# INS Delhi (D61)

INS Delhi is the lead ship of her class of guided-missile destroyers of the Indian Navy. She was built at the Mazagon Dock Limited in Mumbai and commissioned on 15 November 1997. This class is among the largest warships to be designed and built in India.
As of December 2021, Delhi was transferred to the Eastern Naval Command to replace the ageing Rajput-class destroyers and form the future Carrier Battle Group of INS Vikrant.
The ship completed its mid life upgrade in early 2022 and was back in service by April of the same year. She was back with new sensor upgrades and new 'Modular Launcher' for Brahmos Missile as a replacement for Kh 35E.
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, previously HMS Achilles of Battle of the River Plate fame.
