According to a source in the Japanese Defense Ministry, Japan has refined the cost estimates for its two proposed Aegis Ashore batteries, indicating the actual cost may be twice the original estimate. The system, which the government aims to have operational by 2030, may come at a price of 400 billion yen alone, with the full project including interceptor missiles at a price close to 600 billion yen (5.4 billion USD). Earlier reports estimated the two Aegis Ashore sites to cost approximately 200 billion yen. The estimated cost increase comes after the selection of Lockheed Martin’s SSR radar earlier in July 2018. The SSR is the Aegis-integrated variant of the Lockheed Martin Long Range Discrimination Radar (LRDR).
