Naval missile defence gets higher ability to intercept ballistic missiles

Test comes a day after North Korea fired ballistic missile over Japan

The US Missile Defence Agency (MDA) and the Navy successfully conducted a missile defense test off the coast of Hawaii, the MDA said in a statement on Wednesday.The test, scheduled well in advance, was done from the USS John Paul Jones and comes a day after North Korea fired a ballistic missile over Japan.The test, using Standard Missile-6 guided missiles, intercepted a medium-range ballistic missile target.North Korea said its missile launch was to counter US and South Korean military drills, and was a first step in military action in the Pacific to "contain" the US territory of Guam. The launch was condemned by the United Nations as an "outrageous" act.The MDA said the test gives the naval component of the missile defense system higher ability to intercept ballistic missiles in their terminal phase.
