What It Is

INS Anjadip is an anti-submarine warfare shallow water craft (ASW-SWC) corvette of the Arnala class, built for the Indian Navy's littoral anti-submarine role. The ASW-SWC series was designed by Garden Reach Shipbuilders & Engineers (GRSE) and is being built in a split across GRSE (Kolkata) and Goa Shipyard Limited (GSL) under the expanded 8-ship shallow-water craft order. Anjadip carries a hull-mounted sonar and an integrated ASW suite — torpedo tubes, ASW rocket launchers and (on later ships) a variable-depth sonar — plus a gun for self-defence, making it a low-cost, shallow-draft complement to the larger Nilgiri-class frigates. The ship is named after the island of Anjadip (Anjediva) off the Karnataka/Goa coast, a historic naval anchor point. Commissioned within the 2024-2026 ASW-SWC induction window, Anjadip is part of the Indian Navy's deliberate build-out of specialist shallow-water ASW capability across both coastal commands, responding to Pakistan's growing submarine fleet and general littoral subsurface threat.

Deployments & Procurement

Anjadip is part of the 8-ship ASW-SWC shallow-water craft programme ordered in 2019 (split across GRSE and GSL). The class lead commissioned in 2024 and subsequent hulls — including Anjadip — have been commissioning through 2025-26. Precise per-hull cost is not uniformly published; the class is broadly reported at ~₹1,500-1,600 crore per ship but values vary by yard and tranche.

FAQ

What is INS Anjadip?

INS Anjadip is an anti-submarine warfare shallow water craft (ASW-SWC) corvette of the Arnala class, built to hunt submarines in India's shallow coastal waters where larger frigates cannot operate effectively.

Sources: [1]

Why is the ship named Anjadip?

Anjadip (Anjediva) is an island off the Goa/Karnataka coast, a historic Portuguese and later Indian naval anchor point, continuing the convention of naming the ASW-SWC class after islands and coastal features.

Sources: [1]

Is Anjadip an indigenous design?

Yes — the ASW-SWC class was designed by Garden Reach Shipbuilders & Engineers (GRSE) and is built in Indian yards. While the hull and much of the combat system are indigenous, sonar transducers, CIWS and propulsion diesels retain some import content.
