Poster of the "Nieuport 17" french aircraft.

The Nieuport 17 was a French biplane fighter aircraft from the First World War. It was developed by Gustave Delage (Nieuport company) and it was put into service in March 1916.

The Nieuport 17 was derived from the Nieuport 12, equipped with a more powerful engine, larger wings and better structure. The first devices were equipped with a 110 hp (82 kW) engine, later with a 130 hp (97 kW) engine. It was a very maneuverable aircraft, but the lower wings tended to break during extreme maneuvers.

From March 1916 the Nieuport 17 was used by the French army but it was also adopted by most of the allied armies. Canadian ace Billy Bishop was awarded the Victoria Cross while driving a Nieuport 17.

The Germans, impressed by the performance of the French hunter, made a very faithful copy: the Siemens-Schuckert DI which was built in 94 copies.
