The Steel Authority of India Limited (SAIL), a Maharatna central public sector enterprise under the Ministry of Steel, played a significant role in the commissioning of INS Taragiri, the fourth ship of the Nilgiri-class, Project 17A stealth frigates, which was inducted into the Indian Navy on April third, 2026. The contribution formed part of a coordinated defence manufacturing effort to enhance indigenous maritime capability. The induction is expected to bolster operational readiness of the navy in the relevant maritime theatre. Mazagon Dock Shipbuilders Limited constructed the warship using the full requirement of approximately 4,000 tonnes (t) of special grade steel plates supplied by SAIL, with the specialised steel produced at SAIL's integrated steel plants at Bokaro, Bhilai and Rourkela. The supply chain and production processes were presented as evidence of the company’s advanced metallurgical capabilities and consistent quality standards. The coordination between shipbuilder and supplier demonstrated logistical planning and quality assurance measures during production and delivery. SAIL has been identified as a key contributor to India’s defence indigenisation initiatives and continues to support the Government’s flagship programmes of Atmanirbhar Bharat and Make in India through material and technical inputs. The company previously supplied special steel for several critical naval platforms, including the indigenous aircraft carrier INS Vikrant and the first three ships of the Project 17A class, INS Nilgiri, INS Himgiri and INS Udaygiri, reinforcing a track record of collaboration with naval shipbuilding agencies. This pattern of supply has supported major naval construction programmes over recent years. The successful induction of INS Taragiri was described as another milestone in the journey towards self-reliance in defence manufacturing and underlined the critical role played by domestic steel producers in strengthening the country’s maritime capabilities. Future shipbuilding programmes are expected to continue drawing on domestic specialised steel production to meet strategic requirements. Continued reliance on domestic supply chains is likely to reduce dependence on imports and support strategic autonomy.
