The Canon de 155 Grande Puissance Filloux (GPF) mle.1917 was a 155 mm cannon used by the French Army during the first half of the 20th century.
The gun was designed during World War I by Colonel Louis Filloux to meet France's urgent need for modern heavy artillery, and became the standard heavy field gun of the French Army from 1917 until World War II.
It was also manufactured in the USA from 1917, after the US switched to metric artillery based on French patterns. It was used by the United States Army and United States Marine Corps as their primary heavy artillery gun under the designation 155 mm Gun M1917 or M1918 until 1942, when it was gradually replaced by the 155 mm M1A1 'Long Tom'. US Army forces in the Far East (USAFFE) such as the 301st FA Regiment (Philippine Army) and the 86th FA Regiment (Philippine Scouts), and also US Coast Artillery units (91st and 92nd CA Regiments, Philippine Scouts) used this artillery piece against the Japanese invasion of the Philippines in 1941-42. Some of the guns were originally emplaced in "Panama Mounts" on Corregidor, Caballo, and Carabao islands on the entrance of Manila Bay. A number of them were removed from their emplacements and used as "roving batteries" and gave effective counterbattery fire. The gun was later mounted on a self-propelled mount as the M12 Gun Motor Carriage and saw action in 1944-45.
During World War II, some US-made guns were used for coast defence of US and allied territories, such as Australia, typically on "Panama" mountings - circular concrete platforms with a raised centre section, with the carriage tyres pivoting around the centre section and the split trails spread out on rails at the platform's edge.
In 1940, France fielded 450 of these guns. Many of them were captured and used by Germany for the rest of the war. In German service it was known as the 15.5 cm K 418(f); it served with heavy artillery battalions and on coastal defense duties. A battery of six of these guns were the cause of the actions at Pointe du Hoc in June 1944.
