North Korea conducts engine test for missile capable of striking US mainland

North Korea conducted an engine test for a long-range missile under the observation of leader Kim Jong Un, according to state media, marking another step in the country's weapons development program. The test involved a high-thrust, solid-fuel engine designed to enhance Pyongyang's ability to strike the US mainland, a capability that has been a stated goal of North Korea's military modernization efforts. Such propulsion advances are significant because solid-fuel engines are more reliable, faster to launch, and harder to detect than liquid-fuel alternatives, making them militarily advantageous. The test underscores North Korea's continued pursuit of nuclear-armed missiles capable of reaching American territory, despite international sanctions and diplomatic pressures. The development is likely to draw concern from the Trump administration and US allies South Korea and Japan, who view North Korea's missile program as a direct threat.
