ČKD-Praga (Českomoravská-Kolben-Daněk Praga) was a Czechoslovak aircraft manufacturer. The company was founded in 1915 as an engine manufacturing company, under the designation Praga. The company started designing aircraft in 1930–31 when the designers Pavel Beneš and Miroslav Hajn came to ČKD-Praga from Avia. Their first aircraft was the Praga E-39 from 1931. It was a military trainer, with a production run of 139 aircraft. ČKD-Praga developed several aircraft over the following years, but none exceeded prototype stage.2

Products and brands

In the 1930s the company referred to designs by the initials of their designers' surnames, for example the BH-39 trainer, designed by Pavel Benes and Miroslav Hajn. The Czech government identified aircraft by manufacturer, each having a letter assigned to them. Praga's was E, so the BH-39 became the E-39.
