Development
The design and development of the ship class began as "Project 15" in 1980. Initially, the ships were planned to be follow-on frigates of the Godavari class with the addition of RBU-6000 ASW rocket launchers and gas turbine propulsion. A Soviet offer in 1983 for reversible gas turbines and modern weapon systems forced a redesign of the ships from 3,500-tonne frigates to 6,300-tonne destroyers.[9] The Directorate of Naval Design completed the design around the mid 1980s.[10] Model tests were carried out at SSPA, Sweden in 1985 and parallelly at Krylov Institute, Soviet Union in 1986. Severnoye Design Bureau provided design inputs for weapons and propulsion packages. The mutual interface suppression system for electromagnetic compatibility was supplied by the Soviets.[9] The break-up of the Soviet Union affected the supply of weapon systems, contributing to a three-year delay in the construction of vessels.[7]
Design and description
The Delhi class has been described as a stretched
Armament
For air defence role, Delhi class is fitted with
The surface missile battery of Delhi class includes 16 Kh-35E Uran missiles placed in four quadruple sloped launchers. The missiles feature active radar homing and are guided by a Granit Garpun B (NATO: Plank Shave) fire-control radar. They have a maximum range of 130 kilometres (81 mi) and are capable of sea skimming.[2] The missile battery was initially intended to be eight 3M80E Moskit cruise missiles as evidenced by large blast deflectors present on the lead ship, INS Delhi. A single AK-100 gun guided by MR-184/MR-145 fire-control system (NATO: Kite Screech), which comprises T-91E radar and Kondensor electro-optical sights, was originally fitted to the ships.[11][13] The three ships have replaced the 100mm guns with OTO Melara 76 mm naval gun during refits in the early 2020s.
A quintuple 533-millimetre (21 in) trainable torpedo launcher capable of firing SET 65E active/passive homing torpedo and
The electronic warfare suite originally consisted of BEL Ajanta Mk 2 for
Modernisation
As of January 2024, INS Delhi(D61) and INS Mumbai(D62) has completed their mid-life refit that includes upgrades for several weapons and sensors. The Kh-35E Uran missiles has been replaced by BrahMos missiles, which was originally sanctioned in 2015 for two ships of this class. The primary radar has been replaced with Fregat M2EM radar from the older MR-755 Fregat-MAE. The AK-100 main gun has been replaced by OTO Melara 76 mm along with BEL Lynx U2 FCR. The electronics warfare system is upgraded to Ellora Mk II, with Kavach decoy launchers.[17][18] Atlas Elektronik ACTAS towed-array sonar will be installed on all three ships.[19] In April 2022, Brahmos missile was tested from INS Delhi (D61) with. new sloped Launcher design.
Relocation
The Delhi-class destroyers will be re-based to the Eastern Naval Command, Visakhapatnam. Along with Nilgiri class, these will form a part of the carrier battle group of Vikrant. Mysore had reached its new base by December 2021 and was undergoing refit.[20]
