The Arado Ar 64 was a single seat biplane fighter, developed in the late 1920s.
It was among the first fighters produced when Germany abandoned the restrictions of the Treaty of Versailles and began rearming.
The Ar 64 was a derivative of the earlier Arado SD II and Arado SD III, based upon the Reich War Ministry requirement for a successor to the Fokker D.XIII fighter.
The AR 64D and 64E would the first fighters built in quantity by Germany since the end of World War I.
The two differed, as the 64D had a revised undercarriage and a four blade propeller, and the 64E had a two blade propeller attached to a direct drive version of the Jupiter VI radial engine.
