Yuma Proving Ground

Yuma Proving Ground (YPG), located in southwestern Arizona, was established in 1943 as the U.S. Army's Camp Laguna and the Yuma Test Branch to support World War II training and testing operations. During the war, the area was used extensively to test combat vehicles, weapons, and equipment in harsh desert conditions. After the war, the facility evolved into one of the Army’s premier test centers, supporting research and development for artillery, munitions, and vehicle systems. Today, Yuma Proving Ground is a critical asset for the U.S. Army, conducting year-round testing of military hardware for all branches of the armed forces and allied nations.
