There is no component of U.S. forces here with the mission to directly defend Japan. For example, the 7th Fleet is based at Sasebo and Yokosuka to maintain American naval supremacy in the Western Pacific and the Indian Ocean. The Marines, which are used in land warfare, ride aboard their ships. They do not defend Okinawa. The fighter aircraft at Kadena Air Base (Okinawa Prefecture) and Misawa Air Base (Aomori Prefecture) are deployed to the Middle East. All of Japan’s air space is defended by Air SDF. In Okinawa the U.S. Air Force’s ammunition depot at Kadena and the Navy’s storage facilities at White Beach have nothing to do with defending Japan.
