NotesFirst major class of Indian-designed warships to be built using integrated modular construction.[4]

The Nilgiri-class frigates, formally classified as the Project-17 Alpha frigates (P-17A), are a series of stealth guided-missile frigates currently being built by Mazagon Dock Shipbuilders (MDL) and Garden Reach Shipbuilders & Engineers (GRSE) for the Indian Navy (IN).[5][6]

Designed by the Warship Design Bureau, the class is intended to serve as a complement to the currently-serving Shivalik-class frigates (P-17) with improved design portfolios, such as low radar cross-section (RCS) and reduced infrared signature.[7][8]

With a total of seven vessels, the construction of the frigates are currently divided between MDL and GRSE.[5][6] As of 2024, all seven frigates have been launched and are intended to enter service with the IN between 2024 and 2027.[9] The frigates will form a part of the Eastern Fleet as well as the future Carrier Battle Group (CBG) of INS Vikrant.[10]

Upon entering service, the class is to be complemented by an additional series of seven or eight frigates, under the codename the Project-17B series.[11][12]
