RFN is the largest overland test range in Western Europe, consisting of 1,650 km² of uninhabited forest and marshland, which can be extended by 1,500 km² if required. The installation includes a military base with a 2,300 m runway. Because of its usage as a Swedish and European missile test site, this remote area is often listed in international weather forecasts and maps.
The site has been a test area for most Swedish flight developments, including Draken, Viggen and Gripen. New tests with EADS Phoenix and Eurofighter, as well as European military trainings, are planned for the future.
