The three Indian Navy destroyers of the Delhi class are the most modern and largest to be fully built in India. They began as Project 15 in 1977, initially as frigates to replace the Godavari class. They were manufactured at Mazagon Dock Limited in Mumbai.
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 6,700 tonne guided-missile destroyer INS Delhi is India's first "Stealth Warship". Described as the Navy's version of the Russian Kashin Class destroyer, the Delhi was the first Principal Surface Combatant to join the Indian Navy. The destroyer is fitted with sophisticated anti-ship, anti-aircraft and anti-submarine sensor and weapon systems.
INS Delhi is the first Indian warship to be fitted with air and surface search radar. These vessels are well suited for power projection roles in the Indian Ocean Region and are fully fitted with flag facilities. The Delhi Class is also capable of operating in a NBC environment and Radar-Cross-Section reduction is presumed to be minimal, to the extent that some sharp angles have been flattened.
The 100 mm main gun at the bow of the ship is supplied by Russia. The vessel is equipped with four quad launchers. The surface-to-air missile system is the Russian Shtil. The missile's maximum range is 32 km. The ship has a surveillance capacity of over 350 km and can sterilise an area of 250 km.
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.
In the main air defence role, a pair of 2 3S-90 launchers - one installed forward of the bridge and the other atop the dual helicopter hangar - are fitted with the Shtil SAM system. The Shtil system is comprised of the Russian Shtil missile and 24 such missiles are carried in a below-decks magazine. The launchers elevate up to 70º but have a limited firing arc of 30º within the centreline. The launcher groups require a crew of 20 men and weigh about 50 tons.
The ships also have a quadruple 533mm torpedo launcher, which can also be used to launch SS-N-15 'Starfish' or possibly SS-N-16 'Stallion' ASW missiles, so is capable of hitting targets ranging from 50 km to 120 km. It is also equipped with two RBU-6000 anti-submarine rocket launchers with 12 tubes. Their range is 6 km and the maximum engagement depth is 500m.
The ship can support two helicopters, the new Dhruv Advanced Light Helicopter (ALH) by Hindustan Aeronautics Ltd (HAL) and the AgustaWestland Sea King helicopters. The Delhi-class carry two Sea King helicopters, primarily equipped with a Super Searcher radar for the air surveillance role. The helicopters are capable of flying four and half hours non-stop. They are capable of both anti-submarine as well as anti-surface operations and can take off from the vessel within five to ten minutes. The INS Delhi has a crew of approximately 30 officers and 350 sailors.
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 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.
Delhi class is a multi-role destroyer is capable of tackling threats in all dimensions, air, surface and underwater. The ship was designed indigenously and built by Mazagon Docks Limited (MDL) at a cost of Rs 700 crore.
