Svenska Aero

For Svenska Aeroplan AB, see Saab.

Svenska Aero was a Swedish aircraft manufacturer on Hästholmen in Lidingö. The company was founded September 10 1921 to license build Caspar-Werke and Heinkel aircraft. The company was bought by ASJA in 1932.

After World War I, the German aircraft industry had several problems. German airlines was forbidden to operate multi engined aircraft and during a period all manufacturing of aircraft in Germany was banned. By 1921, some of the restrictions was lifted, civilian aircraft could be made after approval of an international control commission if they fulfilled certain requirements. In order to bypass these rules and to be able to make whatever aircraft they wanted several aircraft manufacturers moved abroad. In 1921, Carl Clemens Bücker handled the purchase of a reconnaissance aircraft from Caspar-Werke in Travemünde. Because they expected problems due to the rules in the peace treaty regarding the export of German fighter aircraft Bücker explored the possibility to smuggle the parts out of Germany and assemble the aircraft in Sweden.

To make the purchase easier, Ernst Heinkel and Bücker started Svenska Aero in Lidingö 1921. The contract on the aircraft was transferred from Caspar to Svenska Aero. Heinkel and some German assembly workers temorarily moved to Lidingö to assemble the aircraft.

Bücker, who at the time was hired as test pilot by the navy airforce at TDS (Torpeddepartementet på flottans varv i Stockholm, Swedish for "the torpedo department at the navy's whafr in Stockholm"), quit to become CEO and the only board member of the new company. The first aircraft was assembled from components from Caspar-Werke in Travemünde. Some assembly was carried out at Svenska Aero's facilities, but they were finished by TDS some the facilities of Svenska was unsuitable for production. In reality only rudders and pontoons was made in Sweden, the rest of the components was secretly manufactured by Caspar in several locations in Germany to avoid detection of the allies. Duirng 1922 to 1923, the company moved into a former shipyard in Skärsätra on Lidingö since the company had received additional orders from the navy airforce. The parts for those aircraft was made in Sweden by Svenska Aero, but assembled by TDS. In 1928, the navy ordered four J 4 (Heinkel HD 19) as a fighter with pontoons. That delivery came to be the last license built aircraft by Svenska Aero.

In the mid 1920s, Svenska Aero created their own design department to be able to make their own aircraft models. Sven Blomberg, earlier employed by Heinkel Flugzeugwerke, was hired as head of design. In 1930, he was joined by Anders Johan Andersson from Messerschmitt. Despite that, Svenska Aero designed and made six different models on their own the manufacturing was not the success Bücker counted on. The airforce was only interested in buying prototypes and then building them themselves. in their workshops TDS and CFM. This led to financial problems for the company and, in 1932, Bücker decided to sell the company with staff to ASJA for 250,000 SEK. After the company had been sold, Bücker returned to Germany and started Bücker Flugzeugbau. Also, A. J. Andersson joined the new company ad head of design. Together, they created several internationally well known aircraft like Bücker Bü 181 Bestmann and Bücker Bü 133 Jungmeister. At the outbreak of World War II, Autumn 1939, Andersson returned to Sweden where he led the design of the twin engine Saab 18.

Including licence built and own designs Svenska Aero made a total of 58 aircraft. Seven was exported to Latvia and one to Norway. The importance for the Swedish armed forces was greater than the number of manufactured aeroplanes may give the impression of. Between 1926 and 1932, the airforce bought 15 different types of aircraft, of them eight came from Svenska Aero.
