Introduction 1926

Developed into Junkers Ju 46

The 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, noted for being a record-breaking aircraft. Further development led to the Junkers Ju 46, which was seaplane for naval use capable being catapulted.

Production and service

One Junkers W 34 be/b3e managed to break the then-current altitude record on 26 May 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 Willi 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

RM
65,000 and 70,400.

On 31 January 1944 the Luftwaffe still had 618 W 34hi's and 516 W 34haus in service: the majority were used by

flight schools; mainly as navigator[2]
and radio operator training (3 or 4 navigator or radio-operator trainees).

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.

Colombia-Peru War in 1932–3.[3]

The Swedish Air Force operated three W 33/34 between 1933 and 1953 in the transport and air ambulance roles, initially with the military designation Trp 2 and Trp 2A, eventually changed to Tp 2 and Tp 2A. One of these is preserved today in civilian colors as SE-BYA.

In 1930

Continuation war the planes were used as transports, evacuating wounded and supplying Long-Range Recon Patrols behind the enemy lines. Additional five W 34s were bought in 1944 for radio navigation training (JU-131 – 135), after the war Finnish Border Guard
operated the remaining planes until 1950.
