North Korea Tests High-Power Missile Engine and Specialized Warheads

North Korea recently finished a series of tests to improve its long-range missiles. On March 29, the country tested a new solid-fuel engine that provides more power. This engine is built to help missiles reach the United States mainland more quickly and with less warning. In early April, military leaders also tested new types of warheads. These tests included cluster-bomb warheads and an electromagnetic weapon system. These new tools are meant to strengthen the country's military and its ability to damage power grids and military targets.
