PYONGYANG — North Korea has successfully conducted a ground jet test of a newly developed high-thrust solid-fuel engine, marking a significant leap forward in its ambition to field a more sophisticated class of intercontinental ballistic missiles (ICBMs).
State media reports confirmed the test took place at the Sohae Satellite Launching Ground, supervised by leader Kim Jong Un. The successful trial of the large-capacity engine is seen as a critical technical milestone for the regime’s strategic weaponry program, specifically aimed at developing a new-generation ICBM capable of striking the United States mainland with greater speed and less warning.
Unlike liquid-fueled missiles, which require a lengthy fueling process visible to satellite surveillance, solid-fuel missiles can be stored pre-loaded and launched almost instantly. This “cold-launch” capability makes the weapons significantly harder for international intelligence agencies to detect and intercept.
During the inspection, Kim Jong Un expressed high expectations that a new type of strategic weapon would be developed in the “shortest span of time.” He praised the scientists and engineers for providing a “sure guarantee” for the completion of another strategic weapon system.
The test comes amid heightened tensions on the Korean Peninsula, following a record year of missile launches and intensified joint military drills between the U.S. and South Korea. International observers warn that the development of a solid-fuel ICBM represents a major shift in the regional balance of power, as it would provide Pyongyang with a more survivable and responsive nuclear deterrent.
Neighboring countries, including Japan and South Korea, have voiced deep concern over the latest development. Defense analysts suggest that while North Korea has previously displayed solid-fuel short-range missiles, scaling that technology up to an intercontinental range remains a complex engineering challenge that the regime is now aggressively pursuing.
As the North continues to ignore calls for denuclearization talks, this latest engine test signals that the country remains committed to its five-year military development plan, which prioritizes the diversification and modernization of its nuclear arsenal.
