its attack. In January 1944, supporting convoy SL 147/MKS 38, Starling shared in the destruction of . In February she took part in the famous "Six in one trip" episode, where 2 SG destroyed six U-boats over a two-week period. Starling shared in the destruction of four of these; on 31 January, and on 9 February, and on 19 February. In March 1944, Starling and 2 SG, accompanied by escort carrier Vindex, sought and destroyed , a U-boat on weather-reporting duty in the North Atlantic. Later that month, while supporting Murmansk convoy JW 58, Starling met and destroyed in transit to the North Atlantic. She had no other success, though three U-boats were destroyed in attacks on JW 58. In May the group responded to an attack on by . Though starting from 300 miles away Walker, in an inspired piece of work, divined where to search and after a three-day search gained contact. An 18-hour hunt brought U-473 to the surface, where she was sunk by gunfire. In June Starling was part of "Operation Neptune" in support of the Normandy landings, and was instrumental in preventing any attacks on the invasion fleet. In all fifteen U-boats were destroyed in attempts to attack the invasion fleet, though Starling herself had no success. In July Starling suffered her heaviest blow when Capt.

NW Duck, Starling and 2 SG had another successful patrol in the Bay of Biscay in August, when four U-boats were destroyed; Starling took part in three of these actions, against , , and . In September Starling moved to 22EG, under Cdr. GWE Castens, but the U-boat war had changed character, and Starling saw little further success. The campaign became a hunt for single raiders operating in the shallow coastal waters, where a U-boat could hide among the wrecks on the sea bottom. Hunts for these "lone wolves" was a slow and tedious business, though merchant ship losses were kept to a minimum. In January 1945 Starling, with ships of 22EG, attacked a promising target in the North Channel: They were credited, following examination of German records in the post-war period, with the destruction of . However this assessment was re-evaluated in 1991, and the credit withdrawn; the attack was deemed to have been on a non-sub target. With the
