, the vessel integrates cutting-edge technologies for underwater missions.
Among its notable features, Nistar can perform Saturation Diving up to 300 meters deep and utilize a Side Diving Stage for operations up to 75 meters. Additionally, the vessel has been designed to act as the ‘Mother Ship’ for the Deep Submergence Rescue Vessel (DSRV), making it indispensable during submarine rescue scenarios.
To enhance rescue and salvage operations, the ship comes equipped with advanced Remotely Operated Vehicles (ROVs) capable of operating at depths of up to 1000 meters. These technologies are crucial for diver monitoring, deep-sea recovery, and emergency evacuations.
The successful delivery of Nistar with nearly 75% indigenous components not only demonstrates the technological capabilities of Indian shipyards but also aligns perfectly with the Government of India’s ambitious Aatmanirbhar Bharat and Make in India initiatives. It reaffirms India’s commitment to strengthening its naval infrastructure with homegrown innovation and resilience.
Why Nistar is a Game Changer for India
The induction of Nistar significantly enhances the Indian Navy’s capability in underwater operations, strategic support, and disaster response. It closes a critical capability gap and positions India alongside elite maritime forces with specialized deep-sea support assets.
