The Ministry of Defence has contracted Cochin Shipyard Limited (CSL) to carry out a major refit and re-powering of INS Betwa, a Brahmaputra-class guided-missile frigate in the Indian Navy. The agreement, valued at ₹498.58 crore, was signed in New Delhi on November 11 in the presence of Defence Secretary Rajesh Kumar Singh. The work will replace the ship’s existing steam-based propulsion system with a diesel-engine-based system and install a modernised weapon suite.
The propulsion change is the centrepiece of the project. The ministry says the work will also upgrade the frigate’s combat capabilities, with the aim of improving its operational effectiveness. It has not publicly specified the new engines, weapons, refit duration or expected completion date. The contract is described as a “normal refit and re-powering”, rather than a new-build programme.
The project is expected to involve more than 50 micro, small and medium enterprises, supporting employment across shipbuilding and related industries. The ministry says the work will strengthen India’s domestic capacity for ship repair and maintenance, particularly for complex propulsion transformations and the modernisation of naval platforms. It also links the project to the government’s “Aatmanirbhar Bharat” and “Make in India” initiatives.
For CSL, the contract adds a substantial naval refit to its portfolio. The Kochi-based shipyard undertakes shipbuilding and repair work, including projects for the Indian Navy and other customers. The Betwa assignment will require coordination across engineering, equipment supply and ship-repair activities, with the anticipated MSME participation widening the project’s industrial footprint. The ministry has not released a breakdown of the contract value by work package or supplier.
INS Betwa was commissioned into the Navy in July 2004. The frigate is named after the Betwa River and belongs to the Brahmaputra class. Its service history includes a serious dockyard accident in Mumbai in December 2016, when the ship toppled onto its port side during undocking amid a refit. Two sailors died and others were injured. The vessel was salvaged, repaired and returned to operational service after extensive work.
That history makes the current refit notable: Betwa has already undergone a difficult restoration, and now faces another major engineering transformation. Replacing a steam plant with a diesel-based system is a substantial change to a ship’s propulsion architecture. The ministry has not published technical details on how the new configuration will be integrated, nor provided a schedule for testing or return to service.
The contract comes as the Navy seeks to maintain the readiness of its existing fleet while adding newer ships. Refits and upgrades can extend the useful service of older platforms and bring selected systems up to date, though they do not make a vessel equivalent to a newly built warship. For Betwa, the work combines propulsion replacement with a weapons-suite modernisation, but the specific capability improvements have not been disclosed.
The ministry’s announcement positions the project as both a fleet-maintenance effort and an investment in domestic ship-repair capability. The immediate milestones will be the start and progress of work at CSL, followed by trials and Navy’s acceptance. Until the ministry or shipyard provides a completion timeline, the frigate’s return-to-service date remains unannounced.
