The Mortier de 150 mm T Modèle 1917 Fabry was the standard French Heavy trench mortar of World War I. It remained in service through 1940, with some 1,159 available during the Phony War.

Design

[edit]

The tube was supported by two recoil-recuperators in a flask-rocker assembly that was mounted on a platform with six fixed spades. The finned mortar "bomb" was loaded from the muzzle, but the propellant was loaded from the breech and ignited by a percussion ignition system.[1]

For transport it was broken down into three loads, each towed on machine gun carts by either one horse or eight men. Each cart also carried twenty 17-kilogram (37 lb) bombs.[1]
