The US will deploy the Navy-Marine Expeditionary Ship Interdiction System (NMESIS) for the first time on Yonaguni Island, Japan, which is just 110 kilometers from Taiwan, during joint military exercises this month. This deployment marks a significant move compared to previous drills where NMESIS was placed farther east at Ishigaki Island, about 240 kilometers from Taiwan.

Story summary

The US will deploy its unmanned missile system called NMESIS on Yonaguni Island, located in Japan's Okinawa prefecture, during a joint military exercise from October 19 to 29, 2023. This deployment is part of the biennial Keen Sword exercises and marks the first time NMESIS will be stationed so close to Taiwan; Yonaguni is approximately 110km (60 nautical miles) from Taiwan's coast. Previously, during the Resolute Dragon drills in September 2022, NMESIS was positioned on Ishigaki Island, which is about 240km away from Taiwan and 127km east of Yonaguni.

NMESIS uses anti-ship missiles developed by Norway’s Kongsberg company, capable of penetrating advanced air defenses and targeting critical naval assets like sensors and control centers. The system's range extends at least 100 nautical miles, with future upgrades aiming to extend it beyond 150 nautical miles. This strategic move comes amid heightened tensions between Beijing and Tokyo, as China views the deployment near Taiwan as a direct challenge to its interests in the region.
