COMMISSIONING OF INS ANJADIP AT CHENNAI

1. At a Glance

• INS Anjadip is the fourth ship of the Anti-Submarine Warfare Shallow Water Craft (ASW-SWC) project, commissioned into the Indian Navy at Chennai Port on 27 Feb 2026 [S1].
• Built by Garden Reach Shipbuilders & Engineers (GRSE), Kolkata, with construction support from L&T Shipbuilding, Kattupalli [S1][S2].
• Symbolises Aatmanirbhar Bharat in defence shipbuilding — over 80% indigenous content, hull steel from SAIL [S3].
• UPSC relevance: GS-III (Internal Security, Indigenisation of Defence Tech, Coastal Security).

2. Why in the News

• Commissioning ceremony held at Chennai Port on 27 Feb 2026, presided over by Admiral Dinesh K Tripathi, Chief of the Naval Staff (CNS), hosted by Vice Admiral Sanjay Bhalla, FOC-in-C Eastern Naval Command [S1].

3. Background & Evolution

• Contract signed: MoD & GRSE Kolkata on 29 Apr 2019 for eight ASW-SWC ships — 4 at GRSE, 4 sub-contracted to L&T Kattupalli [S2].
• Anjadip launched: 13 Jun 2023 at L&T Kattupalli [S2].
• Delivered to Navy: 22 Dec 2025 at Chennai [S2].
• Class lineage: ASW-SWC = Arnala-class corvettes, designed to replace the ageing Abhay-class ASW corvettes (Soviet-origin Pauk-II) [S3].
• Predecessors commissioned: INS Arnala and INS Androth preceded Anjadip in the class [S3].
• Name lineage: erstwhile INS Anjadip (named after Anjadip Island off Karwar) — former COs of the old ship attended the ceremony [S1].

4. Core Static Facts

• Project: ASW-SWC (Anti-Submarine Warfare Shallow Water Craft) [S1].
• Class: Arnala-class corvettes [S3].
• Builder: GRSE, Kolkata (lead yard); built at L&T Shipbuilding, Kattupalli (Tamil Nadu) [S1][S2].
• Parent Ministry: Ministry of Defence; operating service: Indian Navy (Eastern Naval Command) [S1].
• Length: ~77 metres — largest Indian naval warships propelled by waterjets [S2].
• Indigenous content: >80%; hull steel — DMR-grade special steel from SAIL [S2][S3].
• Armament: lightweight torpedoes, indigenously designed anti-submarine rockets, shallow-water SONAR [S2].
• Role: anti-submarine ops in coastal waters, Low Intensity Maritime Operations (LIMO), mine-laying, sub-surface surveillance in littoral waters [S3].
• Total contracted: 8 ships under ASW-SWC project [S2].

5. Multi-Dimensional Analysis

Strategic / Security - Plugs critical gap in littoral ASW — countering Chinese & Pakistani submarine activity in India's near-seas and shallow waters where larger destroyers/frigates are inefficient [S3]. - Replaces obsolete Abhay-class ASW corvettes, modernising the Navy's coastal ASW fleet [S3].

Economic / Industrial - Public-private collaboration model: PSU lead-yard (GRSE) sub-contracting to private shipyard (L&T Kattupalli) — template for capacity scaling [S2]. - SAIL supplying entire special-steel requirement reduces import dependency for warship-grade steel [S3].

Scientific / Technological - Waterjet propulsion at 77 m makes these the largest Indian naval ships using waterjets — enables shallow-draft operations [S2]. - Indigenous anti-submarine rockets + shallow-water SONAR reflect maturing DRDO-industry ecosystem [S2].

Administrative / Federal - Builds out Eastern Naval Command (HQ Visakhapatnam) inventory; commissioning at Chennai Port signals deeper integration with Tamil Nadu's defence-industrial corridor [S1].

8. Mains Relevance

• GS-III: Security — Various Security Forces & Agencies and their mandate; Indigenisation of technology and developing new technology.
• GS-II: Governance — Government policies for development in defence sector (Aatmanirbhar Bharat in defence).
• Possible Q stems: 1. "Discuss the strategic significance of Anti-Submarine Warfare Shallow Water Craft (ASW-SWC) in India's coastal defence architecture." 2. "Examine how public–private collaboration in warship construction (PSU shipyards with private partners) is reshaping India's naval indigenisation drive." 3. "Evaluate the role of indigenous content mandates in achieving Aatmanirbharta in defence manufacturing, with reference to recent naval inductions."

10. Common Errors / Trap Areas

• Position in class: Anjadip is the 4th ship of the ASW-SWC project (per commissioning PIB), but 3rd of the GRSE batch — questions may exploit this dual-counting [S1][S2].
• Builder confusion: Lead builder is GRSE Kolkata, but Anjadip was physically built at L&T Kattupalli (Tamil Nadu) under sub-contract — not by L&T as prime [S2].
• Class name: It is the Arnala class, not the "Anjadip class" — first-of-class lends its name [S3].
• Predecessor: Replaces Abhay-class (Soviet Pauk-II derivative), not Khukri or Kora class corvettes [S3].
• Propulsion: Waterjets, not conventional propellers — distinguishing technical feature [S2].
• Anjadip Island lies off Karwar (Karnataka), not in the Andamans [S1].
