INDIA —India’s Ministry of Defence (MoD) has signed a INR 4.99 billion contract with Cochin Shipyard for the normal refit and re-powering of INS Betwa, a Brahmaputra-class guided-missile frigate operated by the Indian Navy. The project will involve a substantial modification of the vessel’s propulsion architecture, alongside upgrades to its onboard combat systems.
A central component of the programme is the replacement of INS Betwa’s existing steam-based propulsion arrangement with a diesel-engine-based system. This will require complex engineering and integration work within the vessel’s existing platform. The refit will also include the installation of a modernised weapons suite intended to strengthen the frigate’s combat capabilities and operational effectiveness.
The propulsion conversion is particularly significant for India's naval maintenance sector, as it involves more than routine servicing or equipment replacement. Executing such a transformation requires specialised shipyard infrastructure, engineering expertise, machinery integration and extensive testing. The programme is expected to strengthen domestic capabilities in maintaining and upgrading existing naval vessels, reducing dependence on external support for complex ship repair requirements.
The contract is also expected to involve more than 50 micro, small and medium enterprises (MSMEs), creating business opportunities across the domestic shipbuilding supply chain. Participating suppliers and ancillary manufacturers could benefit from demand for engineering components, equipment, fabrication, electrical systems and associated technical services. The project is therefore expected to generate employment and support industrial activity beyond the primary shipyard.
Cochin Shipyard is a government-owned shipbuilding and ship repair enterprise headquartered in Kochi, Kerala, with capabilities spanning commercial and defence vessel construction, maintenance and refurbishment. The Ministry of Defence is India's central government department responsible for defence policy, military administration and procurement.
The agreement was signed in New Delhi in the presence of Defence Secretary Rajesh Kumar Singh. For the Indian Navy, the programme represents an investment in extending and improving the capabilities of an existing frontline platform rather than acquiring an entirely new vessel. For India's defence industrial base, it creates an opportunity to develop specialised expertise in propulsion conversion and complex naval platform modernisation, potentially supporting similar maintenance and upgrade requirements across the fleet.
