To defeat a Chinese invasion fleet, the Taiwanese military would need to sink half of the attacking ships. But sinking potentially hundreds of vessels would require an arsenal of no fewer than 1,200 anti-ship missiles. Those were the conclusions of a deep analysis the Taiwanese government conducted last summer under the auspices of the so-called “Joint Theater-Level Simulation System.” But new delays mean it could take years for Taipei to acquire all the missiles it needs.
