French 155mm GPF Gun

The French 155mm GPF (Grande Puissance Filloux) was a heavy field gun used by the French Army and US Army and Marine Corps during the Great War and World War II. It was designed by the French engineer Colonel L.J.F. Filloux. In 1917, the United States switched to the metric system in artillery and began making the French 155mm GPF at home. During World War I, it was actively used in the field on the Western Front in 1917 and 1918 by both the French and US armies, but during World War II the United States used this gun only for coastal defense and defense of Allied territories such as Australia. France also deployed the 155mm GPF during WWII, but after the Battle of France in 1940, the Wehrmacht seized the 450 155mm GPF guns that the French had and began using them as their own for the rest of the war.
