INS Udaygiri
Why it Matters?
INS Udaygiri, the second stealth frigate under Project 17A, was inducted into the Indian Navy on July 1, 2025, marking a significant boost in indigenous naval capabilities and shipbuilding efficiency.
What You Should Know?
INS Udaygiri is the second ship of the Project 17A (P-17A) stealth frigates, delivered to the Indian Navy in a record time of 37 months from its launch.
These multi-mission stealth frigates are capable of operating in blue water environments, dealing with conventional and non-conventional threats across India's maritime interests.
The frigate is a modern avatar of the earlier INS Udaygiri, which was decommissioned in 2007 after 31 years of service.
It marks a quantum leap in indigenous warship design, being designed in-house by the Indian Navy’s Warship Design Bureau.
The ship is equipped with a supersonic surface-to-surface missile system, a medium-range surface-to-air missile system, a 76 mm main gun, and 30 mm & 12.7 mm close-in weapon systems (CIWS), making it a potent platform for layered maritime defence.
Project 17A is the successor to Project 17 (Shivalik-class), with enhanced stealth design, state-of-the-art weaponry, and superior naval systems.
These ships are being built at Mazagon Dock Shipbuilders Ltd. (MDSL), Mumbai, and Garden Reach Shipbuilders & Engineers, Kolkata.
The hull of P-17A ships is geo-symmetrically larger by 4.54% compared to the P-17 class, allowing for greater operational capacity and survivability.
It is built under the 'Integrated Construction' method, which uses pre-outfitted blocks to reduce build time and improve efficiency.
It is designed in-house by the Indian Navy’s Warship Design Bureau; the ships signify a quantum leap in indigenous naval design and self-reliance.
It is configured with a Combined Diesel or Gas (CODOG) propulsion system combining a diesel engine and gas turbine driving a Controllable Pitch Propeller (CPP) on each shaft.
It is equipped with an Integrated Platform Management System (IPMS) for automated control and monitoring of shipboard machinery and systems.
The remaining five P-17A ships will be delivered progressively by the end of 2026, reinforcing India’s naval strength and self-reliance in defence production.
