Visakhapatnam-class (P-15 Bravo)

The Visakhapatnam class, designated Project 15B, is a series of stealth guided-missile destroyers operated by the Indian Navy. Designed by the Warship Design Bureau, the class is a derivative of the preceding Kolkata class. The Defence Acquisition Council approved the procurement of four vessels in March 2009 to be built by Mazagon Dock Shipbuilders Limited. The design was finalized in 2013, utilizing the baseline of the Project 15A design with incremental alterations to minimize developmental costs and timelines.

The design incorporates a modified bridge layout intended to reduce the vessel's radar cross-section. Technical features include a network-centric layout equipped with a Ship Data Network, an Automatic Power Management System, and a Combat Management System. For aviation support, the class utilizes a rail-less traversing system to secure helicopters in adverse weather conditions. Survivability measures include multiple fire zones, battle damage control systems, and distributional power systems. The vessels are equipped with a Total Atmosphere Control System and filtration equipment for operations in nuclear, biological, and chemical warfare environments. Indigenous content accounts for approximately 72% of the platform.

The lead ship, INS Visakhapatnam, was commissioned in November 2021. Following its induction, the vessel conducted test firings of the BrahMos anti-ship missile in early 2022 and participated in the Presidential Fleet Review in February 2022. The second vessel, INS Mormugao, entered service in December 2022. In May 2023, it carried out missile engagement trials against sea-skimming supersonic targets. The third ship, INS Imphal, was commissioned in December 2023, followed by the final vessel of the class, INS Surat, in January 2025. All four units are currently in active service with the Indian Navy.
