It was characterised by it's short span cantilever lower-wing and a pre-series of 19 airplanes were built for it's frontline evaluation. that were powered by either the 200hp Austro-Daimler series 19000 (series 39) engine or the 225hp Austro-Daimler series 19000 (series 339). Only eleven airplanes of the series 39 were made and just six of the 339 series were produced.
It was also fitted a four bladed Jaray propeller and it was armed with the usual 8mm Schwarzlose 07/12 machine guns. The first prototype was flown in November 1917 and seven of them were evaluated at the front, but it was decided that the ÖAW (the main manufacturer of this airplane), should manufacture under license the Fokker D.VII, terminating this way any possible development of the Berg D.II. Apparently, one of them was fitted with a 200hp Hiero engine, was known as the Aviatik 30.38 and took part in the July 1918 D-Type contest, unfortunately we couldn't find graphical evidence of this, so it's left undrawn. With the 225hp engine, it achieved the speed of 220km/h, a new record for the Austro-Hungarian airplanes of the time.
