– Defense News – Taiwan’s F-16s face a growing threat from China’s arsenal of surface-to-air missiles (SAMs). The latest and gravest is the Russian sale of 400-kilometer-range S-400 Triumf road-mobile SAM systems to China. If fielded in Fujian Province, the SAM system will be able to cover the whole of Taiwan airspace, thus finally solving the “problem of air superiority for the Chinese.”
