The Swiss Air Force uses Sion as one of their four jetfighter air bases, the others being Payerne, Meiringen and Emmen. It is known as Flugplatzkommando 14 Sion. In addition to the prop-types Pilatus PC-6, Pilatus PC-7, Pilatus PC-9 and Pilatus PC-21 as well as helicopters it uses Sion intensively with the fighter jets F/A- 18 and F-5 Tiger. It is the home base of the militia pilot sqd., Sqd.19 Swans with F-5E and Sqd.16 Dragons with F-5F. Sion Airport is, at both end of the runway, equipped with retractable Arresting gear devices (used by the F/A-18 and in case of a problem by the F-5). Because of the redimension of the Swiss Air Force it is planned that the Air Force will leave Sion after 2016 and Sion will be used by civil aviation only.
