Mojave Anti-Aircraft Range

Mojave Anti-Aircraft Range. A major military testing area located within the Mojave Desert of San Bernardino County, California. Established during World War II, it has served as a critical site for the development and evaluation of air defense systems for the United States Armed Forces. The range's remote location and vast airspace have made it a premier facility for live-fire exercises and advanced weapons testing for decades.

History

The facility was established in 1944 by the United States Army Air Forces to provide a secure location for testing new anti-aircraft artillery and training gunners. Its creation was a direct response to the evolving aerial threats identified during World War II. In the post-war era, control transferred to the United States Army as part of the broader Fort Irwin military reservation. The range's mission expanded significantly during the Cold War to counter the perceived threat from Soviet bombers, leading to the testing of advanced systems like the Nike missile series. Throughout the latter half of the 20th century, it supported programs for the Strategic Defense Initiative and subsequent missile defense projects under the Missile Defense Agency.

Geography and facilities

Encompassing approximately 1,200 square miles, the range is situated in the central Mojave Desert, northeast of Barstow. The terrain is characterized by broad valleys, isolated mountain ranges like the Cady Mountains, and extensive alluvial fans. Key infrastructure includes multiple instrumented impact areas, radar tracking stations, and launch complexes for surface-to-air missiles. The range shares a boundary with the China Lake Naval Air Weapons Station and lies adjacent to protected public lands managed by the Bureau of Land Management. Its airspace is designated as the R-2508 Special Use Airspace Complex, one of the largest such military training areas in the United States.

Operations and testing

Primary operations involve live-fire testing of integrated air defense systems, including missile intercepts against drone targets. The range has been integral to the development of systems such as the MIM-104 Patriot, Terminal High Altitude Area Defense (THAAD), and various directed-energy weapons prototypes. Exercises often involve units from Fort Bliss and White Sands Missile Range, utilizing aircraft from Edwards Air Force Base and Nellis Air Force Base to simulate threat profiles. Testing is coordinated by the United States Army Test and Evaluation Command and frequently involves contractors like Lockheed Martin and Raytheon Technologies.

Environmental impact

The long history of munitions testing has resulted in localized contamination, with the United States Environmental Protection Agency listing portions of the range as a Superfund site. Primary concerns include soil and groundwater pollution from explosives like RDX and heavy metals such as lead and perchlorate. The Center for Biological Diversity has raised issues regarding the impact on desert species, including the desert tortoise and the Mojave fringe-toed lizard. Remediation efforts are overseen by the United States Army Corps of Engineers in conjunction with the California Environmental Protection Agency.
