The US bought 1,503 French Canon de 155 C modèle 1917 Schneider and used them in WWI as their standard field howitzer. In addition to these weapons, the US also produced 626 under license as the 155mm Howitzer M1918. It differed from the French howitzer having a straight gun shield and rubber tyres instead of steel tyres on the spoked wheels.Between the wars, the M1918 was upgraded with metal wheels, pneumatic tyres to allow them to be towed by motor transport.They continued to serve until 1942
