Garden Reach Shipbuilders and Engineers (GRSE) has launched Yard 3034 (named Ajay), the final vessel in the anti-submarine warfare shallow water craft (ASW SWC) series built for the Indian Navy at its facility in Kolkata, India.
The addition of this warship, which took place on 21 July 2025, will enhance the Indian Navy’s capabilities in underwater surveillance, anti-submarine warfare and mine-laying operations.

Yard 3034 is outfitted with sensors including a hull mounted sonar and a low frequency variable depth sonar.
The ship’s armaments consist of advanced torpedoes, anti-submarine rockets, an NSG-30 gun, and a 12.7 mm SRCG for offensive firepower. Propulsion for the ship comes from diesel engines coupled with waterjets for manoeuvrability.
The Indian Ministry of Defence (MoD) said in a statement: “The launch of Ajay is a significant milestone in the Indian Navy’s continued quest for self-reliance in shipbuilding, weapons, sensors and advanced communication, and electronic warfare systems.”
“With an indigenous content of over 80%, the ship exemplifies the government of India’s initiative of Aatmanirbhar Bharat and Make in India and will provide significant capabilities to secure our national maritime interests in the Indian Ocean region.”

By GlobalDataThis follows the commissioning of Arnala, the first of eight ships in the class, on 18 June 2025 with plans to deliver the second vessel in August.
INS Arnala was delivered in May.
The ASW SWC vessels have been built by GRSE via a public-private partnership with L&T Shipyard.
In April 2019, the MoD finalised agreements with GRSE and Cochin Shipyard Limited (CSL) to produce eight ASW SWC ships each, as part of the Make in India initiative.
The ships built by GRSE are classified as Arnala-class, while those from CSL bear the Mahe-class designation. These ASW SWC ships will succeed the Indian Navy’s Abhay-class corvettes, which have been operational since 1989.
