Missile Defense Agency approves preliminary design, 'dual-pol' tech for LRDR

摘要

The Missile Defense Agency has approved Lockheed Martin's preliminary design for the Long Range Discrimination Radar -- a program central to Pentagon plans to improve homeland defense by bolstering the Ground-based Midcourse Defense program with an unprecedented ability to detect ballistic missile threats by the end of this decade. The LRDR is a nearly $1 billion project to emplace a new radar in Alaska by 2020 as part of the agency's plans to upgrade the GMD program to what it calls the Robust Homeland Defense configuration by providing an improved persistent view of long-range ballistic missiles ~ particularly those launched from North Korea -- during the midcourse of flight.
