 Swanton Morley was a new station planned under the RAF expansion scheme but not completed to the same standard before the start of the Second World War.It was part of No.2 Group RAF in RAF Bomber Command until December 1944 when it was given over to 100 Group - the RAF unit responsible for countering German defences against the British strategic bombing - as they needed another airfield close to their HQ at Bylaugh Hall.
