The squadron was re-formed on 12 November 1942 at RAF Jui, in Sierra Leone, with Consolidated Catalina IB an American flying boat and amphibious aircraft.[1] It flew sorties into the mid-Atlantic off West Africa on anti-submarine patrols,[2] sinking a U-boat in January 1943.

In July 1943 the squadron moved to Lagos, in Nigeria, to be based at RAF Apapa and at the end of that year it re-equipped with the four-engined Short Sunderland flying boat patrol bomber. The squadron operated detachments at RAF Jui, Abidjan and Libreville. No. 270 Squadron was disbanded, after the war in the Atlantic had ended, on 30 June 1945 at Apapa, Nigeria.[2]
