3rd stealth frigate ‘Taragiri’ launched


Mazagon Dock Shipbuilders Ltd (MDL) recently launched the third Stealth Frigate of Project 17A “Taragiri”.


About Taragiri:

  • Taragiri is the indigenously-designed Nilgiri-class stealth guided-missile frigate constructed by Mazgaon Dock Shipbuilders Limited (MDL).
  • Taragiri is the third stealth frigate built as part of Project 17A under which a series of such guided-missile frigates are being constructed for the Navy.
  • The 149-metre-long and 17.8-metre-wide ship is propelled by a combination of two gas turbines and two main diesel engines which are designed to achieve a speed of more than 28 knots at a displacement of as much as 6,670 tonnes
  • The steel used in the hull construction of P17A frigates is indigenously developed DMR 249A, which is a low carbon micro-alloy grade steel manufactured by the Steel Authority of India Limited. 
  • Construction methodology: This ship has been built using Integrated construction methodology.
    • In this method, several modules of the vessel are pre-constructed and later fitted on the ship.

Important Features

  • Base-design: It has been built with Niligir-like features and has a similar design to the previous two warships.
  • Stealth and modular profile: The two key features of the Taragiri ship are expected to be stealth and modular profile.
  • Undetectable: The vessel has been constructed using composite materials which can decrease its infrared signal and maintain a low radar cross-section, making it almost undetectable.
  • Missile system: It will be fitted with supersonic surface-to-surface missile system.
  • Air defence capability: 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.
  • Gunfire support: Two 30 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.
  • Torpedo and rocket launcher: Indigenously developed triple tube light weight torpedo launchers and rocket launchers will add punch to the ship’s anti-submarine capability.

What is Project 17A of the Indian Navy?

  • Project 17 Alpha frigates (P-17A) were launched by the Indian Navy in 2019.
  • Objective: To construct a series of stealth guided-missile frigates, which are currently being constructed by two companies - Mazagon Dock Shipbuilders (MDL) and Garden Reach Shipbuilders & Engineers (GRSE).
  • These guided-missile frigates have been constructed with a specific stealth design, which has radar-absorbent coatings and is low-observable which can make its approach undetectable for the enemies. The new technology also reduces the infrared signals of the ship.
    • Nilgiri: The first stealth ship launched under Project 17A was launched in 2019 and is expected to be commissioned in the Indian Navy by the end of this year.
    • Udaygiri: The second ship, was launched in May 2022, and likely to be commissioned in 2024.
