PYONGYANG, North Korea — North Korean leader Kim Jong Un has overseen a ground test of an upgraded high-thrust solid-fuel rocket engine, state media reported, in a move analysts say could significantly enhance the country’s long-range missile capabilities.
According to the Korean Central News Agency (KCNA), the test forms part of Pyongyang’s ongoing five-year defence development plan and involved a carbon-fibre composite engine capable of producing a maximum thrust of 2,500 kilonewtons. The agency did not disclose the exact timing or location of the test.
KCNA described the demonstration as evidence of growing military strength, stating it showed the country’s readiness to match adversaries with overwhelming force. The report underscores North Korea’s continued focus on advancing its strategic weapons programme despite international pressure and sanctions.
Military analysts say high-thrust solid-fuel engines are a critical component in modern missile systems, particularly intercontinental ballistic missiles (ICBMs). Compared to liquid-fuel systems, solid-fuel engines allow for faster launch times and require less preparation, making missiles more difficult to detect and intercept.
The latest test marks the first confirmed high-thrust solid-fuel engine trial since September, when North Korea reported a lower-thrust version. The progression suggests steady technological advancement in propulsion systems, a key factor in achieving reliable long-range strike capability.
During the visit, Kim also inspected special operations forces training exercises and reviewed a newly developed main battle tank, signalling broader efforts to modernise both strategic and conventional military assets.
As North Korea presses ahead with its weapons development agenda, the latest engine test highlights the strategic importance of propulsion technology in shaping the balance of power and the evolving nature of modern missile systems.
