🛳 A Bold Step Beneath the Surface
On July 18, 2025, a proud chapter in Indian maritime history was written at Visakhapatnam when INS Nistar, the country’s first indigenously designed and built Diving Support Vessel (DSV), was commissioned into the Indian Navy. The event, graced by Raksha Rajya Mantri Shri Sanjay Seth, was not just a ceremony—it was a celebration of India’s growing strength and self-reliance in defence and technology.
🎯 What Is a Diving Support Vessel?
For aspirants preparing for defence or technical exams, understanding INS Nistar’s purpose is essential:
- A Diving Support Vessel (DSV) is a special type of naval ship designed to support underwater operations.
- It helps with deep sea saturation diving, rescue missions, and submarine salvage efforts.
- With high-end equipment, it can dive up to 300 meters below sea level and rescue crew trapped in sunken submarines.
Now imagine—just a handful of navies in the world possess this capability. And India has proudly joined that elite list with a vessel made on its own soil!
🧠 Behind the Scenes: Built in India, Designed for the Future
INS Nistar was constructed by Hindustan Shipyard Limited (HSL), based in Vizag. It is the first of two DSVs planned, and a landmark project under the Aatmanirbhar Bharat mission. Here’s why it stands out:
| Feature | Details |
|---|---|
| Length | 118 meters |
| Displacement | 10,000+ tons |
| Indigenous Content | 80% |
| MSME Participation | 120+ Indian MSMEs |
| Depth Capability | Up to 300 meters |
| Major Equipment | ROVs, Hyperbaric Life Boat, Diving Compression Chambers |
The ship also plays the role of a ‘Mother Ship’, supporting Deep Submergence Rescue Vessels (DSRVs) used to evacuate trapped submarine personnel during emergencies.
