SAIL Supplied Critical-Grade Steel for INS Udaygiri, INS Himgiri

New Delhi, August 26, 2025: Steel Authority of India Limited (SAIL) continues its crucial partnership with the defence sector by supplying approximately 8,000 tonnes of critical-grade steel for the Navy’s advanced frontline frigates INS Udaygiri and INS Himgiri. During a ceremony presided over by the defence minister Rajnath Singh, the two frigates were commissioned in Visakhapatnam on Tuesday.
 
SAIL played a crucial role in building the two advanced frigates. Partnering with Mazagon Dock Shipbuilders Limited and Garden Reach Shipbuilders & Engineers Limited, SAIL supplied essential critical-grade hot-rolled sheets and plates from its Bokaro, Bhilai and Rourkela plants.

By developing and providing critical-grade steel, SAIL has made a significant contribution to import substitution and defence self-reliance, directly supporting the Atmanirbhar Bharat and Make in India initiatives and decreasing India’s dependence on imported special quality steel for defence requirements.

Special Plate Plant at RSP alone has supplied over 100,000 tonnes of critical-grade steel for defence applications like tanks, warships and missiles.

The commissioning of INS Udaygiri and INS Himgiri demonstrates the strength and depth of a fully indigenous defence ecosystem—from the foundational steel to the intricate design and dedicated crew.

SAIL’s enduring partnership with the defence sector is well-established with a proud history of supplying critical-grade steel for iconic vessels such as the INS Vikrant, INS Nilgiri, INS Ajay, INS Nistar, INS Arnala, INS Vindhyagiri and INS Surat, among others. This unwavering commitment solidifies SAIL’s standing as a trusted national manufacturer and a vital collaborator in the country’s ongoing naval modernisation.
