Steel Authority of India Limited (SAIL), a Maharatna Central Public Sector Enterprise under the Ministry of Steel, has played a significant role in the commissioning of INS Taragiri, the fourth ship of the Nilgiri-class (Project 17A) stealth frigates, inducted into the Indian Navy on April 03, 2026.
The warship has been constructed by Mazagon Dock Shipbuilders Limited using the full requirement of approximately 4,000 tonnes of special grade steel plates supplied by SAIL. The specialised steel has been produced at SAIL’s integrated steel plants at Bokaro, Bhilai and Rourkela, demonstrating the company’s advanced metallurgical capabilities and consistent quality standards.
SAIL has been a key contributor to India’s defence indigenisation efforts and continues to support the government’s flagship initiatives of Atmanirbhar Bharat and Make in India. The company had earlier 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.
The successful induction of INS Taragiri marks another milestone in India’s journey towards self-reliance in defence manufacturing and highlights the critical role played by domestic steel producers in strengthening the country’s maritime capabilities.
