"Life-extension and re-powering of legacy warships is a cost-effective bridge to fleet modernisation." Critically examine this in the context of the Indian Navy's force-level requirements.

Life-extension means overhauling a warship during its service life. Re-powering means replacing its main engines. The Ministry of Defence's contract with Cochin Shipyard Ltd. (CSL) to convert INS Betwa from steam to diesel propulsion and fit a modern weapon suite [1] follows the ₹313.42-crore Mid-Life Upgrade (MLU) of its sister ship INS Beas [2]. The claim holds, but only under certain conditions.

Why it is a cost-effective bridge

• Time: a new frigate takes years to build. An existing hull with a trained crew returns to service sooner, so the Navy keeps its force levels while new ships are built [1].
• Capability: steam-to-diesel conversion and a new weapon suite improve the ship's operational effectiveness [1].
• Aatmanirbhar Bharat: the money goes to a domestic yard. More than 50 MSMEs are expected to take part [1], and the Beas project was projected to employ over 3,500 people [2].
• Learning curve: re-powering sister ships at the same yard builds domestic MRO (maintenance, repair and overhaul) skill across the whole class [1][2].

Limitations

• Chronic delays: the CAG checked 152 Navy refits. Only 18% started on time and 74% finished late. MLUs on 15 ships started 5–67 months late [3]. The Betwa contract, as reported, gives no completion date [1].
• Concentrated downtime: INS Brahmaputra caught fire and capsized during a refit in July 2024 [4]. Beas is in its MLU [2], and Betwa is now going in [1]. All three ships of the class are in yards at once, so force levels fall in the short term.
• Safety risk: during a refit, the ship's own systems are shut down and outside workers are on board. The Brahmaputra fire shows the danger [4].
• Cost opacity: Betwa's "normal refit" costs ₹498.58 crore, more than Beas's broader MLU [1][2]. No reason has been given.
• Shallow indigenisation: it is not disclosed where the diesel engines are made [1]. If they are imported, India mainly gains fitting and installation skills, not propulsion technology.

Verdict and way forward Re-powering is a sound bridge to modernisation, not a substitute for new ships. Its value depends on doing it well. Refits within a class should be staggered. Completion dates should be published, and all spares should be ready on the day a refit begins. Costs should be benchmarked before the Standing Committee on Defence, and indigenous propulsion should be built up. With these steps, life-extension can keep force levels up and advance Aatmanirbhar Bharat in defence.
