Indian Navy gets 3 deadly ships in a single day, equipped with Brahmos

These include two warships (including a stealth frigate) and a large survey ship. The names of the three ships are Dunagiri, Agreya and Mohodak

Key Features of the 3 Ships

1. Dunagiri (Stealth Frigate)

This is the fifth Nilgiri-class frigate built under Project 17A to be commissioned into the Navy in the last 16 months. Defence Minister Rajnath Singh launched the project at GRSE in Kolkata on July 15, 2022. It is a 149-metre long, 6,670-tonne guided-missile frigate.

In terms of combat capability, the BrahMos is equipped with anti-ship and land-attack cruise missiles along with advanced defence systems. It is capable of carrying out multi-dimensional operations in the air, surface and underwater.

Designed by the Warship Design Bureau, the ship uses 75% indigenous materials and involves over 200 MSMEs. Based on past experiences, its construction period has been reduced to 80 months as compared to 93 months for Nilgiri.

2. Agreya (Anti-Submarine Warfare Ship)

This is the fourth ship out of eight 'Arnala' class Anti-Submarine Warfare Shallow Water Crafts (ASW-SWCs). Its main purpose is to enhance the Navy's anti-submarine, mine-warfare and coastal surveillance capabilities. This 77-metre long waterjet-powered warship is equipped with state-of-the-art lightweight torpedoes, indigenous rocket launchers and SONAR. In line with the vision of 'Atmanirbhar Bharat', it uses over 80% indigenous materials.

3. Surveyor (Large Survey Vessel)

The Surveyor is a large survey vessel designed for coastal and deep-water hydrographic surveys. Its displacement is about 3,400 tons and its overall length is 110 meters. Its main function is to survey harbor passages and accurately determine navigational routes (sea lanes). In addition, it will also collect oceanographic and geophysical data for defense and civil use.

These are equipped with state-of-the-art hydrographic equipment such as data acquisition systems, autonomous underwater vehicles (AUVs), remotely operated vehicles (ROVs), DGPS long-range positioning systems and digital side scan sonar. The ship is part of a contract for four survey ships signed on 30 October 2018. The previous three ships of the same class - INS Sandhyak, INS Nitshak and INS Eekshak - were commissioned in February 2024, December 2024 and November 2025 respectively. These ships also use more than 80% indigenous materials in terms of cost.
