The Junkers K 47 was a two-seater fighter aircraft developed in Sweden by the Swedish subsidiary of the German firm Junkers during the late 1920s, a civil development of which was designated the A 48.
Designed to meet a requirement of the Turkish government for a new fighter, the K 47 was a strut-braced, low-wing monoplane of conventional design. Two open cockpits accommodated the pilot and tail-gunner, and the empennage was designed with twin vertical surfaces to maximise the rearward field of fire. The main units of the fixed, tailskid undercarriage shared part of the truss structure that braced the wings. The design was originally undertaken by Karl Plauth, but completed after his death by Hermann Pohlmann. The aircraft had to be built at first in Sweden, because it was patently a military-type aircraft and therefore banned in Germany according to the terms of the Versailles Treaty.
By the time the K 47 prototype was complete, Turkey had already lost interest in the type, but with the Soviet Union indicating interest, work continued. Eventually, however, the Soviet government only purchased two or three examples.
The only operational use of the type was China (Nanking government), which bought ten aircraft in 1931, and was presented one more in 1934 (the last one was named the T'ien C'hu No.1, after the factory, which had funded it). [1] With the flare-up of the Shanghai Incident of 1932, the Chinese Air Force dispatched various fighter-attack planes to the Shanghai Hongqiao Aerodrome and the Hangzhou Qiaosi Airbase, while the Imperial Japanese Navy dispatched planes from aircraft carriers Hōshō and Kaga ; a surprise attack by a 15-aircraft formation composed of Nakajima Type 3 fighters and Mitsubishi Type 13 attack-bombers saw a Chinese Junkers K 47 with pilot Shi Bangfan and his rear-seat gunner Shen Yanshi just managing to takeoff from Qiaosi as the Japanese raid commenced, and although gunner Shen's gun jammed, pilot Shi would continue to dogfight the Japanese, eventually pilot Shi was shot and his engine damaged, and had to force-land his Junkers.

Demonstrations were also carried out in Romania, Portugal, and Latvia without any resulting orders, although one aircraft may have been purchased by Japan. Three aircraft were used by the Reichswehr clandestine training facility at Lipetsk and a small number of the unarmed civil version were purchased by the DVS.
K 47s were also used in trials to investigate dive bombing, experiments that would be formative of Pohlmann's thinking in designing the Ju 87. Indeed, the second Ju 87 prototype was fitted with a K 47 tail.
