During the first World War US Army purchased French 75 mm field guns to equip its expeditionary force. In the spring of 1918 US industries started domestically producing them, designated 75 mm Gun M1897, but only a few of these reached Europe before the end of hostilities. It remained in production and was iteratively improved with A2, A3, and finally A4 models.
While the gun itself had seen some minor changes, the A4 carriage had new pneumatic tyres, steel wheels, a lower profile and internal expanding brakes. This allowed the gun to be issued to motorised artillery units instead of horse-drawn ones, but didn't solve the major issue of the gun: its low maximum elevation.
