Hindustan Shipyard Limited has handed over INS Nipun, the second indigenously built Diving Support Vessel, to the Indian Navy at Visakhapatnam, a moment that meaningfully strengthens India’s deep-sea rescue and underwater operational capacity. Stretching 118 metres and built with over 80 percent indigenous content, the vessel comes equipped with advanced systems for saturation diving, submarine rescue, and deep-sea intervention, all of which feed into India’s broader push for maritime self-reliance.
The handover took place on July 30, 2026, exactly one year after HSL delivered INS Nistar, the first ship in this class. The timing itself says something about HSL’s growing standing when it comes to building complex strategic platforms, and about its role in pushing indigenous defence manufacturing forward under the Aatmanirbhar Bharat programme.
Signing Off on the Acceptance Document
Rear Admiral Arvind Rawal, Chief Staff Officer (Tech) at Western Naval Command and Chairman of the D448 Committee, signed the acceptance document alongside Rear Admiral Chandrasekharan Raghuram (Retd.), Chairman and Managing Director of HSL.
Specifications and Onboard Systems
INS Nipun runs 118 metres in length and displaces more than 8,560 tonnes. It’s built with advanced dynamic positioning systems, saturation diving equipment, submarine rescue machinery, and deep-sea intervention tools, all packed into one vessel.
Together, these systems give the Navy an integrated, capable platform for handling complex underwater work, including submarine rescue operations and salvage missions. INS Nipun also doubles as the Mother Ship for the Navy’s Deep Submergence Rescue Vessel, meaning it can support rapid evacuation and rescue of personnel if a submarine emergency ever arises.
A Name That Reflects Its Purpose
The name Nipun comes from Sanskrit, roughly translating to “adept” or “capable,” fitting for a vessel purpose-built for deep-sea diving and rescue work. It carries Remotely Operated Vehicles (ROVs) on board, which extend its operational reach by supporting diver monitoring, underwater inspection, and salvage tasks.
Its saturation diving systems let divers work at considerable depths for long stretches at a time, a capability that’s become essential to modern naval operations.
A Symbol of Collaboration and Self-Reliance
INS Nipun’s delivery reflects the coordinated effort between the Union Government, the Indian Navy, and public sector shipyards in expanding India’s own maritime capabilities. Industry voices have pointed to the vessel’s commissioning as proof of India’s commitment to self-reliant defence shipbuilding, one that also sharpens the country’s operational readiness at sea.
With more than 80 percent of its content built domestically, INS Nipun stands as a showcase for India’s defence industrial base, blending advanced technology with manufacturing done at home.
What This Means for the Navy’s Capabilities
Bringing INS Nipun into service is expected to considerably strengthen the Navy’s abilities in underwater inspection, salvage assistance, submarine rescue, and coastal operational deployment.
Paired with INS Nistar, INS Nipun completes the set of two Diving Support Vessels the Indian Navy had ordered, rounding out the fleet’s specialised underwater support infrastructure. This also strengthens India’s capacity to sustain extended naval deployments and respond effectively when emergencies happen at sea.
More Than a Technological Milestone
The commissioning of this vessel is as much a strategic step as it is a technological one. It reflects the Navy’s readiness to take on complex underwater missions and underscores how indigenous shipbuilding continues to support India’s national security goals. With INS Nipun now delivered, HSL has further cemented its place as a key player in India’s defence shipbuilding programme.
Key Takeaway: The induction of INS Nipun significantly enhances the Indian Navy’s specialised underwater operational capabilities by strengthening its capacity for submarine rescue, deep-sea diving, salvage operations, and underwater intervention. Built with over 80 percent indigenous content by Hindustan Shipyard Limited, the vessel reflects India’s growing self-reliance in defence shipbuilding and complements INS Nistar in establishing a dedicated Diving Support Vessel capability.
Equipped with advanced saturation diving systems, dynamic positioning technology, Remotely Operated Vehicles, and Deep Submergence Rescue Vessel support, INS Nipun reinforces India’s maritime preparedness, operational readiness, and broader efforts to modernise its naval capabilities under the Aatmanirbhar Bharat initiative.
