The Fort Irwin area has a history dating back almost 15,000 years, when Native Americans of the Lake Mojave Period were believed to live in the area. Native American settlements and pioneer explorations in the area were first recorded when Father Francisco Garces, a Spaniard, traveled the Mojave Indian Trail in 1796. During his travels, he noted several small bands of Indians and is believed to have been the first European to make contact with the Native Americans of this area.

Jedediah Smith is thought to have been the first American to explore the area in 1826. A fur trapper, Smith was soon followed by other pioneers traveling the Old Spanish Trail between Santa Fe and Los Angeles. Bitter Springs, on the eastern edge of Fort Irwin, was a favorite stop over site.

In 1844, Captain John C. Fremont, accompanied by Kit Carson, was the first member of the US Army to visit the Fort Irwin area. Captain Fremont established a camp near Bitter Springs that served travelers on the Old Spanish Trail, and later the Mormon Trail, linking Salt Lake City to California. This camp was later to become an important supply center for pioneers during California's settlement and gold rush.

The California Gold Rush brought prosperous trade and unexpected trouble to the area. As California grew, and more travelers used the trails to enter the territory, raids and horse stealing became a problem. In 1846, the Army's Mormon Battalion patrolled the Fort Irwin area to control the raiding and horse stealing. During the Indian Wars the Army constructed a small stone fort overlooking Bitter Springs and patrolled the Fort Irwin area.

In the 1880s the area experienced an economic boom with the discovery of borax at Death Valley. From the late 19th century to the early 20th century, the area began to grow tremendously as mining operations of all types flourished. Soon railroads, workers, and businesses led to the establishment of the nearby town of Barstow.

The years following the Indian Wars were quiet militarily. In 1940, President 57th Field Artillery Brigade during World War I, and it was subsumed into the Desert Training Center as one of its cantonment areas and some of its ranges. Two years later, Camp Irwin was deactivated and placed on surplus status.

Camp Irwin reopened its gates in 1951 as the Armored Combat Training Area and served as a training center for combat units during the Korean War. Regimental tank companies of the U.S. 43d Infantry Division from Camp Pickett, Virginia were the first to train at the new facility.

The post was designated a permanent installation on 1 August 1961 and renamed Fort Irwin. During the Vietnam buildup, many units, primarily artillery and engineer, trained and deployed from Fort Irwin.

In January 1971, the post was deactivated again and placed in maintenance status under the control of Fort MacArthur (Los Angeles), California. The California National Guard assumed full responsibility for the post in 1972. From 1972 to late 1980, Fort Irwin was used primarily as a training area by the National Guard and reserve components.

National Training Center

On 9 August 1979, the Department of the Army announced that Fort Irwin had been selected as the site for the National Training Center. With over 1,000 square miles (2,600 km2) for maneuver and ranges, an uncluttered electromagnetic spectrum, airspace restricted to military use, and its isolation from densely populated areas, Fort Irwin was an ideal site for this facility. The National Training Center was officially activated 16 October 1980, and Fort Irwin returned to active status on 1 July 1981.

Since its activation, the National Training Center has witnessed many firsts. The first units to train against the MOUT (Military Operations in Urban Terrain) mission was conducted at the National Training Center Pioneer Training Facility in December 1993.


During the re-opening of the National Training Center in 1980, the OPFOR consisted of a detachment of infantry from the 7th Infantry Division US Army based in Fort Ord, California, and a detachment of the 72nd Armor. Once the US Army turned to regimental units in 1985, the OPFOR was designated the 177th Armored Brigade (SEP). The OPFOR soldiers wore Soviet-style armor uniforms including black berets and Soviet-style insignias, and used M551 Sheridan tanks visually modified to resemble BMP-1 vehicles and T-72 tanks. Units from the U.S. Marine Corps (USMC) and the U.S. Army Reserve and Army National Guard would support infantry roles for the OPFOR. Air support and air combat tactics came from USAF fighter units operating from Nellis AFB and USMC attack and fighter/attack units operating from MCAS El Toro and MCAS Tustin. When those USMC installations were closed as a result of Base Realignment and Closure Commission actions in the mid-1990s, USMC air support shifted to MCAS Miramar and MCAS Camp Pendleton. The National Training center at that period also showcased US Army large-scale tactics to foreign military leaders from all over the world. The OPFOR ran 15 training rotations a year against armored brigades from all over the USA. The command centers of the large-scale battles were computerized in a central command post, where each battle was recorded and analyzed.

The National Training Center and Fort Irwin continue to serve as the Army's premier training center. Since the September 11, 2001 attacks, the National Training Center has transformed to focus on continuous counterinsurgency operations that reflect the ongoing and rapidly changing battlefield.

Also, the Canadian Forces use the training facilities in order to prepare for its role in Afghanistan,[3] as part of their pre-deployment training

It is a common tradition for any military unit visiting the installation to paint a design on one of the large rock formations near the main gate. Units of all types and locations are represented.

One of the features of the base is the presence of several mock "villages" which are used to train troops in urban warfare prior to their deployment. The villages are supposed to mimic real villages from Iraq and Afghanistan and have variety of buildings such as mosques, hotels, traffic circles, etc. filled with Arabic-speaking actors playing villagers, street vendors, and insurgents. The biggest two are known as Medina Wasl[4][5] and Medina Jabal,[6][7] and are located several miles from Fort Irwin. Most of the buildings are created using intermodal containers, like lego, but some are much more elaborate and are actually built to Iraqi building standards.[8]

Fort Irwin Solar Project

Fort Irwin Solar Project will be the largest renewable energy project in the Department of Defense's history. The initial development plan is expected to result in more than 500 MW of renewable energy with one billion kilowatt-hours (kWh) of solar power generated per year by 2022. The $2-billion Fort Irwin Solar Project will create jobs both during construction and long-term plant operations, as well as generate additional revenue for local businesses.[9]


Fort Irwin has a total area of 2,579.77 km² (996.055 sq mi), with only 0.3277 km² of this area as water, according to the United States Census Bureau, however the CDP covers an area of 7.1 square miles (18.3 km²), all of it land.

Within its territory on its western side lies the Goldstone Deep Space Communications Complex. The ZIP Code is 92310 and the reservation is inside area codes 442 and 760.
