Long Range Discrimination Radar
The Long Range Discrimination Radar (LRDR) in Alaska is part of the United States's Ground-Based Midcourse Defense anti-ballistic missile system. The main contractor is Lockheed Martin, under a US$784 million contract from the Missile Defense Agency in October 2015.
LRDR is a gallium nitride (GaN)–based, solid-state active electronically scanned array (AESA) early-warning radar that allows for continuous coverage, even when it is undergoing maintenance. The radar consists of individual solid state radar blocks that can be combined to scale up the size of the radar. The multi-purpose GaN device used on the prototype version of the LRDR is from the Japanese electronics company Fujitsu, according to Lockheed Martin.
Construction in Alaska for the LRDR was scheduled to begin in 2019, tentatively at Clear Space Force Station in central Alaska. Each AESA's dimensions are 60 feet (18 m) high by 60 feet (18 m) wide; the field of view is 220 degrees.
In late February 2021, the Missile Defense Agency said that the radar installation was underway, with Initial Operational Capability to be achieved in 2021. Testing for Full Operational Capability is expected by 2023.
In mid-August 2023, the Flight Test Other-26 (FTX-26) was cancelled due to an anomaly with the live ballistic missile target. When operational, the LRDR will be tied into the Ground-Based Midcourse Defense system and the Command and Control, Battle Management and Communications system.
The LRDR may become part of Golden Dome.
The AN/SPY-7(V)1 is the official designation of an LRDR-derivative used with the Aegis Ballistic Missile Defense System. On 30 July 2018, the Japanese government approved a plan to purchase two pairs of AN/SPY-7(V)1 for the Aegis Ashore facility and will be installed in Yamaguchi Prefecture and Akita Prefecture. The first operation is expected to start from 2025, by Japan Ground Self Defense Force.
Missile Defense Agency has also decided to use AN/SPY-7(V)1 for the Aegis Ashore to be installed in Hawaii. Derivatives of the AN/SPY-7(V)1 will be used on the Canadian River-class destroyer and the Spanish F-110 frigate.
