HMS Starling (U66) was a modified Black Swan-class sloop of the Royal Navy, constructed by Fairfield Shipbuilding and Engineering Company in Govan, Scotland. Laid down on 21 October 1941, she was launched on 14 October 1942 and commissioned on 1 April 1943, achieving a build time of just over 17 months. The vessel featured the typical design of the Black Swan class, optimized for anti-submarine warfare, with a displacement and armament suitable for its wartime role, although specific measurements are not provided in the source. Commissioned under Captain Frederic John Walker, HMS Starling became a key component of Western Approaches Command, serving with the 2nd Support Group (2SG). This flotilla comprised six sloops, including Cygnet, Kite, Wild Goose, Woodpecker, and Wren, tasked with hunting U-boats across the Atlantic rather than convoy protection. Starling's service was marked by aggressive and successful anti-submarine operations, making her the most successful Royal Navy vessel of her kind during WWII, credited with the destruction of fourteen U-boats, although some credits were later re-evaluated. Starling's notable wartime achievements include her first success on 1 June 1943, when her group destroyed U-202 after a prolonged 15-hour hunt. She participated in "Operation Musketry," where she rammed and sank U-119, and contributed to the destruction of multiple U-boats during the intense "Six in one trip" episode in early 1944, sharing in the sinking of U-592, U-734, U-238, and U-264. Her operations extended to supporting convoy battles, including the Normandy invasion during "Operation Neptune," where she helped prevent attacks on the invasion fleet. The vessel suffered the loss of Captain Walker in July 1944 due to overwork and exhaustion. Under new command, she continued her patrols, notably in the Bay of Biscay, where she participated in the destruction of U-333, U-736, and U-385. Later, her role shifted as the U-boat threat changed, focusing on hunting lone raiders. Post-war, she was decommissioned in 1945, reactivated in 1946 as a navigation training ship for HMS Dryad, and served in this capacity for a decade. Her final voyage included a visit to Kiel and a farewell event in Liverpool before she was paid off in 1956. Throughout her service, HMS Starling was a symbol of relentless anti-submarine effort and played a significant role in the Atlantic campaign, credited with sinking or damaging numerous U-boats during her operational tenure.
