Missile Defense Agency’s Long Range Discrimination Radar closer to delivery

CLEAR, ALASKA – The Missile Defense Agency’s (MDA) Long Range Discrimination Radar (LRDR) program has completed delivery of the first ten antenna panels to Clear, Alaska, that will make up the first of the system’s two radar antenna arrays. Lockheed Martin continues to successfully achieve all program milestones as it works towards delivering the radar to MDA in 2020. The system will serve as a critical sensor within MDA’s layered defense strategy to protect the U.S. homeland from ballistic missile attacks.

The two radar antenna arrays will be comprised of a total of 20 panels, each about 27 feet tall, measuring approximately four stories high and wide. Temporary structures have been assembled in front of the radar facility to ensure the panels are installed on schedule, regardless of weather conditions. The installation and integration of the radar system began last year and will be followed by the transition to the testing period.

Over 66% of program technical requirements have already been verified at Lockheed Martin’s Solid State Radar Integration Site (SSRIS). 

In 2018, LRDR achieved Technical Readiness Level 7 using a scalable and modular gallium nitride based “subarray” radar building block, providing advanced performance and increased efficiency and reliability to pace ever-evolving threats. Scaled versions of the LRDR technology will be utilized for future radar programs including Aegis Ashore Japan, recently designated AN/SPY-7(V)1, Canadian Surface Combatant, and Spain’s F-110 Frigate program.

LRDR combines proven solid state radar (SSR) technologies with proven ballistic missile defense algorithms, all based upon an open architecture platform capable of meeting future growth. The system will provide around-the-clock threat acquisition, tracking and discrimination data to enable defense systems to lock on and engage ballistic missile threats.
