Federal officials are considering installing a radar missile-detection system in rural Southern Oregon.

On Friday, the U.S. Bureau of Land Management announced it would “set aside” almost 5,000 acres for the U.S. Department of the Air Force to build the system. It will be part of a network of cutting-edge radars that can detect hypersonic missiles over the curvature of the Earth.

The Air Force is eyeing three sites in Oregon — two in Lake County, and one in Malheur County — as well as sites in Idaho and Nevada.

The Air Force first announced it would study the environmental effects of these “over-the-horizon” radars in April, then held a handful of public meetings in Oregon, Nevada and Idaho the following month. The department plans to make a decision by the end of 2027.

“The Proposed Action is needed urgently in the Northwest region to fulfill the mission to provide early detection of airborne threats approaching North America,” project documents say.

The project would be one of the few military facilities in Oregon outside of two Air National Guard bases.

The full radar system includes two main components: transmitters that release high-frequency radio waves, and receivers that capture reflected signals. The department plans to install two transmitter sites in Christmas Valley on 2,622 acres owned by the Oregon Military Department, and a receiver site in Whitehorse Ranch on 4,987 acres owned by the BLM.

The U.S. secretary of interior, who oversees the BLM, has the authority to withdraw federal lands from public use for military purposes without congressional approval if that withdrawn land is under 5,000 acres.

Preliminary field surveys in 2024 show the Oregon sites chosen for radar installations contain habitat used by five vulnerable species: the sage thrasher, burrowing owl, ferruginous hawk, pygmy rabbit, and Swainson’s hawk.
