Focus: GS III- Defence

Why in News?

Recently, the Defence Minister of India launched Y- 3023 Dunagiri, a Project 17A frigate built by Garden Reach Shipbuilders Limited (GRSE) in Kolkata.

About Y-3023

  • The fourth ship of the Project 17A Frigates is named “Dunagiri.”
  • It bears the name of a mountain range in Uttarakhand.
  • “Dunagiri” is the reincarnation of the former “Dunagiri,” a Leander Class ASW Frigate that served for 33 years and took part in a number of difficult operations and international training exercises.

The first three ships under Project 17A were:

  • INS Nilgiri
  • INS Himgiri
  • INS Udaygiri

About Project 17A Frigates

  • Project 17A frigates are follow-on of the P17 Frigates (Shivalik Class) with improved stealth features, advanced weapons and sensors and platform management systems.
  • There will be seven frigates built under P-17 A for the Indian Navy which will be equipped with advanced stealth capability, four at Mazagon Dock Shipbuilders (MDL), Mumbai and three at Garden Reach Ship Builders Limited (GRSE), Kolkata.


  • The main advanced stealth features of P-17A pertain to the smaller Radar cross-section of the ship achieved through the use of a special super structure shape which reduces radar wave reflections.
  • The P17A frigates incorporate new design concepts for improved survivability, sea keeping, stealth and ship manoeuvrability.
  • Another important feature is regarding the ship’s low acoustic noise emanating from propellers, operating machinery like Diesel Generators etc., which helps sonars on other ships to detect its presence.
  • Such stealth features play an important role in improving the ship’s survivability in any hostile environment during operations.
  • The main weapon and sensor suite of P-17A ships indicated are BrahMos SSM, LRSAM (Forward & Aft configuration) with MF STAR radar, indigenous Sonar, and Triple tube Heavy Torpedo launcher.
