INS Kolkata is the lead ship in the guided class destroyers. The other two would be INS Kochi and INS Chennai.
Construction of three Kolkata-class ships was sanctioned by the Government of India in May 2000, and steel for the lead ship was cut in March 2003.
Construction began in September 2003 at Mazagon Docks, Mumbai, with an initial expectation that the first of the class would be handed over to the navy by 2010.
