Aviatik D.I

The Aviatik (Berg) D.I, was a single-engine, single-seater biplane fighter that was developed and manufactured by the Austro-Hungarian branch of German aircraft company Aviatik. It was also known as Berg D.I or the Berg Fighter, because it was designed by Dipl. Ing. Julius von Berg, and to distinguish it from the D.I fighter built by the parent Aviatik firm in Germany. The D.I was the first locally designed fighter aircraft to be adopted into the Austro-Hungarian Air Service (Luftfahrtruppen). It was manufactured both in-house and under license by a number of subcontractors. In 1917, the D.I entered Austro-Hungarian service and saw active operations in the final years of the First World War; it was commonly used for aerial reconnaissance missions, as many fighter units continued to prefer using the German-designed Albatros D.III conducting air superiority operations. Following the end of the conflict, it was adopted by the Hungarian Air Force, the Royal Romanian Air Force and the Royal Yugoslav Air Force.
