'''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 '''hi'''s and '''hau'''s were built under license for the RLM and ''RM 65,000 and 70,400.

On January 31 1944, the ''Luftwaffe'' still had 618 W 34''hi'''s and 516 W 34'''hau'''s 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&ndash;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.

'''Junkers W 34''' var ett tyskt enmotorigt, lågvingat passagerar- och transportplan som utvecklades på 1920-talet och som togs i bruk 1926. Flygplanet hade utvecklats ur den tidigare modellen Junkers W 33. Passagerarversionen kunde ta piloten och fem passagerare, senare tillkom en plats för en andrepilot. En ytterligare utveckling ledde till flygplanet Junkers Ju 46.

W 34 exporterades till ett stort antal länder, däribland Finland, Kanada, Kina, Norge, Nya Guinea, Spanien, Sverige och Sydafrika.

En W 34 be/b3e lyckades slå höjdrekordet den 26 maj 1929 genom att flyga till 12 739 m höjd. Flygplanet bar beteckningen D-1119 och var utrustat med en Bristol Jupiter VII-motor. Flygplanet framfördes av piloten Friedrich W. Neuenhofen.

Junkers W 34 kom att tillverkas i ett mycket stort antal versioner. Man tillverkade omkring 1 000 flygplan enbart för den civila marknaden. Till detta antal kom ytterligare 2 024 exemplar av modellerna "hi" och "hau", som byggdes av ett stort antal företag på licens för RLMs och Luftwaffes räkning. Enhetspriset rörde sig mellan 65 000 och 70 400 Reichsmark (ca 8,8-1,04 miljoner svenska kronor med 2006 års kurs).

Den 31 januari 1944 hade Luftwaffe ännu 618 W 34 hi och 516 W 34 hau i tjänst, de flesta användes av flygskolor.
