Intercept test successful

The U.S. military has conducted its first operational test of the THAAD missile defense system and the ship-based Aegis system aimed at intercepting two medium- range ballistic missiles fired almost simultaneously. The test was conducted early Tuesday in the western Pacific. Officials say the test was important because it demonstrated the ability of the U.S. military to defend against possible regional ballistic missile threats from countries like Iran or North Korea or even accidental releases.
