The interest to establish an airfield and military base at Haslemoen was first articulated by the Norwegian Army Air Service in the late 1930s.

They therefore proposed that the relatively flat, forested areas at Haslemoen would be a suitable site for a main air station.

They were concerned about an attack on Norway and wanted to establish a reserve air base for Gardermoen, located far from the coast.

Both a runway, measuring 1,800 by 60 meters (5,910 by 200 ft), and a taxiway were built, along with auxiliary buildings, barracks, hangars, storehouses and workshops.

[4] From 21 November it served as a base for a squadron of the remaining Focke-Wulf Fw 200 Condors in Norway, reaching 28 aircraft by 28 December.

[3] RNoAF allocated Haslemoen to a light bomber squadron, which was to be operated on a repetition- and mobilization basis.

[3] The Air Force took delivery of the Cessna O-1 Bird Dog in 1960, and those allocated to Southern Norway were stationed at Haslemoen.

[9] A government commission considered Haslemoen in 1988 as a potential main air station for Eastern Norway.

The main concern was that its proximity to Sweden meant that operations would cause problems for the self-imposed no-fly zone for allied aircraft.

[12] The municipality changed the focus away from motor sports and instead initiated a program to cultivate 6 square kilometers (2.3 sq mi) of the former base, including the airfield area.

[13] In its military days, the air base boasted a concrete runway measuring 1,800 by 60 meters (5,910 by 200 ft).
