Long Range Discrimination Radar (LRDR)

Abstract

The mission of the Long Range Discrimination Radar (LRDR) program office is to define, develop, acquire, field, and sustain the LRDR as an element of the BMDS supporting robust homeland defense (RHD). Initial fielding of the LRDR Configuration 1 is planned for 2020 with an Operational Capability Declaration projected in the 2022 time frame. The LRDR provides persistent long-range midcourse discrimination, precision tracking and hit assessment to support the RHD Capability against long-range missile threats in the Pacific theater. The LRDR is comprised of a LRDR Equipment Shelter (LES), housing two radar array faces, a Mission Control Facility (MCF) which supports radar operations, and supporting facilities and infrastructure. The Secretary of the Air Force approved Clear Air Force Station, Alaska as the LRDR site. The Air Force Space Command (AFSPC) has been designated as the Lead MAJCOM. The LRDR operates in S-band frequencies, features scalable and open systems architecture to mitigate evolving threats, and is integrated into the BMDS through the C2BMC system. This Program Element includes BMDS threat discrimination improvements, which will enhance BMDS effectiveness against the evolving threat. The end result will be a BMDS architecture more capable of discriminating and destroying re-entry vehicles with a higher degree of confidence, improving Warfighter shot doctrine, which will conserve homeland defense interceptor inventory. LRDR also supports additional mission areas including Space Situational Awareness. FY 2017 Amended Budget Request Justification: $+11.150M is required to address emergency warfighting readiness requirements to ensure readiness of the BMDS. $+11.150M Project MD96-LRDR/Long Range Discrimination Radar to purchase and install Front End Electronics (FEE) on the LRDR Primary Array to improve MDA's ability to adapt and mitigate threat growth with additional sensitivity without radar down time. Also improves system performance by reducing field installation cost (increased flexibility/supportability). Funds also provide removal of Polychlorinated Biphenyl-contaminated paint on structural steel encountered in Ballistic Missile Early Warning System (BMEWS) buildings (receive antennas not affected) in preparation for construction of LRDR.
