On July 9, Japan’s Ministry of Defense said it would share information from its planned Aegis Ashore sites with the United States. The Japanese government first announced plans to acquire the system in 2017 and aims to build two Aegis sites in Akita and Yamaguchi prefectures. Japan already operates several shipborne Aegis systems and co-develops the system’s SM-3 Block IIA interceptor with the United States.
