DELIVERY OF MANGROL – THE THIRD ANTI-SUBMARINE WARFARE SHALLOW WATER CRAFT BUILT BY CSL, KOCHI

The delivery of 'Mangrol', the third Anti-Submarine Warfare Shallow Water Craft (ASW SWC), to the Indian Navy on August 21, 2026, by Cochin Shipyard Limited (CSL) represents a significant milestone in India's journey toward self-reliance in defence manufacturing. This achievement must be understood within the broader historical context of India's naval modernization and indigenous shipbuilding programme that traces its roots to the post-independence era. The Indian Navy's shift from being a 'buyer's navy' to a 'builder's navy' began in earnest with the 1960s decision to construct warships domestically, leading to the establishment of Mazagon Dock Shipbuilders Limited (MDL), Garden Reach Shipbuilders & Engineers (GRSE), and the modernization of CSL. The ASW SWC project, approved by the Defence Acquisition Council (DAC) in 2013, envisaged the construction of 16 shallow water craft — 8 each by CSL and GRSE — to replace the aging Abhay-class and Pondicherry-class vessels. The first two ships of this class, 'Mahe' and 'Malvan', were delivered by CSL in 2023 and 2024 respectively, making Mangrol the third in the series. The key stakeholders in this achievement span multiple levels of governance and industry. At the apex, the Ministry of Defence (MoD) under the Defence Procurement Procedure (DPP) 2020 framework provided the policy impetus, with the 'Make in India' and 'Aatmanirbhar Bharat' initiatives serving as guiding philosophies. The Indian Navy, as the end-user, defined the operational requirements through the Staff Qualitative Requirements (SQRs), emphasizing coastal ASW capabilities critical for littoral warfare in the Indian Ocean Region (IOR). CSL, a Miniratna Category-I Central Public Sector Enterprise under the Ministry of Ports, Shipping and Waterways, executed the construction, leveraging its expertise in building complex platforms like the Indigenous Aircraft Carrier INS Vikrant. The project also involved numerous MSMEs and private sector vendors supplying over 80% indigenous content — a figure that directly reflects the DPP's categorization of 'Buy (Indian-IDDM)' (Indigenously Designed, Developed and Manufactured) as the highest priority procurement category. The significance of this delivery extends across multiple dimensions. Strategically, the ASW SWCs address a critical capability gap in India's coastal defence architecture. With the Indian Ocean witnessing increased submarine activity — including extra-regional powers' deployments — the ability to detect, track, and neutralize underwater threats in shallow waters (less than 200 meters depth) is paramount. These ships, with their waterjet propulsion enabling speeds over 25 knots and low acoustic signatures, are tailor-made for operations in the complex littoral environment of the Arabian Sea and Bay of Bengal. Economically, the project exemplifies the defence-industrial ecosystem envisioned under the Defence Production and Export Promotion Policy (DPEPP) 2020, which targets a defence manufacturing turnover of ₹1,75,000 crore (including ₹35,000 crore exports) by 2025. The 80% indigenous content translates to thousands of jobs across the supply chain and technology absorption in areas like sonar systems (developed by DRDO's NPOL), combat management systems, and waterjet propulsion. Politically, it reinforces the government's narrative of strategic autonomy, a principle enshrined in Article 51 of the Constitution (Directive Principles of State Policy) which mandates the State to "promote international peace and security" and "foster respect for international law" — objectives served by a credible, self-reliant defence posture. From a governance perspective, the project illustrates the evolving civil-military-industrial coordination in India. The creation of the Chief of Defence Staff (CDS) and Department of Military Affairs (DMA) in 2019 has streamlined capability development, while the Defence Acquisition Council (DAC) and Defence Procurement Board (DPB) ensure timely decision-making. The naming of the ship after Mangrol, a coastal town in Gujarat's Junagadh district with a historic fishing harbour, and its linkage to the erstwhile INS Mangrol (a Pondicherry-class minesweeper decommissioned in 2004), reflects the Navy's tradition of preserving institutional memory — a practice that strengthens organizational culture and connects contemporary capabilities with historical legacy. Looking ahead, the delivery of Mangrol sets the stage for the remaining vessels in the 16-ship ASW SWC programme, with CSL contracted for five more and GRSE for eight. The timely execution of this project will be a litmus test for India's shipbuilding capacity, especially as CSL simultaneously progresses on the Next Generation Missile Vessels (NGMVs) and the repeat order for the Indigenous Aircraft Carrier (IAC-II). Internationally, successful induction of these platforms could open export avenues to friendly littoral nations in the IOR, aligning with the SAGAR (Security and Growth for All in the Region) doctrine articulated by the Prime Minister in 2015. However, challenges remain: sustaining production rates, managing technology obsolescence, and integrating emerging capabilities like unmanned underwater vehicles (UUVs) and AI-driven sonar processing will require continuous R&D investment. The Defence Technology and Trade Initiative (DTTI) with the US and similar frameworks with France, Russia, and Israel could facilitate technology infusion, but the core imperative remains indigenous innovation — a goal that the Mangrol delivery powerfully symbolizes.
