The steel supplied by SAIL includes special quality DMR 249A grade hot-rolled sheets and plates. This specialized, defense-grade steel was meticulously manufactured and supplied from SAIL’s flagship facilities at Bokaro, Bhilai, and Rourkela Steel Plants, underscoring the Maharatna’s robust technological capability in supporting India’s maritime defense infrastructure.

SAIL continues to propel the nation’s Atmanirbhar Bharat and Make in India initiatives. By producing specialized steel for critical naval platforms, SAIL has become integral part to India’s defense indigenisation. To meet the emerging requirements of the defense sector, SAIL has taken extra measures well in advance to enhance the production of DMR Grade plates for defense requirements at its Plate-production facilities, specifically at the Special Plate Plant in the Rourkela Steel Plant. This strategic move is clearly reflected in India’s growing import substitution in the field of defense-grade steel. Its stellar track record includes provisioning the landmark indigenous aircraft carrier INS Vikrant, alongside the elite Project 17A stealth frigates-INS Nilgiri, INS Himgiri, and INS Udaygiri. Furthermore, SAIL’s specialized steel forms the backbone of formidable vessels like INS Ajay, INS Nistar, and INS Anjadeep among others. The successful induction of these advanced warships marks a defining milestone in India’s maritime capabilities and sovereignty.

SAIL CMD Dr. Ashok Kumar Panda said, “As a key partner in India’s defense sector, SAIL remains deeply committed to national self-reliance. To stay ahead in the defense sector’s growing needs, the company boosted its manufacturing capacity for DMR Grade plates -focusing heavily on the Special Plate Plant at the Rourkela Steel Plant. Delivering these high-strength DMR 249A steel plates protects India’s strategic independence while highlighting SAIL’s cutting-edge technical expertise.”

This ship is part of a larger government plan to build 11 advanced patrol vessels at shipyards in Goa and Kolkata to protect India’s waters. Once ready, Sanghmitra will be used for important missions like stopping sea pirates, monitoring coastlines, protecting offshore oil rigs, and helping with search and rescue operations during natural disasters. Defense officials highlighted that building this ship locally is a major success for India’s “Make in India” goals, proving that the nation is becoming completely self-reliant in manufacturing its own powerful military hardware.
