The U.S. on Tuesday test-fired its THAAD anti-ballistic missile system from Alaska that successfully intercepted a target missile launched from an Air Force Cargo plane north of Hawaii.
The drill was previously scheduled in June and comes a week after North Korea successfully test-launched an intermediate-range ballistic missile capable of hitting Alaska.
THAAD is used to intercept short- and intermediate-range ballistic missiles. It does not target intercontinental ballistic missiles. The U.S. has a perfect record on launches, hitting 14 out of 14 targets.
