Escadrille SPA.124 of the French Air Force was founded circa 18 February 1918. The previous Escadrille N.124, more widely known as the Lafayette Escadrille largely transferred into the United States Air Service on 18 February as the 103rd Aero Squadron. The remaining French personnel were formed into a replacement unit operating SPADs. They were dubbed the Jeanne d'Arc unit to differentiate them from their famous predecessor. Escadrille SPA.124, the Jeanne d'Arc escadrille, continues in service in today's French Air Force.
