From 1912 to 1944 Norway had two separate air arms run by the Navy and Army. Each service also had their own aircraft factory. The Army's was located at Kjeller, Norway's oldest airfield and it is still operated by the RNoAF in 2025. Following WW1, Norway had a need for a scout plane and landed on the Hannover CL.V which was produced under license by Flyvemaskinfabrikken at Kjeller. 203 was the first of 14 FF.7 Hauk (Hawk) to enter service on 19 September 1922 and the last to be retired 22 April 1933. In 1924he type set the Scandinavian altitude record of 8,450 metres.

The Kjeller FF.7 Hauk (Hawk) was a licence built version of the Hannover CL.V biplane ground attack aircraft developed in Germany during WW I. Hærens Flyfabrikk of Kjeller built 14 of these aircraft for the Norwegian army. The aircraft served from 1923 till 1929. This is the only part saved of these aircraft.
