The squadron transferred to the escort carrier on 31 December 1943, and returned ashore at RNAS Hatston and RNAS Machrihanish (HMS Landrail) in January 1944. Most of 1944, however, was spent onboard "Nairana", on Atlantic convoy duties and on the Gibraltar Run. The squadron also served in 1944 with a successful submarine Hunter-Killer Group in the North Atlantic under the overall command of Captain Frederick Walker. Three Ju 290s were shot down in May and June. The squadron became involved in the Murmansk Convoys to and from RNAS Hatston in August. Squadron pilots faced the most dangerous flying conditions of the war to attack two U-Boats and shoot down four enemy aircraft in the Arctic. The aging Sea Hurricanes were replaced by Grumman Wildcat Mk.VIs in September.
