The SPAD S. XII or SPAD 12 was a French single-seat biplane fighter aircraft of the First World War developed from the successful SPAD 7 by Louis Béchereau chief designer of the Société Pour L'Aviation et ses Dérivés (SPAD). The SPAD 12 was inspired by the ideas of French flying ace Georges Guynemer who proposed that a manoeuvrable single-seat aircraft be designed to carry a 37 mm cannon a weapon which had previously been mounted only in large two-seat aircraft such as the Voisin III.
Made by SPAD.
It is the successor of the SPAD S.VII .
