Derived from the 1929 fortress gun (itself a development of the old 1897 field gun) with a semi-automatic breech and an automatic loader added, the "high power" APX 75mm gun fired a mle 1915 HE round with a reduced charge at 400 m/s and the mle 1915 AP round at 570 m/s (50mm penetration at 1000 m) and its two sights and stereoscopic rangefinder allowed a direct fire range of 2000 m.
