NEW DELHI — The Indian Navy commissioned the indigenous stealth frigate INS Mahendragiri on 23 September 2026, marking a milestone in the country’s maritime self‑reliance drive. The ceremony, held at the Mazagon Dock Shipbuilders Limited yard in Mumbai, was attended by Vice Admiral S. K. Sinha, Chief of Naval Staff, and Defence Minister Rajnath Singh.
Indigenous design and advanced stealth
INS Mahendragiri is the twelfth ship of the Project 17A class, a series of 12 stealth frigates built by Mazagon Dock Shipbuilders Limited (MDL). The vessel cost approximately ₹7,000 crore and incorporates angled hull plating, radar‑absorbent coatings, and a reduced radar cross‑section that makes it harder to detect by conventional radar systems. The ship carries a 76‑mm OTO MARTINI gun, a 30‑mm remote‑controlled weapon station, and a suite of anti‑ship and anti‑air missiles, including the BrahMos cruise missile and the Barak‑8 surface‑to‑air missile. An integrated combat system links a 3D AESA radar, a hull‑mounted sonar, and an electronic warfare suite.
Strategic implications for the Indian Ocean
Commissioning INS Mahendragiri expands the Indian Navy’s surface combatant fleet to 12 Project 17A frigates, a 20‑percent increase over the current 12‑ship complement. The frigate’s advanced sensors and weapons enable it to operate independently in the Indian Ocean Region, supporting anti‑submarine warfare, maritime interdiction, and escort missions for carrier strike groups. Defence Minister Rajnath Singh said the ship “will strengthen India’s maritime deterrence and enhance our ability to safeguard sea lines of communication.”
Future deployments
INS Mahendragiri will join the 12th Frigate Squadron at the Naval Dockyard in Mumbai. The squadron will conduct regular patrols in the Arabian Sea and the Bay of Bengal, and will be available for rapid deployment to the Gulf of Aden and the Strait of Hormuz. The ship’s crew of 200 personnel will undergo a 12‑month training cycle before the vessel is assigned to operational duty.
India’s defense production push
The commissioning underscores India’s “Make in India” initiative, which aims to reduce dependence on foreign defense imports. Project 17A frigates are built entirely with domestic technology, with 90 percent of the ship’s components sourced from Indian suppliers. The Ministry of Defence announced that the project will create 3,000 direct jobs and 10,000 indirect jobs in the shipbuilding sector.
