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.
- The R.II four-engine tractor-pusher bomber was based on the Union G.I. The R.II was tested in Nov'16-April'17, but the design was abandoned.
- 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.
