WASHINGTON — In reaction to North Korea's growing missile capabilities, the Pentagon will try to shoot down an intercontinental-range missile for the first time in a test next week. The goal is to more closely simulate a North Korean intercontinental ballistic missile aimed at the U.S. homeland, officials said Friday
The American interceptor has a spotty track record, succeeding in nine of 17 attempts since 1999. The most recent test, in June 2014, was a success, but that followed three straight failures. The system has evolved from the multibillion-dollar effort triggered by President Ronald Reagan's 1983 push for a "Star Wars" solution to ballistic missile threats during the Cold War — when the Soviet Union was the only major worry.
North Korea is now the focus of U.S. efforts because its leader, Kim Jong Un, has vowed to field a nuclear-armed missile capable of reaching American territory. He has yet to test an ICBM, but Pentagon officials believe he is speeding in that direction.
U.S. Marine Corps Lt. Gen. Vincent Stewart, director of the Defense Intelligence Agency, said this week that "left unchecked," Kim will eventually succeed.
The Pentagon has a variety of missile defense systems, but the one designed with a potential North Korean ICBM in mind is perhaps the most technologically challenging. Critics say it also is the least reliable.
The basic defensive idea is to fire a rocket into space upon warning of a hostile missile launch. The rocket releases a 5-foot-long device called a "kill vehicle" that uses internal guidance systems to steer into the path of the oncoming missile's warhead, destroying it by force of impact. Officially known as the Ground-based Midcourse Defense system, the Pentagon likens it to hitting a bullet with a bullet.
