Norway had its own aircraft production, from 1913 to the late 1950s, with over 200 aircraft produced in the period. In the beginning, production was based on copies and licenses of aircraft from abroad, but eventually aircraft with a Norwegian design were also developed and produced. One of the first was Einar Lilloe Gran. He built an airplane as early as 1909. He was an engineer and had learned airplane construction in Paris. He built the fuselage and wings in steel tubes, the wings were covered with impregnated cotton cloth. The aircraft was a high-winged monoplane, had a front and rear wing, and some small swiveling wing stubs for maneuvering. it had a very light construction. But during the first test flight the plane crashed, after barely getting airborne. It was not repaired, presumably the whole structure was too flimsy.
In 1913, a French Deperdussin was imported and assembled in a tramway stable at Sagene in Oslo. The aircraft was a monoplane with a body in shell construction made of plywood. The engine was a rotary Gnome with 100 hp. It flew well, but crashed at Gjøvik. The plane belonged to Juul Hansen.
Flyvebåtfabrikken started building more modern reconnaissance aircraft in 1918, with four-blade pull propellers, biplanes, and canvas-covered body in frame construction, inspired by the Sopwith Baby and Short 184.
8 aircraft were built, but there were many accidents, and the aircraft saw little use. The engine was an unreliable 160 hp Sunbeam. Two aircraft received 240 hp Siddeley Puma. The engine was covered with metal. The planes were scrapped in 1926.
The development of aircraft equipment in Europe during the First World War also affected the Norwegian aircraft designs at this time. The Navy’s Aircraft Factory in Horten worked on a new type of scout plane that was to replace the old Farman-inspired machines. It was to be a two-seater biplane with a four-bladed propeller and was probably also somewhat influenced by the experiences with the Sopwith Baby, which had now been put into use. The first plane crashed already during the test flights in Horten in November 1918 after barely two hours in the air, but it was still decided to build 8 planes in the period 1919-1922. The first six were fitted with a 160 Hp Sunbeam engine built in England, but these proved very unreliable, and the last two aircraft were therefore fitted with the 240 Hp Siddeley Puma without it helping performance much. The aircraft type was little used and five crashed in the run of 1921/22. the rest were stored in Kristiansand until they were scrapped in August 1926. Only one of the planes had then spent more than 50 hours in the air
