INS Samarthak Joins Navy to Support Weapons Trials and Maritime Operations

Summary

The Indian Navy commissioned INS Samarthak on 16 October 2026, adding an indigenously designed multi-purpose platform for weapons and sensor trials, surveillance and other maritime missions. Built by Larsen & Toubro, the vessel contains more than 75% indigenous content and strengthens private-sector participation in naval shipbuilding.

Commissioning expands testing capabilities.

INS Samarthak entered naval service at Karwar, Karnataka, marking the operational induction of the first vessel of its class. Vice-President C. P. Radhakrishnan presided over the ceremony, attended by Chief of the Naval Staff Admiral Krishna Swaminathan and representatives of the defence industry.

The ship’s principal contribution is its ability to support trials and evaluation of domestically developed weapons and sensors. Its adaptable design also allows deployment for maritime surveillance, reconnaissance, offshore patrols and humanitarian assistance and disaster relief.

The commissioning brings together two priorities for the Navy: developing indigenous technology and acquiring platforms capable of undertaking several supporting missions.

A platform for technology development

Samarthak’s planned functions extend beyond conventional patrol duties. Earlier project announcements identified capabilities including towing ships, launching and recovering targets, operating uncrewed autonomous vehicles and supporting trials of indigenous equipment.

These activities provide a maritime environment in which emerging systems can be evaluated. For developers, testing equipment at sea is an important stage between design work and its integration into operational platforms.

The ship’s combination of trial-support and operational roles gives the Navy flexibility in assigning tasks. Its induction, however, should be distinguished from the successful qualification of any particular weapon or sensor; individual systems remain subject to their respective development and evaluation programmes.

L&T has also identified environmental protection among the vessel’s supporting functions. A dynamic positioning system provides precision control during complex manoeuvres, complementing the ship’s role as a specialised test and trials platform.

Indigenous design and construction

Samarthak was developed through L&T’s in-house Warship Design Centre and constructed at its Kattupalli Shipyard near Chennai.

More than three-quarters of the vessel’s content is indigenous. Construction incorporated modular methods and pre-outfitting, allowing equipment and systems to be integrated into sections during the build process.

The project therefore represents more than the assembly of a completed hull. It combines domestic design, engineering, equipment integration and shipyard execution—capabilities relevant to the development of a broader naval manufacturing base.

In its published specifications, L&T describes the multi-purpose vessels as approximately 107 metres long and 18.6 metres wide, with displacement exceeding 3,750 tonnes. The design accommodates the range of trial-support, maritime and emergency-response functions envisaged for the class.

From construction contract to naval service

The Ministry of Defence signed the original contract with L&T for two multi-purpose vessels on 25 March 2022.

Samarthak was launched at Kattupalli on 14 October 2024. Launching placed the vessel afloat for the subsequent stages of completion and testing; it was a separate milestone from delivery and commissioning.

The Navy formally received the vessel on 27 August 2026. Its commissioning on 16 October followed that handover, completing the transition from shipyard delivery to induction into naval service.

The second vessel, Utkarsh, was launched in January 2025, around three months after Samarthak. That earlier announcement demonstrated parallel progress within the original two-ship programme, although launch alone did not establish its delivery or operational status.

Private shipbuilding gains a further reference project

For India’s shipbuilding industry, Samarthak provides a completed example of a private yard undertaking a specialised naval platform from design through construction and delivery.

At the time of its September 2026 delivery announcement, L&T said Kattupalli was also constructing the second multi-purpose vessel and three cadet training ships for the Navy. This places Samarthak within a continuing naval construction programme rather than an isolated assignment.

The industrial significance lies in the experience accumulated across engineering, production planning, supplier coordination and systems integration. Such experience can support future work, although subsequent orders will depend on procurement decisions and demonstrated performance.

For the Navy, the immediate outcome is an additional platform that can support technology development while remaining available for other assigned maritime duties. Its practical contribution will emerge through the testing programmes, training activities and operational missions undertaken after commissioning.
