Namesake

The ship's name is inspired by the Udaygiri mountain range in the Indian state of Andhra Pradesh. Further, this is the second ship of the Indian Navy to be named after the mountain range, the first being a Leander-class frigate, INS Udaygiri with the same pennant number. The former ship was in service between 1976 and 2007.^[13]

Construction and career

This ship is part of the Project-17 Alpha frigates (P-17A), a class of guided-missile frigates currently being constructed for the Navy by Mazagon Dock Shipbuilders (MDL) and Garden Reach Shipbuilders & Engineers (GRSE).^[14]

The ship was laid down on 28 December 2017 and was launched on 17 May 2022.^[15] The ship was delivered to the Indian Navy on 1 July 2025.^[16][17] This was within a record time of 37 months.^[18]

The ship is scheduled to be commissioned, along with Himgiri, 26 August at Naval Dockyard, Visakhapatnam. This would mark the maiden instance, when two major surface ships from two different shipyards are being commissioned simultaneously.^[19][20]
