The U.S. Army’s Yuma Proving Ground is one of the largest military installations in the world. The proving ground holds testing of nearly EVERY weapon system in the ground combat arsenal.


The U.S. Army Yuma Proving Ground is located near the Arizona-California border, adjacent to the Colorado River, approximately 24 miles north of the city of Yuma, Arizona. Situated in the southwest portion of the state, the proving ground is in the heart of the great Sonoran desert. This is a military town and cost of living is moderate. Yuma is the largest city in Arizona outside the metro areas of Phoenix and Tucson.  Yuma is the county seat and largest city of Yuma County.

Modern military equipment testing in Yuma can be traced back to 1943, when the U.S. Army Corps of Engineers opened the Yuma Test Branch. The area was also a portion of General George Patton’s California-Arizona Maneuver Area, used to train soldiers for service in World War II. Yuma Army Airfield was also established nearby to train fighter and bomber pilots. The name was changed from Yuma Test Station to Yuma Proving Ground in 1963. On June 19, 1974, YPG was designated a Department of Defense Major Range and Test Facility, becoming one of 26 ranges and test facilities so named.


Yuma proving ground (YPG) is part of the U.S. Army Test and Evaluation Command and is a multiple purpose test facility. Specific proving ground capabilities include testing of: artillery, mortars, mines, ground and aircraft weapons, target acquisition and fire control systems, wheeled and tracked vehicles, and air delivery materiel, equipment and techniques. There is only one unit assigned to YPG (Support Detachment) and thee tenant activities. See the Major Unit Listings for more details.
