India’s naval strength has received a notable boost with the induction of three indigenously built vessels—INS Dunagiri, INS Sanshodhak, and INS Agray—constructed by Garden Reach Shipbuilding and Engineers Ltd in Kolkata. This development reflects a steady shift towards self-reliance in defence manufacturing while enhancing the Navy’s capabilities across combat, surveillance, and anti-submarine operations.
INS Dunagiri, a Nilgiri-class (Project 17A) stealth frigate, represents a significant advancement in naval warfare technology. Designed as a multi-mission warship, it is equipped with sophisticated systems including BrahMos missiles, torpedoes, and rocket launchers. Its stealth features reduce radar visibility, while improved automation and survivability make it more efficient in modern combat scenarios. The vessel also carries forward the legacy of the earlier INS Dunagiri, blending historical significance with cutting-edge capability.
INS Sanshodhak, a Survey Vessel (Large), strengthens the Navy’s hydrographic and oceanographic capabilities. It is designed to conduct detailed mapping of seabeds, port approaches, and coastal waters, which is essential for safe navigation and strategic planning. Equipped with advanced tools such as autonomous underwater vehicles, remotely operated vehicles, and digital sonar systems, the vessel enables precise data collection in both shallow and deep waters, supporting both defence and civilian maritime needs.
INS Agray, part of the Arnala-class anti-submarine warfare shallow water craft programme, enhances the Navy’s ability to detect and respond to underwater threats, particularly in coastal regions. Its specialised design allows for effective surveillance and tracking of submarines in shallow waters, an area where detection is typically more challenging. By strengthening coastal defence and underwater monitoring, the vessel adds a critical layer to India’s maritime security framework.
Together, these three ships highlight the growing strength of India’s domestic shipbuilding ecosystem and its focus on reducing dependence on imports. Their induction not only improves operational readiness but also underscores a broader strategic push towards indigenisation, technological advancement, and a more resilient naval infrastructure capable of addressing evolving maritime challenges.
