What It Is
INS Taragiri is a Nilgiri-class Project 17A (P17A) stealth frigate, the third vessel of the class to be commissioned into the Indian Navy in the current build-out (after Nilgiri in December 2025 and Udaygiri). Built by MDL Mumbai, she is named after a mountain peak in the Himalayas, continuing the convention naming P17 frigates after mountain ranges and peaks. Taragiri is fitted with the class-standard COGAG propulsion (GE LM2500 gas turbines), a 32-cell vertical launch system for BrahMos and Barak-8/ER missiles, a 76mm gun, close-in weapon systems, ASW weapons and a multi-role helicopter. She is part of the wider indigenous warship programme that sees MDL and GRSE build the seven-ship class, an anchor of the Indian Navy's modern surface-combatant modernisation. Taragiri was commissioned at MDL Mumbai in 2026 ahead of her sister Mahendragiri's January 2026 commissioning timeline context — the class completed over the first half of 2026.
Deployments & Procurement
Taragiri forms part of the seven-ship P17A programme sanctioned in 2015 (~₹45,000 crore). She was launched at MDL in 2022 and commissioned in 2026. Her commissioning window overlaps the rapid P17A induction in late 2025 to early 2026, when Nilgiri, Udaygiri, Taragiri, and other sisters all entered service within a few months.

Import Dependencies
Taragiri shares the class-standard import set: propulsion, radar technology and missile sub-systems sourced abroad, with the hull and much of the combat system indigenous.
