# Nieuport 10

The Nieuport 10 (or Nieuport XB in contemporary sources) is a French First World War sesquiplane that filled a wide variety of roles, including reconnaissance, fighter and trainer.

## Design and development

In January 1914, designer Gustave Delage joined the Société Anonyme des Etablissements Nieuport, and started working on a series of aircraft that would remain in production for the remainder of the First World War. The Nieuport 10 was the first of these and was originally designed to compete in the Gordon Bennett Trophy race of 1914. World War I caused this contest to be cancelled, and the type was developed as a military two-seat reconnaissance aircraft that entered service in 1915.
The type featured a distinctive "V" strut layout. The lower wing was much smaller in area than the upper wing. The concept was intended to combine the strength, compactness and stability of the biplane's wire braced wing cell with the speed and ease of handling of the monoplane.
Many were built or converted as single-seat fighters by covering the front cockpit, and adding a Lewis Gun or Vickers machine gun either to fire through the centre section of the top wing or mounted over it, firing forwards. In this form, the type was used as a fighter.
Two major types were developed based on experience with the Nieuport 10 - the Nieuport 11 Bébé - a smaller and completely new aircraft, designed from the outset as a single-seater, and the Nieuport 12 - a more powerful two-seater with an enlarged top wing and improved seating for the gunner. In addition, production was undertaken later in the war of a dedicated trainer version under the Nieuport 83 E.2 designation with detail changes. A single example of a triplane, using a Nieuport 10 fuselage was built to test an unusual staggered wing concept.

## Operational use

Many of the early French aces flew the Nieuport 10, the best known of which was Georges Guynemer, who used several Nieuport 10s, all marked "Vieux Charles". Jan Olieslagers was flying a Nieuport 10 when he became the first Belgian to shoot down another aircraft, while the first Canadian aerial victory was also scored in a Nieuport 10, by Flight Sub-Lieutenant Arthur Ince.
