Long Range Discrimination Radar

Special Use Airspace Environmental Impact Statement

The 2014 National Defense Authorization Act requires Missile Defense Agency (MDA) to deploy an LRDR system to improve the U.S. defense against ballistic missile threat. An LRDR is capable of midcourse identification, classification, and discrimination of ballistic missile threats. The MDA in coordination with the U.S. Air Force and Federal Aviation Administration is preparing an Environmental Impact Statement (EIS) to inform a decision on the design of additional Special Use Airspace (SUA) necessary for the operation of Long Range Discrimination Radar (LRDR) at Clear Air Force Station (CAFS) in Alaska.

Additional SUA for operation of the LRDR requires MDA to prepare an EIS in accordance with the National Environmental Policy Act (NEPA) of 1969. As part of the NEPA process, the public has the opportunity to review and comment on the proposed additional SUA and the potential environmental impacts associated with the additional SUA.

The purpose of the additional SUA at Clear Air Force Station is to support LRDR operations and provide protection from high intensity radiated fields (HIRF) for aircraft operating in the vicinity.

This action is needed as the LRDR’s original operational concept did not take into account the planned change in operational tempo and expanded threat space necessary to meet evolving threats. The MDA requires the land-based LRDR to support fielding of enhanced homeland defense capability as a key component of the BMDS.

As this EIS process moves forward, please continue to check back on this site for updates, handouts, news releases and official reports.


The MDA encourages all interested members of the public, as well as federal, state, tribal and local agencies, to participate in the scoping process for the preparation of this EIS.

The MDA will host scoping meetings in the local communities of Anchorage, Anderson, and Fairbanks, Alaska to share information about the EIS process, gather feedback, and solicit comments on the scope of the environmental analysis.

A Notice of Intent has been published in the Federal Register on May 17, 2019.
