May 1918 - summer 1919
|Number of pieces:||
The Siemens-Schuckert D.IV was a single-seater fighter designed by Siemens-Schuckertwerke for the German air force from the final phase of the First World War and was considered the best fighter aircraft of the German air force.
From the prototype version D.IIc and the previous model Siemens-Schuckert D.III , graduate engineer Harald Wolff developed an altitude fighter with narrower wings under the designation D.IV , of which 280 pieces were ordered. With the wings only 1 m deep, the speed performance is improved compared to the previous model without sacrificing maneuverability or altitude.
As a further variant, the designer Wolff presented the Siemens-Schuckert DV in May 1918 during the comparison flight in Adlershof . In 1919 two high-decker Siemens-Schuckert D.VI were tested, the type, equipped for the first time with dropping additional tanks, reached a top speed of 220 km / h, achieved a range of 450 km, climbed to an altitude of 8,000 m in just 8.3 minutes and received the name Siemens-Schuckert EI . At the same time, a three-decker Siemens-Schuckert Dr.I was developed, but not completed.
First World War
The first D.IV arrived in April 1918 at Jagdgeschwader 2 for front testing. The first series aircraft reached the front in August 1918, but only about 60 aircraft were used in the Jasta 11, 14 and 22 squadrons by the end of the war. The machine was not easy to land because of the large propeller and high chassis , but it only needed a short runway and was easy to control. The aircraft had excellent flight communities, especially at altitudes above 4000 m, which were even superior to those of the Fokker D.VII .
After numerous comparative tests, the Siemens-Schuckert D.IV was named the best fighter aircraft available in October 1918. By the end of the war, only 123 D.IV could be produced.

Series production continued after the end of the war and the machines that were no longer accepted by the military were sold to private customers. The Schweizer Flugwaffe acquired a number of aircraft and used them until the late 1920s.
