Kim Jong Un supervises powerful rocket engine test in fresh weapons push

North Korean leader Kim Jong Un has overseen the ground test of an upgraded high-thrust rocket engine, according to state media, in what appears to be another major step forward in the country’s missile programme.

Defence analysts believe the solid-fuel engine is likely intended for intercontinental ballistic missiles (ICBMs), which can be launched more quickly because they require far less preparation before ignition than liquid-fuel systems.

State media said the test was conducted as part of North Korea’s broader national defence development plan under its current five-year strategy, though no details were given about the exact date or location.

The reported trial marks the first officially confirmed test of a high-thrust solid-fuel engine since September last year. At that time, North Korea said the engine had produced a maximum thrust of 1,971 kilonewtons. This latest test reportedly reached 2,500 kilonewtons, indicating a notable increase in power.

Analysts say the stronger engine points to Pyongyang’s continued ambition to develop missiles with global strike capability and improve its ability to challenge missile defence systems.

Images released by state media showed Kim inspecting components of the engine alongside officials, while another photo captured the engine firing at a ground test site, sending bright flames into the air.

The latest development has also renewed discussion over whether North Korea is moving beyond basic long-range missile capability toward systems capable of carrying multiple warheads. Experts note that heavier multi-warhead missiles require greater thrust, making this latest engine test especially significant.

North Korea last carried out an ICBM test launch in October 2024. Observers say a future launch would be needed to demonstrate whether the country has successfully advanced to a more sophisticated multi-warhead system.

In a separate report, state media also said Kim visited a special forces training base, where he observed military drills involving close-combat exercises and weapons training.
