The airline's initial fleet consisted of two five-seat Curtiss Kingbirds, two four-seat Junkers F 13s and one ten-seat Tupolev ANT-9. In 1935, the airline was turned over to the Ministry of Public Works and was subsequently renamed General Directorate of State Airlines. Three years later, in 1938, it became part of the Ministry of Transportation.
