LRDR Operations Record of Decision (ROD) and Final Environmental Impact Statement


The Missile Defense Agency (MDA), as the lead agency, has signed the joint ROD along with the Department of Air Force (DAF), as a cooperating agency, to implement changes in operational concept for the Long Range Discrimination Radar (LRDR) located at Clear Air Force Station (CAFS), Alaska.

The MDA and DAF have selected the Proposed Action, as described in the LRDR Operations Final Environmental Impact Statement (EIS), to modify LRDR operational requirements and procedures to reflect continuous operations in response to emerging threats. This action will enable MDA to meet its congressional mandate to fully support the primary mission of the layered Missile Defense System to provide continuous and precise tracking and discrimination of long-range missile threats launched against the United States. The DAF and Federal Aviation Administration (FAA) were cooperating agencies to the EIS.
