Japan announced it has deployed Patriot Advanced Capability-3 surface-to-air interceptors (PAC-3) in response to North Korea’s recent missiles launches.

The battery was moved to a Ground Self-Defense Force camp in the city from an Air Self-Defense Force base about 70 km away, apparently because the interceptors only cover a range of roughly several dozen kilometers.

The Patriot Advanced Capability-3 surface-to-air interceptors are designed to shoot down ballistic missiles before they land and are there to back up Japan’s sea-based Standard Missile-3 systems if they fail to intercept their targets in outer space.
