The gun carriage was originally the 3-inch model of 1913, which was later designated the 3-inch M1916. The gun was modified to a 75 mm bore, permitting interchangeability of ammunition with French guns. Its hydrospring recoil system, called the St. Chamond type, consisted of an oil cylinder on top of the barrel and two spring cylinders underneath. The gun remained in army inventory as late as 1942.

51 of these weapons were mounted on 2.5-ton White trucks for anti-aircraft (AA) use, designated the AA truck mount M1917. Some of these weapons reached France before the Armistice, the only US-made AA weapons to do so, but none saw action. Prior to the commencement of this program, 50 AA truck mounts were shipped to France without guns as a stopgap, where French 75s were mounted on them. The maximum AA altitude was 5,500 yd (5,000 m) at 82° elevation, limited by a 20-second fuse. The low muzzle velocity and limited elevation and traverse of the AA mounting (31° to 82° elevation, 240° traverse) impaired the weapon's effectiveness. By 1940 the AA version of the weapon was no longer in active service, but a few were retained for training.
