Siemens-Schuckert D.IV


Biplane Fighter Aircraft


Aviation / Aerospace

The Siemens-Schuckert D.IV biplane fighter was still in production after the armistice was signed and is considered the best fighter design of the Great War.

The Siemens-Schuckert D.IV was a further development of the D-series brand, itself a copy of the spectacular French Nieuport 11. Development of the D.IV stemmed from the D.IIc short wing span prototype ordered after production of the D.I was complete. Performance was improved in the D.IV with new wings and added to the already impressive rate-of-climb that the aircraft would be known for. The D.IV appeared in serviceable numbers in August of 1918, just a few months before Germany's inevitable defeat.

Some 60 D.IV systems were on hand to see operational service with some 123 total examples eventually produced. The D.IV proved to have tremendous climbing capabilities and offered up an impressive service ceiling. Armament consisted of twin 7.92mm LMG 08/15 series machine guns while power stemmed from a Siemens-Halske Sh.III 11-cylinder geared rotary engine of 160 horsepower. Top speed was nearly 120 miles per hour and the aircraft maintained an endurance of 2 hours. In many respects, the system outperformed the challenging Fokker designs and ultimately was regarded as the best fighter design for either side in the whole of the war.

With Germany's capitulation by November of 1918, the armistice was signed and Germany was banned from any future aircraft production - though surprisingly the D.VI continued production through the middle of 1919. Switzerland purchased many surplus D.IV aircraft in the post-war years, keeping them operational well into the 1920's. In any regard, the D.VI can be seen as the pinnacle of the Siemens-Schuckert D-series with the original French Nieuport 11 design to thank for it.
