Context: Recently, the Indian Navy commissioned INS Taragiri at Visakhapatnam, marking a major step in enhancing India’s maritime power, self-reliance, and Indo-Pacific security presence. 

About INS Taragiri

• INS Taragiri is the fourth Nilgiri-class (Project 17A) stealth guided-missile frigate. 

• It is part of a 7-ship Project 17A programme, with 4 built by Mazagon Dock Shipbuilders Limited and 3 by GRSE. 

• It is designated as F41 and inducted into the Eastern Fleet under the Eastern Naval Command. 

• It is named after the Taragiri hills in Uttarakhand. 

• It carries forward the legacy of the Leander-class INS Taragiri (1980–2013). 

• Its motto is “Rise Above.” 

• Construction & Indigenous Ecosystem:

• The ship has a displacement of approximately 6,670 tonnes. 
• It was built in about 15% less time compared to earlier ships. 
• It has more than 75% indigenous content with contributions from over 200 MSMEs. 
• It reflects a strong public-private partnership and supports thousands of jobs. 

• Design & Advanced Technology:

• It represents a generational upgrade over Shivalik-class frigates. 
• It incorporates stealth features with reduced radar, acoustic, and infrared signatures. 
• It is powered by a CODOG (Combined Diesel or Gas) propulsion system. 
• It can achieve high speeds of around 30 knots along with long endurance. 
• It is equipped with a Combat Management System (CMS) for real-time threat response. 
• It includes an Integrated Platform Management System (IPMS) for centralised control of machinery and power. 

• Combat Capabilities:

• It is equipped with BrahMos supersonic missiles for surface strike capability. 
• It uses the MRSAM/Barak system along with MF-STAR radar for air defence. 
• It is fitted with HUMSA sonar for anti-submarine warfare. 
• It carries torpedoes and ERASR (Extended Range Anti-Submarine Rocket). 
• It includes a 76 mm SRGM and close-in weapon systems (30 mm and 12.7 mm guns). 
• It is capable of addressing threats across air, surface, and sub-surface domains. 

• Operational Role & Versatility:

• It can perform carrier battle group escort missions. 
• It is capable of undertaking independent offensive operations. 
• It supports maritime surveillance and anti-piracy missions. 
• It can conduct coastal security operations. 
• It is suitable for Humanitarian Assistance and Disaster Relief (HADR) operations. 
• It can operate helicopters such as Kamov and MH-60R. 
• It can remain deployed at sea for extended durations. 

• Unique Features & Utility:

• It generates approximately 4 MW of power, enough to support around 8,000 homes during disasters. 
• Its indigenous systems enable faster maintenance and reduced downtime. 
• It is operated by around 300 personnel, including provision for women officers and sailors.

Significance

• Maritime Security Imperative: With a ~11,000 km coastline and ~95% of trade via sea, it ensures protection of sea lanes, choke points, energy routes, and undersea communication cables, thereby safeguarding India’s economic and digital infrastructure.

• Strengthening Naval Capability: As a stealth, multi-role warship with advanced sensors, supersonic missiles, and long endurance, it enhances operational reach, combat readiness, surveillance, and rapid response while strengthening presence from the Persian Gulf to the Malacca Strait.

• Aatmanirbhar Bharat in Defence: With over 75% indigenous content and participation of 200+ MSMEs, it reduces import dependence, strengthens the defence industrial ecosystem, reflects strong public-private partnership, and aligns with rising defence exports (~₹38,000+ crore).

• Strategic & Geopolitical Significance: Equipped for multi-domain warfare and deployed in the Eastern Fleet, it acts as a credible deterrent in Indo-Pacific geopolitics, supports India as a net security provider, remains relevant amid tensions like Strait of Hormuz disruptions, and complements naval modernisation including INS Aridhaman.

• Multi-Dimensional Role: Beyond combat, it enables carrier escort operations, anti-piracy missions, maritime surveillance, coastal security, disaster relief, evacuation missions, and humanitarian assistance, including power support during crises.

• Symbol of Maritime Power & Sovereignty: It represents Make in India, technological maturity, faster shipbuilding capability, and India’s transition to a self-reliant blue-water navy, reinforcing the vision of Viksit Bharat 2047 and a secure Indo-Pacific.

About the Project 17 & Project 17A (India’s Stealth Frigate Programme)

• Design work for India’s stealth frigates began in the 1990s under Project 17, which later evolved into the more advanced Project 17A programme. 

• Project 17 (Shivalik-Class Frigates): A total of 3 multipurpose stealth frigates were constructed at Mazagon Dock Shipbuilders Limited (Mumbai) between 2001 and 2012.

• The three ships are INS Shivalik (2010), INS Satpura (2011), and INS Sahyadri (2012). 

• Transition to Project 17A: Project 17A was launched as an advanced follow-on to Project 17, focusing on enhanced stealth features, greater automation, and improved combat capabilities.

Construction began in December 2017, five years after the completion of Project 17. 

• Project 17A (Nilgiri-Class Frigates): A total of 7 stealth frigates are being built under this programme, marking a significant expansion in India’s naval capability. 

• The frigates are being constructed at two major shipyards: Mazagon Dock Shipbuilders Limited (4 ships) and Garden Reach Shipbuilders and Engineers (3 ships). 

• INS Nilgiri was commissioned in January 2025, followed by INS Udaygiri and INS Himgiri in 2025.

• INS Taragiri has now been commissioned; INS Dunagiri has already been delivered to the Indian Navy, while the remaining ships—Mahendragiri and Vindhyagiri—are expected to join the fleet by 2026.
