Lockheed Martin completed initial exercises with the AN/SPY-7(V)1 radar system for Japan on March 22. The exercises included the U.S. Department of Defense, Missile Defense Agency, and Japan's Ministry of Defense, focusing on the detection, identification, acquisition, tracking, and discrimination of aerial targets.
The radar will be installed on the first of two new Aegis System Equipped Vessels. These tests follow earlier ones conducted between 2024-2025, which involved tracking the Lincoln Calibration Sphere in space. The AN/SPY-7(V)1 operates in the E/F band (2-4 GHz) and features advanced semiconductor transceiver modules made from gallium nitride, optimizing detection range and resolution for tracking space objects and ballistic missiles.
