From late 1944, 160 of the special transport variant "Stirling Mk V" were built, which had the tail turret removed and a new nose opening added; most of these were completed after the war. By 1946, the Stirlings of Transport Command were being phased out and replaced by the Avro York, which was a transport derivative of the Lancaster that had previously replaced the Stirling in the bomber role. While many aircraft were scrapped, 12 Stirlings were modified to conform with S.37 standards and sold to Belgian charter operator Trans-Air in May 1947.
