Japan is seeking powerful new radar
from the US to boost the operational range of its planned procurement of a land-based version of the Aegis
ballistic missile defense (BMD) system. So far, previous efforts by Tokyo to acquire the AN/SPY-6 AESA radar have not come to fruition, leaving them to rely on existing radar technology that has less range than a new generation of BMD interceptor missiles. While the US Navy are seemingly behind Japan receiving the technology, there may be a reluctance from the MDA, which is responsible for developing BMD technology, to release such advanced technology before it is fully fielded by the US. Developed by Raytheon and integrated into the Aegis system by Lockheed Martin, SPY-6 radars will form part of the Pentagon's new Arleigh Burke-class destroyers
, due to be operational in 2022. In order for Japan to receive the Spy-6 in time for its planned deployment of its Aegis Ashore system in 2023, it will need to be cleared long before that 2022 date, in order to give the manufacturers time to build the system.
