United States officials have confirmed that a test of the advanced SM-3 Block IIA missile defense system in Hawaii on Wednesday has failed, proving unable to intercept test intermediate-range missiles out of the air. The missile is used to target intermediate range missiles.
A test of a USA missile interceptor failed in Hawaii on Wednesday, a defense official said, marking the second such unsuccessful attempt in less than a year.
The official said it was still unclear why the test failed, adding that a full analysis of the experiment is still underway. Raytheon's Standard Missile-3 Block IIA interceptor is still in development as a joint project with Japan.
A combination photograph shows screenshots from a cellphone displaying an alert for a ballistic missile launch and the subsequent false alarm message in Hawaii on January 13.
The mistake was not stopped by the Hawaii emergency management agency's computer systems because there is little difference between the user interface for submitting test alerts and the one for sending actual alerts.
Hawaii's Emergency Management initially blamed the worker for pushing the wrong button, but investigators now say the man actually believed there was a missile heading for Hawaii.
Pyongyang has test-fired ballistic missiles on lofted trajectories into the sea around Japan multiple times, and officials said it would be very hard for Japan's current anti-missile defense systems to shoot them down if they were to threaten the country's territory. "North Korea's reckless pursuit of nuclear missiles could very soon threaten our homeland", Trump said during the speech.
The U.S. military also conducted an unsuccessful missile intercept test in June past year after carrying out a successful one the previous February.
The Pentagon has not publicly admitted the reported failure because of ongoing tensions with North Korea.
The secretive state, led by Kim Jong-un, have vowed to strike at the USA if they feel under threat.
