The fairly large Gladiator factory was thus converted into an arms manufacture in 1915 and became the principal industrial producer of Chauchat machine rifles during World War I. Later on, in 1918, a subsidiary of Compagnie des forges et acieries de la marine et d'Homecourt named SIDARME and located in Saint-Chamond, Loire, also participated in the mass manufacture of CSRGs.
It is the homecourt to KFÍ (Basketball), Hörður (Team Handball) and Skellur (Volleyball) but also hosts several other events every year.
The SNCF Class BB 60031 diesel locomotives were built by Homecourt/Jeumont for the Chemin de Fer Paris-Lyon-Méditerranée in 1938.
