was founded at Teltow near Berlin by Karl Bomhard, who had previously participated in the design of the Lohner arrow-biplanes (Pfeilflieger) in Austria.
[1] At the successful Idflieg inspection on 13 April 1915, the airframe construction was described as good but the low cruising and maximum speeds were criticised as well as the disappointing useful load.
The strengthened second G.I, stationed at Schneidemuhl, flew soon after but was destroyed just before landing on 1 September 1915 after experiencing extreme vibrations from the engines during flight.
Development continued as the Daimler R.I but on 1 August 1916 the Union-Flugzeugwerke went into liquidation and its assets were taken over by the Norddeutsche Flugzeugwerke, which spent the remainder of the war years repairing aircraft.
