The Dr.I series however was largely an experimental triplane fighter. The first Euler triplane, powered with 160 h.p. Oberursel U III, the designation was not official, neither is it completely certain.
The Euler Dr 1 apparently stayed at prototype stage, designed by Julius Hromadnik, the first being under test in the summer of 1917, competing with the Hansa-Brandenburg Dr.I and DFW Dr I. It was not accepted for service.
The Euler Type C a reconnaissance aircraft with a pusher engine of 1913-14. The initial form with nose turret of the Euler two-seat fighter of 1915 intended primarily for anti-airship and escort missions.
The final form of the Euler two-seat fighter of 1915 with faired, pulpit-like gun position, intended primarily for anti-airship and escort missions.
Euler C-type under test in mid-1916: note the armament of two parabellum machine guns. This, along with the Spandau, was a very effective aerial weapon and a success for German machine gun technology. Only one machine was built.

The Euler B.III was built in 1918 for training as a licence-built L.V.G. B.III, but with a considerable stagger, and a 120 hp Mercedes D II engine.
An early wartime reconnaissance type was the BII tractor biplane (built at Frankfurt in late 1914), an early version of which had tricycle landing gear.
About 50 were built in 1915.
