The Indian Navy inducted its sixth Project 17A indigenous stealth frigate, INS Mahendragiri, at Visakhapatnam on 12 July 2025, in a commissioning ceremony presided over by Defence Minister Rajnath Singh. The warship, built by Mazagon Dock Shipbuilders Ltd (MDL) in Mumbai, carries over 75 per cent indigenous content and represents the deepest expression yet of India's Atmanirbhar Bharat defence manufacturing push.

A Ship Without a Forerunner

Captain Saikat Chatterjee, Commanding Officer (Designate) of INS Mahendragiri, set the tone for the vessel's identity at the ceremony. 'It's an absolute honour to command an indigenous modern stealth frigate of this stature. And as the commissioning crew, we are conscious of this privilege,' he said.

'Mahendragiri primo temporis. She has no forerunner in the Navy. The ship, therefore, charts its own legacy with a fresh soul and character,' Captain Chatterjee stated. The ship's motto — 'Sthitpragyah, Raneshu, Aprajitah' — translates to steadfast, wisdom, and invincible in battle. 'It is a dictum that guides us to commit ourselves unwaveringly in all actions,' he added.

Captain Chatterjee further pledged: 'We shall remain ever ready and mission-primed to live up to the standards of excellence in the Indian Navy, reflecting the timeless values of duty, honour and courage.'

Capabilities and Design

INS Mahendragiri is among the largest and most advanced frigates ever built and operated in India — and ranks among the largest frigates globally. Designed in-house by the Navy's Warship Design Bureau, it features advanced stealth architecture, a reduced radar signature, enhanced survivability, and a high degree of automation.

The warship is powered by a Combined Diesel or Gas (CODOG) propulsion system, enabling high-speed operations with exceptional endurance. Its weapons suite includes the surface-to-surface BrahMos missile system, the surface-to-air Barak-8 missile system, sophisticated electronic warfare capabilities, comprehensive anti-submarine warfare systems, and an integrated Combat Management System.

Capable of anti-air, anti-surface, and anti-submarine operations, the frigate is also suited for maritime security, power projection, Humanitarian Assistance and Disaster Relief (HADR), and Search and Rescue (SAR) missions across the full spectrum of naval operations.

Atmanirbhar Bharat in Steel

Named after the Mahendragiri mountain range in the Eastern Ghats, the frigate's commissioning at Visakhapatnam strongly suggests it will join the Eastern Fleet. A large number of Micro, Small and Medium Enterprises (MSMEs) were involved in its construction, generating significant employment — a point underlined by the Ministry of Defence in its official statement.

Defence Minister Rajnath Singh had previously articulated the philosophy underpinning such programmes: 'For us, an Atmanirbhar Bharat means a nation brimming with self-confidence, standing firmly on its own feet, and engaging with the world as an equal partner.'

Project 17A: Where the Fleet Stands

INS Mahendragiri is the sixth of seven frigates in the Project 17A class. The fifth, INS Dunagiri, was commissioned in Kolkata on 21 June 2025 by Prime Minister Narendra Modi. The seventh and final vessel, INS Vindhyagiri, remains under construction at Garden Reach Shipbuilders and Engineers (GRSE) Ltd in Kolkata.

The Ministry of Defence described the commissioning as 'another significant milestone in the successful execution of the Project 17A programme,' adding that successive frigates 'continue to strengthen the Indian Navy's combat capability while reinforcing India's position as a leading indigenous warship-building nation.' As INS Mahendragiri begins its service life, the focus will shift to how quickly INS Vindhyagiri completes the class and how the Eastern Fleet integrates these new platforms into its operational doctrine.
