Developed from Aviatik D.I

The Aviatik (Berg) D.II, the prototypes of which were known as Aviatik 30.22 and Aviatik 30.38, was an Austro-Hungarian fighter plane prototype towards the end of the First World War.

Development

The D.II's fuselage was virtually identical to that of the D.I. It was characterised, however, by its short-span cantilever lower wing. Through 1917, 19 D.IIs were built for front-line evaluation. The series 39 aircraft were powered by the 149.14 kW (200 hp) Austro-Daimler 200hp engine and the series 339 aircraft by the 167.78 kW (225 hp) Austro-Daimler 225 hp engine driving a four-bladed Jaray propeller and armed with the usual paired 8 mm (0.315 in) Schwarzlose machine guns. A further prototype, (30.38), was produced by fitting a 149.14 kW (200 hp) Hiero engine in a D.II airframe.

Operational history

The first three production aircraft were tested in November 1917, and seven were evaluated at the front later in that year, showing good promise. However, the decision was made that Aviatik should instead produce the Fokker D.VII, and any plans to continue production of the D.II were halted.
