Why in News?

Recently, Mazagon Dock Shipbuilders Ltd (MDL), which is under the Ministry of Defence, launched Taragiri, the third stealth frigate of Project 17A.

What is Project 17A?

  • About:
    • Project 17 Alpha frigates (P-17A) were launched by the Indian Navy in 2019 to construct a series of stealth guided-missile frigates.
    • These 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.
    • The first stealth ship launched under Project 17A was the Nilgiri, which was launched in 2019.
    • Udaygiri, the second ship, was launched in May 2022, and will likely be commissioned in 2024.
  • Present Status: Further, seven P17A Frigates are under various stages of construction at MDL and GRSE.
  • Benefits:
    • It provides additional benefits such as economic development, and employment generation for Indian Shipyards, their sub-contractors and the ancillary industry.
    • Around 75% of the orders of Project 17A have been placed on indigenous firms including MSMEs, thus reinforcing the country’s quest for Atma Nirbhar Bharat.
      • Indigenous construction of complex frontline ships such as Stealth Frigates has catapulted the nation to a higher pedestal in the arena of shipbuilding.

What are the Key Highlights of Taragiri?

  • Taragiri is named after a hill range in the Himalayas located at Garhwal.
  • The ship has been built using an integrated construction methodology which involves hull block construction in different geographical locations.
  • The ship will have state-of-the-art weapons, sensors, an advanced action information system, an integrated platform management system, world-class modular living spaces, a sophisticated power distribution system and a host of other advanced features.
  • It will be fitted with a 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.

  • The design of the Astradharini was a collaborative effort of Naval Science and Technological Laboratory (NSTL), Shoft Shipyard and IIT Kharagpur.
  • It is an advanced replacement for Astravahini which was decommissioned on 17th July 2015.
  • It has a unique design of a catamaran hull form that significantly reduces its power requirement and is built with indigenous steel.
  • It can operate at high sea states and has a large deck area with Torpedo Launchers for deploying and recovering various kinds of Torpedos during the trials.
  • The ship also has modern power generation and distribution, navigation and communication systems.
  • 95% of the systems of the ship are of indigenous design, thus demonstrating the Navy’s continued adherence to the ‘Make in India’ philosophy.
  • INS Astradharini will be used to carry out the technical trials of underwater weapons and systems developed by NSTL, a naval systems laboratory of DRDO. Therefore, option (c) is the correct answer.
