Junkers A 35 was a two-seater cantilever monoplane, used for postal, training and military purposes.

The aircraft was designed in the 1920s by Junkers in Germany and manufactured at Dessau and by AB Flygindustri in Limhamn, Sweden and conversions from A 20s were made in Fili, Russia.

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.

It was equipped with a Junkers L5 engine and a machine gun over the rear seat by AB Flygindustri in Limhamn and this version was designated as the Junkers/AFI R53.

Some were delivered to Turkey as modified A20s, a further 20 aircraft went to Russia and 21 militarized R53 were sold to China.
