Avro Lancaster PA474 is a four-engined, Second World War era, Avro Lancaster heavy bomber operated by the Royal Air Force Battle of Britain Memorial Flight as a tribute to all members of Bomber Command during the Second World War.

[1] PA474 was built as a B Mk 1 (B1) by Vickers-Armstrongs Ltd at its Broughton factory near Chester in 1945 and was to be part of the British Tiger Force for strategic bombing in the Far East.

With gun turrets removed it was assigned to Photographic Reconnaissance duties with 82 Squadron in East and South Africa.

[2] Flight Refuelling used an Avro Lincoln instead and PA474 was then transferred to the College of Aeronautics, Cranfield, Bedfordshire to be used for trials on the Handley Page laminar flow wing.

[2] PA474 was stored first at Wroughton and then at Henlow then, after a request in 1965 from 44 Squadron, the Lancaster moved to RAF Waddington for restoration back to wartime standard including refitting the front and rear turrets.
