India’s maritime and defence push, from deeper ports to stronger warships, is creating new business opportunities. Two niche players, beyond Mazgon Dock, are well positioned to benefit from this emerging growth cycle.
India’s shipbuilding, maritime and defence sector is entering a capacity-expansion phase, supported by rising cargo movement and ongoing port modernisation. At the same time, the government’s push to strengthen defence manufacturing is creating new opportunities for Indian marine equipment and component suppliers.
The Macro Setup: Inland Waterways and Port Expansion
India aims to increase the share of inland waterways and coastal shipping in freight movement from 6% to 12% by 2047. This shift could drive demand for dredging, port support vessels and shipbuilding. Meanwhile, expanding naval capabilities and a push for defence indigenisation are creating opportunities for domestic manufacturers.
Suppliers of specialised steel, marine components and defence equipment stand to benefit from this shift. The scale of the opportunity is reflected in India’s port infrastructure expansion. Port capacity doubled from 1,400 million tonnes per annum (MTPA) in FY14 to 2,818 MTPA in FY26.
The government aims to raise it further to 3,500 MTPA by 2030, which would be 2.5X the FY14 level. Inland waterway cargo movement has also grown sharply, from 29 million metric tonnes (MMT) in FY15 to 218 MMT in FY26. These developments create two distinct investment opportunities.
The first is in dredging, port vessel operations and shipbuilding. Higher cargo movement and port expansion could increase demand for specialised vessels and maintenance services. The second opportunity lies in defence manufacturing. Naval modernisation and import substitution could benefit domestic suppliers of specialised steel and marine components.
The ₹69,725 crore shipbuilding package further supports domestic manufacturing, shipyard modernisation and maritime financing. Now typically, any study into shipbuilding starts with Mazagon Dock, the largest player in this field. But today, we dig into 2 under-the-radar smallcaps. These are two specialised companies operating in segments that are positioned to benefit from these policy moves. However, their business models, growth drivers and execution risks differ.
