South Korea's military has said North Korea's largest missile test yet used an older, smaller intercontinental ballistic missile, and not the massive new Hwasong-17 ICBM, in part to try to head off negative domestic reaction to a failed launch.
South Korean and U.S. officials have concluded that the March 24 launch appears to have been a Hwasong-15 ICBM, a defence ministry official said, speaking on condition of anonymity because of the sensitivity of the matter.
