Prime Minister Narendra Modi has commissioned three indigenously designed and built naval ships in a major boost to India’s maritime capabilities. The announcements underscore India’s push toward stronger self-reliance in defence manufacturing and signal the Navy’s expanding role in surveillance, undersea operations, and coastal defence.
The first ship commissioned is INS Dunagiri, described as an advanced stealth frigate. As a stealth-focused platform, INS Dunagiri is expected to enhance the Indian Navy’s ability to operate with reduced detectability, supporting modern naval missions that require survivability in contested environments. Frigates of this class typically serve as versatile warships capable of escort duties, air and surface surveillance coordination, and general surface warfare operations, while stealth features can improve operational effectiveness during both peacetime patrols and higher-intensity scenarios.
The second vessel is INS Sanshodhak, a large survey ship. Unlike combat-oriented warships, survey vessels are primarily designed to support mapping and data collection for naval and scientific missions. Such ships play a critical role in maritime domain awareness by conducting hydrographic, oceanographic, and geospatial surveys. The information gathered by survey platforms can improve navigation safety, support submarine and surface route planning, and contribute to broader strategic understanding of sea conditions, seabed characteristics, and underwater terrain.
By commissioning INS Sanshodhak alongside a stealth frigate, the Navy gains a complementary capability set—pairing platforms that can conduct high-end operations with platforms that supply the knowledge needed to plan and execute missions effectively. This combination is particularly important as naval forces increasingly rely on high-quality data for undersea navigation, targeting accuracy, and risk reduction.
The third commissioned craft is INS Agray, an anti-submarine warfare shallow water craft. This ship type is tailored to address threats from submarines in coastal and shallow maritime environments, where many anti-submarine operations can be more challenging due to cluttered underwater conditions and constrained operating spaces. Shallow water anti-submarine platforms are designed to detect and counter underwater threats near coastlines and in littoral regions—areas that are strategically significant for trade routes, naval access, and territorial security.
INS Agray’s commissioning reflects an emphasis on improving the Navy’s layered defence approach. Submarine threats can emerge from both foreign and regional actors, and effective anti-submarine warfare requires specialized assets that can operate where conventional deep-water systems may be less effective. By adding a shallow water anti-submarine craft to the fleet, India enhances its readiness to respond to underwater challenges closer to shore, expanding the operational coverage of the Navy.
Taken together, the commissioning of INS Dunagiri, INS Sanshodhak, and INS Agray represents a broad advancement across multiple mission categories: stealth and surface combat readiness through the frigate, undersea and maritime mapping support through the survey vessel, and targeted coastal anti-submarine capability through the shallow water craft. The three ships also highlight the continued focus on indigenous defence production, signalling that India is building warships and naval support platforms domestically rather than relying primarily on imports.
Beyond the individual capabilities of each ship, the event is also significant for the broader strategic message it sends. Modern navies must balance deterrence, intelligence and surveillance, and operational flexibility. Commissioning assets that address detection and survivability (INS Dunagiri), knowledge generation and route safety (INS Sanshodhak), and localized undersea threat response (INS Agray) suggests an integrated modernization path.
The news framing indicates that these vessels are designed and built with India’s own capabilities, and their induction into service is expected to strengthen the Indian Navy’s ability to protect maritime interests across different environments. With survey capacity, stealth combat capability, and specialized anti-submarine function in shallow waters, the fleet’s overall readiness and mission effectiveness are likely to improve.
