GRSE Launches Final Anti-Submarine Warfare Ship ‘INS Ajay’ and Completes ₹6,311 Cr ASW-SWC Project for Indian Navy.

Defence | Dated: 22 Jul 2025

To strengthen India’s coastal and underwater maritime defence infrastructure, Garden Reach Shipbuilders & Engineers (GRSE) Ltd, a Defence Public Sector Undertaking (DPSU) under the Ministry of Defence (MoD), recently launched ‘INS Ajay’, the 8th and final ship in the Arnala-class Anti-Submarine Warfare Shallow Water Craft (ASW-SWC) series, at GRSE’s shipyard in Kolkata, West Bengal.

🎯 Key Highlights:

  • - INS Ajay was ceremonially launched by Priya Deshmukh, the wife of Vice Admiral Kiran Deshmukh, who currently serves as the Chief of Materiel (COM) of the Indian Navy. This launch marks the completion of the construction phase of the 8 ASW-SWC ships being built by GRSE under a landmark April 2019 contract with the MoD, valued at ₹6,311 crore.
  • - The ASW-SWC project was approved to replace the aging Abhay-class corvettes with more modern shallow water anti-submarine patrol vessels. These ships are specially designed for operations in coastal waters and are equipped with high-end sonar systems, lightweight torpedoes, ASW rocket launchers, and Close-In Weapon Systems (CIWS) for superior underwater detection and engagement.
  • - INS Ajay, designated with Pennant Number P34 and Yard Number 3034, is a 77.6-meter-long, 10.5-meter-wide stealth-enabled warship, optimized for full-spectrum underwater surveillance, anti-submarine missions, and coastal patrol duties. It represents a significant boost to India's shallow water combat readiness and coastal security grid.
