The Dewoitine D 27 was designed in Switzerland and built there by the EKW state aircraft factory at Thun. It first flew in 1929, with an SLM Saurer built Hispano Suiza 12 Mc engine of 600 hp, and a total of 85 were built at Thun between 1929 33. Sixty six of these were delivered from 1930 to the Swiss Fliegertruppe, which also received 11 examples of the D 26, a version fitted with a 250 hp Wright Cyclone radial engine.
Most of the D 26s were used as advanced trainers, but after World War II a number survived doing duty as tugs for sailplanes.
