*The Ju90V1, which was original the Ju89V3, was first flown on August 28th 1937 . During the following flight tests, this prototype crashed on February 7th 1938 due to structural failure during overspeed. The second prototype was delivered to Lufthansa in May 1938 for operational test flights. This second prototype also crashed on November 21st 1938 during tropical flight tests at Bathurst due to an engine failure during take off.
In November 1938 Lufthansa ordered three Junkers Ju90, a further Ju90 was ordered by RLM for flight tests. This aircraft was later also taken over by Lufthansa. South African Airways ordered a further two Junkers Ju90 with Twin Wasp engines. These two aircraft were not delivered until the breakout of WWII and both later went to Luftwaffe. Lufthansa finally ordered a total of 12 Junkers Ju90. Just six were delivered until September 1939. These aircraft were transfered to Luftwaffe together with further deliveries from Junkers. They were used during the occupation of Norway as transport aircraft. Some of them later returned to Lufthansa for a few months, but finally all Ju90s were taken over from Luftwaffe.
In April 1939 the RLM asked Junkers for a further developement of the Ju90 for military transport purposes. The Ju90V5 and V6, also known as Ju90B were the prototypes of this military design. They got a new wing and a BMW139 engine instead of the older BMW132. Modifications were also made at the tail unit and the undercarriage. The V5 flew first on December 5th 1939. A special equipment of the Ju90V6 was a boarding ramp in the floor of the fuselage. This ramp could be used to load cars and larger cargo freight. A further two prototypes (V7, V8) were ordered by Luftwaffe. Again these prototypes were equipped with a modified wing with increased span. The V8 was also equipped with machine gun towers for self defense. Actually the Ju90V8 was introduced as the Ju90 bomber version, known as Ju90S. These two prototypes flew first in September 1941. Delays were caused due to intensive modifications of the original Ju90 design and probably due to problems with the developement of the Ju88 programme. Junkers got an additional RLM request for a further two prototypes (V9, V10), which seemed to be dropped at the beginning of WWII.
Military transport/bomber variant (V5,V6 and V7), with BMW 139 (1550hp) due the problem with this powerplant was latter changed to BMW 801C (1660hp)
This armed transport was the prototype for the future Ju-290.
It had a MG-151 and 5x MG-131. The wingspan was increased 7 meters.
This sturdy, capacious airplane, was used for a highly important transportation missions in 1940 by the Frachtsonderdienst Wien and Kurierdienst Spanien – a couple of specific half-military subsidiaris of the Deutsche Lufthansa, that sustained till the very end of war.
