The Nieuport 27 was a French biplane fighter aircraft during World War I designed by Gustave Delage. The model 27 was the last of the line of Nieuport "V-strut" single seat fighters stemming from the Bébé of early 1916. A few operational examples supplemented the very similar Nieuport 24bis in operational squadrons in late 1917 but most examples of the type served as advanced trainers.

As Described In
Knights of the Sky: The Nieuport 27 was the logical successor to the Nieuport 17. It was the first Nieuport fighter to have a circular section fuselage and a fixed vertical tail fin. It was also the first Nieuport fighter to have twin synchronized Vickers machine guns. The Nieuport 27 never really competed with its earlier cousin the 17, and few made it to the front; Allied pilots preferred the Spad 13. The US bought most of the nearly 400 that were built.
