INS Beas (F37) is a Brahmaputra-class frigate of the Indian Navy, built entirely in India at the Garden Reach Shipbuilders and Engineers (GRSE) in Kolkata. This vessel is a modified version of the Godavari-class frigate, featuring modern sensor suites and matching weapon systems, reflecting contemporary naval technology. The ship is named after the River Beas, becoming the second Indian Navy vessel to bear this name; the first was a Leopard-class frigate active from 1960 to 1992. Constructed with a focus on versatility and modernization, INS Beas has played a significant role in India's maritime operations. Notably, it participated in a deployment to Europe from May to July 2009, during which it engaged in joint exercises with the Royal Navy and the French Navy. These included Exercise Konkan-09 off the UK coast with the Royal Navy and Exercise Varuna 2009 off the coast of France with the French Navy, demonstrating her operational capabilities and fostering international naval cooperation. As of October 2023, the Indian Ministry of Defence signed a contract with Cochin Shipyard Limited for a mid-life upgrade of INS Beas. This upgrade, initiated in April 2024, marks the first of its Brahmaputra-class ships to undergo comprehensive modernization. The refit involves converting the ship's propulsion system from steam turbines to a CODAD (Combined Diesel and Diesel) configuration, likely fitted with Caterpillar marine diesel engines producing around 6 MW of power. This transition aims to address issues such as steam leaks and high temperatures in the boiler and engine rooms, which previously affected crew comfort and increased maintenance requirements. The upgrade project is expected to take approximately two years, extending the vessel's service life from the current 10 years to over 25 years, thus significantly enhancing her operational longevity and reducing maintenance demands. Overall, INS Beas is a modern, versatile frigate that has contributed to India's maritime security and international naval cooperation, with ongoing upgrades ensuring her relevance and operational effectiveness for decades to come.
