The 4.7in Field Gun M1906 was designed and issued by the US Army Ordnance Department in 1906.

Design[edit]

Barrel construction
Breech mechanism

The design was orthodox for its time with a box trail and hydro spring recoil system. When the United States entered World War I 60 had been produced and issued to the army. Once the US entered WWI the US Army came under pressure to adopt French artillery systems and the 4.7in Field Gun was rechambered to fire French 120mm ammunition. The switch to French 120mm ammunition eased logistical problems due to the availability of French ammunition. However the decision to change ammunition upset production and only 16 new pieces were finished before the end of the war.

Ammunition[edit]
