[2] In 1916 the manufacturing company Lohner-Werke of Vienna was given a contract from the Luftfahrttruppen to design and build a single seat fighter based around the 185 hp (138 kW) Austro-Daimler six-cylinder inline engine.

[1] Work was begun on the first airframe, serial number 111.01, and on 5 September 1916 the Lohner 10.20 was unveiled at Aspern.

[1] The fuselage was short and deep of laminated wood construction, armed with twin synchronized Schwarzlose machine guns.

[1] In August 1917 the Luftfahrttruppen commandeered 10.02B and official trials continued through October when further development of this airframe ended.

[1] Due to the lackluster performance, further development was halted and the Luftfahrttruppen assigned Lohner-Werke a licence to produce the Aviatik (Berg) D.I.
