Groundbreaking Missile Tracking System Triumphs After Extended Delays: Test Success Announced

Following a postponement of almost two years, the Missile Defense Agency has successfully conducted a test of the Long-Range Discrimination Radar (LRDR), confirming its capability to track a live ballistic missile target.

During a test on June 23 at the Clear Space Force Station in Alaska, the LRDR “successfully acquired, tracked, and relayed missile target data to the Command and Control Battle Management and Communications (C2BMC),” as per a Missile Defense Agency statement. “This test marked the radar’s inaugural flight test in which it tracked a live Intercontinental Ballistic Missile (ICBM)-like target.”

The missile target was launched from the air over the northern Pacific Ocean, traveling more than 2,000 kilometers (approximately 1,243 miles) towards the south of Alaska’s coast, according to the MDA.

Data gathered by the LRDR, alongside information from the Upgraded Early Warning Radar also situated at Clear Space Force Station, was transmitted to the Ground-Based Midcourse Defense (GMD) system as a component of the mock engagement, the agency reported.

The crucial test had been delayed from its original 2023 schedule due to a “target anomaly,” as Missile Defense Agency Director Lt. Gen. Heath Collins explained in an August 2024 interview with Defense News. “Following that, we conducted a tracking exercise the next month using a simpler target, which performed exceedingly well,” he added.

A primary concern for the agency was to accelerate the radar’s deployment after experiencing several setbacks, including disruptions caused by the COVID-19 pandemic, which had initially delayed the radar’s deployment scheduled for December 2021.

The spread of COVID-19 across the U.S. in March 2020 necessitated the suspension of all construction and integration efforts for the LRDR, pushing the program into a “caretaker status.” This meant only a minimal crew remained on-site to safeguard the equipment from environmental damage.

The successful completion of this test will now contribute to the decision-making process for integrating it into the operational framework for homeland ballistic missile defense. The formal operational acceptance of the LRDR by the U.S. Space Force was anticipated to occur by the end of 2023, prior to the cancellation of the original test event.

Once fully operational, the Lockheed Martin-developed LRDR will possess the capability to simultaneously detect and track multiple small objects, including all types of ballistic missiles over long distances, under continuous operation. It will integrate with both the GMD system and the C2BMC system.

The GMD system is structured to safeguard the continental U.S. against intercontinental ballistic missile threats originating from countries like North Korea and Iran.

Additionally, the LRDR will aid in space domain awareness by monitoring various space activities such as satellites in orbit, discarded rocket components, and debris fragments. Moreover, although not currently a specified requirement, a software update could potentially enable the LRDR to detect and track hypersonic weapons.
