The Nieuport 24 C.1 was a French single-seat biplane fighter aircraft that was used in World War I.
The Nieuport 24 was developed by Gustave Delage at the Societé Anonyme des Établissements Nieuportand was based on the Nieuport 17. Like its predecessor it was equipped with V-shaped interplane struts, but unlike it, the Nieuport 24 had an improved aerodynamic design with rounded wingtips and ailerons. It was powered by a 130 horsepower Le Rhone rotary engine. It was equipped with a synchronized 7.7 mm Vickers machine gun, the British variant was fitted with an additional Lewis machine gun, which was mounted on the top of the upper wing.
