Daimler built scores of Mercedes aircraft engines but they also built 298 Friedrichshafen bombers under license and prototypes of several designs of their own, though none of them reached production.
Prototype aircraft from the Great War or shortly thereafter include:
- The R.I four-engine tractor-pusher bomber actually followed the R.II. It was tested in Jan-May of 1917 but was rejected. It was almost an identical copy of the Union G.I, and it was tested from late 1915 through mid 1917.
- The R.II four-engine tractor-pusher bomber was also based on the Union G.I. The R.II was tested in Nov'16-April'17, but the design was abandoned. Two of them may have been built before testing was abandoned in mid 1917.
- The G.I saw partial work but was probably never completed.
- The tractor-engined G.II saw its first tests in November 1916 but proved difficult to fly and may have been abandoned after the first flight test. A pusher version fared no better.
- The Daimler G.III, with internal engines driving propellers through shafts and gears, also proved unsuccessful, and Daimler turned its attentions to license-built Friedrichshafen bombers.
