Design and development

The A 35 was a development of a series of Junkers aircraft from 1918, starting with the J10/J11, the A 20, A 25, A 32, and finally the A 35. It was originally intended as a two-seat multi-purpose fighter aircraft and made its first flight in 1926. Due to the post-war restrictions, Hugo Junkers and the Soviet Government signed a contract about the setup of an aircraft facility at Fili in Russia in December 1922. In 1926, the first Junkers L5 engines were mounted on the Junkers A 20s. With some further tail modifications the new aircraft was designated as A 35. A total of 24 aircraft were originally built as A 35s. A number of A 20s and A 25s were also modified with the Junkers L5 engine. The A 35 was also available with a
