The last of the AWACS flights left Afghanistan on 25 September 2014, returning to Geilenkirchen in Germany after flying 1,240 missions.
NATO AWACS (Airborne Warning and Control System) is the only platform which is owned by an alliance (and not a country), a proof of concept for NATO itself. Sixteen different nations working together provide air traffic control for airspace above Afghanistan, making sure the numerous military and civilian flights that take place do not interfere with each other.
