From 1954 Canberra bombers equipped 69 (briefly), 102, 103, 104, 149 Squadrons, and later 59 Squadron at RAF Gütersloh. This force was under Bomber Command control from Britain and had been moved to Germany because of overcrowding of suitable airfields in the UK. With the establishment of the British nuclear bomber forces in the context of NATO's strategy of massive retaliation the Canberra bomber squadrons were again withdrawn from Germany.
