North Korea Tests Missile Engine, Raises US Threat

North Korea has tested a new high-thrust solid-fuel rocket engine as leader Kim Jong Un continues efforts to expand the country’s long-range strike capabilities.

State media outlet Korean Central News Agency reported the test involved a carbon-fiber-based engine designed to support more advanced missile systems capable of reaching the U.S. mainland.

Officials said the engine generated approximately 2,500 kilonewtons of thrust, surpassing a similar test conducted last year. Analysts say such technology could enable more mobile, faster-launching, and harder-to-detect intercontinental ballistic missiles.

Kim described the test as a key step in strengthening North Korea’s “strategic military muscle,” part of a broader five-year defense plan aimed at upgrading its nuclear and missile arsenal.

The development is expected to heighten tensions with the United States and regional allies, as concerns grow over Pyongyang’s advancing missile technology and expanding deterrence posture.
