The Canon de 194 GPF (Grande Puissance Filloux – meaning "High-Power" Filloux) holds the distinction of being France's inaugural tracked Self-propelled artillery piece. Conceived during the closing phase of World War I, it incorporated a variety of innovative characteristics for its time.

Design

This artillery vehicle was developed under the guidance of Colonel , who served as deputy CEO at the Compagnie des forges et aciéries de la marine et d'Homécourt based in Saint-Chamond. The 194 mm cannon, crafted by Louis Filloux at the Atelier de Construction de Puteaux, evolved from the earlier Canon de 155mm GPF. Initially designed as a heavy field artillery piece, only half of the barrels initially ordered were completed and adapted for mounting on the Saint-Chamond chassis following the conclusion of World War I.

A prototype featuring a 220 mm Saint-Chamond howitzer underwent trials but was ultimately rejected. The French military opted instead for both the 194 mm GPF and the 280 mm Schneider howitzer as their tracked self-propelled artillery solutions, balancing firepower with cost efficiency. These self-propelled guns consisted of two linked tracked units: an avant-train (front vehicle) responsible for ammunition transport, and an affut-chenille (gun platform). The lead vehicle incorporated a Panhard SUK4 M2 engine alongside an electrical generator, powering electric motors on both vehicles. Energy was transferred through a flexible cable connecting to the gun carriage.

When compared to contemporaneous systems such as the British Gun Carrier Mark I, the Canon de 194 demonstrated greater sophistication: it operated with a single driver, included hydraulic braking systems, and featured recoil mechanisms that automatically adjusted using pneumatic recuperators.

Service

Production commenced in April 1918. Just two days prior to the armistice, a version of the vehicle—lacking its Puteaux gun—was tested at the Saint-Chamond factory. By June 1919, delivery of a critical oscillating mass component manufactured at Puteaux was still pending to Saint-Chamond.

Throughout the interwar years, these vehicles were assigned to an artillery regiment stationed in Valence, operating alongside 280 mm self-propelled guns.

At the onset of World War II, 36 units remained operational; several were seized by German forces. Those that survived were incorporated into the Wehrmacht inventory under the designation 19.4 cm Kanone 485(f) Selbstfahrlafette. At least three saw deployment on the Eastern Front circa 1942. Additionally, two units were employed by Italian coastal artillery near Rome, identified as Cannone da 194/32.

The Germans also adapted some 194 mm barrels for use on French Mortier G de 270 Mle 1889 coastal defense mortar mounts. A limited number of 19,4 cm Kanone 485(f) pieces were assigned to coastal defense roles in Denmark.

Only one surviving specimen is preserved today and exhibited at the U.S. Army Artillery Museum located in Fort Sill, Oklahoma.
