Union

The Union company produced a single four-engine bomber prototype, but its crash on 1 September 1915 spelled the end of the company. The chief designer, Karl Schopper, moved to Daimler and helped produce the similar Daimler R.I and R.II.

Aircraft from the Great War or shortly thereafter include:

• Union G.I or R.I
