The Canon de 155 Grande Puissance Filloux mle.1917 was a 155 mm cannon used by the French Army during the first half of the 20th century. Following the French surrender, the captured 155mm GPF guns were obtained by the Wehrmacht, and reclassified as the '15.5-cm K 418(f)'. Having been originally introduced in 1917, the captured pieces were usually relegated to coastal defense or heavy artillery battalions. By 1944, over 50 guns were emplaced on the beaches of Normandy.
