During peace time the air squadrons were stationed at their respective air wing and deployment to the wartime air bases would only occur when the threat level increased. But many of the air wings also doubled as wartime air bases and thus some air wings were also built to Bas 90 standard. The wartime air bases were only manned by a smaller bastropp (base troop) during peace time and the full base battalion would only be manned with a mobilization (except during certain exercises). This was because the majority of the units were made up by conscripts. 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 and the immediate period after.

List of Bas 90 air bases
editInitially the Bas 90 project focused on expanding the air bases in northern Sweden, as the air force wanted to increase the base capacity in the region.
