WASHINGTON — The U.S. will conduct two major defensive weapons tests in May 2017 in preparation for possible North Korean attack. <br /> <br />The first will see an upgraded Standard Missile fired from a U.S. Navy vessel somewhere in the Pacific. This improved projectile comes equipped with an enhanced warhead and booster, meaning it can cover greater distances, reported CNN. <br /> <br />The other test will see ground-based defenses in California and Alaska run through a theoretical North Korean strike on the U.S. mainland.These long-range interceptor missiles are said to have had a fifty-fifty success rate in previous tests.
