The US military will deploy its NMESIS ground-based anti-ship missile system to Yonaguni, Japan's island closest to Taiwan, during the Keen Sword exercise on 19–29 October. The SCMP reports it as a first-time move amid Beijing–Tokyo tension; a Washington Examiner columnist presents it as a welcome boost to deterrence.

The story, neutrally told
Centre · 1The US will deploy the Navy-Marine Expeditionary Ship Interdiction System (NMESIS), a ground-based uncrewed anti-ship missile platform, to Yonaguni Island in Japan's Okinawa prefecture during the biennial Keen Sword exercise, according to the regional bureau of the Japanese defence ministry.

South China Morning PostN “NMESIS will also return to Ishigaki as part of the Keen Sword exercise, which runs from October 19 to 29.” Read at South China Morning Post ↗ Washington ExaminerR “NMESIS will arrive on Yonaguni for the Oct. 19-29 U.S.-Japan “Keen Sword” military exercise” Read at Washington Examiner ↗ Centre · 1The South China Morning Post says the move brings the system closer to Taiwan than last September's Resolute Dragon drills, when NMESIS was stationed on Ishigaki Island, roughly 240km from Taiwan; it will also return to Ishigaki for Keen Sword. South China Morning PostN “The deployment during the Keen Sword joint exercise moves the system closer to Taiwan than during the Resolute Dragon joint drills in September last year.” Read at South China Morning Post ↗
Centre · 1The Okinawa Defence Bureau said the deployment supports training at the Yonaguni garrison, including a joint coordination centre, island-defence tabletop drills and coordination with Japanese and US equipment at other garrisons; it said details could change. South China Morning PostN “the NMESIS deployment will support training at the Yonaguni garrison”“specific training details remained subject to change” Read at South China Morning Post ↗ Centre · 1US forces will also make their first deployment of the Marine Air Defence Integrated System (MADIS), a short-range air-defence weapon, to Yonaguni, and Tokyo is separately moving to station air-defence missile units there.

Mixed · 2The SCMP notes that in a conflict the system could threaten ships operating east of Taiwan, where Beijing has stepped up coastguard patrols and naval activity; the Washington Examiner's columnist Tom Rogan argues that from Yonaguni its range covers waters off Taipei and north-eastern Taiwan. South China Morning PostN “could threaten enemy vessels trying to operate east of Taiwan” Read at South China Morning Post ↗ Washington ExaminerR “NMESIS’s range covers waters off the Taiwanese capital of Taipei and throughout northeastern Taiwan.” Read at Washington Examiner ↗ Centre · 1The deployment comes as Beijing–Tokyo relations are at their lowest in decades after Prime Minister Sanae Takaichi said in November that a Chinese attack on or blockade of Taiwan could be a "survival-threatening situation" for Japan; on Monday Chinese Foreign Minister Wang Yi urged Tokyo to correct its leaders' "erroneous words and deeds". South China Morning PostN “Ties between Beijing and Tokyo remain at their lowest point in decades following Japanese Prime Minister Sanae Takaichi’s controversial remarks about Taiwan in November.”“correct the erroneous words and deeds of its leaders on the Taiwan question as soon as possible” Read at South China Morning Post ↗ Mixed · 2Chinese foreign ministry spokesman Guo Jiakun said in April that Japan was building a "forward fortress of military confrontation"; the Washington Examiner cites Global Times quoting a retired PLA officer who said the deployment could raise the risk of miscalculation but that Yonaguni's small size would make NMESIS units easy to target. South China Morning PostN “This is essentially an attempt to build a forward fortress of military confrontation which threatens regional peace and stability” Read at South China Morning Post ↗ Washington ExaminerR “increase the risk of miscalculation by reinforcing perceptions that Japan and the U.S. could intervene militarily in the Taiwan question” Read at Washington Examiner ↗
Right · 1Rogan disputes the targeting point, arguing the units could fire from open ground and relocate into the island's forested southern hills, and says NMESIS is "not a war winner" but adds friction to Xi Jinping's calculations. Washington ExaminerR “NMESIS units could fire in open areas and then quickly relocate into concealed positions in the forest to avoid retaliatory fire.”“To be clear, NMESIS is not a war winner.” Read at Washington Examiner ↗ Centre · 1NMESIS was previously deployed at the Philippines' Batanes Islands during this year's Balikatan exercise, and a Pentagon update to Congress on 22 September said the US continues to strengthen "deterrence by denial along the First Island Chain". South China Morning PostN “US forces also deployed NMESIS during their joint annual Balikatan exercise with the Philippines earlier this year.”“we continue our efforts to strengthen deterrence by denial along the First Island Chain” Read at South China Morning Post ↗ Right · 1The Washington Examiner adds that Australian, British, Canadian and French forces will take part in Keen Sword, with Germany sending only medical and logistics personnel, and that the Marine Corps this month signed a $404 million deal with Kongsberg to produce and sustain Naval Strike Missiles through 2034.

Where accounts differ
-
Whether NMESIS on Yonaguni would be easy for China to target
- Centre
- The SCMP reports Chinese analysts' warnings about NMESIS as a sea-denial tool and does not assess its vulnerability.
- Right
- Rogan argues that mobile launchers and forested hills would let units relocate and survive, countering a retired PLA officer's view that the island's small size makes them easy targets.
-
Whether the deployment is a provocation or a deterrent
- Centre
- Presents it as unprecedented and as occurring amid simmering Beijing–Tokyo tensions, citing Beijing's criticism of Japan's missile deployments.
- Right
- Presents it as a needed boost to deterrence and a signal of support for Takaichi, meant not 'to provoke war'.
