‘Mahendragiri’ to join Navy fleet; warship combat ready to safeguard our maritime interests: Rajnath
INS Mahendragiri, the sixth and final ship of Project 17A, was commissioned into the Indian Navy on July 11, 2026, at Visakhapatnam
The ceremony was held in the presence of senior naval officials and other dignitaries at the naval dockyard in the Eastern Fleet
The commissioning was described as a milestone in India's indigenous warship construction and defence self-reliance efforts
The ship was delivered to the Navy by its builder in April 2026, ahead of the formal commissioning
With Mahendragiri's induction, the Project 17A stealth frigate programme's ships have all been progressively delivered, joining Nilgiri, Udaygiri, Himgiri, Taragiri, and Dunagiri already in service
Project 17A (Nilgiri-class) Stealth Frigate Programme
Project 17A is the Indian Navy's follow-on stealth frigate programme to Project 17 (Shivalik-class), designed to induct more advanced, more indigenous warships with improved stealth and survivability. It is executed by two public-sector shipyards under the Ministry of Defence's warship-building ecosystem.
Key Details
- The class comprises seven ships in total, named after mountain ranges: Nilgiri, Udaygiri, Himgiri, Taragiri, Dunagiri, Vindhyagiri, and Mahendragiri
- Built across two yards: Mazagon Dock Shipbuilders Limited (MDL), Mumbai, and Garden Reach Shipbuilders & Engineers (GRSE), Kolkata
- Designed in-house by the Indian Navy's Warship Design Bureau (WDB)
- Ships carry more than 75% indigenous content, including indigenous DMR 249A shipbuilding steel, the HUMSA-NG sonar suite, the Shakti electronic warfare suite, and an indigenous Integrated Platform Management System
- Approximate displacement: around 6,670 tonnes, larger than the preceding Project 17 (Shivalik-class) frigates
- Propulsion: Combined Diesel or Gas (CODAG) system
Mahendragiri's commissioning marks the near-completion of the Project 17A programme's induction cycle, following Nilgiri (2025), Udaygiri and Himgiri (2025), Taragiri (2026), and Dunagiri (2026) — making it a key marker of progress in India's indigenous frigate-building capability.
Aatmanirbhar Bharat in Defence Shipbuilding
"Aatmanirbhar Bharat" (self-reliant India) in defence refers to the policy push, formalised through Defence Acquisition Procedure (DAP) reforms, to maximise indigenous design, development, and manufacture of defence platforms, reducing dependence on imports.
Key Details
- Indigenisation is measured as a percentage of indigenous content by value/systems on a platform; Project 17A's 75%+ figure is presented as a benchmark improvement over earlier classes (Project 17/Shivalik-class had lower indigenous content)
- The Defence Acquisition Procedure (DAP) 2020 introduced procurement categories such as Buy (Indian-IDDM), which prioritises Indigenously Designed, Developed and Manufactured platforms
- Warship construction has engaged over 200 Micro, Small and Medium Enterprises (MSMEs) as part of the wider domestic defence-industrial supply chain
- Indigenous weapons and sensors integrated on such platforms typically include BrahMos (surface-to-surface) and Barak-8 (surface-to-air, jointly developed with Israel) missile systems, alongside indigenous combat management and electronic warfare systems
Mahendragiri's high indigenous content and MSME involvement are cited as evidence of the maturing domestic warship-building ecosystem under the broader Aatmanirbhar Bharat push in defence manufacturing.
Naval Force Structure — Fleet Commands and Eastern Fleet
The Indian Navy organises its combat fleet under two operational commands: the Western Naval Command (headquartered at Mumbai, commanding the Western Fleet) and the Eastern Naval Command (headquartered at Visakhapatnam, commanding the Eastern Fleet).
Key Details
- Visakhapatnam is the headquarters of the Eastern Naval Command and home port of the Eastern Fleet, which covers the Bay of Bengal and the wider eastern Indian Ocean Region
- Frigates like Mahendragiri are principal surface combatants providing anti-air, anti-surface, and anti-submarine warfare capability, distinct from larger destroyers (e.g., Project 15B/Visakhapatnam-class) and smaller corvettes (e.g., Kamorta-class)
- Such ships also perform non-combat roles: maritime security, humanitarian assistance and disaster relief (HADR), search and rescue, and sustained presence missions across the Indian Ocean Region
Mahendragiri's induction into the Eastern Fleet strengthens the Navy's surface combat capability in the Bay of Bengal, a region of growing strategic significance given India's Indo-Pacific and Act East priorities.
