Japan boosting missile defense to face North Korean threat

Intercept systems getting upgrade to handle high-flying missiles

| Japan

TOKYO -- Japan will overhaul its missile intercept command system starting in fiscal 2018 to cope with advancements in North Korea's weapons technology, such as faster-descending missiles launched at a steeper trajectory.

The Japan Aerospace Defense Ground Environment, or JADGE, detects incoming missiles via radar and combines that information with data from American military satellites and other sources to determine the rockets' trajectory and likely point of impact. If the missiles are expected to strike Japan, land- and ship-based interceptors are ordered to shoot them down.
