The Nieuport 17 was a French biplane fighter aircraft of World War I, manufactured by the Nieuport company.
The type reached the French front in March 1916, and quickly began to replace the Nieuport XI in French service. It was also ordered by the Royal Flying Corps and Royal Naval Air Service, as it was superior to any British fighter at that time. During part of 1916, the Nieuport XVII equipped every fighter squadron of the Aviation Militaire. By early 1917, the Nieuport was outclassed in most respects by the latest German fighters. Nieuport XVII fighters in many French squadrons were replace by mid-1917.
Nieuport XVII was ordered by the Royal Flying Corps and Royal Naval Air Service. It also served in other allied air services.
