In a significant step for indigenous naval shipbuilding, the Indian Navy is preparing to induct two Project-17 Alpha (P-17A) frigates in Visakhapatnam. These modern warships are part of a 2015 program to expand India’s frontline combat fleet. The INS Himgiri (F34), developed by Garden Reach Shipbuilders & Engineers in Kolkata, and INS Udaygiri (F35), produced by Mazagon Dock Shipbuilders in Mumbai, will enter service together, marking the first dual commissioning from different shipyards in the same city.
Both platforms successfully cleared rigorous sea trials, validating their systems for deployment, including propulsion, navigation, firefighting, and damage-control mechanisms. The program also highlights India’s defense-industrial ecosystem, as more than 200 MSMEs were involved, generating 4,000 direct and 10,000 indirect jobs nationwide.
The Nilgiri-class frigates, evolved from the earlier Shivalik-class, feature advanced technology and enhanced operational capabilities. Measuring 149 meters in length with an 18-meter beam, they are equipped with a combined propulsion system of General Electric LM2500 and MAN Diesel engines, achieving speeds of up to 32 knots and endurance of 5,500 nautical miles.
Each ship can accommodate 150 sailors, operate a maritime helicopter, and deploy two inflatable boats. Their arsenal includes naval guns, remote-controlled weapons, and a range of missiles designed for air, surface, and underwater combat. With INS Nilgiri already commissioned earlier this year, India remains on track to complete all seven ships under the P-17A program by 2026.
