Second Allied Tactical Air Force (2 ATAF) was a NATO military formation under Allied Air Forces Central Europe tasked with providing air support to NATO's Northern Army Group (NORTHAG). 2ATAF commanded all flying units based within its sector and all reinforcements flying into its sector, as well as ground based radar systems and stations, air defense units and the airfields in its sector.
Second Allied Tactical Air Force was formed in 1958 with its area of responsibility covering the Netherlands, Belgium, and Germany north of the city of Kassel and south of the Elbe river. Commander of Second Allied Tactical Air Force was the commanding Air Chief Marshal of the British RAF Second Tactical Air Force, which was renamed RAF Germany on 1 January 1959.
The peacetime headquarters of 2 ATAF were at RAF Rheindahlen, the command center in the case of war for 2ATAF and NORTHAG was in the Netherlands at Joint Operations Center Maastricht (JOC Maastricht). In 1983 NATO began with the construction of Static War Headquarters Castlegate in Linnich, Germany, as a replacement for JOC Maastricht. Alternate War HQ was located at Kanne (Belgium) north of Fort Eben-Emael. Second Allied Tactical Air Force commanded the British Royal Air Force Germany, the Belgian Air Force, the Royal Netherlands Air Force, two divisions of the German Air Force (Luftwaffe) and one US Air Force Tactical Fighter Group, as well as extensive air defense and radar installations provided by Germany, Belgium and the Netherlands.
