Interlaken Air Base

Interlaken Air Base is a former military installation located in Interlaken, Switzerland. A civilian airfield occupied the site from 1919 until its closure in 1930. The military facility was constructed in 1940 during the Second World War as a Swiss Reduit airfield and commenced operations in 1941. The Swiss Air Force operated various aircraft types at the facility, including the Northrop F-5. In 1947, a specialist department for de Havilland Vampire aircraft was established at the base. During the Cold War, the installation functioned as the operational base for Squadron 7, which utilized Hunter aircraft, and served as a maintenance facility until 1990.

Military use of the airfield ceased in 2003 and the site was subsequently sold. It is currently closed to scheduled commercial flights. Swiss Air Rescue maintains a presence at the airfield, having originally formed its Wilderswil base there in 1971. After moving to an external heliport in 1982, the rescue service returned to the Interlaken airfield in 2008 while retaining the Wilderswil name.

The airfield infrastructure has been repurposed for non-military applications. In 2023, the Matten bei Interlaken railway station opened on the site. Other portions of the facility are used for Jungfrau Park and the annual Greenfield music festival. The site has also hosted motor racing events and air sports. Between 1964 and 1967, the airfield supported seasonal charter flights from London.
