North Korea Builds New ICBM Engine to Boost Reach and Payload

South Korean officials revealed that North Korea has been working on a solid‑fuel engine designed for intercontinental ballistic missiles. The new engine is said to be heavier and stronger, giving the missile a longer range and the ability to carry several warheads at once. The government said the test took place on March 28, with the country’s leader present to applaud the advancement. The missile uses a lightweight carbon‑fiber frame, which keeps the overall weight down while maintaining structural integrity. This material lets the craft carry more explosives without sacrificing speed or accuracy. Analysts believe that the new engine delivers more thrust than earlier models tested in 2024, which were already capable of reaching the mainland United States.North Korea has traditionally launched long‑range missiles on steep trajectories so they splash in the ocean near its east coast or off Japan. This practice allows the country to test new rockets without flying them all the way to their intended targets. The recent engine test, however, suggests a shift toward more realistic trajectories that could actually reach distant targets. The country has repeatedly ignored United Nations sanctions that prohibit missile and nuclear tests. Each new development raises concerns among regional allies about the potential for more powerful weapons that could threaten civilian populations. South Korean lawmakers highlighted these concerns during a briefing by the National Intelligence Service, stressing that the new technology could change the strategic balance in East Asia. The government remains cautious as it monitors further developments from Pyongyang.
