AVIATIK (BERG) D II Austria-Hungary

  Featuring a fuselage virtually identical to that of the D I, the DII was flown as a prototype in the summer of 1917, this, the Aviatik 30.22, actually employing much of the structure of the 30.21 (see D I). The DII was characterised by a short-span cantilever lower wing, and a series of 19 aircraft was built for frontline evaluation, these being powered by either the 200 hp (Series 39) or 225 hp (Series 339) Austro-Daimler engine. A four-bladed Jaray propeller was fitted, and armament consisted of the usual paired Schwarzlose 8-mm guns. The first three series aircraft were tested in November 1917, and seven were evaluated at the front, but the decision that O-UF Aviatik should licence-manufacture the Fokker D VII terminated any plans to build the DII in quantity. One DII airframe was experimentally fitted with a 200 hp Hiero engine as the Aviatik 30.38, and participated in the July 1918 D-Contest. With the 225 hp Austro-Daimler engine the D II attained 137 mph (220 km/h). The following details relate to the 200 hp version.
