The Armstrong Whitworth Ensign was a British four-engine airliner built during the 1930s for Imperial Airways. It could seat 40 passengers and was designed for European and Asian routes, connecting Britain with further seaplane flights to Australia and South Africa. In the Second World War, they were used for transport duties to and from the area of Middle East command. After the war, they were withdrawn from service but - with no buyers forthcoming - scrapped.
