development

The trigger for the development was the Lockheed Vega type , which reached a cruising speed of 290 km / h in high-speed traffic. Following an order from the Reich Ministry of Transport (RVM) on October 3, 1931, the construction of three Ju 60 aircraft began. Hermann Pohlmann was responsible for the execution , the management was in the hands of Ernst Zindel . A Pratt & Whitney Hornet A radial engine with 404 kW, built under license by BMW, was selected as the drive . In addition to the two crew members, six passengers could be carried.

The test sample Ju 60V1 (serial number 4200) was unsatisfactory and it is not certain whether it was ever completed and tested. The second prototype with the serial number 4201, referred to as the Ju 60/1 in the work documents, met the demands placed on it earlier. It was probably used on the first flight on November 8, 1932 by Junkers' works pilot Wilhelm Zimmermann. After 37 hours of flight it was taken over by the RVM and handed over to Lufthansa . With the registration D-2400 it was used on freight routes for test purposes. From the end of 1934 it was used on passenger routes with the registration D-UPAL. He was given the nickname "Arrow" and was kept in service until 1936. Ultimately, however, the appearance of the much faster Heinkel He 70 caused Luft Hansa to lose interest in this type. The third prototype with the serial number 4202 was not completed and was used as the basis for the improved Junkers Ju 160 .

The Ju 60 was the last type of aircraft to be developed in the Junkers factories under the direction of Hugo Junkers .
