The Siemens-Schuckert Dr.I was a German single seat triplane fighter aircraft first flown in 1917. Its development and that of a more powerful, uncompleted variant, was abandoned after a flight test programme. Design and developmentThe Dr.I was a single seat triplane developed at the same time as the Siemens-Schuckert D.II. It used the flat sided fuselage of the earlier Siemens-Schuckert D.I biplane rather than that of the rounded D.II. Like the D.I the Dr.III was powered by a {{convert|110|hp|kW|abbr=on|0}} Siemens-Halske Sh.I nine cylinder rotary engine. The fighter was first flown in July 1917. Later in its development programme the Dr.I crashed and was seriously damaged. Siemens-Schuckert rebuilt it, though adding 2.90 m2 (31.2 sq ft) to the wing area. Construction of a version powered by a more powerful {{convert|110|hp|kW|abbr=on|0}} Siemens-Halske Sh.III eleven cylinder rotary engine, the Dr.II, was well advanced when it was abandoned.
