PM Dedicates INS Kolkata to the Nation
Aug 20, 2014

The Minister of India, Narendra Modi, commissioned INS Kolkata into the Indian Navy recently at the Naval Dockyard, Mumbai. INS Kolkata is the lead ship of the indigenously designed and constructed Kolkata-class guided missile destroyers, built by Mazagon Dock Limited, Mumbai. The commissioning of INS Kolkata is a milestone in the self-reliance programme of the Indian Navy and indigenisation of platforms, weapons, sensors and equipment, through public as well as private sectors, will continue to remain a focus area. The Roadmap for the Navy’s expansion and growth would continue to remain firmly anchored on Self-reliance and Indigenisation. 

The Project 15A Kolkata class destroyers are follow-on of the legendary Project 15 Delhi class destroyers which entered service in the late 1990s. Conceived and designed by Indian Navy’s Directorate of Naval Design, the ships have been christened after major port cities of India viz. Kolkata, Kochi and Chennai. The keel of Kolkata was laid on 26 September 2003 and the ship was launched on 30 March 2006.

Regarded as the most potent warship to have been constructed in India yet, this magnificent ship measures 164 meters in length and approximately 18 meters in width and has a full load displacement of 7400 tonnes. The ship has a Combined Gas and Gas (COGAG) propulsion system, consisting of four powerful reversible gas turbines and can attain speeds in excess of 30 knots. The ship’s electric power is provided by four gas turbine generators and one diesel alternator, which together produce 4.5 Mega-Watts of electrical power, enough to light up a small town. The ship has a complement of 30 officers and 300 sailors. 

INS Kolkata incorporates new design concepts for stealth and has many firsts to her credit, including a very large indigenous combat component. The ship is packed with the most sophisticated state-of-the-art weapons and sensors including the vertically launched Long Range Surface to Air Missiles (LRSAM) coupled with the MF-STAR multi-function active phased array radar, which is fitted for the first time on an Indian Naval ship. She is equipped with advanced supersonic and long range BrahMos Surface to Surface Missiles. The 76 mm Super Rapid Gun Mount (SRGM) and AK 630 CIWS, both manufactured indigenously, can take on air and surface targets. The entire anti-submarine weapon and sensor suite fitted onboard, consisting of Indigenous Rocket Launchers (IRL), Indigenous Twin-tube Torpedo Launchers (ITTL) and a bow-mounted New Generation HUMSA Sonar are a fine example of our indigenous efforts in the field of underwater warfare. The sensor suite includes other advanced surface and air surveillance radars and an indigenous Electronic Warfare system. A state-of-the-art Combat Management System (CMS-15A) has been integrated with the onboard weapons and sensors. The ship is equipped to operate two Seaking or Chetak helicopters. 

The ship can be truly classified as a Network of Networks as it is equipped with sophisticated digital networks, such as ATM based Integrated Ship Data Network (AISDN), Auxiliary Control System (ACS), Automatic Power Management System (APMS) and Combat Management System (CMS). The AISDN is the information highway on which data from all the sensors and weapons ride. Whilst remote control and monitoring of machinery is achieved through ACS, the intricate power supply management is done using APMS. The CMS is used to integrate information from own data sources and collate information from other platforms using indigenous data-link system, to provide maritime domain awareness. 

The unique feature of this ship is the high level of indigenisation achieved with most of the systems onboard sourced from within the country which has generated a sound vendor base for future ships. Some of the major indigenised equipment/ systems onboard INS Kolkata include Combat Management System (CMS), Auxiliary Control System (ACS), Automatic Power Management System (APMS), Foldable Hangar Doors, Helo Traversing System and bow mounted HUMSA NG system. Crew comfort is a significant feature of INS Kolkata and has been ensured through ergonomically designed accommodation and galley compartments on modular concept.
