Japanese army will conduct training with Patriot PAC-3 missile.

According to the Asian Review website, Japanese defense forces will conduct missile intercept training Tuesday in Hokkaido following North Korea's repeated firing of ballistic missiles through that airspace.

The Japan Air Self-Defense Force will carry out the drill at the Erimo Sub Base in the northern Japanese island. The exercise will involve the Patriot Advanced Capability-3 surface-to-air interceptor system, which can be deployed swiftly via mobile launching vehicles.

There are 34 PAC-3 units in Japan. They represent the second line of defense against an incoming rocket in case the sea-based Aegis missile shield, maintained by the Japan Maritime Self-Defense Force, fails to intercept the target. The PAC-3 has a lateral range of up to about 40km.

In August, North Korea launched a suspected medium-range missile that flew over Hokkaido's Cape Erimo and eventually traveled some 2,700km. The regime then fired a missile in September that took a similar trajectory and traveled 3,700km.

The PAC-3 (Patriot Advanced Capability) is an upgrade of the American Patriot air defense missile system developed by Raytheon to improve capabilities of Patriot missiles against ballistic missiles. The PAC-3 Missile is a high velocity interceptor that defeats incoming targets by direct, body-to-body impact. PAC-3 Missiles, when deployed in a Patriot battery, significantly increase the Patriot system’s firepower, since 16 PAC-3s load-out on a Patriot launcher, compared with four Patriot PAC-2 missiles.
