Long Range Discrimination Radar (LRDR)

Abstract

The mission of the Long Range Discrimination Radar (LRDR) program is to design, develop, integrate, deliver, field, and sustain the LRDR as an element of the Missile Defense System (MDS) Increment 6b Homeland Defense (HLD) Capability. This capability is representative of LRDR Configuration 1. Initial fielding of the LRDR is planned for 2020 leading to a Technical Capability Declaration (TCD) in FY 2021 and an Operational Capability Declaration (OCD) in FY 2022. Configuration 2 represents MDS Increment 6c/7 which includes software upgrades to LRDR to further improve discrimination techniques and capability, expand capability to a broader spectrum of threats, increase support to Space Situational Awareness and Space Object Identification, and implement cost reduction initiatives to reduce life cycle operating costs. Technical Capability Declaration for Configuration 2 is planned for FY 2024. 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) is the designated Lead Major Command (MAJCOM). The LRDR operates in the S-band frequency, features scalable and open systems architecture to mitigate evolving threats, and integrates into the MDS through the Command and Control, Battle Management, and Communications (C2BMC) system. This Program Element includes MDS threat discrimination improvements to enhance MDS effectiveness against the evolving threat. The result will be a MDS architecture more capable of discriminating and intercepting re-entry vehicles with a higher degree of confidence to improve Warfighter shot doctrine, and conserve Ground-Based Defense (GMD) interceptor inventory. LRDR also supports additional mission areas including Space Situational Awareness.
