The Visakhapatnam-class destroyers, or P-15 Bravo-class destroyers, or simply P-15B, is a class of guided-missile destroyers currently being built for the Indian Navy. The P-15B destoyers, are a follow-up on the earlier-P-15A destroyers. A total of four vessels - Visakhapatnam, Mormugao, Imphal and Porbandar, will be built in India by Mazagon Dock Limited (MDL)[18][14]The P-15B class are noted to have substantial improvements in weaponry, technology and stealth, over the P-15A class.[19]

Development

See also: Kolkata-class destroyer

In January 2011, the Cabinet Committee on Security approved for a follow-on class of the earlier Project 15A Kolkata-class destroyers. The aim of the follow-on class was to retain the same hull as the earlier class but incorporate significant changes in the superstructure and improve the ship's stealth characteristics. A total of four destroyers were ordered under Project 15B with a total cost of ₹29,340 crore (US$4 billion).[20][21] However, the overall cost is around ₹35,800 crore (US$4 billion) which includes a weapons and sensor package cleared in January 2020.[22]

Construction

Construction for the class began in 2013 and the keel of the first ship was laid in October 2013.[23] The build time for the class is expected to be shorter than the Kolkata class, as no major re-designing involved. Due to this, each warship is expected to save US$1 billion in costs. The first ship was launched on 20 April 2015 and is expected to join the Indian Navy by 2021, with the follow on ships being delivered annually.[18][24]

The first ship of the class - Visakhapatnam successfully completed its basin trials in December 2020, and is scheduled to be delivered to the Indian Navy, approximately by late-2021.[25][26]

The Visakhapatnam-class shares similar dimensions to the previous Kolkata class, however it incorporates a flush deck, a better acoustic signature and infrared signature reduction systems. The class has a displacement of 7,400 tonnes (or 7,300 long tons).[3][27] It has been designed by Indian Navy's in-house unit Directorate of Naval Design. Saint Petersburg's Northern Design Bureau was consulted during the design phase to reduce the size of design's superstructure. Russia's Baltic Shipyard was contracted to provide four sets of line shafts while the Zorya gas turbines of the ship were sourced in Ukraine.[28][29][27][30][31]L&T has been contracted to provide Integrated Platform Management System, Automated Power Management System, main switchboard, degaussing system and DA local control panels. According to the Indian Navy, 65 percent of the class will be indigenously sourced, including eleven of its weapon and sensor systems.[32][14]

The class have a length of 163 m (535 ft), a beam of 17.4 m (57 ft) and a draught of 6.5 m (21 ft) and a maximum speed of over 30 knots.[33] Aviation facilities include an enclosed deck and is capable of operating two helicopters simultaneously. The class will be fitted with the Nirbhay land-attack cruise missile, 8-16 supersonic BrahMos anti-ship and land-attack missiles and 32 Barak 8-ER SAMs. All the missiles will be fitted into a Universal Vertical Launcher Module (UVLM). Four AK-630 close-in weapon systems (CIWS) will provide the ship with close-in-defence capability. Twin tube torpedo launchers and RBU-6000 Smerch-2 rocket launchers will provide anti-submarine warfare capability.[34][14] The primary radar sensor of the class is the EL/M-2248 MF-STAR multi-mission AESA. It is also equipped with Thales LW-08 long range volume search radar.[14] Each ship of the class will have a complement of 50 officers and 250 sailors.[35]

Difference with Kolkata-class destroyers

Visual differences between the Kolkata-class destroyers, and the Visakhapatnam-class destroyers.
The Kolkata-class destroyer (up), and the Visakhapatnam-class destroyer (down). Notice the physical difference between both destroyers, especially the bridge layout.

The P-15A (Kolkata-class) destroyers and the P-15B (Visakhapatnam-class) destroyers have no major physical differences, except for the differing bridge layouts; the bridge of the P-15B destroyers starkly differs to that of the P-15A - they were designed in such a way so as to reduce radar cross-section (RCS), and to improve survivability.[4][36]

The P-15A and the P-15B destroyers differ from each other, in terms of equipment.[37][38][14]

  • The P-15B class is armed with a 127 mm gun, while the P-15A class is armed with a 76 mm gun.
  • The sonar will be relocated from the hull to the bow.
  • A revised bridge layout and mast design to reduce radar cross-section (RCS).
  • A "rail-less helicopter" traversing system to secure the helicopter, in case of adverse weather conditions at sea.
  • A network-centric layout with a Ship Data Network (SDN), an Automatic Power Management System (APMS) and a Combat Management System (CMS).
