Siemens Schuckert D.III. The Siemens-Schuckert D.III entered service in spring 1918 powered with an unusual 160 HP rotary engine. The 11-cylinder engine, developed by Siemens-Halske, offered two counter-rotating masses that cancelled out gyroscopic forces.
The Siemens-Schuckert D.III was a German single-seat fighter built by Siemens-Schuckert Werke. The D.III was a development of the earlier Siemens-Schuckert D.IIc prototype. The D.III was an (nearly) equal-span biplane powered by a 160 hp (119 kW) Siemens-Halske Sh.III bi-rotary engine.

Approximately 41 D.IIIs were delivered to frontline units between April and May 1918. Most aircraft were supplied to Jagdgeschwader II, whose pilots were enthusiastic about the new aircraft's handling and rate of climb. After only seven to 10 hours of service, however, the Sh.III engines started showing serious problems with overheating and piston seizure. The problem was later traced to the Voltol mineral oil that was used to replace the now-scarce castor oil. Furthermore, the close-fitting engine cowling provided inadequate cooling to the engine. In late May 1918, Jagdgeschwader II replaced its D.IIIs with the older Fokker Dr.I. The remaining D.III aircraft were returned to the Siemens-Schuckert factory, where they were retrofitted with new Sh.IIIa engines, an enlarged rudder, and cutaway cowlings that provided improved airflow. A further 30 new production D.IIIs incorporated these modifications. Total production amounted to 80 aircraft.
In July 1918, the D.III returned to active service as an interceptor with home defense squadrons. By this time, the D.III had been replaced in production by the Siemens-Schuckert D.IV.

The Siemens-Schuckert D-series fighters evolved from captured French Nieuport 11 aircraft. The D.III appeared as an improved D.I - a design that came too late to be of much use, and was therefore classified as a trainer. The D.III was developed from the longer-span D.IIc prototype, with smaller propellers and shorter landing gear.
The Siemens Schuckert D.III emerged from the various prototypes of the D.II, which were only built and developed to test the new Siemens & Halske Sh.III circulating motor. Only after the first deficiencies were corrected could the D.III prove itself as a good interceptor. Development and construction:
