The system originated from an air force inquiry in 1954 and was formally implemented in the 1958 defence plan.
The original plan called for 70 wartime air bases to be built, with 46 of them to be equipped for continuous usage.
The base system was therefore never fully active during the time it existed, like the rest of the Swedish Armed Forces during the Cold War.
Uppställningsområdet (uom), staging area, was where aircraft undergoing long-term maintenance, such as repairs, or not being in immediate use were kept.
A uom had field hangars for maintenance work and a site for engine swapping and testing.
Just like at bakom the aircraft spaces at uom could be concealed with camouflage nets and was connected with the rest of the base via a taxiway that often was public road.
To complement the ordinary Bas 60 bases, reservvägbaser (road runways) were built to act as a backup alternative.
Selected sections of public roads that were suitable for the purpose were widened to give enough space for aircraft to take-off and land.
Usage of the road runways were limited by adverse light and weather conditions, which is why they were primarily considered a backup alternative.
The air traffic operations on a base were led and organized from a kommandocentral (command centre), abbreviated as KC, located in an underground bunker a few kilometers away from the airfield.
In case kommandocentralen was unavailable or stopped functioning the TLF could take over control of air traffic operations.
The overarching and long term operations on base were led and organized from a stabsplats (command post).
A fully mobilized battalion consisted of 1200-1500 men, but in peace time a base was normally operated by 2-3 technical officers and 10-15 conscripted flight mechanics.
