All four Project 15B destroyers are commissioned, with final ship INS Surat participating in operational exercises during July 2026.
On 8 July 2026, INS Surat, the fourth and final Project 15B destroyer, exercised with Japan's JS Takanami in the Arabian Sea, underscoring that the class is fully delivered and operationally active. All four ships—Visakhapatnam, Mormugao, Imphal and Surat—were commissioned between November 2021 and January 2025. These 7,400–7,500-tonne ships combine BrahMos strike weapons, Barak-8 area air defence and modern sensors in Indian-built hulls. For India, the class strengthens carrier escort, sea-control and long-range strike capacity across the Arabian Sea, Bay of Bengal and wider Indo-Pacific.
