Project 15B Class Destroyer
The contract for four ships of the Visakhapatnam class was inked in January 2011. Project 15B is a follow-on project of the Kolkata class destroyers that were commissioned in the last decade. The Visakhapatnam class of warships was designed by the Indian Navy's in-house design organisation Directorate of Naval Design and costructed by the Mazagon Dock Shipbuilders Limited.
The Visakhapatnam class warships, which can accommodate a crew of 312 persons, have been named after major cities -- Visakhapatnam, Mormugao, Imphal and Surat. In October 2013, the keel of the first warship, Visakhapatnam was laid and the ship was launched in April 2015. According to naval officials, the design draws heavily from the platform equipment, hull form, weapons systems and sensors and propulsion machinery of the Kolkata class warships.
Visakhapatnam, which has an endurance of 4000 nautical miles and can be on a 42-day missions, is equipped with supersonic surface-to-surface BrahMos missiles and the Barak-8 long-range surface-to-air missiles. Two onboard helicopters will extend the ship's reach. It will also have incredible undersea warfare capability and will be armed with indigenously developed anti-submarine weapons, heavyweight torpedo launchers, hull-mounted sonar Humsa NG and rocket launchers.
The second ship of P15B series, Mormugao is undergoing preparations for harbour trials. The third ship, Imphal is at an advance stage of outfitting while the fourth ship will be launched within this year.
