Back in action 5 November 1943, "Carmick" crossed the Atlantic guarding a convoy to Derry, Northern Ireland in November, escorted to Aruba in December, and in January 1944 protected during the aircraft carrier's shakedown training off Bermuda. In February, she tested equipment for the Bureau of Ships and escorted to Trinidad. This phase of "Carmick"s contribution to the growing might of the Navy ended when the destroyer was assigned to hunter-killer operations with Destroyer Squadron 18 (DesRon 18) from 29 March.
