North Korea conducts test for missile it claims can target US mainland

North Korea conducted a test Sunday of an upgraded solid-fuel missile engine that the regime claims can reach the U.S. mainland, according to state media. The engine generated 2,500 kilonewtons of thrust, a significant increase from a September test that produced 1,970 kilonewtons. Solid-fuel engines are strategically important because they allow faster launch times and easier deployment compared to liquid-fuel alternatives, making missile systems more difficult for adversaries to detect and intercept. The test represents North Korea's continued advancement of its long-range missile capabilities at a time of elevated tensions on the Korean Peninsula and repeated U.S.-North Korea standoffs over nuclear weapons development. The regime regularly announces weapons tests through state media as part of its strategy to project military strength and deter what it characterizes as Western aggression.
