Svenska Aero

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 1921, Carl Bücker [de] handled the purchase of a reconnaissance aircraft from Caspar-Werke in Travemünde.

To make the purchase easier, Ernst Heinkel and Bücker started Svenska Aero in Lidingö in 1921.

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 wharf in Stockholm"), quit to become CEO and the only board member of the new company.

In reality only rudders and pontoons were made in Sweden, the rest of the components were secretly manufactured by Caspar in several locations in Germany, to avoid detection by the allies.

The manufacturing was not the success Bücker counted on, as the airforce was only interested in buying prototypes and then building them themselves in their workshops TDS and CFM.

At the outbreak of World War II, autumn 1939, Andersson returned to Sweden where he led the design of the twin engine Saab 18.
