It was one of very few pre-war US artillery designs selected for wartime production in World War I, although (as with most of these projects) few of these weapons were delivered to France and used in action.

[2][3] By the time production probably ceased on 17 April 1919, of 960 guns and 1,148 carriages ordered from 1906 through early 1917, only about 209 guns and 470 carriages were completed, according to the official history of US World War I war production, America's Munitions 1917–1918.

[2] Sixty-four of these weapons (48 from pre-war stocks)[2] were shipped to France to equip three regiments, of which two (the 302nd and 328th Field Artillery) saw action with 48 guns total.

[1] The official history does not mention switching the 4.7-inch gun to French ammunition, but does note that 994,852 4.7-inch shells were produced by the US through 1 November 1918; many of these may have been for British consumption.

[4] The majority of the weapons were probably used for training in the United States, as shipments from the US to Europe were primarily men and ammunition.
