List of destroyer classes of the Indian Navy

[7][8][9] During the 1980s, India signed an agreement with the Soviet Union for five guided-missile destroyers, built as the Rajput class.

The Rajput-class destroyers, which preceded the Delhi class, consists of five ships built in the Soviet Union and were commissioned from 1980 to 1990.

[18][19] The class will have enhanced stealth characteristics and state-of-the-art weaponry and sensors, including the long-range Barak 8 surface-to-air missile.

[31] It consists of three ships (Kolkata, Kochi and Chennai), built by Mazagon Dock Limited, which are the navy's largest destroyers.

[32] Although the dimensions of Kolkata-class ships are similar to the previous Delhi class, their weaponry, sensors and helicopter systems have been upgraded.

[35] The ships' main air-defence armament is two 4 × 8-cell vertical launching systems (VLS) allowing up to 32 Barak 8 (medium- to long-range) missiles.

[14] The Kolkata-class ships' primary offensive armament is supersonic BrahMos anti-ship and land-attack missiles.

The 76 mm gun provides limited anti-shipping and anti-air capability in addition to naval gunfire support for land-based operations.

[40] The Delhi-class vessels are the third-largest warships designed and built in India, after the Kolkata-class destroyers and the Shivalik-class frigates.

[17] Delhi-class design has Soviet and Western influences, incorporating elements of the Sovremenny, Rajput and Kashin-II-class destroyers and the Godavari-class frigate.

[47] Delhi-class vessels are fitted with flag facilities, enabling them to act as command unit in task groups.

[47] The vessels are equipped to enable operation in a nuclear, biological and chemical warfare environment.

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

[49] The Delhi class is being upgraded with the Rafael Barak 1 point air defence missile system.

It has a pair of eight-cell vertical launch systems and missile command-to-line-of-sight (CLOS) radar guidance with a range of 10 km (6.2 mi).

[10][12][51] The Indian Navy is planning to upgrade the propulsion of Rajput-class ships with an indigenously-developed Kaveri marine gas turbine (KMGT) engine.

[52] All presently decommissioned Indian Navy destroyers were built in the United Kingdom and Soviet Union.

Since they had fewer main guns than the J, K and Ns, magazine space was replaced by fuel bunkers[56] allowing for 4,675 nautical miles (8,658 km) at 20 knots (37 km/h).

[57] The R class repeated the Qs, except that the officers' accommodation was moved from the traditional right aft to a more accessible location amidships.
