Production and service

One Junkers W 34 be/b3e managed to break the then current altitude record on May 26, 1929 when it reached 12,739 meters (41,795 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.

Swedish Junkers W 34 SE-BYA was flown by the Swedish Air Force 1933-1953 as the Trp 2A and Tp 2A ambulance aircraft. Stockholm Arlanda March 1968.

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.^[2]
