The Ministry of Defence has signed a contract worth ₹498.58 crore with Cochin Shipyard Limited (CSL) for normal refit and re-powering of Indian Naval Ship INS Betwa. The agreement was signed in New Delhi today in the presence of Defence Secretary Rajesh Kumar Singh.
The project will see major transformation of the Indian Navy warship’s propulsion system and upgrading its combat capability. It is expected to bolster India’s domestic naval ship repair and maintenance industry.
INS Betwa to Replace Steam Propulsion With Diesel Engines
INS Betwa (Brahmaputra-class frigate) operated by the Indian Navy will get a major propulsion system upgrade under contract.
The existing steam based propulsion system will be replaced by a diesel-engine based one. It is a major change in the ship’s engineering configuration and forms the centrepiece of re-powering project.
The refit will also see the installation of a modernised weapon suite. The upgrade is expected to boost the warship’s combat capabilities and overall operational effectiveness.
Specialised engineering and ship repair work will be needed for the project which will show how domestic shipyards play a role in maintaining and modernising India’s naval fleet.
Cochin Shipyard to Lead the Refit Project
Cochin Shipyard Limited has been selected to do the normal refit and re-powering work. It is one of India’s major shipbuilding and ship repair organisations and projects have been carried out for commercial as well as defence requirements.
The contract is a big assignment for the shipyard since it replaces a major propulsion system on an existing naval vessel.
More than 50 micro, small and medium enterprises (MSMEs) are also expected to be involved in the project. These businesses are likely to contribute to different parts of ship repair and modernisation process.
The Ministry of Defence has signed a Rs 498.58 Cr contract with Cochin Shipyard Limited for the Normal Refit & Re-powering of INS Betwa. The contract was inked in New Delhi on November 11, 2026, in the presence of Defence Secretary Shri Rajesh Kumar Singh. This project will provide a major impetus to the Government's vision of 'Aatmanirbhar Bharat' and 'Make-in-India', while reinforcing the country's indigenous naval ship repair and maintenance capabilities.

Project Expected to Support Indian Shipbuilding Industry
The INS Betwa refit will create employment in India’s shipbuilding and ancillary industries. Involvement of domestic suppliers and MSMEs could further strengthen the country’s naval maintenance ecosystem.
The project also supports government’s Aatmanirbhar Bharat and Make in India initiatives by developing indigenous capabilities for complex naval repairs and equipment modernisation.
Domestic expertise in propulsion upgrades and ship maintenance is necessary to reduce dependence on overseas support for naval work of a specialized nature.
Why the INS Betwa Upgrade Matters
Warships need maintenance and modernisation to stay operational and effective. A major refit can address old equipment and upgrade important systems while extending a vessel’s usefulness to the Navy.
For INS Betwa, the planned conversion from steam-based propulsion to diesel engine based propulsion (along with modernised weapon suite) is a major technical upgrade.
The ₹498.58-crore contract is therefore significant not just for the Indian Navy but also for Cochin Shipyard and the wider Indian defence manufacturing sector.
The project demonstrates India’s continuing efforts to build up domestic capabilities in naval shipbuilding, repair and modernisation.
