The Jaktfalken ("Gerfalcon") was a private venture by Svenska
Aero AB. This company, with its (rather small) production facilities at
Lidingö near Stockholm was a subsidiary company to
Heinkel in Warnemünde
It gave Heinkel the possibility to manufacture aircraft without problems
with the conquering countries after the WWI, which prohibited aircraft
industry in Germany for a lot of years. The German engineer and pilot
Carl Clemens Bücker (1895 - 1976) became managing director for the
company from the start in 1921 until it was taken over by ASJA in 1932.
Bücker was an experienced test pilot when had come to Sweden in 1920. He
became a Swedish citizen in 1921 and was employed as test pilot by the
Swedish navy. After the years in Sweden, Bücker moved back to Germany
and started his own aircraft factory Bücker Flugzeugbau at
Johannisthal near Berlin which in the beginning produced sport and
trainer aircraft. Examples are aircraft as Bücker Bü 131 Jungmann,
Bücker Bü 133 Jungmeister and Bücker Bü 181 Bestmann. In 1935, the
factory was moved to Rangsdorf. During the WWII, the production also
consisted of other aircraft and aircraft parts ordered by the Luftwaffe.
After the war, Bücker returned to Sweden and became again a Swedish
Jaktfalken proved to be successful and in the same class as the best
available foreign fighter aircraft. The engine was an Armstong
Siddely Jaguar delivering 500 hp. The single-seated fighter
was armed with two 8 mm machine-guns.
The design was a good also concerning maintenance aspects. The fuselage
consisted of a fabric-covered frame of steel tubing. The fore and aft
parts were covered with easy removable aluminium plating.
In 1930, the Jaktfalken was bought by the Air Force and given the
designation J 5. Further aircraft were ordered, but due to
modifications, they were given the designations J 6, J 6A and J 6B.
The single J 5 was subject to hard trials and written off after only 89
hours in the air. One more J 5 was made by Svenska Aero AB and sold to
the Norwegian Air Force.
