'Nistar', the first indigenously built Diving Support Vessel was delivered by Hindustan Shipyard Ltd to the Indian Navy on July 8, 2025 at Visakhapatnam.

'Nistar', the first indigenously designed and constructed Diving Support Vessel, was delivered by Hindustan Shipyard Limited to the Indian Navy on July 8, 2025 at Visakhapatnam.

The warship has been designed and built as per classification rules of the Indian Register of Shipping (IRS). The ship is highly specialised and can undertake Deep Sea Diving and Rescue Operations – a capability with select Navies across the globe.

The ship's name, 'Nistar', originates from Sanskrit and means liberation, rescue or salvation. The ship, measuring 118 m with a tonnage of nearly 10,000 tonnes, is installed with state-of-the-art Diving Equipment and has the capability to undertake Deep Sea Saturation Diving up to 300 m depth. The ship also has a Side Diving Stage for undertaking Diving Operations up to 75 m depth.

Measuring 118m & nearly 10,000 tons, Nistar is equipped for Deep Sea Saturation Diving & Rescue Ops up to 300m — a capability held by only a few navies worldwide.

The ship will also serve as the 'Mother Ship' for the Deep Submergence Rescue Vessel (DSRV), to rescue and evacuate personnel, in case of an emergency in a submarine underwater. The ship is equipped with a combination of Remotely Operated Vehicles to undertake Diver Monitoring and Salvage Operations up to a depth of 1000 m.

The delivery of Nistar, with nearly 75 per cent indigenous content, is yet another milestone in the Indian Navy's quest for indigenous construction and is in line with the GoI's vision of Aatmanirbhar Bharat and the Make in India campaign.
