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.[1]
LRDR is a gallium nitride (GaN )-based, solid-state active electronically scanned array (AESA) early-warning radar [1] [2] Fujitsu , according to Lockheed Martin.[3]
Construction in Alaska for the LRDR was scheduled to begin in 2019,[1] Clear Space Force Station in central Alaska.[4] [5]
In late February 2021, the Missile Defense Agency said that the radar installation was underway, with Initial Operational Capability to be achieved in 2021.[6] Full Operational Capability is expected by 2023.[5]
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 .[7]

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 .[8]
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 Surface Combatant and the Spanish F-110 frigate .[9]
In September 2020, AN/SPY-7(V )1 was chosen by Canada as the primary radar for its future Canadian Surface Combatant (CSC) along with CMS-330 Combat Management System with Aegis Combat System .[10]
Lockheed Martin promoted this version of radar as the AN/SPY-1 refurbishment program to the US Navy to extend the lifespan of the Ticonderoga -class cruiserArleigh Burke -class destroyer[11] AN/SPY-6 AESA radar from Raytheon was selected to retrofit Flight IIA Arleigh Burke destroyers; the same radar is used on Flight III ships.[12] [13]
