The French Voisin 10 was an improved variant of the Voisin 8 2-seat pusher. The predecessor's Peugeot engine was found to be unreliable, but an excellent replacement was found in the 280hp Renault 12Fe used in the Voisin 10. The improved output allowed a larger fuselage and bomb load and a larger rudder. Roughly 900 Voisin 10's were built during the war, and they were very active in 1918 with several units, most famously as night bombers. The factory designated the Type 10 as the E.54 or the LAR.
