Escadrille 31 of the French Air Force was founded at the beginning of the World War I, on 24 September 1914, at Dijon Air Base. Once equipped with Morane-Saulnier Ns, it was posted to I Armee of the French Army.

In February 1915, Escadrille MS 31 was moved to defense of Verdun. In April 1915, it returned to I Armee; on the 26th, it began re-equipping with Nieuport 18 two-seaters. By January 1916, the Escadrille 31 had rearmed with ten single-seater Nieuport 11s. When the unit acquired Lieutenant de Villeneuve as commander in mid April, he instituted the use of a Roman archer as the escadrille insignia. In October, Escadrille N 31 shifted to support II Armee. The following month, the unit was incorporated into Groupe de Combat II. Escadrille 31 began receiving SPADs on 7 January 1917. However, it would not totally rearm with SPADs until 17 September, when it was renamed Escadrille SPA 31.

The escadrille would serve as part of GC II through the remainder of the war. When the armistice came, it had been credited with 42 aircraft and four observation balloons destroyed, and have earned two citations from Army Corps.
