No. 428 Squadron RCAF
No. 428 Squadron RCAF was the ninth long-range heavy bomber Article XV squadron formed overseas during the Second World War at RAF Dalton in Yorkshire, England on November 7, 1942.

No. 511 Squadron RAF
Formed on 14 October 1942, No. 511 Squadron was formed from No. 1425 Flight at RAF Lyneham. The squadron continued the work of the Flight operating regular transport schedules to Gibraltar using the Consolidated Liberators. To extend the route from Gibraltar to Malta the squadron also operated the Armstrong Whitworth Albemarle. As the Second World War progressed, no. 511 Squadron expanded its long-range transport role and it was the first squadron to operate the Avro York transport (A transport based on the Avro Lancaster). At first the Liberators and Yorks were operated as separate Flights, but the Liberator Flight became 246 Squadron in 1944. The squadron continued to fly trooping flights, particularly between the United Kingdom and India until the squadron was disbanded on 7 October 1946.
