The Junkers Ju 89 was a prototype heavy bomber developed by Germany in the mid 1930s.

History[edit | edit source]

Spurred by far-seeing Generalleutnant Walther Wever, the RLM issued a specification in mid-1935 for a Langstrecken-Grossbomber (long-range heavy bomber), which was popularly called the Ural-bomber, though it had to reach the tip of Scotland as well. The Do 19 and Ju 89 were the main responses. and the Junkers was by far the more capable. The Ju 89 V1 flew in December 1936, followed by V2 in early 1937. Under the leadership of Dipl-lng Ernst Zindel this very big and impressive machine had taken shape quickly, with smooth dural skin, double-wing flaps, hydraulic landing gear and crew of nine.

Intended armament comprised a 20mm cannon in dorsal and ventral turrets and front and rear MG 15 machine guns. lnternal bomb load was 16 bombs of 220lb (100kg) or similar combinations. After Wever's death the programme trickled on until termination on 29 April 1937. The two Ju 89s continued intensive flying; V1 gained load/height records in 1938, one being 11,023lb (5000kg) to the excellent height of 30,551ft — well over 10,000ft above the ceiling of a Stirling with a similar load.[1] The Ju89 design formed the basis of the Ju 90 airliner, which led to the Junkers Ju 290.[2]
