INS Chennai is the third ship of the Kolkata-class destroyers being built for the Indian Navy. She is under construction at Mazagon Dock Limited (MDL) located in Mumbai. INS Chennai has been built under the code name of Project 15 Alpha.

Project 15A (15 Alpha) Kolkata Class destroyers are a follow-on of the Type 15 Delhi Class destroyers. The concept and function for Project 15A was framed by the Navy’s Directorate of Naval Design, while the detailed design was developed by Mazagon Dock Limited (MDL),Mumbai.

The P15A guided missile destroyer possess enhanced stealth features and land-attack capabilities and is expected to add a new dimension in naval warfare for the Indian Navy. Project 15A has advanced weapons and sensors and is technologically far more superior than its predecessor Delhi-class destroyers.

Development and Launching

The INS Chennai Destroyer’s keel was laid in February 2006 and was launched on 2 April 2010.The Ship was launched by Smt Elizabeth Antony wife of the Defence Minister Shri AK Antony. Defence Minister AK Antony said on the launching that India should have indigenous warship manufacturing capability and that the country cannot depend on foreign shipyards.

The Destroyer is expected to be commissioned in by late 2015 or early 2016.The ships in this class are the largest warships or destroyers ever constructed at Mazgaon.INS Chennai will be the first naval ship named after Chennai,capital of Tamil Nadu.

The lead ship INS Kolkata and its sister ship INS Kochi have already been launched.

The Project 15-A is about 90 percent indigenous by cost. And the design itself is 100 per cent Indian. The three Project 15-A Kolkata-class destroyers will each cost the navy Rs 3,800 crore (US $950 million), including the cost of long-term spare parts. Three 6,250-ton destroyers, fitted with the Aegis radar and fire control system, will set Australia back by Rs 32,000 crore (US $8 billion). At about Rs 11,000 crore per destroyer, that is almost three times the cost India is paying for its Kolkata-class destroyers.

Russia is assisting Project 15-A not only with shafting and propellers, but also the know-how for pontoon-assisted launches. Conventionally, a ship is “launched” into water once its hull is completed, after which the superstructure — the upper decks and masts that together weigh several thousand tonne — is fitted on in deeper water. The shallow water near the slipways, where warships are built, cannot accommodate fully built warships, which require a deeper draught.

Design and Features

INS Chennai, The Kolkata-class Destroyer have a length of 163 mts, width of 17.4 mts and displacement of 7,500 tonnes.

The indigenously designed ship will have state of the art weapons and sensors, stealth features, an advanced action information system, a comprehensive auxiliary control system, world class modular living spaces, sophisticated power distribution system and a host of other advanced features.

The destroyer’s sides are covered and rounded which makes detection difficult.This will easily hide the all missile launchers and bases of the superstructure and no other/ enemy ships will see the launchers.

 Engine and Electronic Warfare

INS Chennai The Kolkata Class destroyer is propelled by four gas turbines (Zarya reversible gas turbines from Ukraine). It can achieved the maximum speed of 30 kn (56 km/h).

THE Electronic warfare and decoys systems includes Elbit Systems Deseaver MK II countermeasures system and Defensive aids suite 1.

INS Chennai will be incorporated with Advanced BEL Electronic Modular Command & Control Applications (EMMCCA Mk 4) combat management system.It will also equipped with Thales LW-08 D-band air search radar,IAI EL/M-2248 MF-STAR(Threat Alert Radar) S-Band AESA Multi-Function Radar and IAI EL/M-2238 L-band Star surveillance radar.

There are two sonar integrated;BEL HUMSA-NG Bow sonar(Hull Mounted Sonar Array new generation) and BEL Nagin active towed array sonar jointly developed by the DRDO’s Naval Science and Technology Laboratory in Visakhapatnam and Bharat Electronics Limited in Bangalore.

All sensors and weapons are integrated in a state-of-the-art system; the networking of the weapons and sensors will enable the warship to combat multi-threats in different dimensions simultaneously.

Armament of INS Chennai

INS Chennai will be packed with an array of state of the art weapons. The destroyer will be armed with world’s leading supersonic BRAHMOS cruise missile. The BRAHMOS missile system will enable the ship to engage shore based and naval surface targets at long ranges, making it a lethal platform for strike against enemy targets.

Brahmos Hypersonic Cruise missile

The ship’s air defence capability, designed to counter the threat of enemy aircraft and anti-ship cruise missiles will revolve around the vertical launch, long range surface- to-air missile system which is being co-developed by DRDO.

4x AK-630 rapid-fire guns will provide the ship with close-in-defence capability while an MR 130mm gun will enable INS Chennai to provide effective naval gunfire support.

The Destroyer is also armed with Indigenously developed twin tube torpedo launchers and 2x RBU-6000 rocket launchers which will add punch to the ship’s anti-submarine capability.

Aircraft Carrier

INS Chennai will carry two Sea king Medium Lift Transport/utility helicopter  or HAL Dhruv Multirole Utility helicopter or Both 1 x 1.
