INS Dunagiri Delivered as Fifth Nilgiri Class Frigate

The Indian Navy has received INS Dunagiri, the fifth stealth frigate under the Nilgiri-class (Project 17A), marking a major advancement in indigenous warship construction. The induction strengthens India’s maritime capabilities and highlights progress in self-reliant defence manufacturing.

Overview of INS Dunagiri

INS Dunagiri is the fifth ship of the Nilgiri-class frigates under Project 17A. It has been designed by the Warship Design Bureau and constructed by Garden Reach Shipbuilding and Engineers Limited (GRSE), Kolkata. The vessel is a modern reincarnation of the earlier INS Dunagiri, a Leander-class frigate that served in the Indian Navy, symbolising continuity and technological advancement.

Design and Propulsion System

The ship is equipped with a Combined Diesel or Gas (CODOG) propulsion system, integrating both diesel engines and gas turbines. This configuration allows efficient cruising at lower speeds using diesel engines and high-speed operations using gas turbines. It features controllable pitch propellers and an advanced Integrated Platform Management System, ensuring enhanced operational efficiency and automation.

Advanced Weapon Systems

INS Dunagiri is fitted with a comprehensive suite of modern weaponry. It includes BrahMos surface-to-surface missiles, MF-STAR radar, and the MRSAM air defence system. Additionally, the ship is armed with a 76 mm Super Rapid Gun Mount, close-in weapon systems, and anti-submarine warfare capabilities such as rockets and torpedoes. These systems enable multi-dimensional combat operations across air, surface, and subsurface domains.

Important Facts for Exams

• Project 17A focuses on stealth frigates with advanced features and indigenous design.
• CODOG propulsion combines diesel engines and gas turbines for flexibility.
• BrahMos is a supersonic cruise missile jointly developed by India and Russia.
• MRSAM is used for medium-range surface-to-air defence.

Strategic Importance for Indian Navy

The induction of INS Dunagiri enhances the Indian Navy’s blue-water capabilities and strengthens maritime security in the Indian Ocean Region. It reflects India’s growing expertise in advanced naval shipbuilding and supports the broader objective of self-reliance in defence. The frigate will play a key role in safeguarding sea lanes, conducting surveillance, and participating in multi-domain naval operations.
