INS Delhi (D61)

INS "Delhi" (D61) is the name-ship of the "Delhi" class destroyers of the Indian Navy. She was built at the Mazagon Dock Limited in Mumbai (Bombay) and was commissioned on 15 November 1997. Her class is the largest class of warship to built in India.

The "Delhi" class is a hybrid of Soviet and Western designs, incorporating elements of the "Sovremenny" class destroyer, the "Rajput" class (Kashin-II) destroyer, and the "Godavari" class frigate.

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. Trishul is being developed in India and has a range of 500m to 9km and a 15kg warhead. Despite a successful series of firing trials in June 2003, technical problems have put the future of the missile system in doubt. In October 2006, the Indian MOD stated that development would be completed in September 2007.

The Delhi Class is being fitted with the Rafael Barak point air defence missile system. Barak has an eight-cell vertical launch system and the missile command-to-line-of-sight (CLOS) radar guidance with a range from 500m to 10km.

The ship has a quintuple 533mm torpedo launcher which can also be used to launch RPK-2 Viyuga (SS-N-15 'Starfish') or possibly RPK-6 Vodopad (SS-N-16 'Stallion') ASW missiles.

The ship also has two RBU-6000 anti-submarine rocket launchers with 12 tubes. Range is 6km and the maximum engagement depth is 500m.

The ship is equipped with four chaff launch systems and the Ajanta radar interceptor developed by Bharat Electronics Limited of Bangalore. The TQN-2 jamming system is supplied by the Italian company, Elettronica.

The Delhi Class also has a variable depth sonar, Model 15-750 developed and manufactured in India by Indal and Garden Reach.
