    About INS Visakhapatnam

    • It is designed at the Directorate of Naval Design, the Indian Navy’s in-house organisation, and built by the state-owned Mazagon Dock Shipbuilders Limited, Mumbai.
    • It is the first of the stealth guided-missile destroyers being indigenously constructed under Project 15B.
    • The warship is equipped to fight under Nuclear, Biological and Chemical (NBC) warfare conditions.
    • The ship is propelled by a powerful combined gas and gas (COGAG) propulsion plant, consisting of four reversible gas turbines, which enables it to achieve a speed of over 30 knots or approximately 55 km/hr.
    • Capability :
      • It is “one of the most technologically advanced guided-missile destroyers in the world”.
      • It has the capability to embark two anti-submarine warfare helicopters and is packed with sophisticated state-of-the-art weapons and sensors, including surface-to-surface and surface-to-air missiles, medium and short-range guns, anti-submarine rockets and advanced electronic warfare and communication suits. 
      • It is capable of undertaking multifarious tasks and missions spanning the full spectrum of maritime warfare.

    Project 15B ships

    • The Rs.35,000 crore Project 15B envisages the construction of four stealth guided-missile destroyers, with the remaining three to be commissioned between 2023 and 2025.
      • These ships have been designed indigenously by the Directorate of Naval Design, New Delhi. 
    • Project 15B ships “feature cutting-edge advanced technology and are comparable to the best ships of similar class anywhere in the world“. 
    • The ships also feature enhanced stealth features — which make them difficult to detect — that have been achieved through “shaping of hull and use of radar transparent deck fittings”.
    • The ships run on four gas turbines and incorporate new design concepts for “improved survivability, sea keeping, stealth and manoeuvrability”.
    • P 15B ships will be equipped to carry and operate two multiple role helicopters.
