The Indian Navy has commissioned its indigenously-designed new Kolkata-class (Project 15A) guided missile destroyer, INS Chennai, at the Naval Dockyard in Mumbai, enhancing the nation’s defence capabilities.
INS Chennai represents the third and last of the Kolkata-class destroyers built by Mazagon Dock Shipbuilders, Mumbai.
Construction of the three Kolkata-class destroyers was approved by the Indian Government in May 2000 and INS Kolkata was the first vessel commissioned in 2014, followed by INS Kochi in 2015.
Indian Defence Minister Manohar Parrikar said: “With the induction of INS Chennai, a new benchmark has been achieved for our warship design and construction endeavours, with the sophistication of systems and equipment, and utilisation of advanced ship building techniques.”
With a displacement of 7,500t, the 163m-long and 17.4m-wide warship is propelled by four gas turbines in a combined gas and gas (COGAG) configuration to achieve a speed of more than 30k.
The new destroyer features reduced radar cross section (RCS), which was achieved through shaping of hull, full beam superstructure design, plated masts and use of radar transparent materials on exposed decks.
The vessel is equipped with a modern surveillance radar, indigenously developed rocket launchers and torpedo launchers, an auxiliary control system, and bow mounted sonar.
It can conduct missions under nuclear, biological and chemical (NBC) warfare conditions.
