1. Commissioning of INS Anjadip: Strategic Context

INS Anjadip was commissioned on February 27, 2026, at Chennai Port by the Chief of the Naval Staff, Admiral Dinesh K. Tripathi. It is the third of eight vessels being constructed under the Anti-Submarine Warfare Shallow Water Craft (ASW-SWC) project. The ship took approximately 4 years and 2 months to complete, reflecting the growing pace of indigenous naval shipbuilding.

The Ministry of Defence signed the contract with Garden Reach Shipbuilders & Engineers (GRSE) on April 29, 2019. Keel laying commenced on June 17, 2022, at Kattupalli shipyard, and the vessel was launched on June 13, 2023. This timeline demonstrates the structured phases of modern naval shipbuilding—contracting, keel laying, launch, and commissioning.

The commissioning of INS Anjadip comes at a time when India faces increasing maritime security challenges in the Indian Ocean Region (IOR), including submarine proliferation and expanding naval footprints of extra-regional powers. Enhancing shallow-water anti-submarine capability is therefore critical for coastal defence and sea denial.

The induction of specialised ASW vessels strengthens India’s layered maritime security architecture. Without dedicated shallow-water platforms, coastal zones remain vulnerable to stealth submarines, potentially undermining deterrence and maritime sovereignty.

2. Technical Features and Combat Capabilities

INS Anjadip is a 77-metre-long shallow water craft equipped with an indigenous Anti-Submarine Warfare (ASW) weapons and sensor package. It includes the Hull Mounted Sonar (HMS) Abhay, Lightweight Torpedoes, and ASW Rockets, designed for detecting and neutralising underwater threats.

The ship uses a high-speed water-jet propulsion system, enabling speeds up to 25 knots. This propulsion system enhances manoeuvrability and stealth, particularly in noisy and shallow coastal waters where traditional large destroyers face operational constraints.

Designed specifically for the littoral combat environment, the vessel can eliminate background noise and detect “silent” diesel-electric or midget submarines hiding in shallow seabeds. In addition to ASW roles, it is capable of coastal surveillance, Low-Intensity Maritime Operations (LIMO), and Search and Rescue (SAR).

Key Features:

  • Length: 77 metres
  • Speed: 25 knots
  • Propulsion: Water-jet system
  • Sonar: Indigenous Hull Mounted Sonar Abhay
  • Armament: Lightweight Torpedoes and ASW Rockets

Technological specialization in shallow-water ASW fills a critical operational gap. If coastal detection capacity remains weak, adversarial submarines can exploit littoral vulnerabilities, threatening ports, sea lanes, and critical maritime infrastructure.

3. Why “Dolphin Hunter”? Operational Significance

INS Anjadip is nicknamed the “Dolphin Hunter” due to its specialised sonar capabilities that function on acoustic principles similar to dolphins. The Hull Mounted Sonar Abhay enables detection, tracking, and neutralisation of enemy submarines in complex coastal waters.

Unlike large destroyers that struggle in noisy littoral environments, this vessel is engineered for stealth operations in near-shore areas. Its ability to filter background noise enhances detection of low-signature diesel-electric submarines.

The water-jet propulsion further increases manoeuvrability, enabling the ship to “weave” through compact coastal corridors effectively. This agility is crucial in safeguarding high-traffic maritime zones such as Tamil Nadu and Puducherry coastlines.

Specialised platforms tailored for littoral warfare enhance operational efficiency and resource optimisation. Ignoring the distinct operational demands of shallow waters could dilute overall naval preparedness.

4. Strategic and Historical Significance of the Name “Anjadip”

The ship is named after Anjadip Island off Karwar in north Karnataka. The name carries historical resonance as the island witnessed decisive naval action during Operation Chutney (December 1961), which contributed to the liberation of Goa.

Admiral Tripathi emphasised that the name reflects “resolve, valour, bold action and safeguarding national maritime interests.” It also marks INS Anjadip as the successor to the last of the Petya-class corvettes, which served from 1972 to 2003.

“That spirit of resolve, valour, bold action and safeguarding national maritime interests at any cost— is the enduring legacy that this Anjadip carries forward.” — Admiral Dinesh K. Tripathi

Naming conventions in naval tradition often reinforce institutional memory and continuity, linking modern platforms to historical missions and national milestones.

Symbolism in defence institutions fosters morale, continuity, and strategic culture. Without such institutional memory, armed forces risk weakening the intangible elements of cohesion and identity.

5. India’s Naval Strength and Modernisation Trajectory

As of February 2026, the Indian Navy operates approximately 145–150 commissioned ships and submarines, though the number fluctuates due to commissioning and decommissioning cycles.

In a significant development, the Navy is on track to commission 19 warships in 2026, marking the highest number in its history. This indicates a strong push toward maritime modernisation amid evolving security dynamics in the Indo-Pacific.

The ASW-SWC project aligns with India’s broader maritime strategy, including coastal security post-26/11, blue water aspirations, and maintaining credible deterrence in the Indian Ocean Region.

Modernisation Indicators:

  • Fleet strength: 145–150 vessels
  • Planned commissioning in 2026: 19 warships (record high)

Fleet expansion combined with capability specialisation enhances sea control, sea denial, and deterrence. If modernisation slows amid rising regional naval competition, India’s maritime leverage in the Indo-Pacific could weaken.

6. Governance and Strategic Implications

The construction of INS Anjadip by GRSE, Kolkata, underscores the role of indigenous shipyards in defence production. It reflects alignment with self-reliance objectives and domestic capacity building in high-technology sectors.

Enhanced ASW capabilities strengthen:

  • Coastal security architecture
  • Protection of Sea Lines of Communication (SLOCs)
  • Maritime domain awareness
  • Deterrence against submarine incursions

Given increasing submarine activity in the Indian Ocean Region, especially by extra-regional powers, shallow-water ASW platforms are central to India’s layered maritime defence doctrine.

Strengthening indigenous maritime capabilities reduces external dependence and enhances strategic autonomy. Neglecting domestic defence manufacturing would increase vulnerability in times of geopolitical stress.

Conclusion

INS Anjadip represents a critical step in strengthening India’s anti-submarine and coastal defence capabilities. By combining indigenous technology, specialised littoral design, and historical symbolism, it reflects both operational readiness and strategic continuity.

As India expands its naval fleet and deepens its role in the Indo-Pacific, sustained investment in specialised platforms like ASW shallow water crafts will be essential to safeguard maritime interests, ensure credible deterrence, and reinforce strategic autonomy in the long term.

Quick Q&A

Everything you need to know

The commissioning of INS Anjadip marks a critical step in strengthening India’s anti-submarine warfare (ASW) and coastal defence capabilities. As the third vessel under the ASW Shallow Water Craft project, it is specifically designed to operate in littoral (near-shore) waters, where conventional large destroyers and frigates face operational constraints due to shallow depths and high acoustic noise. Given India’s vast coastline of over 7,500 km and critical maritime assets along the eastern and western seaboards, such platforms are essential for safeguarding maritime security.

Strategically, shallow water crafts address emerging threats from diesel-electric and midget submarines, which are difficult to detect in coastal environments. The increasing submarine presence in the Indian Ocean Region (IOR), including extra-regional naval deployments, has heightened the importance of undersea domain awareness. INS Anjadip’s induction reflects India’s shift toward strengthening coastal defence layers as part of a broader maritime security architecture.

Thus, beyond adding a single warship, INS Anjadip enhances India’s deterrence posture, improves sea denial capabilities in coastal waters, and aligns with the doctrine of securing the primary area of interest in the Indian Ocean.

Littoral combat capabilities have gained importance because modern naval threats are increasingly shifting toward asymmetric and stealth-based warfare. Coastal regions are economically vital, hosting ports, refineries, nuclear installations, and sea lanes of communication. Submarines operating in shallow waters can exploit acoustic clutter and seabed conditions to remain undetected, posing significant risks to maritime infrastructure.

India’s experience after the 26/11 Mumbai attacks underscored vulnerabilities along the coastline. Since then, the Navy and Coast Guard have prioritised coastal surveillance, maritime domain awareness, and rapid-response capabilities. Vessels like INS Anjadip are equipped with hull-mounted sonar systems such as Abhay and lightweight torpedoes, enabling them to detect and neutralise underwater threats efficiently.

Moreover, the Indo-Pacific’s evolving geopolitics, including increased submarine deployments by regional and extra-regional powers, necessitate robust near-shore defence. Littoral combat platforms ensure layered maritime security—bridging the operational gap between blue-water combatants and coastal patrol vessels.

INS Anjadip incorporates a state-of-the-art indigenous ASW weapons and sensor package, including the Hull Mounted Sonar (HMS) Abhay. This sonar system uses acoustic principles similar to dolphin echolocation, allowing the vessel to detect subtle underwater signatures in noisy coastal waters. Such technology is critical for tracking ‘silent’ diesel-electric submarines that operate close to the seabed.

The ship is armed with lightweight torpedoes and ASW rockets, providing offensive capability once a submarine threat is identified. Additionally, its high-speed water-jet propulsion system enables speeds of up to 25 knots and superior manoeuvrability, essential for rapid interception in constrained coastal corridors.

Unlike large destroyers, which are optimised for blue-water operations, INS Anjadip is engineered for shallow-water stealth operations. This specialised design enhances India’s undersea surveillance grid and contributes to a comprehensive maritime security framework.

INS Anjadip was built by Garden Reach Shipbuilders & Engineers (GRSE), reflecting India’s push toward defence indigenisation under the ‘Aatmanirbhar Bharat’ initiative. Indigenous shipbuilding reduces dependence on foreign suppliers, ensures supply chain resilience, and fosters technological self-reliance. The four-year construction cycle demonstrates growing domestic capability in complex naval platforms.

Advantages include:

  • Strategic autonomy in defence procurement.
  • Employment generation and technological spillovers.
  • Reduced long-term maintenance and lifecycle costs.
However, challenges persist, including delays, cost overruns, and technological gaps in advanced propulsion and sensor systems.

Overall, indigenisation strengthens India’s maritime posture while supporting economic and industrial growth. Sustained investment in research, public-private partnerships, and export promotion can transform India into a regional naval shipbuilding hub.

The name ‘Anjadip’ draws from an island near Karwar that witnessed decisive naval action during Operation Chutney (1961), which contributed to the liberation of Goa. By naming the vessel after this island, the Navy symbolically connects contemporary maritime security to its historical legacy of bold action and territorial integrity.

Such naming traditions serve multiple purposes. They preserve institutional memory, inspire personnel with a sense of continuity, and reinforce national maritime consciousness. Admiral Dinesh K. Tripathi’s reference to Anjadip as a successor to the Petya-class corvette further underlines this continuity of service and operational excellence.

In strategic terms, the symbolism underscores India’s resolve to safeguard maritime interests. Naval platforms thus function not only as military assets but also as carriers of historical identity and strategic messaging.

Commissioning 19 warships in a single year represents an unprecedented expansion of naval capability. With an existing fleet of approximately 145–150 vessels, such additions significantly enhance force levels, enabling better coverage across the Arabian Sea, Bay of Bengal, and wider Indo-Pacific.

From a doctrinal perspective, this expansion supports India’s transition from a primarily defensive maritime posture to a blue-water navy capable of sustained deployments. It strengthens sea control, sea denial, and power projection capabilities while ensuring robust coastal defence through platforms like INS Anjadip.

Regionally, enhanced naval strength bolsters India’s credibility as a net security provider in the Indian Ocean Region. It also strengthens strategic partnerships under frameworks like QUAD and SAGAR (Security and Growth for All in the Region). However, sustaining operational readiness and managing budgetary constraints will remain key challenges in translating numerical growth into effective maritime power.
