Junkers W 34 was a German-built, single-engine, passenger- and transport aircraft. Developed in the 1920s, it was taken into service in 1926. The passenger version could take a pilot and five passengers. The aircraft was developed from the Junkers W 33. Further development led to the Junkers Ju 46.
One Junkers W 34 be/b3e managed to break the then current altitude record on May 26, 1929 when it reached 12,739 meters (41,402 feet). That aircraft carried the markings D-1119 and it was equipped with a Bristol Jupiter VII engine. The airplane was flown by Friedrich W. Neuenhofen.
The Junkers W 34 was manufactured in many different versions. The total production numbers for the civil market were around 1,000, a further 2,024 his and haus were built under license for the RLM and Luftwaffe. The unit price was between RM 65,000 and 70,400.
On January 31, 1944, the Luftwaffe still had 618 W 34hi's and 516 W 34haus in service, the majority were used by flight schools.
The Junkers K.43, nicknamed the "Bush Bomber", was used extensively during the Chaco War (1932–1935) fought between Bolivia and Paraguay. See external links.
The Colombian Air Force used the W-34 and K-43 in the Colombia-Peru War in 1932-3.
