WASHINGTON, D.C.: The US military is preparing to conduct another test of a missile-intercept system in Alaska, the Pentagon said Monday, amid continued tensions with North Korea over its ballistic missile program. Pentagon spokesman Navy Captain Jeff Davis said a routine test of the Terminal High Altitude Area Defense (THAAD) system had been scheduled to go ahead “soon.” A notice to mariners put out by the US Coast Guard said the test could occur as soon as Saturday. THAAD is designed to intercept and destroy short-, medium- and intermediate-range ballistic missiles during their final phase of flight. THAAD is not designed to stop an ICBM—that job is left primarily to the Ground-based Midcourse Defense (GMD) interceptor system. Missile Defense Agency Director Lieutenant General Sam Greaves said in a statement the test would occur at the Pacific Spaceport Complex, Alaska.
