Introduce

The Indian Navy owns an aircraft carrier, 11 destroyers, 13 missile frigates, 14 non-nuclear submarines, 2 nuclear submarines and many other warships. It can be said that India is the country with Asia’s leading navy force.

The Indian Navy’s most powerful fists are the Kolkata-class destroyers built by the Indian shipbuilding industry. Kolkata has a displacement of 7,400 tons and is equipped with a powerful fire system. Especially these warships carried the world’s most feared anti-ship missile, the BrahMos.

Another powerful Indian warships is the Delhi-class guided-missile destroyers, with a displacement of 6,200 tons. It was once India’s largest warships until the Kolkata class entered service. Currently three Delhi-class destroyers are in service of the Indian Navy, INS Delhi is the lead ship.

Delhi is the second vessel of the Indian Navy to bear the name, she inherits the mantle from the Leander-class cruiser of the same name.

Background

INS Delhi is known as part of “Project 15”, planned in 1980. The design of the ship was based primarily on the Soviet Kashin-class destroyer, and the design was also taken from Godavari and Sovremenny classes.

Delhi was laid down in 1987 and launched in 1991 but due to the collapse of the Soviet Union, the weapons system was delayed in delivery. As a result, it was not until 1997 that the ship officially went into operation, she was built at Mazagon Dock Limited in Mumbai.

INS Delhi, together with her sisters, is a multinational platform, with Russian Kashmir surface-to-air missiles, Canadian sonar mountings, Dutch radars, French and Italian electronic systems.

Design

Delhi’s design is thought to be quite similar to the Rajput-class destroyer, the fore funnel is placed on the port side, while the aft funnel is placed on the starboard. The 6200-ton destroyer is 163m long, the beam is 17m and the draft is 6.5m.

The vessel is equipped for operation in a nuclear, biological and chemical warfare environment. She is fitted with flag facilities, enabling her to act as command unit in task groups. At the stern, there is a spacious helicopter landing deck and two hangars, to accommodate operations of two helicopters.

The helicopters could be the Dhruv advanced light helicopter or the new Chetak helicopter of Hindustan Aeronautics Ltd, or the AgustaWestland Sea King helicopter, primarily designed for anti-submarine warfare missions. The ship can accommodate 350 people, including 40 officers.

Propulsion

She is equipped with four Zorya-Mashproekt DT-59 gas turbines, driving two controllable-pitch propellers. The propulsion system provides 82,820 horsepower, enabling the ship to reach a maximum speed of 32 knots, a range of up to 4500 nautical miles at 18 knots.

Armament

For air defence role, the Delhi is fitted with 9K-90 Uragan air-defence system comprising a pair of 3S-90 single-arm launchers and 9M38M1 Shtil missiles.

One launcher is installed forward of the bridge and the other atop the dual helicopter hangar. MR-775 Fregat-MAE radar provides target designation and 6 MR-90 Orekh illuminators are used for fire control. The system can track twelve targets and engage a maximum of six tracked targets simultaneously.

Last-ditch missile defence is provided by a close-in weapon system consisting of four AK-630 rotary cannons guided by two MR-123-02 fire-control radars. A Signaal LW08 radar license produced by BEL as RAWL provides long range air search capability.

The surface missile battery of Delhi includes 16 Kh-35E Uran missiles placed in four quadruple sloped launchers. The missiles are guided by a Granit Garpun B fire-control radar. A single 100mm AK-100 gun guided by MR-184 fire-control system is also fitted.

A quintuple 533-millimetre trainable torpedo launcher capable of firing SET 65E active and passive homing torpedo is placed in between the funnels.

A pair of 12-tubed RBU-6000 213mm anti-submarine rocket launchers fitted in front of the bridge can engage submarines up to a range of 6 km.

Detection is provided by BEL HUMVAD, an indigenous hull-mounted sonar with a variable depth transducer that offers better performance in the waters around India. An Indal Model 15-750 handling system manufactured by GRSE is used to deploy the variable depth sonar of HUMVAD.

The electronic warfare suite consists of BEL Ajanta Mark 2 for electronic support measures, Elettronica TQN-2 jammer and two PK-2 chaff launchers of Russian origin. BEL Shikari combat display and management system, a derivative of Italian IPN-10, integrates weapon systems of diverse origin. In the near future, the destroyer will be modified to equip BrahMos supersonic cruise missiles.
