Khukri-class

The Khukri-class corvette, designated Project 25, was developed for the Indian Navy to replace the Petya II-class. The Indian government ordered the first two vessels in December 1983 and the remaining two in 1985. The class was constructed by Mazagon Dock Limited and Garden Reach Shipbuilders and Engineers. The design follows the Veer class and preceded the Kora class.

The ships incorporate indigenous content, including diesel engines assembled in India under license by the Kirloskar Group. The class is equipped with air search, surface search, and fire control radars, as well as navigation systems. Electronic warfare capabilities include electronic support measures, chaff launchers, and a towed torpedo decoy. The design facilitates the operation of a single HAL Chetak or HAL Dhruv helicopter.

Four vessels were completed and commissioned between 1989 and 1991. The lead ship, INS Khukri, was decommissioned in December 2021 and subsequently converted into a museum ship in Diu. INS Kirpan served in the Indian Navy until July 2023, when it was decommissioned and transferred to the Vietnam People's Navy. It now operates under the designation Ship 26. As of 2023, two vessels, INS Kuthar and INS Khanjar, remain in active service with the Indian Navy.
