INS Beas (F137) was a Leopard-class frigate operated by the Indian Navy, representing a notable example of mid-20th-century naval design and capability. Constructed by Vickers-Armstrongs Ltd in Newcastle upon Tyne, she was launched in 1958 and commissioned into service in 1960. The vessel’s design was rooted in the British Leopard-class anti-aircraft frigates, which were among the prominent warship classes of the era. The ship’s physical characteristics, while not detailed in the provided content, would align with typical Leopard-class specifications, which generally featured a displacement of around 1,350 tons, a length of approximately 339 feet, and armament suited for anti-aircraft and surface warfare roles. Her pennant number was initially F137, which was later changed to F37 in the 1980s, reflecting her long service life and updates in naval designation practices. Throughout her operational career, INS Beas played a significant role in several key military engagements. She participated in the Battle at Mormugão harbor in 1961, a notable confrontation during the Indo-Pakistani War of 1961. Later, during the Indo-Pakistani War of 1971, she contributed to naval operations, demonstrating her versatility and combat readiness. Among her notable actions was her involvement in amphibious landings at Cox's Bazar, where alongside her sister ship INS Brahmaputra, she facilitated landing divers and provided gunfire support, underscoring her role in joint amphibious operations. INS Beas was decommissioned in 1988 after nearly three decades of service, marking the end of her operational life. She was subsequently scrapped in 1992. Her service history highlights her importance in India’s naval history, particularly in regional conflicts and amphibious operations, reflecting her significance as a versatile and reliable warship within the Indian Navy’s fleet during the Cold War era.
