DELHI CLASS GUIDED MISSILE DESTROYER

DELHI GUIDED MISSILE DESTROYER

Delhi Class destroyers were built for the Indian Navy by Mazagon Dock based in Mumbai, under the Project 15 programme. The Delhi destroyer was designed by the Indian Navy with the detailed and production design phase carried out by Mazagon Dock. With a displacement of 6,700t, overall length of 163m and beam of 17m, the Delhi Class is the largest warship built in India. The ship is fitted with sophisticated anti-ship, anti-aircraft and anti-submarine sensor and weapon systems.

The ship's integrated combat data system is supplied by Bharat Electronics Ltd (BEL) of Hyderabad. The main gun at the bow of the ship is a 100mm gun supplied by Russia. The ship is also fitted with four six-barrel AK 650 gatling guns. The ship is equipped with four quad launchers for the Uran anti-ship missile system. The Uran system launches the Kh-35 (Nato designation SS-N-25) antiship cruise missile, which uses an inertial guidance system to steer the missile towards the target area and an active radar homing head for terminal guidance. The minimum and maximum ranges of the missile are 5km and 130km. The surface-to-air missile system is the Russian Shtil (SA-N-7), known by the Nato reporting name Gadfly. The missile's maximum range is 25km. It was envisaged that this would be replaced with the Trishul surface-to-air missile system, which had a range of 500m to 9km and a 15kg warhead. In December 2006, the Indian MoD stopped the research and development of Trishul and focused on developing the Barak defence missile system.

"The Delhi Class is fitted with the Rafael Barak point air defence missile system."

The ship's radar suite includes Rashmi I-band navigation radar by Bharat Electronics, Russian Kite Screech and Bass Tilt H,I and J band fire control radars for the guns, Garfun B fire control radar for the Kh-35 Uran SSM, Front Dome fire control radar for the SA-N-17 SAM, RALW - LW08 air search radar operating in D-band and supplied by Bharat Electronics Ltd and Thales Nederland (formerly Signaal) and the Bharat / Thales RAWS - DA05 E-band surface search radar. The ship's hull mounted active search sonar capability is based on the TSM2633 by Thales Underwater Systems or the APSOH by Bharat.

The Delhi Class also has a variable depth sonar, Model 15-750 developed and manufactured in India by Indal and Garden Reach. The ship's propulsion is based on a combined diesel and gas CODAG system. The propulsion system drives two shafts and provides a maximum speed of 28kt.
