During the cold war, the Swedish Air Force had a doctrine of dispersed basing in case war broke out. This concept was conceived in the 1950's and was called "Bas 60" and several wartime air bases were built across the country, including road runways as backup bases to the regular ones. The idea was that by having many bases and no more than one squadron of aircraft per base, each base would be a small and uneconomic target for nuclear weapons and ensure endurance and survivability for the air force. "Bas 60" was primarily dimensioned around the nuclear threat, so when long range attack aircraft (such as the Su24) emerged as a threat in the 1970's and 1980's the system needed further development. The result was "Bas 90".

This is an information film about the then new Airbase System 90 (Bas 90) in the Swedish Air Force, from 1986. The film shows and explains the concept of the system, including road runways and mobile ground crew.
