The Armstrong Whitworth A.W.27 Ensign was a British four-engine monoplane airliner and the largest airliner built in Britain during the Interwar period.[1]

The British airline Imperial Airways requested tenders for a large monoplane airliner with four Armstrong Siddeley Tiger engines in 1934. Armstrong Whitworth designed the Ensign to seat up to 40 passengers for the airline's European and Asian routes while also carrying airmail. It connected Britain with seaplane flights that continued on to Australia and South Africa. Early operations were hindered by mechanical problems and modifications only ever marginally improved performance and reliability.

During the Second World War, the Ensigns were operated by the British Overseas Airways Corporation (BOAC), which had been formed out of the merger of Imperial Airways and British Airways. The type would be flown between Britain and various locations in the Middle East, Africa and India, often in support of military operations. During 1940, two Ensigns were destroyed by enemy action, while one would be captured in 1942 and subsequently operated by the French. The Ensigns were retired following a final passenger flight in June 1946 and the remaining aircraft were scrapped the following year.
