The former RAF Second Tactical Air Force (2TAF) was one of three tactical air forces within the Royal Air Force (RAF) during and after the Second World War. It was made up of squadrons and personnel from the RAF, the air forces of the British Commonwealth and exiles from German-occupied Europe. It was formed on 1 June 1943 as HQ Tactical Air Force from Army Co-operation Command in connection with preparations then in train to invade Europe a year later. It took units from both Fighter Command and Bomber Command in order to form a force capable of supporting the Army in the field. Bomber Command lent No. 2 Group with light bombers, and Fighter Command was split up into the Air Defence of Great Britain, retaining fighter units for home defence, and No. 83 Group and No. 84 Group for the Second Tactical Air Force.
