Base History \ Arrival

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.

Yuma Proving Ground is nearly halfway between Phoenix (178 miles) and San Diego (180 miles) and within about 300 miles of Tucson, Las Vegas, Mexicali, Palm Springs and Los Angeles. Yuma is in the Mountain Time zone, but note that Arizona does not observe daylight savings time except on the Navajo Reservation.



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.
