BATAN ISLAND, Philippines—The Air Force C-130 transport plane dipped down on the sun-baked airfield of this remote island in the northern Philippines, delivering a weapon system designed to give the U.S. an edge in the intensifying superpower standoff in the Pacific. The Navy-Marine Expeditionary Ship Interdiction System, or Nmesis, is an antiship missile launcher mounted on a remote-controlled truck. The dumbbell-shaped islet where it landed lies just 120 miles south of Taiwan. For the Marines, the Nmesis’s flight to Batan was a key test in a high-stakes retooling aimed at readying the military’s rapid-response force for a war with China in some of the world’s most strategic, but increasingly tense, waterways. The prospect of an armed conflict with China—whether over Taiwan, the self-governed democracy Beijing claims as its own, or the contested shipping lanes of the South China Sea—has the U.S. playing catch-up. While American forces were bogged down in Iraq and Afghanistan, China built up the world’s biggest navy and a formidable arsenal of missiles aimed at making swaths of the Pacific off-limits to its adversaries.(https://www.wsj.com/world/asia/nmesis-missile-system-us-china-pacific-ce7e1f7c?mod=Searchresults_pos1&page=1)
