The keel of Mahendragiri was laid on 28 June 2022 and the ship is expected to be delivered by February 2026. The vessel is being launched with an approximate launch weight of 3450 Tons.

Project-17A contributes to the prosperity of the Nation by developing the local ecosystem and supporting workforce/entrepreneurs/MSMEs across the economic spectrum. Approximately 210 MSMEs are engaged in this project and approximately 1000 subcontract workforce is working inside MDL premises for this project. Approximately 13 PSUs are contributing to this project in terms of supply of complex equipment and systems. Over 75% of the orders of Project 17A, have been placed on indigenous firms including MSMEs, keeping in line with Government’s vision of “AatmaNirbhar Bharat”.

The ship is designed by the Indian Navy’s in-house design organization viz. Warship Design Bureau. MDL has undertaken the detailed design & construction of the ship which is also overseen by Warship Overseeing Team (Mumbai). The first ship of the Project 17A, ‘Nilgiri’ was launched on 28th Sept 2019 and is being readied for sea trials in the first half of 2024. The total value of the Project 17A is around Rs. 25,700 Crores.

The 149.02 M long & 17.8 M wide ship, propelled by a CODOG combination of two Gas Turbines and 02 Main Diesel Engines which are designed to achieve a speed of over 28 knots at a displacement of approx. 6670 Tons. The steel used in Hull construction of P17A Frigates is indigenously developed DMR 249A which is a low carbon micro alloy grade steel manufactured by SAIL. The indigenously designed ‘Mahendragiri’ will have state-of-the-art weapons, sensors, an advanced action information system, an Integrated Platform Management System, world class modular living spaces, sophisticated power distribution system and a host of other advanced features.  It will be fitted with supersonic surface-to-surface missile system. The ship’s air defence capability, designed to counter the threat of enemy aircraft and anti-ship cruise missiles will revolve around the vertical launch and long range surface to air missile system. Two30 mm rapid-fire guns will provide the ship with close-in-defence capability while an SRGM Gun will enable her to provide effective naval gunfire support. Indigenously developed triple tube light weight torpedo launchers and rocket launchers will add punch to the ship’s anti-submarine capability.

The launch of Mahendragiri is an exemplary testimony of our nation’s Warship building capability and vindicates the fact that MDL has a very rich heritage and legacy in boosting Nation’s blue water prowess.
