The Junkers K 30 is the military version of the Junkers G 24 airliner .


Spain , Chile and the Soviet Union showed interest in such a guy. The K 30 was assembled in Limhamn , Sweden by AB Flygindustri from parts supplied by Dessau . Only the prototype was completely manufactured in Dessau and also flown in because the construction of military aircraft was still forbidden in Germany in 1925 .

Of the 30 copies made in Limhamn, 23 were sold to the USSR, where they were partly armed in the Fili assembly plant . This model received the type version R 42 and was flown by the Soviet armed forces as JuG-1 from 1926 , retired in 1931 and continued to be used as a civilian passenger and cargo aircraft. In the summer of 1928, the JuG-1 "Krasni Medwed" (Red Bear) participated as an aircraft on board of the icebreaker Krasin in the rescue of the crew of the airship Italia , which had crashed in the polar region ; On July 10th, part of the stranded airship was sighted by the aircraft occupants for the first time.

Six copies went to Chile, one received Spain.

The K 30 was equipped with each 228 kW Junkers L 5 and, as the K 30w, could also be equipped with snow runners or floats instead of the normal chassis . The crew was about four men. There were a total of three machine gun positions, two in twin design in front and behind on the back of the fuselage, the third was on the underside of the fuselage and was designed to be retractable. Each machine gun had 500 rounds. 500 kg of bombs or, alternatively, a 45 cm torpedo could be carried.
