Indian Navy Inducts Indigenous Stealth Frigate ‘Udaygiri’ Under Project 17A.
Science and Technology
On 1st July 2025, the Indian Navy commissioned its indigenous stealth frigate Yard 12652 (Udaygiri) under Project 17A, built by Mazagon Dock Shipbuilders Limited (MDL), Mumbai. This is the second frigate delivered under P17A and marks a key milestone in India’s defence self-reliance.
- The new frigate INS Udaygiri is named after the decommissioned INS Udaygiri, which served the Navy from 1976 until 2007. The new vessel features advanced stealth capabilities, modular weapons systems, and multi-mission readiness, enhancing India’s blue water naval power projection.
- Project 17A involves building a total of seven advanced stealth frigates for the Indian Navy, designed for combat in blue water environments and built to counter both conventional and asymmetric threats. It is a major follow-up to the older Project 17 (Shivalik-class) warships.
- These ships are designed by the Warship Design Bureau (WDB), New Delhi, and are being built at two Indian shipyards — Mazagon Dock Shipbuilders Limited (MDL) in Mumbai, and Garden Reach Shipbuilders & Engineers (GRSE) in Kolkata, West Bengal.
Main Point :- (i) Udaygiri represents the 100th warship designed by the WDB, highlighting a major achievement in India’s indigenous naval capability. This addition reaffirms India’s focus on building a self-reliant and technologically modernized Navy under the 'Aatmanirbhar Bharat' vision.
(ii) The hull of Udaygiri is designed with 5.44% more length than its predecessors under Project 17, offering better stability, stealth, and capacity. It is equipped to function effectively in deep-sea combat roles with reduced radar signature and improved survivability features.
(iii) Udaygiri includes a Combined Diesel and Gas (CODAG) propulsion system, advanced weaponry like Supersonic Surface-to-Surface missiles, Medium-Range Surface-to-Air Missiles (MRSAMs), 76mm and 30mm naval guns, and Close-in Weapon Systems (CIWS) for layered defence. Its Combat Management System is fully automated for high-response capability.
