Quick Revision: INS Nipun enhances India’s deep-sea diving and submarine rescue capabilities with a 300-metre diving range, aligning with the ‘Atmanirbhar Bharat’ defence manufacturing initiative and strengthening maritime security in the Indian Ocean Region.

Why is this in the news?

The commissioning of INS Nipun, the second Diving Support Vessel (DSV) of the Nistar-class, marks a significant augmentation of India’s deep-sea diving and submarine rescue capabilities. This development is critical amid evolving maritime security dynamics, particularly in the context of contested maritime environments and the need for rapid disaster response in the Indian Ocean Region (IOR). The vessel’s deployment underscores India’s commitment to enhancing operational readiness in submarine rescue, disaster relief, and humanitarian assistance, thereby strengthening its maritime security posture.

Background

• The Indian Navy’s Diving Support Vessel (DSV) programme was initiated to address critical gaps in deep-sea diving, submarine rescue, and disaster relief operations, particularly in the aftermath of the 2008 Mumbai terror attacks and subsequent reviews of India’s maritime security framework.
• The Nistar-class DSVs are part of a broader indigenous shipbuilding initiative under the ‘Make in India’ and ‘Atmanirbhar Bharat’ policies, aimed at reducing reliance on foreign defence platforms and enhancing self-sufficiency in naval capabilities.
• Hindustan Shipyard Limited (HSL), Visakhapatnam, a Defence Public Sector Undertaking (DPSU), was contracted for the construction of these vessels, aligning with the government’s push for indigenous defence manufacturing.
• India’s maritime security strategy has evolved to prioritise rapid response capabilities, including submarine rescue, given the increasing deployment of submarines in the IOR by both regional and extra-regional actors.
• The commissioning of INS Nipun coincides with heightened geopolitical tensions in the West Asian maritime domain, necessitating robust and versatile naval assets to safeguard India’s maritime interests.

What is INS Nipun?

• INS Nipun is a Deep-Sea Diving Support Vessel (DSV) of the Nistar-class, designed to provide advanced diving support, submarine rescue, and disaster relief capabilities to the Indian Navy.
• The vessel was commissioned at the Naval Dockyard, Mumbai, on August 31, 2026, in the presence of the Chief of the Naval Staff, Admiral Krishna Swaminathan, signifying its operational induction into the fleet.
• Constructed by Hindustan Shipyard Limited (HSL), Visakhapatnam, INS Nipun embodies India’s indigenous shipbuilding prowess and aligns with the ‘Atmanirbhar Bharat’ initiative in defence manufacturing.
• The vessel has a length of 119.4 metres and a displacement of 10,500 tonnes, making it one of the largest DSVs in the Indian Navy’s inventory.
• INS Nipun is equipped to support diving operations up to a depth of 300 metres, utilising advanced saturation diving systems and remotely operated vehicles (ROVs) for deep-sea interventions.
• The ship is designed for rapid submarine rescue operations, including the deployment of Deep Submergence Rescue Vessels (DSRVs) and associated diving teams to assist distressed submarines.
• Beyond military applications, INS Nipun is capable of conducting disaster relief and humanitarian operations, including search and rescue missions, medical evacuations, and provision of logistical support during natural calamities at sea.
• The vessel is powered by advanced propulsion systems and incorporates state-of-the-art navigation, communication, and life-support systems to ensure operational reliability in diverse maritime conditions.

UPSC Value Addition

Prelims Practice Questions

Q1. Consider the following statements regarding INS Nipun:
1. INS Nipun is the first Diving Support Vessel (DSV) commissioned by the Indian Navy.
2. It has the capability to support diving operations up to 300 metres depth.
3. The vessel was built by Hindustan Shipyard Limited.
