This report analyzes the structural asymmetry between the Indian and South Korean shipbuilding industries and the case for converting it into a durable industrial partnership. Indian scale, demand, and demography align with Korean technology, production systems, and institutional depth, and the complementarity is strong enough to support a relationship that goes beyond a commercial transaction. The report separates commercial shipbuilding from naval shipbuilding throughout, because conflating them is the most common error in assessments of Indian capability: India designs and builds destroyers, frigates, and submarines domestically while remaining marginal in large commercial tonnage. It also states the measurement basis for every market-share figure it uses, since gross tonnage, compensated gross tonnage and deadweight tonnage, and orders, completions and orderbook, yield materially different pictures of the same industry.

India carries nearly 95 percent of its trade by volume by sea and builds 0.07 percent of the world’s gross tonnage, ranking fifteenth. Indian-flagged vessels carried about 7.8 percent of its overseas trade in 2018-19, down from 40.7 percent in 1987-88, and payments to foreign carriers approach six lakh crore rupees (USD 68.8 billion) a year. The Union Cabinet approved a 69,725 crore rupee (USD 8.0 billion) package in September 2025, comprising a Shipbuilding Financial Assistance Scheme, a Maritime Development Fund, and a Shipbuilding Development Scheme, alongside five greenfield clusters. Interviews conducted for this report identify the binding constraints as finance, at nine to ten percent against four to eight percent in competitor economies; a thin supplier ecosystem; insufficient large dry docks; import dependence for more than 95 percent of marine engines; and labor productivity rather than labor availability.

South Korea occupies the opposite position and faces the opposite problem. It accounted for 27 percent of world gross tonnage completed in 2025, second globally, supported by roughly 2,700 marine equipment firms supplying about 90 percent of domestic demand. Its shipyard workforce, however, fell 38 percent between 2014 and 2024, from 203,441 to 125,636, amid the world’s lowest fertility rate and a society that crossed the super-aged threshold in December 2024. China took 63 percent of global new orders in compensated gross tonnage in 2025, against Korea’s 21 percent, and Korea’s component trade deficit with China more than tripled in five years.

The report argues that the recent run of agreements, from the Cochin Shipyard and HD KSOE memorandum of July 2025 to the VOYAGES framework, the Thoothukudi mega-shipyard and the workforce plan with KOICA, has created a broad architecture that now requires implementation rather than expansion. Its central caution is that memoranda represent momentum, not outcomes, and the discontinuation of the HD KSOE block fabrication joint venture in August 2026 illustrates this. Sustaining the partnership will require managing a genuine expectations gap, in which Indian participants weigh technology transfer and localization while Korean firms weigh commercial viability, regulatory predictability and managerial autonomy. The report closes with a phased plan across twenty-four months that could be considered by the two governments.
