The Nieuport 24 was an attempt by the Nieuport firm to prolong the success of its line of sesquiplane fighters.
It is believed that the prototype's tail surfaces had caused problems either during manufacturing or flight-testing. While the design of the tail surface was being revised a Nieuport 24 was fitted with the tail and balanced rudder of the Standard Nieuport 17. The modified airframe was designated the Nieuport 24bis. The A.E.F. Air Service purchased 140 Nieuport 24bis. These were used as a fighter trainer and served with the 31st Aero Squadron. Original public domain image from Flickr
