Among, the earliest specifications draw up by the C-Amt of Goring's "Luftfahrtkommissariat" was one calling for a lightweight single-seater for use emergency "Heimatschutzjager". The first prototype,the Ar 76a D-ISEN,was completed late in 1934,this being folowed in the spring of 1935 by a second prototype,the Ar 76a (D-IRAS). The general characteristics of the Ar 76 were adjudged exellent, but in the final evaluation of the designs,the Arado was placed second to the Fw 56.Nevertheless, a small production series of aircraft was ordered as a back-up for the Fw 56 programme,and these,delivered to the Luftwaffe in the spring of 1936,were used by the Jagdfliegerschulen FFS A/B 1,FFS A/B 8,FFS A/B 23 a LKS 1 Kaufbeuern, FFS A/B 32 Chrudim.
