On 15 January 2025, INS Surat, INS Nilgiri, and INS Vaghsheer were commissioned together at the Naval Dockyard in Mumbai. INS Surat is the fourth and final ship of the Project 15B guided-missile destroyer class. INS Nilgiri is the first ship of the Project 17A stealth-frigate class. INS Vaghsheer is the sixth and final submarine of Project 75, the Scorpene-class submarine programme. The commissioning of a destroyer, frigate, and submarine on one day highlighted indigenous shipbuilding and fleet modernisation. Commissioning adds capability, but readiness also depends on crews, maintenance, logistics, training, and operational integration.
